I found the upgrades valuable.
FortiGate Next Generation Firewall (NGFW) offers easy setup and user-friendly interfaces, with high performance in firewall capabilities. Its scalability suits different network sizes, enhanced by SSL inspection and threat intelligence features. Despite valuable firewall and VPN functions, NGFW faces challenges like costly pricing, inflexible licensing, and unhelpful technical support. Security enhancements in IPS/IDS and vulnerability management are needed, along with improved SD-WAN integration and virtual machine flexibility for larger environments.
