FortiGuard DNS Filtering Service
What FortiGuard DNS Filtering Service is
FortiGuard DNS Filtering Service is a network security service that evaluates DNS requests against FortiGuard domain ratings and helps identify unusual DNS behavior linked to malicious activity, compromised systems, or rogue-domain staging areas. It blocks requests to known botnet command-and-control domains and rejects queries to staging sites to help prevent infiltration and exfiltration attempts, including DNS leaks. DNSSEC signatures verify DNS response authenticity, while request limits help protect against DNS flood attacks. The service also inspects encrypted DNS traffic over TLS and HTTPS, and full DNS traffic inspection detects application, volumetric, and anomaly attacks, including DoS and DDoS attacks. Fortinet describes uses that include protection from DNS spoofing and cache poisoning, improved reliability, and privacy benefits from encrypting DNS traffic to help prevent interception or tracking of queries. Listed Security Fabric integrations include FortiGate, FortiProxy, FortiDDoS, FortiXDR, and FortiTrust. Fortinet presents the service for enterprise, small and mid-sized business, and service provider customers. Fortinet was founded in the San Francisco Bay Area in 2000 and is headquartered in Sunnyvale, California. Pricing is on request.
