CST VerdictShort answer
Mid-market and enterprise teams that need to stop phishing before it reaches inboxes will find Fortra SWG's remote browser isolation and AI-powered detection genuinely useful, especially if you're enforcing zero trust on web traffic without managing multiple point products. The platform scores strongly on NIST PR.DS and DE.CM, meaning data protection and anomaly detection are built in rather than bolted on. Skip this if your priority is lateral movement detection inside the network; Fortra is perimeter-focused and won't replace what your EDR should be catching. 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.
