Dec 11, 2025
The tech industry is replete with various acronyms and concepts, which can often seem confusing and overwhelming. One of these is the Proof of Concept (PoC), a critical step in the product development cycle. So, what exactly is PoC? This article will delve into the concept, exploring its significance, steps involved, benefits, and potential drawbacks.
Understanding the Concept of PoC
A Proof of Concept (PoC) is essentially a small exercise or a project carried out to validate the feasibility and practical potential of a concept or idea. It serves as a method to demonstrate that a concept or theory can lead to useful results, which can be a product or a system. It is performed before full-scale production and is designed to prove that the concept can be developed successfully in the real world.
'The primary purpose of creating a PoC is to demonstrate the functionality and verify that a certain concept or theory has the potential of being used in a real-world scenario.'
Significance of Proof of Concept in Product Development
The importance of PoC, particularly in the field of software or product development, can't be overstated. It is a crucial decision-making tool that helps assess whether a concept or idea can be developed, identify potential technical and logistical issues that may interfere with the development process, and decide whether the project is viable from a cost perspective.
'Proof of Concept is often considered an insurance policy against wasting resources on a project that won't work.'
Steps involved in Developing a PoC
Developing a successful PoC involves several crucial steps: defining the main objectives and requirements, designing the PoC, executing the project, and finally, evaluating the results to determine the project's feasibility. The process may vary depending on the nature of the project, but these steps generally form the basis of any PoC development process.
'In developing a PoC, a successful end result is not necessarily the only indicator of success. It's equally valuable to learn what doesn't work as it is to discover what does.'
Advantages and Limitations of PoC
While PoC offers many advantages, it is also not devoid of shortcomings. Some of the key benefits of PoC include the potential to save time and resources, reduce risks, increase stakeholders' confidence, and improve the understanding of project requirements. On the downside, however, PoC can be expensive and time-consuming, especially if the concept does not prove to be viable. Additionally, the success of a PoC may not necessarily indicate that the full-scale product development will be successful.
'A Proof of Concept is simply that - a concept. It's not a full product or solution, and should not be used as such.'
Conclusion
In conclusion, PoC plays a critical role in the product development process, providing a valuable tool to assess feasibility and potential challenges of a concept before it goes into full production. However, like any tool, it is essential to utilize it correctly and understand its limitations to maximize its benefits.

In short, mobile app development services encompass the entire process of creating an app, from conception and design to development, testing, launch, and ongoing support. The choice between native, web, and hybrid apps, as well as the development approach, depends on the app’s specific requirements and goals.
Types of Mobile Apps
There are three main kinds of mobile apps:
Native Apps: These are made for a specific type of phone or tablet, like iPhone or Android. They work really well and can use all the features of the device, but making them for different types of devices can be expensive.
Web Apps: These are made using web technology and work in a web browser. They're cheaper and quicker to make but can't do as much as native apps.
Hybrid Apps: These are a mix of native and web apps. They put a web app into a native app shell so it can do a bit more than a regular web app. They can be made once and used on different devices, but might not work as smoothly as native apps.
Mobile App Development Platforms
There are two big platforms for mobile apps - iOS and Android:
iOS: This is what iPhones and iPads use. Apps for iOS can make more money, but you need to know specific programming languages and follow Apple's rules.
Android: This is used by many different brands of phones and tablets. It's more open than iOS, but there are so many different devices that it can be a challenge to make apps work well on all of them.
There are also cross-platform tools like React Native and Flutter that let you make apps for both iOS and Android at the same time. They're a good middle ground, but there might be some trade-offs in how well the apps work or how much you can do with them.

With the rise of digital technology and digital transactions, the way of doing business has drastically changed over the years. One of the latest additions to this revolution is the concept of Smart Contracts. These are self-executing contracts that exist within the blockchain network. Their core purpose is to facilitate reliable and traceable transactions without the need for middlemen or intermediaries.
Understanding Smart Contracts
Just like the traditionally signed contract, a smart contract is an agreement between two parties. But the difference is that these contracts are completely digital. A smart contract is a software program that directly controls the transfer of digital currencies or assets between parties under certain conditions.
"Smart contracts not only define the rules and penalties related to an agreement in the same way that a traditional contract does, but also automatically enforce those obligations."
How Smart Contracts Work?
