PLEX Solutions provides adversarial simulation and penetration testing services using NSA NSCAP-accredited cybersecurity assessment methodology. The company specializes in offensive security testing to identify security flaws in applications and gain remote access to networks without requiring source code access or extensive internal network knowledge. The service offerings include internal penetration testing to assess what an attacker could accomplish after compromising an internal workstation, and external penetration testing to validate perimeter hardening efforts and identify exploitable vulnerabilities. Both testing types focus on finding commonly overlooked security configuration flaws and known security bug classes. Red team assessments are available for organizations with mature security programs seeking to test their defenses and incident response procedures against simulated advanced persistent threat attacks. These assessments emulate determined attackers using various mechanisms to breach organizations and access sensitive data. PLEX holds NSA NSCAP VAS accreditation, which evaluates providers across 16 vulnerability assessment functional areas including service delivery capabilities, staff skill development, and ability to keep pace with advanced threat actors through training and situational awareness.
