FireEye Detection On Demand vs Zscaler Cloud Sandbox: 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 Cloud Sandbox

Mid-market and enterprise security teams handling encrypted traffic need Zscaler Cloud Sandbox because it performs TLS/SSL inspection and delivers file verdicts in real time without blocking user workflows, a combination most sandboxes abandon for speed. The AI model trained on 600M+ samples plus Single Scan, Multi-Action detection catches polymorphic malware that static rules miss, and the Zero Trust Browser integration keeps users productive during analysis rather than stuck behind a hold screen. Skip this if your organization runs isolated air-gapped networks or processes mostly document-based threats; the value compounds with high email volumes and encrypted web traffic at scale.
