Practice · Offensive Security
The pressure test.
OSCP-led, MITRE-aligned.
Penetration testing, red team simulation, phishing campaigns — done by the same senior team that runs your defensive operations. Findings become permanent detections. The MSSP layer learns from the OffSec layer every quarter.

Real exploitation.
Real chains. Real remediation.
OSCP-led. Hands-on offensive certification, not paper-only credentials. The senior on your engagement is the one writing the report.
Manual exploitation. Vendor scanners find low-hanging fruit. Real pentests chain four medium findings into one critical. We do the latter.
MITRE ATT&CK-aligned reporting. Every finding mapped to a technique. Every remediation tied to a detection. Findings convert to permanent detection rules in the MSSP layer.
Free retest included.We come back after remediation, retest at no cost, sign off when it’s closed. Most pentest firms charge a second engagement for verification.
Court-admissible reporting. Hash-verified evidence chain, FRE 901/902-aligned, ready for litigation if the engagement turns into one.
