Frequently asked questions

What is the difference between DV, OV, and EV certificates?

Domain Validated certificates only verify control over the domain. Organisation Validated certificates verify the legal identity of the business. Extended Validation certificates require rigorous background checks and display the organisation details in certificate inspection windows.

Are free SSL certificates as secure as paid ones?

Yes. Free certificates from providers like Let's Encrypt use the exact same cryptographic algorithms, such as RSA and ECDSA, and provide the same level of data encryption in transit as expensive paid certificates.

Why do SSL certificates expire?

SSL certificates expire to ensure that domain ownership, organisation details, and cryptographic keys remain secure and up to date. Modern industry standards limit maximum certificate lifespans to slightly over one year.
