FortiGate 81E Firewall Description
The Fortinet FortiGate 81E Firewall is a compact security appliance that offers a secure SD-WAN solution in a small fanless desktop form factor. With industry-leading secure SD-WAN and system-on-a-chip acceleration, it defends cyber threats in a cost-effective and simple-to-install solution. Through its security-driven networking strategy, Fortinet offers a tight network-to-new-security-generation integration.
USB connection on the Fortinet FortiGate 81E Firewall enables you to seamlessly connect a 3G/4G USB modem from a compatible third party, adding extra WAN connectivity or a redundant link for maximum reliability. The examination is sped up using Fortinet's ninth-generation custom SPU CP9 content processor, which operates away from the mainstream of traffic.
FortiOS, the company's leading operating system, enables the Fortinet Security Fabric to combine high-performance networking with security, resulting in a uniform and context-aware security posture across network endpoints and clouds. The unified approach and naturally developed best-of-breed capabilities enable corporations to operate without sacrificing performance or protection, while also making it easier for people to consume new ideas.
FortiGuard Security Services
In addition to providing thorough security upgrades for the whole portfolio of Fortinet solutions, FortiGuard Labs provides real-time intelligence on the threat landscape. To deliver the greatest generation of protection, the team—which consists of engineers, security threat researchers, and forensic specialists—works with law enforcement agencies, other network and security organisations, and the top threat monitoring companies around the globe.
