• Complex interface for non-technical users: Although powerful, the interface can be difficult for beginners and may require experience to manage effectively.
• Frequent firmware bugs and vulnerabilities: Reviewers mention recurring firmware issues that can introduce instability or security concerns.
• Inconsistent technical support experiences: While some users report good support, others describe support as inconsistent or not sufficiently helpful.
• Performance limitations under high CPU load: When CPU utilization exceeds certain thresholds, the system may enter conserve mode, affecting performance.
• Challenges with on-premises integration: Some users report difficulties when integrating Fortinet firewalls with existing on-premises environments.
• Fragmented licensing model: The licensing structure is described as individual and not unified, making it harder to manage across teams or use cases.
