What is an SSL certificate?

An SSL (Secure Sockets Layer) certificate, now mostly known as TLS (Transport Layer Security), is a digital certificate that verifies a website's identity and creates an encrypted, secure connection between a user's browser and the website's server, enabling HTTPS and protecting sensitive data like logins, credit card numbers, and personal info from eavesdropping, often shown as a padlock icon and "https://" in the URL.

What is the purpose of an SSL certificate?

SSL certificates are what enable websites to use HTTPS, which is more secure than HTTP. An SSL certificate is a data file hosted in a website's origin server. SSL certificates make SSL/TLS encryption possible, and they contain the website's public key and the website's identity, along with related information.

Is an SSL certificate necessary?

Yes, an SSL/TLS certificate is essential for virtually every modern website because browsers flag non-HTTPS sites as "Not Secure," eroding user trust, while search engines like Google favor secure sites, and encryption protects user data from eavesdropping and tampering. It's no longer just for e-commerce; it's a standard requirement for any site to function correctly and safely online, enabling HTTPS and creating a padlock icon.

Why is SSL no longer used?

SSL (Secure Sockets Layer) is obsolete because its older versions (SSL 2.0, SSL 3.0) contain critical, unfixable security flaws like POODLE, allowing attackers to decrypt data, and it lacks modern cryptographic strength, leading to its replacement by the much more secure and advanced TLS (Transport Layer Security), with TLS 1.2 and 1.3 being current standards. While the term "SSL" is still colloquially used, technically, any reliance on actual SSL protocols leaves systems vulnerable to major breaches, prompting organizations and browsers to phase it out completely for TLS.

Does anyone still use SSL?

In fact, most modern web browsers no longer support SSL at all. TLS is the up-to-date encryption protocol that is still being implemented online, even though many people still refer to it as "SSL encryption." This can be a source of confusion for someone shopping for security solutions.

Is SSL certificate free or paid?

Free SSL certificates are a great option for basic security needs, but they may lack additional features and support. Paid SSL certificates, on the other hand, offer a wider range of benefits, including enhanced security, faster website performance, and dedicated support.

What are the three types of SSL certificates?

There are three types of SSL Certificate available today; Extended Validation (EV SSL), Organization Validated (OV SSL) and Domain Validated (DV SSL).

How long is an SSL certificate valid?

SSL certificates expire at maximum 398 days from their issuance date, but most CAs will set their expiration date sooner, offentimes around 395 days. It is important to renew any of them BEFORE they expire. Waiting will cause serious disruptions for organizations and their customers.

How to tell if a site is using SSL?

You can check if the SSL certificate is active by visiting the website and looking for a padlock icon in the address bar. If it's there, the SSL is working. Also, you can use online tools like SSL Checker to confirm its status.

What is the safest browser to use?

There's no single "most secure" browser, as it depends on your needs, but top contenders for privacy and security include Brave (built-in ad/tracker blocking), Firefox (strong open-source privacy), DuckDuckGo (privacy-focused), and specialized options like Tor (maximum anonymity, slower) or LibreWolf (Firefox-based, minimal telemetry). For general users, Brave and Firefox offer great out-of-the-box protection, while Tor provides extreme anonymity at a performance cost.
 

What happens if you don't use SSL?

Phishing attacks.

When you don't use an SSL/TLS certificate on your site, you're not authenticating yourself. This leaves your brand open to being used in phishing attacks because users can't easily identify whether an imposter's phishing website is real or fake.