Imagine a vending machine. You choose an item, insert money, and the machine automatically delivers your chosen item. A smart contract works in a similar fashion. It takes inputs (your chosen item and inserted money), processes them according to pre-set rules, and then spits out the result (delivers your chosen item). All of this happens autonomously, without intermediaries.
Advantages of Using Smart Contracts
There are multiple advantages of using smart contracts in your business, some of them are:
1. Trust
Smart contracts build trust between parties. As they are stored on a public database, tampering them is almost impossible. So, the two parties can fully trust each other.
2. Speed
Because smart contracts use software code to automate tasks, they can execute transactions faster than a traditional contract.
3. Savings
Smart contracts save you money since they knock out the presence of an intermediary. You would, for instance, have to pay a Notary to witness your transaction."
4. Security
Smart contracts use the highest level of data encryption currently available, which is the same standard that modern crypto-currencies use. This makes them extremely secure.
5. Accurate
As they are automated, smart contracts avoid the human error which can be present in manually filled out forms.
Smart Contracts and Your Business
Incorporating smart contracts into your business operations can streamline processes, and improve efficiency and transparency. Some examples include:
Supply Chain Management
Smart contracts can record and verify where a product has come from, tracing its journey from origin to your business, increasing transparency, and reducing the risk of fraud.
Real Estate
Complex processes like buying and selling property can be made easier and more transparent with smart contracts. They can reduce the amount of required paperwork and simplifying the process for everyone involved.
Insurance
Smart contracts can automate insurance claims and speed up processing, reducing waiting times and increasing customer satisfaction.
Healthcare
Smart contracts can be used to manage patient records, ensuring privacy and security, and allowing instant access to those records when authorised.
Conclusion
As technology continues to evolve, the usage and development of smart contracts will become more commonplace, providing businesses with more efficient methods of operating. Smart contracts not only have the potential to save time and money, but they also offer increased security and transparency, making your business overall smarter.
"A smart contract is not just a tool of convenience, it's a necessary evolution in the digital world."

Now that you have your team assembled, it's time to start developing your product. One of the most effective methodologies for SaaS product development is Agile. Let's explore what Agile is and how it can help you deliver a high-quality product efficiently.
If you are wondering “What is Agile?” or “What are these sprints?”, Agile is a development methodology emphasizing flexibility, collaboration, and customer-centricity. Unlike traditional waterfall models that follow a linear path, Agile breaks down the development process into iterative cycles called sprints. Each sprint is a short, time-boxed period where a specific set of tasks is completed, reviewed, and improved upon based on feedback.
Planning and executing sprints are the heart of Agile development, as they enable your team to deliver small, incremental improvements to your product consistently. This iterative process ensures that you're continually refining and enhancing your SaaS product based on user feedback and evolving requirements. By focusing on short, manageable periods of work, sprints help maintain momentum and keep the team aligned with the project's goal.
Planning Your Sprints
Set Clear Goal
Begin by defining what you aim to achieve in each sprint. For example, to create a customizable task dashboard that allows users to filter and sort tasks based on various criteria.
Create a Backlog
The product backlog is a prioritized list of tasks and features that need to be completed. For the dashboard feature, your backlog might include items like designing the dashboard UI, implementing the filter functionality, creating sorting options, and testing the feature.
Sprint Planning Meeting
Hold a sprint planning meeting at the start of each sprint. During this meeting, the team selects items from the backlog to work on. For our dashboard example, the sprint backlog might include designing the UI and implementing the filter functionality.
Define Tasks
Break down each backlog item into smaller, manageable tasks. For designing the dashboard UI, tasks could include creating wireframes, developing the front-end interface, and integrating with existing back-end services. Assign these tasks to team members based on their skills and availability.
Estimate Effort
Estimate the effort required for each task. Use techniques like story points or time estimates. For instance, creating wireframes might be estimated at 5 story points, while integrating the front-end interface could be 8 story points. Accurate estimations help in setting realistic goals and timelines for the sprint.
Executing Your Sprints
Daily Standups
Hold short, daily standup meetings where team members discuss what they worked on the previous day, what they plan to do today, and any obstacles they’re facing. Slack is a useful tool for facilitating these quick, real-time updates and discussions.
Focus on Collaboration
Encourage open communication and collaboration among team members. Agile thrives on teamwork, so create an environment where everyone feels comfortable sharing ideas and asking for help. For example, the front-end developer and back-end developer might need to collaborate closely to ensure smooth integration.
