Prevent, Detect, Respond: A MITRE-Driven Guide to Breach Mitigation

In today’s rapidly evolving cyber threat landscape, UK businesses face relentless pressure to defend against increasingly sophisticated attacks. With high-profile breaches making headlines and compliance demands tightening under regulations like GDPR and the NIS2 Directive, the need for a structured, proactive security posture has never been greater.

This is where the MITRE ATT&CK framework proves invaluable. By mapping out adversarial tactics and techniques used in real-world breaches, MITRE helps organisations move from reactive fire-fighting to intelligence-led, proactive security strategies.

At ANSecurity, we integrate this framework into our cyber defence methodology, helping UK organisations prevent, detect, and respond to threats with precision and confidence.

Prevent: Shutting the Door Before Attackers Enter

MITRE-aligned prevention begins with understanding how adversaries operate. ANSecurity helps organisations map potential attack paths based on their infrastructure and industry profile. This insight allows us to harden defences in a focused, efficient way.

ANSecurity’s prevention services include:

• Zero Trust Architecture deployment to limit lateral movement

• Micro-segmentation of networks to reduce attack surfaces

• Secure access solutions using identity-based policies

• Patch and vulnerability management aligned with MITRE techniques

• Security awareness training that links human behaviour to specific tactics

Our team works closely with security and IT stakeholders to ensure that defensive controls not only comply with regulatory requirements, but also align directly with real-world threat behaviours.

Detect: See the Threats Others Miss

Traditional perimeter-based security often fails to spot modern attacks that use legitimate tools and insider pathways. MITRE’s tactics—like Credential Dumping, Lateral Movement, and Data Exfiltration—require advanced detection capabilities.

ANSecurity detection services include:

• SIEM and XDR solutions configured against MITRE ATT&CK techniques

• Threat hunting operations that trace known attack chains

• Behavioural analytics that identify anomalies mapped to MITRE indicators

• Managed Detection & Response (MDR) with 24/7 UK-based SOC support

Using MITRE as a detection map, we help clients distinguish between noise and true indicators of compromise, significantly reducing dwell time and enhancing visibility across hybrid environments.

Respond: Act Fast, Act Smart

Response is often where breaches are won or lost. A slow or misaligned response can turn a minor incident into a major breach. By aligning incident response protocols with MITRE’s known adversarial techniques, we help organisations act swiftly and decisively.

ANSecurity response services include:

• Incident Response Planning with MITRE-informed playbooks

• Breach simulation and tabletop exercises to test readiness

• Digital Forensics and root-cause analysis

• Post-incident remediation aligned to prevent recurrence

• Automated SOAR workflows for real-time containment

We ensure that your response strategy isn’t just compliant—it’s battle-tested and grounded in what real attackers actually do.
