Network Security Engineer at Arrow PC Network Pvt Ltd
Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

Advanced visibility has transformed security policies and provides proactive threat prevention
Palo Alto Networks NG Firewalls are powerful, but there are areas for improvement that could enhance their effectiveness, such as cost and licensing models. One of the main challenges we face is the high cost, especially for small to mid-sized businesses (SMBs), with licensing for features such as threat prevention, URL filtering, and WildFire being quite expensive. Additionally, centralized management with Panorama is a dependency for managing multiple firewalls, leading to added costs and complexity, and the built-in centralized management features could be made more user-friendly. Moreover, the learning curve associated with the initial setup and advanced configuration including NAT, decryption, and routing can be complex for new users, and enhancements in logging and reporting could also improve the user experience. There are a few more areas where improvements could streamline operations, such as optimizing commit times. Sometimes committing changes takes a noticeable amount of time, particularly for larger configurations, so a faster commit option would significantly help during urgent troubleshooting. Easier policy troubleshooting is necessary as well. Even though logs are detailed, finding the exact rule match and issue can still be time-consuming in complex environments, so having automated policy simulation and a recommendation tool would expedite troubleshooting. Additionally, better default templates and best practices for SMB data centers and branch offices would speed up deployment and reduce errors. Enhancing integration visibility through a unified dashboard would simplify monitoring, and improving the firmware upgrade process to allow for a more seamless zero downtime upgrade would also enhance operations, as upgrades are stable but typically require careful planning and downtime.
