5 criteria to check before purchasing a firewall
Before selecting a device, businesses should check five main factors:
1. Security performance
Do not only consider firewall throughput. IPS throughput, threat protection throughput, and SSL inspection throughput should also be checked.
2. System scale
The device should support the number of users, branches, servers, and expected future traffic.
3. Management capabilities
Businesses with multiple firewalls should prioritize solutions that support centralized management of policies, logs, and firmware.
4. Licensing costs
Costs should include the device, subscription, technical support, log storage, and renewal fees.
5. Operational capabilities
A firewall is only effective when policies are controlled, logs are monitored, and firmware is updated regularly.
