Fortinet FortiGate

Fortinet designs its own ASICs, the NP7 Network Processor and CP9 Content Processor, that offload firewall sessions, IPsec decryption, NAT, and SSL/TLS inspection entirely from the main CPU. The result is single-digit microsecond latency and line-rate throughput even with all security features enabled, performance that CPU-based firewalls cannot replicate at the same price tier.

FortiOS runs identically across physical appliances, virtual machines, containers, and cloud instances, on AWS, Azure, GCP, and private hypervisors. Every administrator, every policy framework, and every FortiGuard security service is consistent regardless of where a FortiGate is deployed. No retraining, no policy rewriting, no behaviour gaps between on-prem and cloud.

FortiGuard Labs is Fortinet's global threat research engine, processing over 100 billion security events per day using AI and ML models. IPS signatures, AV updates, URL and DNS threat feeds, and application control intelligence are pushed to every FortiGate in near real time, typically within minutes of a new threat being discovered anywhere in the world.

The Fortinet Security Fabric connects FortiGate, FortiSwitch, FortiAP, FortiAnalyzer, FortiSIEM, FortiEDR, FortiMail, and 50+ other products into a bi-directional telemetry mesh. A threat detected at any Fabric node is automatically shared and acted upon across every other node, eliminating the silos that make most multi-vendor environments slow to respond.

Fortinet is the only vendor that natively converges a full NGFW with SD-WAN on the same hardware, the same OS, and the same policy framework. IPS, AV, SSL inspection, URL filtering, and application-aware path selection all run in hardware, eliminating the performance gap that plagues software-only SD-WAN overlays. FortiManager provides zero-touch provisioning across thousands of branch sites.

FortiGuard's AI-based inline malware prevention analyses and blocks zero-day threats in real time, without holding traffic for sandbox queuing. Files are analysed using static analysis, AI/ML heuristics, and dynamic detonation simultaneously. When a verdict is reached, the block and IOC are immediately shared across every FortiGate in the Fabric globally.

FortiOS includes Universal ZTNA as a native capability, enforcing continuous identity and device-posture verification before granting access to any application, regardless of where the user or the application sits. Both agent-based and agentless access modes are supported, replacing legacy VPN trust models without requiring a separate ZTNA gateway.

FortiAnalyzer collects logs, events, and flow data from every Security Fabric node, providing real-time threat correlation, FortiView traffic visibility, compliance dashboards (PCI, HIPAA, ISO 27001), and integrated SOAR playbooks. Mean time to respond is reduced by automating incident response directly from the analytics console, no separate SOAR platform required.

FortiSASE extends the Security Fabric to remote users and thin-branch sites via cloud-hosted PoPs, delivering SWG, CASB, ZTNA, and FWaaS under the same FortiManager console as on-premises FortiGates. Unlike stitched-together SASE architectures, FortiSASE is purpose-built on FortiOS, so policy consistency and threat intelligence are identical on-prem and in the cloud.

FortiGate is one of the few NGFWs with native OT and IoT security services, including OT protocol visibility, vulnerability correlation, and virtual patching for industrial environments. Ruggedised FortiGate models are purpose-built for manufacturing, utilities, and critical infrastructure where standard rack-mount appliances cannot operate reliably.
