Resec Gateway Security vs Zscaler Internet Access: 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 Internet Access

Mid-market and enterprise security teams replacing on-premise web gateways will find Zscaler Internet Access worth the migration effort because it actually inspects encrypted traffic at scale without killing performance, something most cloud SSE platforms struggle with. The platform covers DE.CM and DE.AE through continuous monitoring and AI-powered threat detection across DNS, URLs, and files, giving you visibility into what your old gateway missed. Skip this if your organization needs deep integration with on-prem infrastructure or runs custom legacy applications that depend on transparent proxy architecture; Zscaler's cloud-first design optimizes for modern SaaS and internet access, not hybrid networks.
