Why DNSSEC Matters for Your Domain Security

While DNS is fundamental to the internet, its original design had a critical flaw: it didn't verify if the answers it received were authentic. This opened the door to DNS spoofing or cache poisoning attacks, where attackers could redirect users to malicious websites without their knowledge.

🔐 DNSSEC Fixes This: DNSSEC (Domain Name System Security Extensions) adds cryptographic signatures to DNS data, allowing your computer to verify that the DNS response actually came from the domain's legitimate owner and wasn't tampered with.

How DNSSEC Protects You

Think of DNSSEC as a tamper-proof seal for your DNS records. When you enable DNSSEC for your domain (like `pulsadns.com`), your DNS provider cryptographically signs your zone data. When a visitor's resolver requests your DNS records, it also requests these signatures and verifies them against a chain of trust that leads back to a trusted root key.

Why It's Not Optional Anymore

Enabling DNSSEC is one of the most effective security upgrades you can make for your domain. It's a foundational layer of trust for everything else you build online.
