Certum SSL is a paid family of SSL/TLS certificates from Certum by Asseco Data Systems S.A. for encrypting website traffic and protecting information exchanged between websites and visitors. Its options suit website owners and organizations that need a choice of validation level, from domain-validated Commercial SSL to organization-validated Trusted SSL and extended-validation Premium SSL. The product range is described for blogs, online stores, business websites, public administration, financial services and other organizations, with cloud deployment.

Coverage is a key distinction: wildcard certificates support subdomains, while multidomain certificates secure multiple domain names on one certificate. Commercial SSL also supports ACME, and certificates can be reissued during the product validity period. These features make the range relevant to buyers seeking certificate automation or broader domain coverage, though ACME support is specified only for Commercial SSL. Issuance is listed in hours, while activation and verification depend on certificate type and may involve domain-control checks or organization documentation.

The offering has no free plan, and the provided plan structure does not establish prices for each certificate type, so buyers should compare the applicable product and validation requirements before choosing. Email, phone and documentation are listed as support channels. Certum SSL is a fit for buyers who want DV, OV or EV choices alongside wildcard or multidomain coverage; it is less suitable for those requiring a free certificate or ACME support across all validation types. The product’s validity terms should be checked at purchase, since applicable limits can depend on issuance date.

    • Activation and verification vary by certificate type and may require documentation.
    • ACME support is specified for Commercial SSL, not the other certificate types.
