In a security incident, product security should lead the investigation, platform should contain the problem and preserve logs and artifacts, and compliance should keep the timeline and track any notification duties with legal counsel. Agree the handoffs before an incident, because nobody thinks clearly about roles at three in the morning.
What each team does
| Phase | Product security | Platform | Compliance |
|---|---|---|---|
| Detect and declare | Declares incident, sets severity | Confirms scope of affected systems | Informed |
| Contain | Directs priorities | Isolates, rotates, revokes, rolls back | Informed |
| Preserve | Lists what matters | Snapshots logs, images, build records | Records what was kept and when |
| Investigate | Leads root cause work | Supplies system access and data | Keeps the timeline |
| Notify | Provides technical facts | Provides impact data | Coordinates with legal on duties |
| Recover and learn | Owns root cause review | Owns fixes to shared systems | Tracks actions to closure |
This is a working split, not a legal one. Notification obligations vary by jurisdiction and contract, so involve legal counsel rather than relying on a blog post.
Preserve before you clean
A frequent mistake is cleaning up first. Redeploying, rotating logs or deleting a compromised build can destroy the record of what happened. Platform should snapshot affected artifacts and export logs to protected storage before remediation where it is safe to do so. NIST CSF 2.0 includes outcomes for incident response plans being established, communicated, maintained and improved (ID.IM-04), which is where this checklist belongs.
Keep one timeline
Compliance, or whoever plays scribe, keeps a single dated timeline: what was seen, when, by whom, what action was taken and by whom. Entries should be factual and timestamped in one agreed time zone. Do not edit past entries. Add corrections as new lines.
Handoff mechanics
- A named incident lead, not a committee.
- One channel for the incident, with a pinned summary that the lead updates.
- A short handoff note at each shift change with state, open actions and next decision.
- A named contact for each team who can pull in others.
- A decision log separate from the chat, so choices are easy to find.
After the incident
Hold a review within a few days while memory is fresh. Focus on process and detection gaps, not blame. NIST SSDF task RV.3.1 asks that identified vulnerabilities are analyzed to determine root causes, and RV.3.2 asks that causes be reviewed over time for patterns. Feed the findings into the RACI and the weekly sync so the lessons change something.
Try it yourself
Click through it at your own pace, or open it full screen. Look at how an early warning shortens the time between detection and the first handoff.
Where Safeguard fits
Safeguard provides zero-day discovery, SBOM and dependency scanning, and asset discovery, which help answer "are we affected and where" early in an incident. It does not replace your incident response plan. A free scan shows what dependency data looks like.
Quick check
Should compliance be in the incident channel?
Yes, as an observer and scribe, with a clear rule not to direct technical work. Early involvement shortens notification decisions later.
Who decides to notify customers or regulators?
That decision belongs to leadership with legal counsel. The technical teams supply facts.
