Manual, exploit-driven engagements run by operators who compromise systems for a living. Five services that map your real exposure, prove what is exploitable, and verify every fix.
Identify exploitable vulnerabilities before attackers do.
Learn more 02Simulate real adversaries to test resilience.
Learn more 03Proactively uncover hidden threats.
Learn more 04Discover exposed assets and intelligence leaks.
Learn more 05Understand what attackers see.
Learn moreFrom first finding to verified fix - the five-step path every assessment follows. Hover a star to expand the step.
Identify weaknesses across your in-scope estate, combining tooling with manual inspection to surface what automated scans miss.
Confirm exploitability by reproducing each issue by hand and proving it with a working attack path, so nothing ships as a false positive.
Assess business impact by ranking findings on real-world exploitability and the sensitivity of what sits behind them, not raw severity alone.
Fix before exploitation with concrete, engineer-ready guidance, and support your team directly through the changes where it helps.
Retest and secure by re-attacking remediated findings to confirm they are genuinely closed and no new exposure was introduced.

We build on established frameworks and treat them as a coverage floor, not a checklist.
The open standard for application and API security testing.
We test web and API targets against the OWASP Testing Guide and the Top 10 risk categories, treating them as a coverage floor rather than a checklist. The OWASP Application Security Verification Standard gives our reports a shared, measurable baseline that maps cleanly to your developers' frame of reference. For APIs, we work to the OWASP API Security Top 10, which captures the authorization and exposure risks unique to that surface.
The shared taxonomy of real-world adversary tactics and techniques.
Every red-team action and hunting hypothesis is mapped to MITRE ATT&CK, so results are expressed in the same language your detection engineering and threat intelligence teams already use. We emulate the specific techniques associated with the threat groups relevant to your sector, then measure your detection coverage technique by technique. The matrix becomes a scorecard: a precise map of which adversary behaviors you can see and which you cannot.
Federal guidance for risk-based security testing and assessment.
We align technical testing with NIST SP 800-115, the standard methodology for security testing and assessment, and frame results against the NIST Cybersecurity Framework so leadership can read them in risk terms. This makes our findings straightforward to slot into existing governance, audit, and risk-management processes. Where relevant, we reference the SP 800-53 control families that a finding implicates.
The end-to-end standard for how a penetration test is run.
The Penetration Testing Execution Standard defines the lifecycle our engagements follow, from pre-engagement scoping through intelligence gathering, threat modeling, exploitation, post-exploitation, and reporting. Following PTES keeps engagements consistent and rigorous regardless of who runs them, and ensures the unglamorous phases - scoping and post-exploitation analysis - get the same discipline as exploitation. It is the connective tissue between the technique-level frameworks and a coherent engagement.
