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.
