Free but may cause troubles **Rating:** 1.0/5.0 stars **Reviewed by:** Fabio A. | Marketing Director, Small-Business (50 or fewer emp.) **Reviewed Date:** April 30, 2016 **What do you like best about Comodo Firewall?** It is light, not like other firewall and Internet Security (I used it as part of the free Internet Security suite). It does not make start-up heavy and it does not bother you that much, it is a discrete presence. **What do you dislike about Comodo Firewall?** It causes problems with other software and networking. On one of my laptops it just makes the connection drops and randomly disable the wifi adapter. Not only, after uninstalling the software a whole bunch of registry keys remain active in the registry and cause even more subtle problems. I had to clean the registry manual myself to get everything back to normal. On another laptop, again after uninstalled, the software with its persistent registry keys prevented Microsoft Security Essential to open its interface, eveything back to normal after I cleaned the registry myself from all the left-over Comodo keys. In general then the interface is not as friendly 8beside the pretty colours...) and some features are not so easy to understand where they are. In a couple of cases it did not prevent malware oftware to pass even though then Comodo was able to stop its action. **Recommendations to others considering Comodo Firewall:** I used it on Windows 7 and did not give me the problems I mentioned. But I totally not recommend it for Windows 10, maybe they'll fix the bugs but anyway but the issues that it may cause make it not worth it right now. Hopefully they will improve it int he future. **What problems is Comodo Firewall solving and how is that benefiting you?** Security while browsing over internet and using softwares in general. I have used it for over 4 years and lately with Windows 10 and the latest updates it did cause more trouble than benefits. ## Comodo Firewall Discussions - [What is Comodo Firewall used for?](https://www.g2.com/discussions/what-is-comodo-firewall-used-for) - [What is the best firewall protection?](https://www.g2.com/discussions/what-is-the-best-firewall-protection) - [Is Comodo still free?](https://www.g2.com/discussions/is-comodo-still-free) - [Is Comodo free firewall any good?](https://www.g2.com/discussions/is-comodo-free-firewall-any-good) - [Is Comodo firewall good?](https://www.g2.com/discussions/is-comodo-firewall-good) - [View Comodo Firewall pricing details and edition comparison](https://www.g2.com/products/comodo-firewall/reviews?filters%5Bnps_score%5D%5B%5D=1§ion=pricing&secure%5Bexpires_at%5D=2026-08-13+02%3A22%3A19+-0500&secure%5Bsession_id%5D=22ad9b7d-5411-45bf-9575-18ec6dd1112a&secure%5Btoken%5D=7eb8337939f9df84cdabf8ce5dcc5a0b64287be8ccbb55018660a88d8d0eeed1&format=llm_user) ## Comodo Firewall Features **Additional Functionality** - Penetration Testing - Alerts/Notifications - Audit Trail - Anti Virus - Vulnerability Scanning - Remote Monitoring & Management - VPN - Behavior Analytics - Reporting/Analytics - Real-Time Notifications - Access Controls/Permissions - SSL Security - Patch Management - Event Logs - Anomaly/Malware Detection - DNS Leak Protection - Third-Party Integrations - Server Monitoring - Real-Time Monitoring - Compliance Management - Network Provisioning - API - Email Alerts - Security Auditing - Intrusion Detection System - Data Visualization - Two-Factor Authentication - Generative AI - Firewalls - AI Copilot - Anti Spam - Threat Response - Activity Monitoring - Risk Alerts - Data Loss Prevention - Single Sign On - Intrusion Prevention System - Secure Login - Policy Management - Activity Dashboard **Administration** - Policy Management - Logging and Reporting - Application Gateway - Concurrent Sessions - Uptime Reporting - Web Traffic Reporting - Compliance Management - Access Management - Incident Management - Audit Management - Remote Monitoring & Management **Agentic AI - Firewall Software** - Autonomous Task Execution - Adaptive Learning - AI/Machine Learning **Functionality** - Virtual Private Network (VPN) - Antivirus - URL Filtering - Availability - IP Filtering - Content Filtering **Monitoring** - Load Balancing - Continuous Analysis - Intrusion Prevention - Intrusion Detection - Intrusion Detection System - Intrusion Prevention System **Generative AI** - AI Text Summarization - Generative AI **Artificial Intelligence - Firewall** - AI Firewall **Additional Functionality** - Spam Blocker - Alerts/Escalation - Role-Based Permissions - Network Monitoring - Visual Analytics - Customizable Reports - Real-Time Analytics - Reporting & Statistics - Anti Spam - Activity Dashboard - Real-Time Monitoring - Real-Time Notifications - Activity Tracking - Hardware Integration - Summary Reports - Alerts/Notifications - Access Controls/Permissions - Real-Time Data - Server Monitoring - Two-Factor Authentication - Log Access - Reporting/Analytics - Multi-Location - SSL Security - Behavior Tracking - AI Copilot - API - Event Logs - Vulnerability Scanning - Risk Alerts - Single Sign On - Dashboard Creation - Monitoring ## Top Comodo Firewall Alternatives - [Sophos Firewall](https://www.g2.com/products/sophos-firewall/reviews) - 4.7/5.0 (817 reviews) - [Netgate pfSense](https://www.g2.com/products/netgate-pfsense/reviews) - 4.7/5.0 (318 reviews) - [GlassWire Firewall](https://www.g2.com/products/glasswire-firewall/reviews) - 4.6/5.0 (49 reviews)
