Certum Premium EV SSL

EV

Certum Premium EV SSL is an SSL certificate with extended validation (EV) from the Certum certificate authority.

It protects one name: the domain and, usually, its www version.

The strictest check: legal status, physical address, the authority of the person placing the order, and a call to a verified number. Browsers no longer show the green bar with the company name, so EV is bought when a regulator, bank or counterparty requires it.

The encryption is the same as in any other certificate: modern RSA or ECC keys and TLS 1.2–1.3. You pay for validation, paperwork and warranty, not for a “stronger” padlock.

Good fit

When you do not need it

  • You want the “green bar” — it is gone
