Prepare a useful first contact

Incident, vulnerability or data breach: find the right contact

A CSIRT serves a defined constituency: an organisation, sector or community. Its country and FIRST membership do not establish your eligibility, its availability or the services it offers. Check all three on its official website.

Establish the facts
Check the constituency
Confirm the official channel

Incident on your system

Contact the internal team or provider named in your response plan. Look for a CSIRT covering your organisation when external coordination is needed.

Check who it serves, reporting procedures and operating hours; a public form does not guarantee an immediate response.

Flaw in a third-party product

Check the supplier’s disclosure policy or product security incident response team (PSIRT). The /.well-known/security.txt file may specify a contact, policy and encryption details.

Check the domain, Expires field and policy scope. security.txt does not authorise testing; agree on a channel before sending sensitive evidence.

Understand disclosure

Personal data involved

Involve the data controller and data protection officer, if appointed, alongside the technical response team.

Technical assistance and any regulatory notification are separate processes. Have the applicable authority, conditions and deadlines determined for your situation.

Explore data governance

Prepare a useful first contactTimeline with time zone, affected service and observed facts, kept separate from hypotheses.Known scope and impact, actions already taken and a person authorised to communicate.Redacted summary and agreed sharing channel; no passwords, tokens or complete logs in a public form.

This checklist prepares a conversation; it measures neither incident severity nor resolution. Selections stay on this page and are not sent.
