You invested in security.
Does it actually work?
Security Control Validation tests whether your tools detect and block what they should. Real attack simulations, mapped to MITRE ATT&CK, with a clear gap analysis.
What is Security Control Validation?
You have invested in firewalls, EDR, SIEM and other security measures. But do they work? Security Control Validation tests continuously whether your security tools actually detect and block what they are supposed to detect and block. Breach and Attack Simulation (BAS) combined with expert manual validation, mapped to MITRE ATT&CK, with clear blind spot analysis and prioritised remediation actions.
Prove your defences work, not just on paper
The team simulates realistic attack techniques in your production environment and measures whether your security stack catches them. Not a theoretical test, but practical proof that your defences work, or a clear picture of where they do not.
Results are mapped to MITRE ATT&CK so you see exactly which techniques are detected, which are blocked and where your blind spots are. Those blind spots translate directly into concrete actions: add a detection rule, adjust a configuration, extend a tool.
Security Control Validation is not a one-off exercise. The threat landscape changes, your environment changes, attackers adapt their techniques. Periodic validation keeps your defences sharp and your MITRE ATT&CK coverage current.
Security tools that look good on paper
Most organisations assume their security tools work because they are configured and running. That assumption is often wrong.
- Security tools drift from their intended configuration over time. Updates, exceptions, and rule changes silently create gaps. Without validation, you do not know what you are missing.
- Compliance checklists confirm that controls exist, not that they work. A firewall rule on paper and a firewall rule that actually blocks the traffic are two different things.
- New attacker techniques emerge constantly. A detection rule effective against last year's ransomware may not catch this year's variant. Controls need to be validated against current threats, not historical ones.
What is validated
How DEFION conducts Security Control Validation
Baseline inventory
Inventory of security controls and their expected detection and blocking behaviour per MITRE ATT&CK technique.
Attack simulation
Execution of realistic attack techniques mapped to MITRE ATT&CK in your production environment.
Detection and prevention measurement
Establishing which techniques are detected, blocked or missed by each control.
Gap analysis
Identification of blind spots, their risk and their relationship to your threat profile and sector.
Remediation and retest
Implementation of improvements and validation that the gaps are closed. Trend reporting over time.
Deliverables
- MITRE ATT&CK heatmap with detection and prevention coverage
- Per control: effectiveness assessment with evidence
- Gap analysis with prioritised remediation actions
- Remediation advice per blind spot with configuration guidance
- Periodic retests and trend reporting
- Executive summary suitable for CISO and board reporting
Which organisations is this relevant for?
Security Control Validation is relevant for any organisation that has invested in security tooling and wants to know whether that investment is delivering what it promised.
- Organisations that want to know whether their security investment is effective
- SOC teams that want to improve their detection coverage
- Companies that want Purple Team-style validation without a full Red Team engagement
- Organisations with NIS2 or ISO 27001 requirements around control validation
- CISOs who need to demonstrate security effectiveness to the board
Security Control Validation pairs naturally with Managed Threat Detection and Purple Teaming. Validation identifies gaps, Purple Teaming closes them collaboratively, and ongoing detection monitors that they stay closed.
Vendor-agnostic by design
DEFION works with the tooling you already have, or brings ours. No vendor lock-in.
