Penetration Testing
Manual, evidence-led testing that finds the holes attackers would, before they do.
We test web and mobile applications, APIs, networks, cloud and Active Directory using a structured methodology aligned to the OWASP Testing Guide and the Penetration Testing Execution Standard. Findings are mapped to MITRE ATT&CK and delivered with reproducible proof of concept, so your engineers can replicate, verify and fix each issue. We test our own platforms the same way, including NUEXUS Defender.
Included in this service
Web, mobile and API testing
Manual testing of applications, APIs and authentication flows, beyond what automated scanners surface.
Internal and external network testing
External perimeter and internal network paths, including Active Directory and lateral movement.
Reproducible proof of concept
Each finding includes the exact request, response and payload so you can reproduce it.
Prioritised remediation
Risk rated by impact and likelihood, with fixes ordered so you tackle the right things first.
What you walk away with
- Penetration test report with reproducible proof of concept per finding
- Risk-rated findings mapped to MITRE ATT&CK and CVSS
- Prioritised remediation plan for engineering
- Free retest and closure confirmation for fixed issues
- Detection and logging recommendations
- Security hardening checklist
A clear path from problem to outcome
Scope and rules of engagement
We agree targets, objectives and constraints in writing: in-scope assets, test windows, success criteria and emergency stop conditions. You get a signed authorisation and a named point of contact before any tooling touches your environment.
Execute and validate
Our team runs the engagement against agreed objectives, whether that is exploitation, detection validation or a build. Activity is mapped to MITRE ATT&CK where relevant, and we confirm each finding so you receive evidence, not noise.
Report with reproducible proof
Every finding ships with a reproducible proof of concept: request and response, payloads, screenshots and exact steps. Risk is rated by business impact and likelihood, with clear, prioritised remediation guidance your engineers can act on.
Remediate and retest
We walk your team through fixes, answer questions and retest to confirm closure. You finish with a clean retest record and, where useful, detections and runbooks so the same gap is caught next time.
