Our Penetration Testing Methodology
To ensure a thorough review, we follow a multi-phase approach aligned with OWASP and NIST standards:
- The process of reconnaissance and scoping requires us to identify assets while we collect intelligence about our target.
- Vulnerability scanning: the process uses automated tools for identifying existing security weaknesses.
- Exploitation (manual testing): the testers try to enter the system to measure the actual security risk that exists from unpatched vulnerabilities.
- The team provides an executive summary with technical instructions that enable developers to correct the software defects.
- The client tests that their implemented patches work as intended.
