Unique Value Proposition
Hackers on your side. Skilled and ethical.

Our team consists of certified professionals with extensive experience in IT security. Whilst CISSP certificate provides team’s broad overview of security, CEH guarantees technical ability of the team to use invasive (meaning: we try to perform the same types of attacks as normal hackers would perform) methods of audit. Both certifications indicate the ability to do ethical hacking, which is carried out through high standards of our company in operation and management of human resources.
