What Is DNSSEC and Should You Enable It?

DNSSEC adds cryptographic signatures to DNS records, letting resolvers verify that DNS responses haven't been tampered with in transit.

The Threat It Addresses

Without DNSSEC, an attacker intercepting DNS traffic could potentially redirect visitors to a fraudulent site without them noticing anything wrong — a technique called DNS spoofing or cache poisoning.

Should You Enable It?

DNSSEC is genuinely valuable for financial institutions, government sites, and any domain where DNS-level trust is critical. For typical small business sites, SSL/TLS already provides strong protection for the actual connection, making DNSSEC a nice-to-have rather than essential.

The Trade-Off

Misconfigured DNSSEC can actually break your domain's resolution entirely — it requires careful setup and should be tested thoroughly if you choose to enable it.
