Intranet SSL


Intranet SSL provides a cost effective solution to secure internal servers, applications, and IP addresses that do not require public trust yet want to benefit from SSL encryption. With Intranet SSL, enterprises receive the same high level of security and certificate features of publicly trusted SSL certificates, but the certificates are issued using GlobalSign non-public CAs. Intranet SSL is available directly via TRUSTZONEs Certificate Management portal.

Beginning 1 November, 2015, the CA/Browser Forum will prohibit the use of internal server names and reserved IP addresses in publicly-trusted SSL certificates.  This means if you normally receive SSL certificates from a public CA (such as GlobalSign), you won't be able to use their certificates for internal server names any more. Intranet SSL from TRUSTZONE allows enterprises to continue to issue SSL to internal server names and reserved IP addresses without the need to run your own CA or use self-signed certificates, because the certificates are issued using GlobalSign's non-public CAs.



  • Continue issuing SSL certificates containing internal server names and reserved IP addresses without the need to run your own in-house CA or use self-signed certificates.
  • Secure internally used domain names and servers that do not require public trust.
  • Issue certificates with options which would otherwise not be permitted under public hierarchies including the use of SHA1 and 4-5 year certificates.
  • Utilize GlobalSign's WebTrust-certified infrastructure and management tools to discover, track, report, and manage all certificates across a dynamic server inventory.

IntranetSSL supports the issuance of SSL certificates with Internal Server Names and Reserved IP addresses in the CN and SAN values; furthermore, mix and match internal, FQDNs, sub-domains, wildcard, and Global IP addresses in one certificate using a single certificate under a non-public GlobalSign root.

  • Internal Server Names
  • (mail)
  • Local Host Names (mysite.localhost)
  • Reserved IP Address (
  • Fully Qualified Domain Name (
  • Sub-Domains (
  • Wildcard (*
