We approached Sakurity to audit our existing platform, and perform ongoing reviews of upcoming products. Sakurity have a proven and well-regarded understanding of web application security, and were able to identify and help us fix several key vulnerabilities, making our platform significantly more secure.

Egor and the Sakurity team were a pleasure to work with, both during the process of an issue they reported to us and for an assessment they performed on contract. Their efforts have helped us further harden the security of our two-factor authentication platform.

As a payments company, security is core to everything Stripe does. I've worked with Sakurity both through their responsible disclosures as well as a contracted penetration test of Stripe. Sakurity has always been professional and responsible in their work, and Stripe today is more secure due to their efforts.
