Why SSL Certificates Alone Won’t Secure Your Website

Many website owners assume that an SSL certificate is an all-in-one website security solution. However, it’s only one part of the puzzle that makes up a secure site. Only relying on SSL leaves your site vulnerable to a wide range of threats. In this article, we’re going to break down exactly what SSL certificates are, what they can and can’t do, and what else you need to think about to keep your website secure.

What Is An SSL Certificate?

SSL stands for Secure Sockets Layer. It’s a digital certificate that authenticates a website’s identity. It also enables communication between the user’s browser and the website server to be encrypted. This prevents interception, so the data that’s shared between the browser and website is secure and private.

You can identify a website with an SSL certificate by checking the URL. If it begins with https, it’s secure. If it begins with http, it is not secured. You may also note that in some browsers a padlock appears in the address bar.

You want your website and any website you interact with to be secure, otherwise the information you share could be accessed during transmission. This could be anything from your personal details to your login credentials or your bank account information. Therefore, it’s very important to verify a website is secure before interacting with it.

What SSL Can’t Do

SSL is a must-have for any modern website, but it’s important to understand its limitations. SSL only encrypts the connection between the website’s server and the user’s browser. It can’t secure anything on the actual website content, the user’s browser or the server. That means that SSL can’t protect against threats like malware, brute-force login attempts or vulnerabilities in outdated plugins. It also won’t stop attackers from uploading malicious files or exploiting insecure themes.

What SSL Can’t Do

A safe website requires a multi-pronged approach to security. This starts with ensuring your CMS, plugins and themes are up to date. Many attackers will target known vulnerabilities in software, so if you neglect your updates you may leave your website open to harm.

Secure hosting also plays a major role. A good hosting provider will offer features like automatic backups, malware detection and DDoS protection. You can also activate features on your website yourself to limit user permissions, run regular security scans and enable a firewall which filters out malicious traffic before it reaches your site.

The Padlock Problem

For users, it’s important to know that a website with an SSL certificate is not trustworthy by default. The connection between your browser and their hosting may be secure, but the content of the website may not be. You should still exercise caution when entering your private details into unknown websites. Cybercriminals know that the padlock symbol builds trust with users, and so they exploit it. SSL certificates, HTTPS and the padlock symbol should be viewed as the baseline for trust – not the be all and end all.

Security For E-Commerce & Online Transactions

If your site handles financial data or sensitive personal information, the stakes are even higher. As well as your SSL certificate, you should also implement secure payment gateways, PCI compliance and vulnerability scanning. Your customer’s account details should be encrypted and secure, and any plugins you use to enable online payments should be trustworthy, up to date and secure.

Wrapping Up The Importance Of SSL Security

SSL is an essential building block of web security, but it’s not enough on its own. Think of it as locking the door to your website. It helps, but it doesn’t mean no one will try the windows. A layered approach to security gives you the best chance of keeping your site – and your users – safe.
