The average security incident costs 277 days to identify and contain. Most of that time isn't spent fighting the threat,  it's spent figuring out *what to do next.* - Who gets notified first? - What gets isolated, and how fast? - What do you tell customers and when? - What does legal need before you say anything? If your team is Googling these answers mid-incident, you've already lost time you can't get back. ![Aug-IR-Checklist-Email-Graphic-cmpwb](https://info.cyberclan.com/hs-fs/hubfs/2026%20Graphics/Aug-IR-Checklist-Email-Graphic-cmpwb.png?width=500&height=500&name=Aug-IR-Checklist-Email-Graphic-cmpwb.png "Aug-IR-Checklist-Email-Graphic-cmpwb") ## A Checklist Built for the First 72 hours and Beyond This isn't a theoretical framework. It's a practical, print-and-post checklist covering: - **Detection & Triage** — Confirm the incident, assess severity, assign an incident commander - **Containment** — Isolate affected systems without destroying forensic evidence - **Communication** — Internal escalation paths, legal notification thresholds, customer messaging - **Eradication & Recovery** — Remove the threat and safely restore operations - **Post-Incident Review** — Turn the incident into a stronger defense next time Built by security practitioners who've run real incident response — not written by a marketing team guessing what sounds good. # Used by security teams who don't get second chances. #### "We had this printed and taped inside our IR binder within a day. During our last incident, it cut our response confusion in half." #### *"Simple, no-fluff, and actually usable at 2am when something's on fire."* --- ## Questions? **Is this really free?**  Yes — no trial, no credit card, no catch. **Is this specific to a certain industry?**  No. The framework applies to any team responsible for IT, security, or data protection. **Will I get sales emails after this?**  We'll send you a couple of related resources. You can unsubscribe with one click at any time. **Is this enough on its own, or do I need more?**  This checklist covers the core response framework. Many teams pair it with a full incident response *plan,* we can point you to resources for that too, no strings attached.
