Resec Gateway Security vs Zscaler Cyberthreat Protection: Side-by-Side Comparison (2026)

Resec Gateway Security

Mid-market and enterprise security teams handling high-volume file traffic will see immediate value in Resec Gateway Security's Content Disarm and Reconstruction engine, which neutralizes threats by rebuilding files rather than just blocking them. The platform covers NIST PR.IR and PR.PS with cluster-based architecture and on-premise deployment options, giving you genuine resilience without forcing cloud-only dependencies. Skip this if your priority is threat hunting and forensics; Resec emphasizes prevention and sanitization over the continuous monitoring and investigation tooling that detection-heavy teams need.

Zscaler Cyberthreat Protection

Mid-market and enterprise security teams treating network perimeter enforcement as obsolete will get the most from Zscaler Cyberthreat Protection, particularly those shipping user and device traffic through a zero trust architecture where traditional firewalls fail. Its full TLS/SSL inspection at scale, paired with AI-powered threat detection and DNS security, anchors strong coverage across ID.RA Risk Assessment and DE.CM Continuous Monitoring. Skip this if your organization still relies heavily on on-premises infrastructure or needs mature incident response and recovery workflows; Zscaler prioritizes prevention and detection over the Response and Recovery functions in NIST CSF 2.0.
