FortiGate Firewall

FortiGate’s DPIs can examine the content of every message and recognize the applications used to send or receive them, unlike normal stateful packet inspections, which check only headers, destination IP, and source IP. Fortinet’s approach includes analyzing data encrypted with SSL/TLS, ML to learn unusual patterns, SoCs for rapid response, and firewalling for traffic processing. FortiGuard IPS and OT security services provide real-time intelligence for intrusion prevention and blocking threats.

IP Sec VPNs utilize AES (Advanced Encryption Standard), 3DES (Triple Data Encryption Standard), Blowfish, ChaCha, and DES-CBC to create secure communication channels in the network layer. On the other hand, SSL VPNs use TLS (Transport Layer Security) protocols to support encryption like AES, RSA, and Elliptic Curve Cryptography (ECC), operating at the application layer. The encryption algorithms or keys are crucial for protecting information from cyber threats, maintaining privacy, and ensuring trust.

FortiGate’s IPS is implemented through its security processors and FortiGuard Labs, which secures the entire infrastructure through an industry-leading threat intelligence system. The IPS uses a broad IPS library based on FortiGuard research. Embedded with more than a thousand zero-day threat discoveries, the IPS gets complete control of attacks with its detection and evasion techniques. It employs real-time traffic analysis, behavior-based detection, and up-to-date threat intelligence instead of relying just on known signatures.

Fortinet’s SPUs boost the efficiency, speed, value, and scale of your cybersecurity solutions. They provide secure computing power for network and content processing operations and include functions like Layer 7 firewall, IPS, antivirus, and speeding up of IPv4, IPv6, and unicast. In short, they accelerate and unify network and security to achieve operational efficiencies to deliver a high-performance application experience. Experience the best ROI, and reduced power and space requirements with fast and SPU chips

On enabling deep inspection, FortiGate stops the SSL/TLS connection and decrypts the encrypted traffic, and inspects its content, applying features like antivirus, web filtering, etc. After scanning for content threats, it re-encrypts the traffic, certifying the content with its own Certificate Authority (CA) and further forwards it to the destination without compromising network security.

FortiGate’s secure SD-WAN intelligently routes traffic across multiple connections while implementing firewalls, IPS, and centralized management capabilities at a more granular level. SD-WAN enables application-aware routing, which means it prioritizes critical traffic. It routes traffic based on performance metrics like bandwidth, latency, jitter, etc., to enhance user experience with its dynamic path selection capability. This ensures uptime, secure application access, centralized control, and real-time threat protection from a single platform.

Fortinet ZTNA continually examines who and what is using the system’s resources while giving you full visibility and control over what is connected on your network. To protect networks and applications in remote locations, ZTNA is used to enforce user and device verification before granting access. With device posture checks, identity-based policies, and a consistent authentication process, only the trusted endpoints are connected. It also integrates FortiClient and FortiAuthenticator for secure and granular access control, enhancing endpoint security.
