Breach and Attack Simulation (BAS) for Security Control Validation

Once security products are deployed, they are often assumed to be working. Yet a policy change, an agent update or a broken log source can silently render a control ineffective.

BAS turns that assumption into measurable fact by showing which techniques are blocked, which are only logged and which go unseen.

MITRE ATT&CK is a publicly available knowledge base that classifies adversary tactics and techniques observed in real-world attacks. Mapping our scenarios to it lets us report results in a language the industry shares.

• Endpoint protection (EDR/antivirus): whether emulated malicious behavior is blocked
• SIEM and SOC: whether relevant events are logged and raise alerts
• Email gateway: whether test messages with malicious attachments and links are filtered
• Web proxy and DNS security: whether connections to malicious domains and command-and-control traffic are stopped
• Network segmentation and data exfiltration controls

1. Objectives and scope: we select a scenario set based on threat groups relevant to you and your critical controls.
2. Preparation: we agree on representative systems for the simulation and plan communication with your SOC.
3. Execution: scenarios run in a controlled manner; no real malware is used and no persistent changes are left on your systems.
4. Analysis: each technique is marked as blocked, detected or missed on the ATT&CK matrix.
5. Improvement and retest: we recommend rule and policy changes, then rerun the same scenarios after fixes to measure progress.

• A prevention and detection coverage map on the ATT&CK matrix
• A gap list per control with concrete configuration and rule recommendations
• Period-over-period comparison showing how your security posture changes

Red teaming is a covert, objective-driven attack carried out end to end by a human team. BAS focuses on testing specific techniques frequently and repeatably; BAS scenarios can also serve as a shared starting point in purple team exercises.
