FortiGate-620B-G Replacement

Replacing the FortiGate-620B-G isn’t just about swapping hardware. It’s about aligning your security architecture with current network demands, improving manageability, and adopting capabilities that better support cloud integration and modern threat prevention.

Role of the FortiGate-620B-G:

A high-performance edge and aggregation firewall, commonly deployed to protect north-south traffic and provide VPN and routing services for large sites and service providers.

Evolving Traffic Patterns:

Encrypted traffic volumes, cloud-bound workloads, remote access, and east-west traffic have grown substantially since the 620B-G was deployed, increasing demands on inspection and throughput.

Modern Demands:

Today’s environments require scalable TLS/SSL inspection, advanced threat protection, integrated SD-WAN, and greater telemetry for hybrid and cloud deployments.

Strategic Upgrade:

Choosing the right successor involves balancing performance, next-generation security features, cloud and orchestration integration, and long-term vendor support to simplify operations and reduce risk.
