BUSINESS

Verifies the domain and the organization behind the website.

  • Organization identity checked

EXTENDED

EV · Extended Validation

Uses extended organization verification for higher identity assurance.

SSL FAQ

Common SSL certificate questions

Clear answers for customers, search engines and AI search systems.
Which SSL certificate should I choose?
Choose Single Domain SSL for one website, Wildcard SSL for one domain and its first-level subdomains, or Multi-Domain SSL for several different domains. Then choose DV, OV or EV based on the identity verification you need.
What is the difference between DV, OV and EV SSL?
DV verifies domain control. OV also verifies the organization behind the website. EV uses extended organization verification for higher identity assurance. The main difference is verification depth, not basic HTTPS encryption strength.
Can one SSL certificate secure multiple domains?
Yes. A Multi-Domain SSL certificate can secure multiple different domain names, subject to the plan's domain limits.
Does SSL make a website trustworthy?
SSL encrypts the connection and enables HTTPS. It does not by itself guarantee that a website or its content is trustworthy. OV and EV add organization identity verification for use cases that require it.
How long is a publicly trusted TLS certificate valid in 2026?
Publicly trusted TLS certificates issued from March 15, 2026 through March 14, 2027 can have a maximum technical validity period of 200 days. Longer commercial subscription terms may therefore require reissuance during the subscription period.
Can I reissue my SSL certificate?
NiceNIC SSL plans support free reissues. Reissuance can be useful when server settings, keys or certificate deployment details change.
Do I need OV or EV for a normal website?
Many standard websites can start with DV. Choose OV or EV when verified organization identity is an important requirement for the website or business.
Where can I get help choosing SSL?
Use the SSL Finder on this page or visit the NiceNIC Support Center for help with SSL selection and management.
