After discussing the scope of the project, a fintech company hired Hacken to identify vulnerabilities in their website. The team conducted a bug bounty program to detect major and minor issues with the site.

Through the bug bounty program, Hacken was able to reveal vulnerabilities that were previously undetected, allowing the client to successfully address them. The team stayed faithful to the guidelines, ensuring a good partnership. They were reliable, focused, and communicative.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

P2PB2B is a next-generation cryptocurrency exchange that is focused on serving its users. The platform was founded in 2018 and since then has become a trusted partner of a number of leading crypto projects. The key distinctive feature of the exchange is the ability to process up to 10,000 trades per second and 1,000,000 TCP connections. The exchange supports more than 200 cryptocurrencies as well as fiat money and this figure is likely to increase in the coming years. The company is focused on ensuring the ultimate protection of user’ data and assets and that is why 95% of cryptocurrencies are stored in cold wallets.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Hacken?

Identification of vulnerabilities via the conduct of a bug bounty program was the main objective for our cooperation. We were interested in detecting such vulnerabilities as remote code execution, server-side request forgery, business logic issues, etc. Apart from detecting major vulnerabilities, we were also interested in identifying even minor bugs that could cause serious business implications.

What were your goals for this project?

Apart from detecting major vulnerabilities, we were also interested in identifying even minor bugs that could cause serious business implications.

SOLUTION

How did you select Hacken?

Although according to the CER rating, we are ranked 12th most Trust Core secure crypto exchanges, we understand that at the time when many leading crypto exchanges experience serious cyberattacks we cannot underestimate the importance of constant strengthening of our resistance to cyber threats. Hacken is a highly reputable brand in the field of cybersecurity consulting whose professionalism is recognized by leading market players. That is why cooperation with Hacken was the most obvious choice for us.

Describe the project in detail.

We conducted a series of strategic calls with the Hacken team to discuss the scope of the project and its details. Hacken specialists clearly articulated the bug bounty program procedure and kept constant contact with us during the program execution.

What was the team composition?

Customer manager and tech team

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Thanks to the bug bounty program on HackenProof Platform, we revealed the vulnerabilities that had not been detected before. As a result, we have successfully addressed the bugs in question before hackers could exploit them to steal users’ assets or private data. The cooperation with the Hacken team has allowed us to sustain our status as one of the most reliable cryptocurrency exchanges in the world.

How effective was the workflow between your team and theirs?

Yes, we are fully satisfied with the cooperation process with Hacken. Hacken specialists strictly obeyed all guidelines and cooperation frameworks developed before the launch of the bug bounty program.

What did you find most impressive about this company?

Reliability, ability to listen to our considerations, and focus on details.

Are there any areas for improvement?

P2PB2B team considers Hacken as a top specialist in the field of cybersecurity and I strongly believe that in the near future this company will only strengthen its status as a highly reputable brand. We are 100% satisfied with the services provided by Hacken.
