CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
FireEye customers running Mandiant products will get immediate value from Highlighter because it closes the gap between detection and forensic depth without adding another vendor to your stack. The integration surfaces artifact data directly in your existing FireEye workflows, cutting investigation time on confirmed incidents. Skip this if you're not already committed to the FireEye ecosystem; Highlighter is a tightly coupled extension, not a standalone forensics platform.
Mid-market and enterprise security teams drowning in alert volume will see the immediate payoff from Autonomous Mode; its AI agent handles triage and investigation in parallel, cutting mean time to respond by eliminating the manual handoff between your SOC and forensics team. The tool addresses both NIST DE.AE and RS.AN functions, meaning it actually closes the gap between detection and investigation rather than bolting them together. Skip this if your team needs deep customization of investigation workflows or tight integration with legacy SIEM platforms; Autonomous Mode assumes a cloud-native posture and expects you to trust the agent's judgment calls.