Track Progress
Use tools like Jira, Trello, or Asana to track the progress of tasks. Visualizing progress helps the team stay focused and identify bottlenecks. Regularly update the status of tasks to reflect their current state. In our example, the UI design task might move from “In Progress” to “Review” as it’s completed and needs feedback.
Stay Flexible
Be prepared to adjust priorities and tasks as needed. If new information or feedback comes in, discuss it with the team and decide if changes to the sprint plan are necessary. For instance, if user feedback suggests additional filter options, decide whether to include them in the current sprint or plan for them in the next one.
End-of-Sprint Review
At the end of each sprint, hold a review meeting to showcase the completed work to stakeholders. This provides an opportunity for feedback and ensures the product is on the right track. Demonstrate the new task dashboard, highlighting the filter functionality and design.
Sprint Retrospective
Conduct a sprint retrospective to reflect on what went well, what didn’t, and how processes can be improved. This meeting helps the team continuously improve and avoid repeating mistakes. Discuss any challenges faced during the sprint and identify ways to streamline the process for future features.
By effectively planning and executing sprints, and using the right tools, you can ensure that your SaaS product development is flexible and responsive to user needs. This approach helps deliver a high-quality product that evolves with the market and customer feedback.
Serverless queues are a powerful tool for handling tasks like e-commerce orders or asynchronous communication. But if you're processing credit card data, PCI compliance is non-negotiable. Here's what you need to know:
Encryption is key: Use strong encryption (e.g., AES-128 or higher) for data at rest and in transit. Tools like AWS KMS or Azure Key Vault can help.
Access control matters: Limit permissions with role-based access control (RBAC) and enforce multi-factor authentication (MFA).
Monitoring is essential: Log all activities (e.g., AWS CloudTrail, Azure Monitor) and review logs regularly to catch issues early.
Cloud providers share responsibility: Platforms like AWS, Azure, and GCP simplify compliance but require you to secure your applications.
Quick PCI Compliance Checklist for Serverless Queues:
Encrypt sensitive data.
Use tokenization to reduce risks.
Limit access with IAM roles and MFA.
Monitor and log system activities.
Conduct regular audits and tests.
By following these steps, you can leverage serverless queues while protecting sensitive payment data and staying PCI-compliant. Dive into the article for specific implementation examples on AWS, Azure, and GCP.
How to Handle Card Data with Serverless and AWS - PCI Regulations
Building PCI-Compliant Serverless Queues
This section dives into the technical steps needed to secure serverless queues while adhering to PCI compliance standards. To protect cardholder data and ensure scalability, it's crucial to implement layered security measures, focusing on encryption, access management, and continuous monitoring.
Encryption and Tokenization Methods
Encryption plays a critical role in meeting PCI compliance requirements. According to PCI DSS 4.0.1, handling Sensitive Authentication Data (SAD) requires the use of robust encryption algorithms. Use strong encryption methods, such as AES with keys of 128 bits or higher, to secure data both at rest and in transit. Additionally, encryption keys should be stored separately and protected with strict access controls.
Christopher Strand, an expert in compliance, highlighted the importance of these changes:
"PCI will state that 4.0 is the biggest change to PCI in a long time. It's one of the biggest releases of the standard in a while."
Another essential tool in securing sensitive data is tokenization. Unlike truncation, which removes parts of the data, tokenization replaces sensitive cardholder information with non-sensitive tokens that have no mathematical link to the original data. This method significantly reduces the risk of exposure. Effective key management is also crucial - this includes practices like regular key rotation and maintaining detailed audit trails. PCI DSS 4.0.1 emphasizes that storing Sensitive Authentication Data should only occur when there's a documented and legitimate business need.
Once data is encrypted and tokenized, the next step is to control access to these queues.
Access Control and Role Management
Securing data is only part of the equation; restricting access is equally important for maintaining PCI compliance. Role-based access control (RBAC) is a key strategy, ensuring that each user or system only has the permissions necessary for their role. To further enhance security, implement multi-factor authentication (MFA) and enforce strong password policies.
Cloud platforms provide tools to simplify and strengthen access control. For example:
Restricting IAM roles for Lambda functions: Minimizes exposure by granting only the permissions needed for specific tasks.
AWS IAM Identity Center: Streamlines user access management across multiple accounts.
