Use Cases and Deployment Scope
Two of our major sites are currently protected by Fortinet FortiGate Enterprise level products. Both sites have an HA Fortigate solutions ensuring network segmentation, network protection (IDS, WAF, Firewall, SSL inspection, .....) and IPSec VPN connection towards our cloud services, telco operators and remote sites. Our cloud services and remote sited aren't using Fortinet technologies and are a mix of other brand security appliances and products but the integrations has been quite easy. Actually, even if we can find similar services and products offered by many other companies, I find the Fortinet line of products a bit easy to maintain while leveraging all the availability, resilience and security we need.
