Assumed Breach Assessments
Why it matters
Assumed Breach Assessments start from the premise that an attacker already has a foothold inside your environment. Instead of testing perimeter defenses, the assessment focuses on what an attacker can do after initial access and how effectively your organization can detect, contain, and respond to internal threats.
This approach reflects the reality of modern breaches, where attackers often bypass preventive controls and operate using valid credentials. The goal is to understand how quickly abnormal activity is identified, how far an attacker can move, and whether meaningful impact can be achieved before response actions are taken.
What We Test
Post-compromise attacker activity within internal environments
Credential abuse, privilege escalation, and access expansion
Lateral movement across endpoints, servers, and network segments
Abuse of trust relationships, service accounts, and misconfigurations
Detection and response effectiveness of SOC and security tooling
Incident response workflows and escalation processes
Our Differentiated Approach
We evaluate how well your organization handles a breach in progress, not how strong the perimeter appears on paper.
Starting from realistic compromise scenarios rather than external entry point
Focus on identity-centric attack paths common in real breaches
- Low-noise techniques to validate true detection and response capability
Clear measurement of containment speed and response effectiveness
How We Deliver
Breach Scenario Definition
We agree on realistic breach assumptions such as compromised user credentials, a malicious insider scenario, or a compromised endpoint, aligned to your threat model.
Internal Attack Path Design
Attack paths are designed to simulate how attackers escalate privileges, move laterally, and pursue high-value targets within the environment.
Controlled Post-Breach Activity
Our team executes attacker behavior using stealthy techniques to test detection, response, and containment without disrupting business operations.
Detection & Containment Evaluation
We assess which activities were detected, how quickly alerts were generated, and how effectively teams contained the simulated breach.
Reporting & Remediation Guidance
We deliver a clear breach narrative with prioritized recommendations focused on improving post-compromise resilience.
Key Deliverables
Breach scenario narrative and attacker timeline
Detection, response, and containment gap analysis
Technical findings with supporting evidence
Identity, logging, and monitoring improvement recommendations
Optional Purple Team validation exercises
Business Outcomes
Improved visibility into post-breach risks
- Faster detection and containment of internal threats
Stronger identity and privilege management practices
More effective incident response processes
- Increased confidence in breach readiness
Standards & Best Practices
Our assumed breach assessments are informed by:
MITRE ATT&CK post-compromise techniques
Real-world breach investigations and attack patterns
Industry best practices for incident detection and response
Why Assumed Breach Assessments Matter
Perimeter defenses will eventually fail. Assumed Breach Assessments focus on what matters most after that point: limiting attacker movement, reducing impact, and responding decisively before serious damage occurs.
