FireEye Detection On Demand vs Zscaler Advanced Threat Protection: Side-by-Side Comparison (2026)

FireEye Detection On Demand

Security teams needing fast, authoritative malware verdicts on suspicious files and URLs should run them through FireEye Detection On Demand before deciding whether to block or investigate further. The cloud API processes submissions through FireEye's actual execution engine rather than signature matching alone, giving you analysis depth typically reserved for expensive incident response retainers. Skip this if your team lacks API integration bandwidth or needs behavioral analysis of binaries already running on endpoints; Detection On Demand is triage and verification, not continuous monitoring.

Zscaler Advanced Threat Protection

Mid-market and enterprise teams that need to inspect encrypted traffic without choking throughput should start with Zscaler Advanced Threat Protection; its inline proxy architecture decrypts and inspects TLS/SSL at scale without the latency tax most organizations accept. The platform prioritizes detection and continuous monitoring over incident response and recovery, covering DE.CM and DE.AE heavily while leaving you to build your own containment workflows. Skip this if your threat model centers on lateral movement within your network or you need deep forensic replay of incidents; ATP is strongest when you're trying to stop threats at the perimeter before they land.
