SSL without a domain name – is it possible?

Sunday, March 29th, 2020

Every website needs an SSL certificate these days to remain accessible via Chrome or Firefox. But can you get SSL  without a domain name? Yes, you can! Instead of securing a domain, you can encrypt a public IP address

Just like with regular certificates, you have a couple of validations options (DomainValidation and Business Validation). Moreover, there’s also a convenience to protect multiple IP addresses under a single SSL certificate.

If you’re looking to secure a private/intranet IP address,  it’s not possible anymore. That ship had sailed in 2016 when the CA/Browser forum voided all intranet SSL certificates.

As for Extended Validation certificates, they don’t support public IP address encryption. So, you’re left with a select number of domain and business validation certificates that can do the job. Here, at SSL Dragon, we offer Sectigo Instant SSL Premium, an affordable BV certificate capable of securing a public IP address, and GoGetSSL Public IP SAN, a multi-domain Domain Validation certificate for IPs you can get within minutes.

But why would a company want to secure a public IP address? What are the benefits? Among the advantages are a verified identity, an extra IP address use (certain services require IP SSL authentication), and visible encryption.

Type 1.1.1.1 in your browser to see an example of a secure public IP address. Used by Cloudflare, the popular content delivery network, 1.1.1.1 is a free app that makes your Internet safer.

Cloudflare uses a public IP address SSL certificate from DigiCert, but our SSL certificates provide the same level of encryption. 

Sectigo Instant SSL Premium comes with the following features:

  • the highest level of encryption and the latest security protocols
  • Business Validation
  • a dynamic site seal to improve customer trust
  • $250,000 warranty for the added peace of mind
  • 99.3% of browser support
  • full compatibility with all the major server platforms and email clients

GoGetSSL Public IP SAN includes the following specs:

  • the highest level of encryption and the latest security protocols
  • secures multiple IP addresses
  • comes with 2 Public IP SANs by default
  • encrypts up to 250 additional SANs on request
  • quick domain validation; no documents required
  • static site seal to further boost visitors’ trust
  • $50,000 SSL warranty against potential breaches
  • supported browsers 99.3%
  • full compatibility with most of the servers and email clients

Now that you know a domain name isn’t always necessary to request an SSL certificate. let’s see how you can secure an IP address with an SSL cert. To apply for a regular certificate, you need to indicate the FQDN (fully qualified domain name) in your Certificate Signing request. Obtaining an IP address certificate is different. This FAQ item explains how to do that. Once your public IP address SSL Certificate is up and running, you can safely store and process sensitive information on your server.
