Our Services
Adversary Simulation

We operate as a true attacker whose goal would be to disrupt your business operations.  When we begin our assessment, your business is a ‘black box’. We are focused on ensuring our evaluation of your detection and response capabilities are as realistic as they can be. At the outset, we develop rules of engagement with you to identify high value targets that could be most problematic if compromised.

Stealth Approach

Assessments with realistic time constraints (e.g., 1-6 months); Simulate attackers who are using current tactics, techniques, and procedures (TTPs) to actively avoid detection and response controls while pursing high value business targets.


Path of Least Resistance

Simulate adversary focused on achieving objectives; not a race to “Domain Admin”. We simulate hackers not just looking for access, but APTs looking for monetary or other business-related advantages to their attacks.

Social Engineering (OSINT)

We deploy complex, layered social engineering campaigns, often bridging across communication mediums (email, phone, etc.) as well as physical boundaries. Focus is placed on abusing weaknesses in business processes with information from public sources.

Adversary Emulation

We emulate selected Tactics, Techniques, and Procedures (TTPs) a sophisticated and patient APT (Advanced Persistent Threat) would use to attack your security infrastructure. We work with your security team to identify TTPs you’d like to focus on. You have the flexibility to focus your assessment on specific areas of your security infrastructure or see how vulnerable your business is to commonly accepted TTPs (e.g. MITRE framework, etc.).

‘Live fire’ collaboration

We conduct the assessment using a Defender and Attacker posture to provide your team with hand-on, real time training and experience. This provides defenders a unique experience and understanding of the attackers tools and techniques.


Highly Controlled Execution

Our emulation is executed on a specific system(s) in a controlled manner. This provides insight into the effectiveness of your control environment.


Dynamic Testing Approach

We execute with real-time profile adjustments throughout the exercise allowing your team to modify defender tactics in real-time. The end results should be a robust control environment and better processes for continuing improvement in detection and response.

Incident Response PLanning

We assess your current IR procedures and organizational posture, and recommend how you can better respond to an incident. We leverage the IR assessment and guide your organization through table-top exercises. We simulate an incident in real time, and guide your IR team how to better detect, mitigate, and respond against an attack.



We provide recommendations to improve your overall response posture, from procedures, policies, chain-of-command execution, and priority decision making.

Table-top exercises

We execute your Incident Response plan with your team; guide them through the procedures; develop clarity in who does what, when, and why.

Live Fire

We walk through executing your IR plan in a controlled sandbox or in a ‘live fire’ setting to test your team and IR plan.
