CST VerdictShort answer
Mid-market and enterprise security teams handling high-volume file traffic across email and web gateways should prioritize Glasswall ICAP for its content disarm and reconstruction engine, which removes threats without blocking legitimate files. The tool's ICAP server architecture integrates directly into existing proxy and gateway infrastructure, meaning you get real-time threat removal without ripping out your perimeter stack. Skip this if your organization relies heavily on allow-listing or has minimal file exchange friction; ICAP overhead becomes unjustifiable when your threat model doesn't center on malicious document payloads. Mid-market and enterprise security teams that need to block data exfiltration via USB without reimaging endpoints should evaluate USB Firewall; its department-level control granularity and air-gapped system support handle the specific use cases where USB remains your actual attack surface. The tool maps directly to PR.AA and PR.DS in NIST CSF 2.0, with centralized logging that satisfies audit requirements most endpoint platforms ignore. Skip this if your threat model prioritizes detection and response over prevention, or if you need USB controls as a secondary feature bolted onto a broader EDR suite.
