Detailed Review
Certum is run by Asseco Data Systems S.A. in Szczecin and sits inside the Asseco Group. Its public pages describe it as the largest certification centre in Poland, and say the infrastructure is located in the EU with an in-house data centre.
The shop lists three TLS products: a DV Commercial certificate, an OV Trusted certificate and an EV Premium certificate, each with a stated financial guarantee. Prices are shown in euro, and the shop can also be switched to US dollars or Polish zloty.
Three Products, Three Guarantees
DV Commercial starts at EUR 25 with a EUR 200,000 financial guarantee and certificate issue within an hour. OV Trusted starts at EUR 109 with a EUR 400,000 guarantee, and EV Premium starts at EUR 309 with a EUR 1,000,000 guarantee. DV and OV come in 1, 4, 6 and 10-domain variants and a wildcard version; EV comes in the multi-domain variants.
Shorter Validity Is Spelled Out
Each product page carries a notice that, from 13 March 2026, the maximum certificate validity period is shorter and that at least one free reissue is needed during the product validity. Buyers see this before checkout rather than discovering it at renewal.
A Signature Platform Next Door
The same vendor runs SimplySign, S/MIME certificates and code signing, so a company that already signs documents with Certum can buy its website certificates from the same account. Certum also sells through a reseller network with a partner programme.
Limitations to Consider
Certum is part of a large listed group, so decisions about the product line are not made by an independent certificate specialist. The listed prices are starting prices that depend on the number of domains. The shop and support pages show certificate-by-certificate ordering, so there is no subscription plan comparable to Actalis, and enterprise lifecycle management is not part of the TLS product pages reviewed.
Who Should Use Certum
Companies in Poland and neighbouring markets, and resellers, that want clear per-certificate euro prices and a contracting party in the EU.
