sslbrain vs DigiCert Trust Lifecycle Manager

Short answer

DigiCert Trust Lifecycle Manager comes as Essentials, Advanced and Premium. Essentials automates with ACME, SCEP, Windows autoenrollment or APIs. Agents and sensors that install on servers, appliances and cloud services come with Advanced.1,2,3,4 Essentials has a public price per seat with a minimum of 25 seats. Advanced and Premium require a sales conversation.1,5 Data can be hosted in the EU by agreement.6,7

sslbrain runs as an appliance in your own network. The catalogue has 72 integrations. On Windows and Linux servers, a service agent installs the certificate. To network equipment and cloud services, the appliance pushes over API or SSH. Where there is no integration, you use a custom agent or ACME.

How to read the table

  • Every answer about another vendor carries a small number. It leads to the source at the foot of the page, with the date the source was last checked.
  • "Not stated" means it does not appear in the sources we reviewed. It does not mean no.
  • Prices are in the vendor's own currency, not converted. Where only the yearly or the monthly price is stated, the other is calculated and marked.
  • The sslbrain column has no source numbers. It comes from our own prices and our integration catalogue and links to those pages.
