Free vs paid SSL certificate: what to choose in 2026

For most websites a free SSL certificate (Let's Encrypt) is enough, because the encryption is identical to a paid one. You pay only when you need your company's identity validated (OV or EV), a financial warranty, or a Wildcard that's easier to manage. Without SSL, browsers show a "Not secure" warning, visitors leave and Google ranks you lower, so below is what you get for free, what you get for money, and how to choose.

What is an SSL certificate, in short

An SSL certificate (technically TLS) does two things for your site:

• It encrypts traffic: data between the visitor and the server (passwords, cards, forms) travels encrypted and can't be read by anyone intercepting the connection.
• It confirms identity: the certificate shows the visitor is talking to your actual server, not an impostor.

In practice, SSL turns "http://" into "https://" and shows the padlock in the browser. Without it, browsers mark the site as not secure, forms become risky, and your Google ranking suffers: HTTPS has been a ranking signal for years.

The free SSL certificate: Let's Encrypt

Let's Encrypt is a non-profit certificate authority that issues free SSL certificates trusted by all modern browsers. What you should know:

• The encryption is the same: a free certificate uses the same algorithms as a paid one. The padlock looks the same and the connection is just as secure.
• DV-type validation: Let's Encrypt only checks that you control the domain, not who the company is.
• Short validity, automatic renewal: certificates expire after 90 days, but with a good provider renewal happens automatically, with nothing for you to do.
• No financial warranty: paid certificates come with insurance (a warranty) in case the certificate authority makes a mistake; free ones don't.

Paid certificates: DV, OV, EV and Wildcard

The difference between certificates isn't the encryption but the validation level and a few extras:

• DV (Domain Validation): validates only the domain, like Let's Encrypt. The paid version adds a financial warranty and longer validity, but technically it's the same.
• OV (Organization Validation): the authority also checks that your company legally exists. Company details appear in the certificate, a trust signal for B2B customers.
• EV (Extended Validation): the strictest company check. Mostly used by banks and financial institutions.
• Wildcard: one certificate for a domain and all its subdomains (site.ro, mail.site.ro, shop.site.ro). Free versions exist, but paid ones are often easier to manage.

When a free SSL certificate is enough

In most cases. A free certificate with automatic renewal covers:

• Brochure sites and blogs: encryption is complete, the padlock shows, and for Google all that matters is that you have HTTPS.
• Small and mid-sized online shops: payments go through processors (Stripe, PayPal) with their own security anyway, and the DV certificate encrypts the rest of the traffic.
• Web applications and APIs: encryption is what matters, and extended validation adds nothing technical.
• Personal projects and test sites: there's no point paying.

When a paid certificate is worth it

There are cases where the cost makes sense:

• Financial institutions and large companies: OV/EV validation proves the organization's legal identity, and auditors and partners may ask for it explicitly.
• B2B with large contracts: when your clients run due diligence, an OV certificate showing your company name adds legitimacy.
• The financial warranty: if internal policy or your insurer requires a warranty on the certificate, only paid ones have it.
• Infrastructure with many subdomains: a Wildcard or multi-domain (SAN) certificate managed centrally makes administration simpler.

A paid certificate does not give you more speed, better encryption or better SEO. Google treats HTTPS the same whoever issued the certificate.

How to install an SSL certificate (included at BTU)

With a current provider, you don't install anything by hand:

• On BTU hosting: the SSL certificate is issued and installed automatically for each domain, and the 90-day renewal happens on its own. You only check that the site opens on https:// and that the redirect from http:// is active.
• Paid certificate: you generate a signing request (CSR), go through the certificate authority's validation, then upload the certificate in the control panel. The support team helps at each step.
• After installation: test the site with an online SSL checker and make sure every resource (images, scripts) loads over HTTPS, to avoid "mixed content" warnings.

You'll find the available options on our SSL certificates page.

Free for encryption, paid for validation

The encryption is identical, so a free SSL certificate is the right choice for the great majority of websites. You pay only when you need company validation (OV/EV), a financial warranty or easy management for many subdomains.

At BTU, every web hosting plan includes free SSL, installed and renewed automatically, with no setup and no expiry to worry about. If your business needs an OV, EV or Wildcard certificate, we'll tell you plainly which option fits.
