A security assessment is very difficult to evaluate. However, we do have quite a bit of experience doing penetration tests with other companies, so I know what to expect out of these engagements. They performed so well that they're now set to return for a second project.

Christian Buerger

CEO, Auditi

Berezha Security Group opened our eyes to a lot of things that we weren't even aware of. They came up with a summary of what they were able to achieve and the holes they found in our system in a report that covered our infrastructure and software. They pushed us into taking security a lot more seriously, encouraging us to create a security organization within the engineering department.

Odafe Ojenikoh

Software Engineering Manager, Unifonic Inc

With the help of Berezha, we've diagnosed all pending issues on our production servers and closed 50% within the first week. We felt that Berezha firmly upheld their promises and delivered the test on time, on budget, and with excellent communications. We look forward to working with them more in the future.
