What is incident response?
What happens in the first hour after something breaks, decided before it breaks.
In short
Incident response is the prepared way a team handles something going wrong in production, whether an outage, a data leak or a bad release: noticing it, deciding who leads, containing the damage, restoring service, telling the people affected and writing down what to change so it does not happen again. It is decided in advance, not improvised during the incident.
Also called: Incident management, On-call, Postmortem
Why it matters when your prototype goes to production
A prototype has no incidents, only bugs. With paying users, a broken release at 11pm is an incident, and the questions arrive all at once: who noticed, who decides to roll back, who tells customers, and is any data affected? A team that answers those questions for the first time during the incident loses the most time.
A plan that fits a small team
- Alerts reach a named person, with a backup.
- A way to stop the damage quickly: roll back, or switch the feature off.
- A place to talk and a person in charge.
- Status updates to customers, even when the news is "we are on it".
- A blameless write-up afterwards, with the changes that prevent a repeat.
For security incidents, NIST's guidance (SP 800-61 Revision 3, April 2025) is the standard reference, and a data breach can carry legal notification duties, so decide in advance who makes that call.
Common questions
What is a blameless postmortem?
A written review of an incident that looks for the causes in systems and processes rather than blaming individuals, so people report problems honestly.
