Fortinet
Perimeter firewall, VPN, and SD-WAN in one appliance
What it is
Fortinet, through its FortiGate line, offers next-generation firewalls (NGFW) that combine traffic inspection, VPN, intrusion prevention (IPS), and SD-WAN in a single physical or virtual appliance, with centralized management across sites. It's one of the options we evaluate within DITAP Security for clients who need a robust, auditable security perimeter.
We typically pair it with the multi-WAN and connectivity work we already do at DITAP Core, so failover and firewall policy stay consistent end to end.
When we recommend it
We recommend Fortinet when:
- The client needs firewall, VPN, IPS, and SD-WAN unified in a single appliance with centralized management, instead of separate tools.
- There are multiple sites requiring permanent site-to-site VPN and consistent security policies between them.
- The environment has compliance requirements that value a recognized security vendor, with threat-signature updates maintained by the manufacturer.
- The goal is combining SD-WAN with multiple connectivity paths (for example, fiber + Starlink) under failover policies controlled by the same device.
- The client's sector (healthcare, banking, government) demands a firewall with a track record of internationally recognized security certifications.
How we implement it
Our Fortinet management covers the full perimeter-security cycle:
- Segmentation policy and IPS profile design tuned to the client's actual traffic, not generic factory rules.
- Site-to-site VPN configuration between locations and remote-access VPN for the team.
- SD-WAN configuration for load balancing and failover across the internet links available on-site.
- Ongoing threat-signature management, firmware updates, and periodic firewall-rule review.
- Periodic reports on traffic and blocked incidents, so the client has real visibility into what the appliance is actually stopping.
Alternatives
Fortinet isn't the only perimeter security layer we implement:
Cloudflare
a better fit when the priority is protecting public web applications and remote access without a physical on-site appliance.
pfSense / OPNsense
a lower-cost open-source alternative for clients with technical staff capable of running a more hands-on firewall.
Ubiquiti Security Gateway
enough for smaller sites already on UniFi that don't need FortiGate's advanced features.
