HarfangLab EPP Antivirus vs USB Firewall: Side-by-Side Comparison (2026)

HarfangLab EPP Antivirus

Startups and SMBs with multi-OS environments will get real value from HarfangLab EPP Antivirus because it handles Windows, macOS, and Linux detection from a single dashboard without the licensing bloat of larger platforms. The IKARUS engine delivers signature-based detection plus behavioral analysis, and the virtual sandboxing for file execution actually catches polymorphic malware that signature-only tools miss. Skip this if you need NIST Respond capabilities built in; HarfangLab is detection and containment focused, leaving incident response and remediation to your other tools.

USB Firewall

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.
