Assumed Breach Assessment: What Happens When the Attacker Is Already Inside?

The modern security reality is that a breach is inevitable. Perimeter defenses can be bypassed, and a determined attacker will eventually find a way in. The most critical question then becomes: What happens next? Our Assumed Breach Assessment is an intense, practical exercise designed to test your most critical capability: your ability to detect, contain, and eradicate an adversary who is already operating on your internal network.

Who Is This Service For?

This advanced simulation is designed for organizations that need to validate their detection and response capabilities:

  • Incident Response (IR) Teams who need to pressure-test their playbooks, tools, and communication channels in a realistic, controlled scenario.

  • Security Operations Centers (SOCs) that need to measure their ability to detect and triage sophisticated post-exploitation activity.

  • CISOs and Security Leaders who require concrete assurance that their investment in detection technologies (like SIEM and EDR) is providing real value.

Answering the Toughest Questions About Your Response Readiness:

This exercise provides clear, evidence-based answers to the questions that follow an initial compromise:

  • How long would a skilled attacker go undetected on our network?

  • Are our detection tools and security analysts tuned to spot lateral movement and privilege escalation?

  • Do our incident response playbooks actually work under the pressure of a live event?

  • Can we effectively contain a breach and prevent an attacker from reaching our crown jewels?

Our Methodology: A Collaborative Test of Resilience

Unlike a traditional penetration test, an Assumed Breach exercise is not about finding a way in. We begin with the premise that we are already inside.

  1. Scenario Definition: We work with you to define the starting point. This could be compromised user credentials, a shell on a standard employee workstation, or access to a cloud server.

  2. Controlled Post-Exploitation: Our experts, mimicking the TTPs (Tactics, Techniques, and Procedures) of a real adversary, will attempt to escalate privileges, move laterally across the network, and locate sensitive data.

  3. "Purple Team" Collaboration: This is a highly collaborative exercise. We work in close coordination with your defensive team (the "Blue Team"). The goal is not simply to "win," but to test, measure, and improve their detection and response capabilities at every step.

  4. Immediate Feedback Loop: When we execute an attack technique, we observe your team's response. Did they see it? How long did it take? Was the alert actionable? This provides an invaluable, real-time training opportunity.

Your Deliverables: A Play-by-Play Guide to Improving Your Defenses

The outcome is a detailed analysis of your true response capability:

  • Executive Summary: A high-level assessment of your organization's ability to handle a post-compromise scenario, highlighting key strengths and critical gaps.

  • Attack Path Timeline: A detailed, chronological narrative of every action we took, providing a clear story of the simulated breach.

  • Detection & Response Scorecard: A clear report card showing which attacker techniques were detected, which were missed, and the mean-time-to-detection for each successful alert.

  • Actionable Tuning and Playbook Recommendations: Specific, practical guidance for tuning your security tools, writing new detection rules, and refining your incident response procedures to address the identified weaknesses.
