Only 1.99% of domains have DNSSEC enabled. The other 86.2% rely on DNS infrastructure that can be quietly manipulated — redirecting visitors to fake sites, or intercepting email, without any visible warning.
What DNSSEC does
DNS is the address book of the internet — it translates your domain name into a server address. DNSSEC adds a cryptographic signature to your DNS records, so that when someone looks up your domain, they can verify the answer hasn't been tampered with.
Without DNSSEC, attackers who can interfere with DNS infrastructure (through cache poisoning or BGP hijacking) can redirect your domain to their own servers — for your website, your email, or both — without your knowledge or your visitors'.
What happens without it
- DNS cache poisoning redirects visitors to a lookalike phishing site with no visible warning in the browser address bar
- Email can be silently redirected to attacker-controlled mail servers
- Compliance frameworks including NIS2 reference DNSSEC as a recommended control for DNS protection
- Enterprise buyers increasingly check DNSSEC status during supply chain security assessments
What fixing it involves
DNSSEC is enabled at your domain registrar — most major registrars (Cloudflare, GoDaddy, Namecheap, 123-reg) support it with a single control panel toggle. The registrar generates signing keys and submits DS records to the TLD registry automatically.
The risk with DNSSEC is misconfiguration after the fact: key rollovers done incorrectly, or moving DNS providers without migrating DNSSEC properly, can make your domain unreachable. Enable it correctly once and leave it alone.
