Brier & Thorn's Adversarial Emulation service is a penetration testing offering in which security professionals simulate real-world attack techniques to identify exploitable vulnerabilities in a client's systems, applications, and network infrastructure. The service follows the Penetration Testing Execution Standard (PTES) methodology and is structured across six phases: 1. Assessment and Planning – Collaborating with the client to define security needs, risk tolerance, and testing scope. 2. Information Gathering and Reconnaissance – Collecting data on systems, network configurations, and security posture using attacker-mimicking methods. 3. Vulnerability Identification and Exploitation – Applying hacking techniques and tools to uncover vulnerabilities across systems, applications, and network configurations. 4. Post-Exploitation and Privilege Escalation – Attempting to escalate privileges and access critical systems to simulate the impact of a successful breach. 5. Reporting and Recommendations – Delivering a report detailing identified vulnerabilities, their severity, potential impact, and remediation guidance. 6. Post-Test Communication and Support – Providing ongoing communication and guidance throughout the remediation process. Testing scopes are customizable to focus on specific systems, applications, or entire infrastructure based on client requirements. The service is positioned to support compliance with industry regulations and internal security policies.
