Why DNS matters

DNS is the foundation of how we navigate the Internet — and one of its most exploited weak points.

What Is DNS Security?

The Domain Name System (DNS) acts like the Internet’s address book — translating domain names (like hafnova.com) into machine-readable IP addresses.
Without DNS, accessing online services would be like navigating with raw GPS coordinates.
It is seamless for users, but this invisibility also makes DNS a prime target for cybercriminals.

DNS cyberattacks explained

DNS is a critical attack surface as cyber attackers exploit it to:

  • Redirect users to fake websites (phishing, spoofing)
  • Exfiltrate data via DNS tunneling
  • Launch DDoS attacks through DNS amplification
  • Hide malware communications (C2 servers)
  • Hijack traffic with Man-in-the-middle (MITM) or cache poisoning
DNS is too often overlooked by traditional security tools. It’s a blind spot attackers know and use.

How Hafnova Protects DNS

We protect DNS traffic at its core — for users and security teams:

For Users:

  • No configuration needed — encrypted, filtered DNS on any network
  • Protected on the go, at work, or on public Wi-Fi

For Security Teams:

  • DoHzel: Encrypted DNS (DoH/DoT), policy enforcement, log-level visibility
  • CyberIntel: Real-time threat discovery across domains and digital ecosystems
  • ThreatDB: 100M+ IoCs updated continuously, from trusted global sources

Together, Hafnova ensures DNS traffic is private, verified, and aligned with organizational policy, while enabling real-time detection and mitigation of threats—even before a connection is made.
