UC Multi-Domain SSL

Get powerful SSL-Based security for your UC-enabled communications environment

Entrust UC Multi-Domain SSL Certificates have been developed primarily for use with Exchange, Lync, or Skype for Business Servers or environments where you need to secure multiple names across different domains. Our UC Multi-Domain SSL Certificates use Subject Alternative Names (SANs) to secure 250 domains, websites or subdomains with one certificate.

What are UNIFIED COMMUNICATIONS SSL Certificates Secure?


The defining feature of a UC SSL Certificate is the use of the SAN field in the certificate. In the SAN field any number of different domain names or common names. UC SSL Certificates are more cost efficient because they can secure external network names and be enabled to work on any included domain.

For example, you could get one UC Multi-Domain SSL Certificate to cover:

  • yourdomain.com
  • mail.yourdomain.com
  • autodiscover.yourdomain.com
  • example.com
  • dev.example2.com

Why use the Entrust TRUSTWORTHY SITE SEAL?


Let your visitors know they are on a secure Web site, with the Entrust Site Seal. It’s been proven that customers have increased confidence and lower “abandonment” when you use a site seal. The Entrust Site Seal establishes your business as a safe place to do online business, giving users a higher level of trust.


In today’s business environment, it is imperative that organizations establish trust with their customers online. The best way? Let your visitors know you have taken steps to ensure the security of their information by clearly displaying the Entrust Site Seal.*


  • Posting the Entrust Site Seal on your Web site let’s your visitors know that you are committed to online security.
  • Unless you deploy Extended Validation Certificates, the only indication of a secure connection customers receive is a small lock on the bottom of Web browsers. Customers may not know to look for this lock, but will be assured by a security seal.
  • Reduces shopping cart abandonment and increases order completions.
  • Just by clicking the Entrust Site Seal, visitors can verify your site’s authenticity and certificate status.

Entrust is recognized as a trusted security brand for more than a dozen years, providing layered security solutions that help instill confidence for consumers, enterprise and governments. Now you can leverage that brand to help secure the identities of your own customers.

Front Line ENCRYPTION


Your website’s security is our number-one priority. That’s why Entrust OV SSL Certificates feature ECC public key encryption in our root certificates. With support for SHA-2 algorithms, Entrust SSL Certificates protect your data by offering stronger security and increased performance.


ELLIPTIC CURVE CRYPTOGRAPHY (ECC)


Security providers work continuously to innovate technology to upend hackers who are diligent in their efforts to craft clever new ways to steal data. Advanced ECC, while not new, uses a different approach than standard RSA. RSA draws its strength by using increasingly larger logarithms, which take more time to process. ECC, on the other hand, relies on discovering a distinct logarithm within a random elliptic curve. The larger the elliptic curve, the greater the security. Using a random formula improves the encryption strength while a smaller logarithm increases the performance of digital certificates.


BENEFITS


Stronger Keys


ECC uses a smaller algorithm to generate keys that are exponentially stronger than RSA keys.


Increased Performance


The smaller algorithm means less data is being verified between the server and the client, which translates to increased network performance. This is especially important for websites that experience a high level of traffic.


Is ECC RIGHT FOR YOU


Entrust SSL Certificates using ECC technology are ideal for scenarios where server-load performance is critical, and site visitors and the Web/app server are known to be compatible with ECC keys.

Entrust UC Multi-Domain SSL Certificates for EXCHANGE, LYNC and SKYPE FOR BUSINESS SERVERS


To use the Domain Security feature in a UC SSL Certificate, Microsoft works with public X.509 certification authorities (CAs) to enable secure client access from the Internet to Exchange, Lync and Skype for Business servers.


A UC SSL Certificate from Entrust allows you to deploy the Domain Security feature and enable secure client access from the Internet. While developed for Unified Communications applications, Multi-Domain SSL can benefit anyone looking for simplicity of consolidating many domain names into a single SSL Certificate and single IP address.


Completing the Certificate Enrollment Process


When you buy an Unified Communications SSL Certificate you can add additional domains using the Subject Alternative Name (SAN) extension.


Before you attempt to complete the online certificate enrollment process, take a look at our SSL Enrollment guide. Enrolling is faster and easier if you have collected the information you need before beginning the enrollment process.

What is the SUBJECT ALTERNATIVE NAME field?


In cryptography, X.509 is a standard for a public key infrastructure (PKI) and Privilege Management Infrastructure (PMI). X.509 specifies standard formats for public key certificates, certificate revocation lists, attribute certificates and a certification path validation algorithm.


The Subject Alternative Name is an extension to X.509 that allows various values to be associated with a security certificate.


The purpose of a certificate with SAN is the same as that of other certificates. It provides a means for a server to establish its identity and then set up a secure communication. Certificates with SAN also provide a subject alternative name field that allows additional domain names to be protected with just one certificate.


SAN Certificates or UC SSL Certificates provide significant cost savings in many situations because they secure multiple domain names or sub-domains in one certificate. This can simplify situations that would require multiple IP addresses because one IP address per certificate is normally required.


What can you do with Subject Alternative Names?


  • Secure host names on different base domains in one SSL Certificate.
  • Virtually Host Multiple SSL sites on a single IP address.
  • Greatly simplify your Exchange Server SSL configuration.

WHICH SSL CLIENTS support Subject Alternative Names?


Most mobile devices support Subject Alternative Names.


Internet Explorer, Firefox, Opera, and Safari have all supported Subject Alternative Names since 2003.
