Nikhil Sagar’s Confidential Computing Journey at Visa

Securing the Cloud: Visa’s Journey with Confidential Computing

Visa, a pioneer in the financial technology world, is constantly evolving to meet the demands of a rapidly changing digital landscape. One key area of focus for the company has been bolstering its cloud security posture. A key piece of this strategy is the adoption of confidential computing, a groundbreaking technology that is transforming the way data is protected in the cloud.

“Nikhil, thank you for speaking with us today.Could you tell us more about Visa’s journey into the realm of confidential computing? What prompted this shift?”

Visa’s Chief Security Technologist, nikhil sagar, sheds light on the company’s decision to embrace confidential computing. “We’re seeing a significant increase in the amount of sensitive data we process in the cloud,” he explains. “Confidential computing allows us to protect this data even when it’s in use, which is crucial for maintaining customer trust and compliance with evolving regulations.”

But what exactly is confidential computing? Imagine a secure vault within the cloud where your data remains encrypted even as it’s being processed by applications. That’s essentially what confidential computing offers. “Think of it like a secure enclave within your application’s environment,” Sagar illustrates. “The data is encrypted before it enters this enclave,and it remains encrypted throughout the entire processing lifecycle. Only authorized parties with the right keys can decrypt the data, ensuring its confidentiality even in the shared cloud environment.” This approach fundamentally differs from conventional security measures that primarily focus on protecting data at rest or in transit. By encrypting data in use, confidential computing strengthens security at every stage.

Naturally, Visa, known for its operational efficiency and performance standards, was concerned about the impact confidential computing might have on these crucial aspects. Sagar assures us, “We’ve carefully selected confidential computing solutions that are designed to minimize performance overhead.Our testing has shown that the impact on application performance is negligible, allowing us to reap the benefits of enhanced security without sacrificing efficiency.”

Visa isn’t just talking the talk; they’re walking the walk. sagar reveals specific examples of how they are leveraging confidential computing. “We are using it to enhance the security of fraud detection algorithms,” he states. “By protecting sensitive customer data within encrypted enclaves, we can ensure that our fraud models are trained and deployed securely, minimizing the risk of data breaches and protecting customer privacy.”

Looking ahead, Sagar sees confidential computing playing an increasingly crucial role in shaping the cloud security landscape. “It’s a transformative technology that is changing the way we think about data security,” he predicts. “As more organizations adopt cloud-based solutions,confidential computing will become essential for protecting sensitive data and building trust with customers.”

For organizations considering adopting confidential computing, sagar offers a few key considerations.”start by assessing your security needs and identifying the sensitive data that requires the highest level of protection,” he advises. “Then, carefully evaluate different confidential computing solutions and select one that aligns with your technical requirements and business objectives. remember that confidential computing is not a silver bullet. It should be implemented as part of a comprehensive security strategy that includes other measures such as access controls, encryption, and threat monitoring.”

Securing the Cloud: Visa’s Journey with Confidential Computing

Visa, a global leader in the payments industry, understands the critical need for robust security in the cloud. As more financial data moves to the cloud, so too dose the risk of breaches. Recognizing this, Visa is taking a proactive approach with confidential computing, a cutting-edge technology that shields sensitive data even in public cloud environments.

“The key is to create a system that not only secures sensitive data but also maintains high performance and availability,” explains Nikhil sagar, a developer on Visa’s VPA2A team, who is at the forefront of this digital security revolution. This balance between security and operational efficiency is crucial for any association handling sensitive facts like bank account details, credit card numbers, and health records.

Confidential computing, with its secure enclaves and isolated environments, ensures that not even the cloud provider can access the data. This is a game-changer for industries like finance, where protecting user information is paramount. Visa is utilizing this technology through AWS Nitro Enclaves to develop secure and tamper-proof environments for deploying sensitive applications.

Nikhil’s team undertook a project to develop a highly available Tier-0 submission using a DIY approach with AWS Nitro Enclaves. This journey involved meticulous design and growth to achieve the delicate balance between security and performance. “The process involved addressing specific requirements and challenges unique to our use case,” Nikhil explains, “ensuring that the system could handle sensitive data securely while maintaining the high-performance standards expected of Visa’s operations.”

This successful project highlights Visa’s commitment to innovation and technical expertise in tackling complex cloud security challenges. Their experience with AWS Nitro Enclaves showcases the power of confidential computing to secure sensitive workloads and adapt to various business needs.By embracing this technology, Visa is setting a precedent for other organizations looking to confidently migrate their operations to the public cloud, knowing that their data is protected.

Looking ahead, Nikhil Sagar’s insights underscore the importance of proactive security measures in the ever-evolving world of cloud computing. “By embracing advanced technologies like AWS Nitro Enclaves,” Nikhil says, “companies can confidently migrate to public cloud platforms, ensuring the protection of their sensitive data and the continuous success of their operations.”
