These certificates use a stand of PKI (Public Key Infrastructure) to make sure sensitive information stays secure online. But what is an X.509 Certificate, and how does it actually keep the web safe? To prevent Phishing attacks and make the most out of your website security, here’s what you need to know.

What is an X.509 Certificate?

TLS/SSL Certificates were originally invented when the web was young. In 1988, the first standard for X.509 public key certificates was invented to help read and authorize certificate holders across the web. An X.509, or TLS/SSL X.509 certificate, is used to create a secure “handshake” between by pairing a public key to an owner. This way, TLS/SSL Certificates can’t be used to redirect or misdirect a user to a copycat website, fake a digital signature, or steal encrypted information.

Who Needs One?

Ideally, all websites would require an X.509 certificate to authenticate a connection. For websites that are protected by TLS/SSL Certificates, the moment an X.509 Certificate expires, the page displays an error message to warn users that they’re no longer on safe ground. This can help prevent Phishing attacks and other scams that exist to trick users into entering private information into an unsecured portal.

How Does It Enhance Website Security?

While some web features, like the HTTPS function that lets users know they’re visiting a safe, supported site, helps initiate extra online security, TLS/SSL Certificates go one step further by assigning roles to users to make sure that no information slips into the wrong hands. By creating pairs and bonding users with specific keys, X.509 Certificates authenticate the connection between a user and a secure site. You can use X.509 Certificates to create digital signatures, authenticate a connection, or share sensitive information online, such as credit card or social security numbers, without fear of them becoming public, shared info. If you’ve ever made a purchase online, signed a document, or accessed a remote server simply by singing into a website, you’ve benefited from the many uses of an X.509 Certificate.

That’s not all: An X.509 Certificate also helps provide extra layers of security online, using secure features like Client Authentication and Code Signing to make sure no unauthorized users can hack into your space and steal private information. If Website security is your top concern--and it should be--getting an X.509 Certificate is crucial to the safety of your business.
