FAQ

Frequently asked questions

Quick answers to the most common SSL questions.

What is an SSL certificate and do I really need one?

An SSL certificate encrypts data between your website and visitors’ browsers, protecting sensitive information like passwords and credit card numbers. Yes – every website needs one. Browsers now flag sites without SSL as “Not Secure,” which hurts trust and SEO rankings.

What's the difference between free and paid SSL certificates?

Free certificates (like Let’s Encrypt) provide basic domain validation and encryption. Paid certificates offer higher validation levels (OV/EV), warranty protection, dedicated support, and additional trust signals like company name verification. For ecommerce or business sites, paid certificates are typically recommended.

How long does it take to get an SSL certificate?

Domain Validated (DV) certificates can be issued in minutes. Organization Validated (OV) certificates typically take 1–3 business days as they verify your business details. Extended Validation (EV) certificates require the most thorough vetting and usually take 1–5 business days.

What happens when my SSL certificate expires?

When your SSL certificate expires, browsers will display a warning page telling visitors the site is not secure. This can dramatically reduce traffic and trust. Most providers offer auto-renewal, and our Certificate Monitor tool can alert you before expiration.

Do I need a wildcard or multi-domain certificate?

A wildcard certificate secures your main domain and all its subdomains (e.g., *.example.com). A multi-domain (SAN) certificate secures multiple different domains. Choose wildcard if you have many subdomains; choose multi-domain if you run several distinct websites.

Is SSL the same as TLS?

TLS (Transport Layer Security) is the successor to SSL (Secure Sockets Layer). While people still say “SSL” colloquially, modern secure connections actually use TLS 1.2 or 1.3. When you buy an “SSL certificate,” it works with the latest TLS protocols.
