When the FortiGate Firewall License Expires

When the FortiGate Firewall License Expires: A Balancing Act Between Functionality and Risk

While a FortiGate firewall will continue to function as a basic firewall after its license expires, it’s crucial to understand the trade-offs and potential security implications that come with this scenario. Here’s a breakdown of what happens and what’s at stake:

1. Limited Security Features:

• Loss of Advanced Protection: Key features like web filtering, antivirus, intrusion prevention, and application control become unavailable. This leaves your network more vulnerable to malware, phishing attacks, and other threats.
• No Threat Updates: You’ll no longer receive the latest security updates and signature files, potentially exposing your network to newly discovered vulnerabilities.

2. Restricted Software Updates:

• Stuck in the Past: You won’t be able to install firmware updates, which often include critical bug fixes, security patches, and performance enhancements.
• Potential Compatibility Issues: Outdated firmware might lead to compatibility problems with other network devices or software.

3. No Technical Support:

• Troubleshooting on Your Own: If you encounter technical issues with the firewall, you won’t have access to Fortinet’s technical support team for assistance.

4. Continued Basic Firewall Functionality:

• Packet Filtering and Routing: The firewall will still perform basic packet filtering and routing functions, allowing network traffic to flow.
• Existing Policies Remain: Existing firewall policies will continue to apply, but you won’t be able to create or modify them.

The Risks of Operating with an Expired License:

• Increased Vulnerability: Your network becomes more susceptible to cyberattacks, data breaches, and malware infections.
• Compliance Issues: Expired licenses might violate industry regulations or contractual obligations, leading to potential fines or penalties.
• Lack of Support: Troubleshooting and resolving issues can be more challenging without access to technical support.

Best Practices:

• Proactive Renewal: Renew your FortiGate license before it expires to maintain optimal security and functionality.
• Temporary Workarounds (If Renewal Delays):
  • Disable expired features to prevent unexpected behavior.
  • Implement alternative security measures (e.g., third-party web filtering).
  • Stay informed about critical vulnerabilities and apply manual patches if possible.

Conclusion:

While a FortiGate firewall can technically operate with an expired license, it’s essential to weigh the risks and limitations carefully. Prioritizing license renewal is the most effective way to ensure your network stays protected and compliant.
