Multi Domain SSL Certificates


First of all we should know about SSL Certificates, Domain Hosting, Web Hosting Multi Domain. The SSL Certificates are the resources by which web servers prove their identity to web browsers, allowing a secure site to communicate privately with the web browser via the HTTPS protocol.

Features Of Best SSL Certificates

The features of Best SSL Certificates are:

  • Issued by the most trusted certificate authority.
  • A strong level of encryption 128-bit or 256-bit .
  • 99.3% browser ubiquity.
  • 24×7 technical support.
  • SSL secured trust site seal .
  • Installation support.
  • Free re-issuance policy.
  • Easy renewal.

Choosing the Best SSL Certificates for our website is determined by the level of security and encryption needed for our type of site.

Domain Hosting is similar to web hosting. Every website on the Internet needs to be hosted somewhere, so when a company hosts your website, it also hosts the domain where your site is located. Domain Web Hosting usually works on monthly or yearly contracts. Domain Web Hosting services are fairly inexpensive and an excellent method to make your presence felt on the World Wide Web.

A Web Hosting Multiple Domain plan is a type of hosting plan which allows multiple domain names to be attached and allocated to separate portions of the hosting. Hosting options which provide Web Hosting Multiple Domain can be used by clients to host multiple websites and with some configurations, resell resources and provide a hosting service for other customers often known as reseller hosting.

Now we will discuss about Multi Domain SSL Certificates.

A multi-domain certificate (also known as a SAN certificate or Unified Communications Certificate (UCC)) is a special type of SSL certificate. A normal web server certificate can secure one domain name / host name whilst a wildcard certificate can secure all subdomains under one main domain. With a Multi-Domain SSL Certificates we are able to secure one domain name with different domain extensions (e.g. openprovider.co.uk and openprovider.es) or multiple domain names (e.g. openprovider.co.uk and hosting-concepts.com) using one SSL certificate.

Multi-Domain SSL Certificates are certificates that secure multiple domains and multiple hostnames within a domain. Multi-Domain SSL Certificates are ideal for Microsoft® Exchange Server 2007, Exchange Server 2010, and Microsoft Live® Communications Server because they allow us to secure a primary domain, and up to 99 additional Subject Alternative Names (SAN), in a single UC Certificate.

In a shared hosting environment, the UC Certificate “Issued To” will only list the primary domain (but the site seal can list the remaining domains in the SAN).

Multi-domain SSL Certificates are available in Standard and Deluxe forms.

  • Standard (UC) certificate will require domain validation. This certificate type was formerly known as Turbo Multiple Domain SSL.
  • Deluxe (UC) certificate will require domain and business validation. This certificate type was formerly known as High-Assurance (HA).

Features Of Multi Domain SSL Certificates:

  • Secure up to 100 unique domains.
  • Save money over purchasing several SSLs.
  • Save time over managing several certificates.
  • Trusted by over 99% of browsers.
  • 128/256-bit encryption.

Key Advantages of Multi Domain SSL Certificates

  1. The toughest 256 bit encryption, 2048 bit roots SSL Certificate.
  2. Complete Business Organization Validation SSL Certificate.
  3. Comes with Dynamic Geo trust True Seal.
  4. Secure domain.com for free when you order http://www.domain.com.
  5. Up to 25 domain names with a single certificate.
  6. Unlimited server licenses, unlimited free reissues for certificate lifetime.
  7. Includes $150K Guarantee.
  8. Cutting cost is the main benefit to using UCC SSL certificates. If we only use a few domains, we may be fine with typical SSL certificates that cost about $150 each. But once we need five domains, we will need to come up with $750. Think how much we can save on 3 domain names when UCC SSL costs only $300 each.
  9. Another advantage to having UCC SSL is manageability.

Disadvantages Of Multi Domain SSL Certificates

Unfortunately, UCC certificates do have some drawbacks. Security is the first that comes to mind. By using one UCC SSL certificate, all servers hosting all domains share the same private decryption key. Suppose that one of the servers is compromised and a hacker gains access to the decryption key. That hacker now has the ability to read all encrypted messages that are sent to and from the server.

Suppose the UCC SSL certificate is revoked. All domains that use the same certificate won’t be able to properly function. We will have to close down the website while fixing the UCC certificate or getting new SSL certificates for every domain that needs SSL.

Thus Multi Domain SSL Certificates are important tools of online security.
