FAQ

What is an SSL certificate?

An SSL/TLS certificate is a digital certificate that authenticates a website's identity and enables encrypted HTTPS connections. All modern websites should use HTTPS.

What happens when an SSL certificate expires?

Browsers show a security warning blocking users from accessing the site. It also causes search ranking drops and breaks API connections.

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

DV (Domain Validation) verifies domain ownership only — cheapest and fastest. OV (Organization Validation) verifies the organization. EV (Extended Validation) provides the highest level of trust — used by banks.
