Penetration Tests

Penetration tests, or regular simulated cyber attacks conducted every 3-6 months are the best way to make sure your software and hardware systems are well secured. We identify potential weakness, provide evidence of the existing vulnerabilities, and study potential of their exploitation by the threat actors. To do so we conduct black, grey and white-box penetration testing of web, mobile, cloud applications and IT infrastructure. We follow such methodologies as OWASP Application Security Verification Standard, OWASP Web Security Testing Guide, OWASP Mobile Security Testing Guide, Penetration Testing Executing Standard.
