Incident Response

At Checkdone IT, we believe that the true measure of cybersecurity strength lies not in preventing every incident — but in how quickly and effectively we respond when things go wrong. Our Incident Response (IR) capability ensures that we can identify, contain and recover from cyber threats with minimal impact on operations, reputation and trust.

Cyber incidents can range from phishing attacks and malware infections to unauthorised access, insider threats or large-scale breaches. No matter the source, our goal is the same: respond fast, contain the risk, and learn from it to improve future resilience.

Structured and Proactive

Our approach is based on a structured, six-phase response model, ensuring consistency, accountability and clarity throughout the incident lifecycle:

1. Preparation – Building playbooks, assigning roles, and ensuring tools, training and communication channels are ready

2. Detection and Analysis – Rapid identification of suspicious activities through monitoring systems, threat intelligence and user reports

3. Containment – Isolating affected systems to limit damage while maintaining continuity

4. Eradication – Removing malicious components and identifying the root cause

5. Recovery – Restoring systems and verifying integrity

6. Lessons Learned – Conducting a detailed review and updating processes and defences

Tools, Forms and Collaboration

We maintain a centralised Incident Register, where each event is logged with full context: source, impact, actions taken, timeline, and resolution. For every incident, we generate a standard set of documentation:

• Incident Intake Form

• Containment and Eradication Checklist

• Post-Incident Review Template

• Evidence Handling Record

All forms are completed by the response team and reviewed during weekly SOC (Security Operations Centre) briefings.

We also integrate our IR process into our broader governance and risk framework. High-impact incidents are escalated and linked to relevant risk entries in our Enterprise Risk Register, ensuring that incident trends inform strategic decisions.

Automation and Intelligence

Where possible, we use automation to reduce detection and response time. Alerts from SIEM, EDR, XDR and other security platforms are automatically correlated and triaged using pre-defined rules. Incidents that require human analysis are prioritised based on severity and business impact.

Building Resilience

Incident response is not just about cleaning up after an attack — it’s about building a culture of preparedness. We run regular tabletop exercises, red team simulations, and cross-departmental workshops to test our playbooks and improve coordination under pressure.

Ready When It Matters Most

Cyber incidents are not a matter of “if” — but “when”. That’s why we treat Incident Response as a core capability, not a reactive measure. Through disciplined planning, structured execution, and continuous improvement, we ensure that when incidents occur, our team is ready — and so is our business.
