One of the most misleading questions in firewall operations is: “Does it still work after the license expires?” “Works” can mean several different things. It may still forward packets. NAT may still f
High Availability is about failure domains. Consider this architecture: Two ISPsTwo firewallsOne core switch Is it redundant? At the firewall layer, yes. At the network level, no. The switch remains a
Redundancy is about failure domains. Not interface count. Consider a hypervisor with two 10 GbE NICs. Both are bonded. Both cables connect to the same switch. A NIC failure is survivable. A switch fai
Here's an easy way to create a Monday morning outage: Upgrade the firewall Discover a remote-access feature disappeared Start designing the replacement while users are calling FortiOS 7.6.3 provide
Poor Firewall Sizing Metric When Used Alone “How many users?” It's probably the most common firewall sizing question. But users don't generate sessions. Devices and applications do. Consider one emplo
A datasheet says: 10 Gbps firewall throughput. Excellent. But what happens when you enable: IPS? TLS inspection? Malware protection? Application control? VPN? Performance metrics exist because those a
A degraded Internet circuit can be worse operationally than a failed one. When it fails completely, failover is obvious. When it remains barely functional, users may suffer for hours. A useful SD-WAN
Infrastructure hardware tends to get replaced for two bad reasons: Reason 1:It is old Reason 2:A newer model exists Neither tells us whether replacement is justified. Consider a firewall. It still wor
