Penetration Testing

Our Intelligence-led Penetration Testing assessment is the practice of attacking a problem from an adversarial point of view and follows a different approach from a typical security assessment. It relies heavily on well-defined tactics, techniques, and procedures (TTPs), which are of utmost importance to successfully emulates a realistic threat or adversary.

Penetration Testing

Penetration Test helps organizations identify and remediate exploitable security vulnerabilities before attackers can take advantage of them. Every assessment is performed manually by OSCP-certified engineers using industry-recognized methodologies including OWASP Testing Guide and SANS/CWE frameworks, going beyond automated vulnerability scanning to uncover real-world attack paths. The final report includes: detailed technical findings, proof of exploitation, reproduction steps, supporting evidence, CVSS severity ratings, business impact, and prioritized remediation recommendations. Each report is signed by the OSCP-certified engineer who performed the assessment. The deliverables are designed to support security and compliance initiatives, including SOC 2, ISO 27001, and HIPAA, and include an auditor-ready penetration testing report, an attestation letter, and an executive summary. Every engagement also includes a complimentary remediation retest.
