Frequently Asked Questions

What methodologies do you use?

We base our testing on OWASP Testing Guide, PTES, NIST SP 800-115, and OSSTMM frameworks.

Can we review previous work examples?

Due to NDA constraints we cannot share client names, but we can provide redacted sector-specific case studies and proof summaries.

Do you test remotely or on-site?

Most tests are conducted remotely via VPN. For internal network and physical security tests, we deploy on-site teams.
