Comprehensive Security Services

FortiGate-100D integrates a wide range of security services into a unified platform. This includes a stateful firewall, Intrusion Prevention System (IPS), Anti-Malware, Anti-Spam, Web Filtering, Application Control, SSL Inspection, and both IPSec and SSL VPN. These services ensure that your network is fully protected against viruses, ransomware, intrusion attempts, phishing, botnets, and zero-day exploits.

By leveraging Fortinet’s FortiGuard Security Services, the device provides real-time threat intelligence and automatic signature updates to keep your network defenses current without manual intervention.

Advanced VPN Capabilities

The FortiGate-100D offers full support for both IPSec and SSL VPNs, allowing secure, encrypted remote access to internal resources. It’s ideal for remote workers, branch offices, and BYOD environments. With a maximum of 5,000 IPSec VPN tunnels and 500 SSL VPN users, it scales well with growing remote access demands.

Application Awareness & Control

Using deep packet inspection and Layer 7 filtering, the appliance offers full visibility into application traffic. Administrators can create granular policies to allow, restrict, or prioritize specific applications such as social media, streaming, or cloud services. This feature ensures optimal bandwidth utilization and blocks risky or non-essential traffic.

Secure Web Filtering & Anti-Spam

The integrated web filtering engine blocks malicious, inappropriate, or non-compliant websites based on categories and real-time threat intelligence. It enforces safe browsing policies, limits user access to harmful sites, and prevents malware from entering through phishing links. In addition, the anti-spam engine filters incoming and outgoing emails to reduce the risk of social engineering and spam-based attacks.

FortiOS – The Heart of Fortinet Security

FortiGate-100D runs on FortiOS, Fortinet’s proprietary operating system optimized for security and performance. FortiOS offers a centralized interface for configuring and monitoring firewall rules, VPNs, UTM features, and traffic reports. Administrators benefit from an intuitive GUI, CLI access, REST APIs, and compatibility with FortiManager for large-scale deployments.

Deployment Scenarios

• SMBs: All-in-one secure gateway with low TCO