Regular reviews are essential. Conduct quarterly audits and use automated monitoring tools, such as AWS Config, to ensure that access rights align with current responsibilities and roles.[9, 11, 13, 14]
Monitoring and Logging for Compliance
Once encryption and access controls are in place, monitoring and logging become the final pieces of a compliant strategy. PCI DSS Requirement 10 mandates tracking and monitoring all access to network resources and cardholder data. The updated standard emphasizes the need for automated log review mechanisms.[17, 16]
Robert Gormisky, Information Security Lead at Forage, explains the importance of automation in this process:
"You really want to increase the frequency on which you're doing some of these activities. What that means from a technology perspective is that you're going to want to look for tools that allow you to automate things more and more."
A robust logging system should capture critical events, including:
Access to cardholder data
Administrative actions
Attempts to access audit trails
Invalid access attempts
Changes to authentication mechanisms
Each log entry should include details like the event type, timestamp, outcome, origin, and affected components. Services like AWS CloudTrail, CloudWatch, and AWS Security Hub provide detailed logs, real-time monitoring, and centralized dashboards to simplify compliance efforts.
To meet PCI guidelines, retain log data for at least one year, with the last three months readily accessible. Synchronize system clocks to ensure accurate event correlation, and protect log data with measures that preserve its integrity and restrict access. Daily log reviews, guided by risk analysis, are essential for detecting potential security incidents early.[15, 16, 17]
Technical Implementation Examples
Here’s how you can implement PCI-compliant serverless queues on major cloud platforms, using encryption, access controls, and network configurations tailored to meet compliance standards.
AWS Simple Queue Service (SQS) supports server-side encryption options designed to meet PCI compliance requirements. You can opt for either SQS-managed encryption keys (SSE-SQS) or AWS Key Management Service keys (SSE-KMS). The latter gives you greater control over how your encryption keys are managed.
For example, an AWS Lambda function can send encrypted messages to an SQS queue whenever an S3 bucket is updated. Another Lambda function can then decrypt the messages and update a DynamoDB table. To ensure secure communication, all requests to encrypted queues must use HTTPS with Signature Version 4. Additionally, apply the principle of least privilege through IAM policies and regularly rotate access keys. AWS's PCI DSS Level 1 certification provides further assurance of compliance measures.
This setup showcases how AWS-specific features help align with PCI standards.
Azure Service Bus Premium offers encryption capabilities through its integration with Azure Key Vault. Using customer-managed keys (CMK), you can encrypt data, though this feature is limited to new or empty Service Bus Premium namespaces. For effective key management, configure the associated Key Vault with critical settings like Soft Delete and Do Not Purge.
Here’s an example: A test client triggers an HTTP function that encrypts messages using an RSA key from Key Vault. These messages are sent to a Service Bus topic, where another function decrypts and routes them to a queue. Both system-assigned and user-assigned managed identities can securely access Key Vault, and role-based access control (RBAC) ensures a high level of security. While Shared Access Signatures (SAS) are supported, Azure AD authentication is recommended for better control and auditing. Since Service Bus instances periodically poll encryption keys, you’ll need to configure access policies for both primary and secondary namespaces. Grant the managed identity permissions like get, wrapKey, unwrapKey, and list to ensure smooth operations.
This implementation highlights how Azure's tools can meet PCI compliance standards.
Google Cloud Pub/Sub, paired with VPC Service Controls, can create a secure, PCI-compliant serverless queue by establishing strict security perimeters that isolate resources and block unauthorized access.
To implement this, define service perimeters to isolate Google Cloud resources and VPC networks. These perimeters can also extend to on-premises environments through authorized VPNs or Cloud Interconnect connections. Using a restricted virtual IP range with the DNS server (restricted.googleapis.com) ensures that DNS resolution stays internal, adding another layer of security. VPC Service Controls can be run in dry-run mode to monitor traffic without disrupting services, while Access Context Manager allows fine-grained, attribute-based access control. Keep in mind that while VPC Service Controls safeguard resource perimeters, they don’t manage metadata movement. Therefore, continue leveraging Identity and Access Management (IAM) for detailed access control.
This example demonstrates how Google Cloud’s ecosystem can support PCI compliance.
Each of these platforms offers a robust approach to building PCI-compliant serverless queues, giving you the flexibility to choose the best fit for your infrastructure and compliance needs.

Maintaining Continuous Compliance
In dynamic serverless environments, maintaining PCI compliance requires constant vigilance and monitoring.
