Why is SSL Certificate Important?

SSL (Secure Sockets Layer) encrypts data traffic between your website and visitors. Google marks sites without SSL as "Not Secure" and penalizes them in search rankings (SEO). It is mandatory for e-commerce sites.

DV vs OV vs EV Certificates

**DV (Domain Validation):** Verifies domain ownership only, issued in minutes. (Let's Encrypt, etc.)
**OV (Organization Validation):** Verified with company documents, offers medium trust.
**EV (Extended Validation):** Highest level, displays company name in the browser bar.

What happens if it expires?

The moment a certificate expires, browsers show a massive red warning screen ("Your connection is not private") to visitors. This leads to 90% traffic loss and damages brand reputation.

SSL FAQ

Is Let's Encrypt secure?
Yes, technically it provides the same 256-bit encryption as paid certificates. The only difference is it's issued for 90 days and needs auto-renewal. Paid certs are usually valid for 1 year and include warranty.
What is Wildcard SSL?
Wildcard SSL protects a domain and all its subdomains with a single certificate. For example, `*.diyovm.com` covers both `blog.diyovm.com` and `mail.diyovm.com`.
