Project details

I offer professional penetration testing that includes a comprehensive report detailing any vulnerabilities found and recommended fixes based on best practices. The testing is conducted by a highly experienced and certified professional (OSCP, OSEP) with a proven track record of completing over one hundred successful projects. They are also a leader of hacking teams in competitions, regularly keep up-to-date with the latest hacks and exploits, and have worked for top IT companies, consistently delivering exceptional results.

To ensure the best possible results, penetration testing is carried out mainly manually, leaving no stone unturned. Automated scanners are only used upon the client's request as they can be noisy, generate excessive traffic, and produce false positives.
