Perimeter Security Platforms

We carry the three dominant next-generation firewall families: Fortinet FortiGate, Palo Alto Networks PA-series, and Cisco ASA/Firepower. Sizing is throughput-driven — and the number that matters is throughput with inspection enabled (threat prevention, SSL decryption), which is far below the headline figure. Undersized firewalls are the most common security-hardware mistake we see.

Refurbished firewalls offer excellent value for the hardware itself; note that advanced security services (IPS signatures, web filtering, sandboxing) require active vendor subscriptions, which we can quote alongside the appliance. High-availability pairs are available for environments that cannot tolerate perimeter downtime.

Frequently Asked Questions

Do used firewalls support security subscriptions?

Generally yes — hardware we supply can be registered and licensed with the vendor for threat-prevention services. We can quote the appliance and subscriptions together.

How do I size a firewall correctly?

Use the threat-prevention/inspection throughput figure, not the raw firewall throughput, and size for your internet bandwidth plus growth. Share your bandwidth and user count and we will recommend a model.

Can you supply firewalls as an HA pair?

Yes — we supply matched pairs (same model, compatible firmware) ready for active/passive or active/active high-availability configuration.
