FORRESTER REPORT

# The Forrester Cybersecurity Incident Response Services Landscape, Q3 2026

## Forrester's Overview Of Notable IR Services Vendors.

## Build resilience before the crisis hits. Choose the right IR partner for your business.

Modern breaches demand more than reactive breach investigations; they require strategic partners who are prepared to handle AI-driven attacks, can protect legal defensibility, and keep your business resilient and operational.

This Forrester report guides security leaders on choosing the capabilities that matter most for your technology evaluation and provider selection criteria for CIRS providers on your needs.

**The report covers:**

* The market shift from emergency response to long-term operational resilience

* Scenarios such as AI/agentic system incident response, executive and board communications support, and post-incident transformation

* Defensibility considerations of AI-assisted incident response

* Best practices for establishing standing-response partnerships
