Untangle NG Firewall

Untangle NG Firewall has built its reputation on making enterprise-style firewall functionality genuinely accessible to small businesses without dedicated IT security staff. The deployment experience is purpose built for generalist IT administrators and MSPs, and very accessible pricing brings comprehensive protection within reach of organisations that would otherwise run with no dedicated firewall.

The honest and appropriate limitation is scale: threat prevention sophistication and application control depth are calibrated for small business needs, and organisations that outgrow SMB scale will find the ceiling reached quickly.

The verdict: right for small businesses and MSPs wanting simple, affordable firewall protection. Mid-market and enterprise organisations should evaluate Sophos Firewall or Fortinet FortiGate instead.
