[01] About
Cybersecurity company specializing in penetration testing and security audits; 16 employees with 16% YoY growth; founded 2007; based in Berlin, Germany; offers black-box, white-box, and code audit services, with notable clients like NordVPN and ExpressVPN.
Cure53 offers classic black-box penetration tests (zero-knowledge) as well as white-box tests and code audits. Web application and mobile app developers speak many languages and so do we. From classic languages as PHP, JavaScript, ActionScript, Java, Ruby, Python and Perl to more exotic candidates like web back-ends written in C++ and Delphi – we've seen them.
Since Cure53 was founded in 2007, we have performed several hundreds of penetration tests against all kinds of web applications, online services, hardware interfaces, mobile applications, libraries and crypto tools. We value manual and thorough tests, human interaction and communication and a short yet to-the-point penetration test report without overhead or pie charts no one wants to see.