Automated Compliance Monitoring
Automated tools play a critical role in continuously scanning your environment and flagging compliance violations.
AWS Config is a valuable tool for real-time monitoring of AWS resources and their configurations. It allows you to set up custom rules to ensure your SQS queues meet encryption and access control standards. Any configuration changes that violate PCI requirements are flagged immediately.
Prisma Cloud specializes in compliance checks tailored for serverless functions. With advanced scanning capabilities developed by Prisma Cloud Labs, it identifies risks such as overly permissive access to AWS services, sensitive data in environment variables, embedded private keys, and suspicious behaviors that could jeopardize PCI compliance.
Cloud Custodian serves as a policy-as-code solution to enforce compliance across your cloud infrastructure. It allows you to write policies that can automatically remediate non-compliant resources, such as deleting unencrypted queues or tightening overly broad IAM permissions.
Infrastructure-as-code (IaC) tools also play a vital role in maintaining consistent security configurations for serverless queue deployments. These tools detect unauthorized changes in real time and can automatically revert configurations that fail to meet PCI standards. Regularly updating cloud security policies ensures they align with the latest PCI DSS requirements and address emerging threats in serverless environments.
While automation is essential, independent audits provide an additional layer of validation for your compliance efforts.
Third-Party Assessments and Audits
Third-party audits are crucial for validating your PCI compliance and uncovering gaps that internal monitoring might overlook.
"Compliance is not security. But compliance is the vehicle with which we can delve deeper into various parts of your security program and find out where is the security level." – Jen Stone, Principal Security Analyst, SecurityMetrics
To prepare for audits, align penetration tests with your audit schedule. These tests should focus on risks specific to serverless environments, such as overly permissive IAM roles, exposed storage buckets, and insecure APIs.
Separating PCI and non-PCI data into distinct cloud accounts simplifies audits. This approach reduces the scope of environments handling cardholder data, making audits more manageable and focused.
Maintain detailed documentation that maps your serverless queue architecture to the 12 PCI DSS requirements. Clearly define shared responsibilities with your cloud service provider and automate compliance reporting using tools for asset inventory and gap analysis. Your provider should supply PCI DSS Level 1 compliance reports and relevant documentation to support your audit preparations.
Involve engineers, infrastructure teams, and product managers in your audit preparations. This collaborative effort ensures every aspect of your serverless queue implementation is ready for assessment.
Incident Response and Recovery Planning
Even with robust monitoring and audits, a well-prepared incident response plan is essential for minimizing damage during a breach.
An effective incident response plan ensures swift action to reduce the impact of a breach and restore operations quickly. Your plan should include workflows that trigger automatic responses to security alerts. For instance, if a potential compromise is detected in your serverless queue environment, the response should immediately capture forensic evidence before initiating remediation actions.
Automate forensic evidence capture by taking snapshots or backups of compromised resources before replacing them. This preserves critical evidence for investigations while allowing services to continue running. For example, you could capture snapshots of affected functions and store essential configurations to enable rapid recovery.
Ensure all recovery steps include validation to confirm that replacement resources meet PCI compliance standards. Test security controls and access permissions before bringing systems back online. Additionally, establish procedures to securely decommission compromised resources to prevent data leaks or unauthorized access.
Your incident response plan should prioritize minimizing downtime for customer-facing services while isolating affected assets for investigation. Automated recovery workflows can help maintain service availability during incidents while preserving your compliance posture.
Regularly test and update your incident response procedures to keep them effective as your serverless architecture evolves. Document lessons learned from each incident to refine your response strategies and strengthen your compliance efforts over time.
Conclusion: Best Practices and Key Points
Creating PCI-compliant serverless queues requires careful attention to encryption, strict access controls, and ongoing monitoring. These elements form the backbone of a secure system that meets regulatory standards while maintaining the flexibility and efficiency of serverless architecture.
Key Points for PCI-Compliant Queues
Encryption: Protect data both at rest and in transit using robust encryption techniques and reliable key management tools like AWS KMS or Azure Key Vault.
Access Control: Enforce the principle of least privilege with detailed IAM roles and policies. Consider deploying functions within a VPC to minimize exposure.
Monitoring and Logging: Use tools like CloudWatch and CloudTrail for detailed logging and conduct frequent audits to identify and address potential security issues promptly.
