Our verdict on FIR (Fast Incident Response)

FIR (Fast Incident Response) is an open-source, self-hosted platform for CSIRTs, CERTs, SOCs, and other teams that need to document and manage cybersecurity incidents. It centers on configurable incident records, letting teams capture categories, severity, status, detection, confidentiality, actors, and remediation plans. Its focus is incident documentation and investigation rather than the full operational lifecycle found in broader incident-management systems.

The recordkeeping features are the main reason to consider FIR. Teams can start records from templates, track open, closed, and blocked statuses, add comments, and maintain both an incident timeline and a separate investigation timeline for technical evidence. FIR can extract artifacts such as IP addresses, hostnames, URLs, email addresses, and hashes, while related files and attributes can be attached to incidents. Logical-operator search and metadata filters help locate records; printable follow-up reports are intended for PDF delivery. This combination suits teams that need structured case documentation and evidence context.

Deployment is self-managed: the project is implemented in Python with Django and supports Docker or a production installation. That makes FIR a better fit for teams prepared to operate a self-hosted tool than for organizations seeking a hosted service. Its documented emphasis is on capturing, investigating, finding, and reporting incidents; buyers who need on-call coordination, escalation policies, status pages, mobile apps, postmortem workflows, or audit logs should consider a product centered on those operational needs. Choose FIR when control over deployment and detailed security-incident records matter more than those broader response workflows.
