What SSL does

An SSL certificate encrypts all information transmitted to and from your website, ensuring it is protected from third parties attempting to access it.

Why you need SSL

Browsers, like Google Chrome, mark pages without SSL encryption as not secure. This can have a negative effect on the trustworthiness of your website. If you have an SSL certificate, your site's URL will start with the prefix "https" and a padlock icon will be displayed in the browser bar, showing your visitors your site is secure and their data is safe. Pages that are protected with SSL receive better search engine rankings, and are more likely to be trusted by visitors.

SSL vs TLS

TLS is an updated, more secure version of SSL. When you buy an SSL certificate from IONOS, you get the latest TLS technology. We still refer to them as SSL certificates because it's the more common term.

Types of SSL/TLS certificates

Domain Validated (DV)

If you are just starting out, or want to use the SSL certificate in order to secure your personal website or blog, then usually the Domain Validated SSL (DV) will suffice. This way, all traffic is encrypted but no further validation is conducted. DV certificates are the right solution for simple websites like blogs, personal websites, and simple one-page websites. Do not use a DV SSL certificate for eCommerce or other applications which require a higher level of trust.

Organization Validated (OV)

If you are doing any business online you should at least use an OV SSL. When you're handling any kind of customer data, organization validation (OV) will make sure that the certificate is really from your organization, and that the domain belongs to you, not a third party. This helps you to protect your business and customers from phishing websites. Organization validation is a great way to secure a company website, a forum, or any other website with a login page that does not transfer payment data. Customers' usernames and passwords will be transferred with end-to-end encryption.

Extended Validation (EV)

If you want to convey the highest level of security and trustworthiness on your website, choose an extended validation certificate. EV is a must for eCommerce websites as it's the only kind of SSL certificate that guarantees the real origin of a website and the safety of payment information. That's why banks, big eCommerce organizations and government agencies rely on extended validation certificates.

Benefits of an SSL/TLS certificate

Protect your data transactions

SSL secures the browser connection between visitors and your website with up to 256-bit encryption. This means all transmitted data is protected from third parties attempting to access it.

Anti-phishing

You can protect your site against phishing (attempting to gain sensitive data from usernames) with SSL Business/Premium. Not only will our partner DigiCert check that your company owns and has the right to use the domain, but also that your company is registered and in good standing.

You want your visitors to feel confident that you are protecting the information they submit on your website. DigiCert is a global leader in internet security, meaning you have leading SSL security standards at your fingertips.
