GlobalSign Intermediate Certificates

GlobalSign Intermediate Certificates

Intermediate Certificates sit between an end Entity Certificate and a Root Certificate. They help complete a “Chain of Trust” from your Certificate back to GlobalSign’s Root Certificate. Intermediate Certificates are used by all major Certification Authorities because of the extra security level they provide. GlobalSign has a long-standing history of using Intermediate Certificates for this reason.

GlobalSign has always adopted a high security model when issuing Digital Certificates. We use a trust chain that ensures that the primary GlobalSign root CA (i.e., the Certificate that is pre-installed with all major browsers, applications, and mobiles/hardwares) is “offline” and kept in a highly secure environment with stringently limited access. This means the root CA is not used to directly sign end entity SSL Certificates.

As such, GlobalSign employs a best practices approach for its public key Infrastructure by protecting against the major effects of a “key compromise”. A key compromise of the root CA would render the root and all Certificates issued by the root untrustworthy. By keeping our root offline the key is significantly less likely to become compromised.

GlobalSign Products and their Intermediate Certificates 

Select your product type, then choose the type of Certificate you need based on key size or hash algorithm. Here are Intermediate Certificates for each GlobalSign product:

• TLS/SSL Certificates

  IMPORTANT: If you are installing GlobalSign SSL Certificate, you must install the appropriate Intermediate Certificate onto their web servers. Otherwise, your browsers, applications, and hardware will not be able to recognize GlobalSign SSL Certificates as being trusted. This installation is only necessary once. After installation, all browsers, applications, and hardware that recognize GlobalSign will trust GlobalSign SSL Certificates.