By following these practices, organizations can secure their current operations while preparing for future challenges.
Future Trends in Serverless and PCI Compliance
The world of serverless security and PCI compliance is rapidly changing as new technologies and threats emerge, reshaping the way organizations approach security.
Post-Quantum Cryptography (PQC): With quantum computing expected to render current encryption methods like RSA and ECC obsolete by 2030, it’s vital to start adopting post-quantum cryptographic algorithms now. Transitioning to these new methods will be a gradual process, but early preparation is key.
"Quantum computing technology could become a force for solving many of society's most intractable problems, and the new standards represent NIST's commitment to ensuring it will not simultaneously disrupt our security." – Laurie E. Locascio, Under Secretary of Commerce for Standards and Technology and NIST Director
Zero Trust Security: The Zero Trust model, which requires verification for every access attempt regardless of location, is becoming essential for securing distributed serverless systems. By 2025, 75% of enterprises are expected to adopt Zero Trust frameworks.
AI and Machine Learning Integration: AI-powered tools are making compliance monitoring more efficient by detecting violations in real time, easing the workload for security teams.
Multi-Cloud Strategies: To avoid vendor lock-in and improve resilience, more organizations are embracing multi-cloud approaches.
With the cost of data breaches projected to hit $6 trillion annually by 2025, the importance of designing adaptable and forward-thinking security measures cannot be overstated. By leveraging automated tools and maintaining vigilant monitoring, businesses can ensure their serverless queue systems stay secure and compliant with evolving PCI standards and emerging security trends.
FAQs
What is the difference between tokenization and encryption, and why does it matter for PCI compliance in serverless queues?
Tokenization and encryption are both effective methods for securing sensitive data, but they operate in fundamentally different ways. Tokenization works by replacing sensitive information - like credit card numbers - with randomly generated tokens that hold no usable value outside a specific system. This approach significantly reduces the amount of sensitive data stored, which in turn simplifies compliance with PCI standards.
Encryption, on the other hand, transforms sensitive data into unreadable ciphertext using an algorithm. The data can only be accessed by decrypting it with the correct key. While encryption provides strong protection, it doesn’t remove the sensitive data from your system, meaning it could still be a target for cyberattacks.
When it comes to PCI compliance, tokenization offers a clear advantage. By using tokens in serverless queue systems, businesses can securely process transactions without directly handling cardholder data. This not only simplifies compliance with PCI DSS but also strengthens security by ensuring that intercepted tokens are useless to would-be attackers.
How can I implement a Zero Trust security model for serverless systems managing payment data?
How to Apply a Zero Trust Security Model to Serverless Systems Handling Payment Data
When managing sensitive payment data within serverless systems, implementing a Zero Trust security model is crucial. Here are the key principles to focus on:
Explicit Verification: Every user and device must be authenticated and authorized based on their identity, device status, and the sensitivity of the data they are accessing. This ensures only legitimate access is granted.
Least-Privilege Access: Permissions should be restricted to the bare minimum required for each role. This reduces the risk of unauthorized access and limits the scope of potential damage.
Assume Breach: Operate under the assumption that breaches are possible. Use segmentation to isolate different parts of your system and encryption to protect sensitive data, minimizing the impact of any security incidents.
Continuous Monitoring: Real-time monitoring and logging are essential to detect and respond to unusual activity quickly. This proactive approach helps mitigate threats before they escalate.
Data Encryption: Always encrypt sensitive payment data, both while it's being transmitted and when it's stored. This extra layer of protection safeguards data from unauthorized access.
By following these principles, you can enhance the security of your serverless systems while ensuring compliance with PCI requirements for handling payment data.
How do tools like AWS Config and Prisma Cloud help ensure PCI compliance in serverless environments?
Automated tools like AWS Config and Prisma Cloud play a key role in ensuring PCI compliance in serverless environments. AWS Config works by keeping a close eye on your serverless resources, continuously checking their configurations against PCI DSS requirements. It comes with pre-built rules that match PCI standards, helping you spot compliance issues quickly and even offering ways to fix them.
On the other hand, Prisma Cloud provides real-time monitoring along with pre-designed compliance frameworks specifically built for PCI DSS. It helps enforce custom policies, ensures serverless functions and their resources stay compliant, and identifies potential risks before they become major problems. When used together, these tools make managing compliance in ever-changing serverless environments much easier while minimizing the chances of falling out of compliance.
