Domain and DNS Security
You need to make sure your domains are as secure as possible. DNSimple provides everything you need to do just that. With DDoS Defense, account security, registration security, and domain security, we help you safeguard your domains every step of the way.

Network Security
Network security is critical. We make sure your domains stay safe with features included on all plans.
DDoS Protection
When you create an account with DNSimple, your domains are automatically protected by our Distributed Denial of Service protection system. No extra costs. No special configuration required.
Secondary DNS
Uptime, response times, and redundancy are critical when it comes to improving the security of your domain. Use our streamlined Secondary DNS configurations to automatically sync your zone to or from other DNS providers.

Domain Security
Taking extra-steps to make sure your domains are safe doesn't have to be complicated. DNSimple's services create all the DNS configuration needed to secure your domains – without all the extra work.
Let's Encrypt SSL certificates keep your sensitive information secure. Our API fully automates request and renewal of these certificates.
Domain auto-renewal means you don't have to think about when your domains expire or how to renew them. This feature ensures your domain is renewed before it expires.
CAA records ensure only the Certificate Authorities you use are allowed to issue SSL certificates for your domains. This feature protects your domain from mis-issuance.
Our HTTPS redirector secures your site and ensures no one can access communication to or from your website. Available on the professional plan and higher.
Automated domain transfer locks prevent your domain from being unintentionally or unexpectedly transferred.
Whois Privacy keeps the contact information private for your domains. This feature replaces the public information you provide with an anonymous proxy identity in the public WHOIS database.
Domain Access Control lets you specify different roles for your team members on a per-domain basis.
DNS Security
We make securing your DNS simple with Domain Name Security Extensions (DNSSEC) and automatic key rotation.
DNSSEC
Use the same technology for your domains that financial institutions use to protect your data. DNSSEC prevents attackers from spoofing your IP address and redirecting your users to malicious sites.
Automatic key rotation
Further secure your domains with DNSimple's DNSSEC rotation. We'll automatically rotate DS records for domains registered through DNSimple.

Account Security
Protect your domains and your information with DNSimple's account security features.

Multi-factor authentication

We support one-time password authentication apps, external hardware keys (FIDO2, WebAuthn compatible), and platform authenticators such as Windows Hello, Apple Touch ID, Face ID, and Passkeys.
Enforce Multi-Factor authentication for your team
Don't take risks with your account access. Enforcing MFA for your team ensures all account members have an extra layer of protection against unwanted account access. Available on the professional plan and higher.
