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.
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
- Prevents Phishing & Malware: Stops attackers from hijacking your domain in DNS to send users to fake login pages.
- Protects Brand Trust: Ensures your customers and email recipients are connecting to your genuine servers.
- Required by Modern Standards: Many government and enterprise security policies now mandate DNSSEC for all domains.
- Easy to Enable: With PulsaDNS, enabling DNSSEC is a simple one-click toggle in your dashboard.
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.
