Untangle NG Firewall Reviews Summary
Author infoRatingReview Summary
Director of Information Technology at a consultancy with 11-50 employees4.0I find Untangle NG Firewall easy to use with solid built-in VPN and reporting features, stable performance, and good real-time alerts, though advanced filtering could improve; support was prompt, and pricing is reasonable compared to competitors.
Information Technology System Administrator at Ίδρυμα Ευγενίδου / Eugenides Foundation4.0I use Untangle NG Firewall mainly for firewalling with captive portal, filtering, threat prevention, bandwidth control, and OpenVPN, which is easy and secure. It’s very stable and performs well, but I want better ad blocking and SSL Inspector options.
Service Delivery Manager at CasCom4.0I use Untangle NG Firewall as a gateway security appliance for client locations due to its comprehensive security features, flexibility, and ROI. It surpasses Meraki in affordability and functionality, though its interface and support accessibility need improvement.
CEO at DragonTech IT Services, Inc4.5No summary available
President at Digital Information LLC4.5No summary available
Owner at ThinkEzIT4.0The most valuable feature of Untangle NG Firewall is its content filtering, though it could improve by including 2FA for SSL VPNs without extra hassle and offering more flexible licensing. Despite its costs, it effectively protects clients and stops threats.
Network and Programming Specialist at Twentytwo Integration5.0Untangle NG Firewall is user-friendly and ideal for home use, but it lacks granularity and in-depth configuration options for engineers. I chose it for its simplicity and switched from Cisco ASA and pfSense due to intrusion protection concerns.
Provincial Program Manager at Human Focus Technologies3.5I find Untangle NG Firewall valuable for endpoint protection management, load balancing, and Active Directory connectivity. However, it slows with many VPN clients. Previously, I used Sophos and am considering Cisco and FortiGate for their scalability and reliability.
