All about SSL certificates: Protection and trust on the web
Have you ever wondered what ensures that the information you send through a website doesn't fall into the wrong hands? That guarantee comes from a crucial system: SSL Certificates. Without it, data can be exposed to risks, leaving both users and companies that handle sensitive information vulnerable.
What is an SSL Certificate and why is it important?
An SSL (Secure Sockets Layer) Certificate is a technology that encrypts information between a web server and the user's browser. This process converts the data into code that is unreadable by any third party attempting to intercept the communication. When a website has a valid SSL Certificate, you'll see a small padlock in the address bar and the prefix "https://" instead of "http://," indicating that the connection is secure.
The importance of having an SSL Certificate is that, without this protection system, personal data, such as passwords, credit card numbers, or even email addresses, can be vulnerable to hacker attacks. In addition to security, SSL also improves user trust. Today, browsers mark sites without SSL as "unsafe," which can discourage visitors from visiting your site, affecting your brand's reputation and, in many cases, decreasing sales or interactions.
Implementing SSL Certificates: A Simple and Essential Step
Implementing an SSL Certificate on your website isn't as complicated as it seems. SSL providers offer a variety of options to suit different types of sites, from personal blogs to online stores. Most hosting providers already integrate this functionality into their services, making the task even easier. Once installed, the certificate automatically establishes a secure connection with users, protecting the information transmitted.
The implementation process includes three main phases: purchasing or acquiring a certificate, installing it on the web server, and configuring all pages on the site to use the HTTPS protocol. If you have any questions, there are support services, such as those offered by Exeditec, that specialize in ensuring the correct implementation and maintenance of SSL certificates.
Security and Quality: How to Choose a Good SSL Certificate?
Not all SSL Certificates are created equal. There are several types of certificates, such as Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV). The simplest, such as DV, simply ensure that the domain owner has proven their control over it, while EV certificates offer the most comprehensive validation, displaying the green bar and company name in the browser, adding an extra level of trust.
The quality of an SSL Certificate is also measured by the level of encryption. Currently, most certificates use 256-bit encryption, considered the highest security standard. However, beyond the type of certificate, the most important thing is that it is current and issued by a trusted Certificate Authority (CA). Otherwise, the browser could warn users that the site is not secure, even if some form of SSL is installed.
What happens if a website doesn't have an SSL certificate?
The lack of an SSL certificate can have serious consequences for any website. Without an SSL certificate, data sent between the browser and the server can be intercepted by hackers, which can result in information theft. This not only puts users at risk but can also lead to a massive loss of trust in your brand.
In addition, search engines like Google prioritize sites that use SSL. This means that if you don't have one, your site could appear lower in search results, affecting web traffic. Also, as mentioned before, browsers label sites without SSL as "insecure," which can scare visitors away and cause them to leave the page immediately.
Tips to keep your SSL Certificate up to date
An SSL Certificate isn't a system you install once and forget about. It's important to keep up with its renewal, as most certificates expire every one or two years. Additionally, if you make significant changes to your site, such as migrating to a new server, it's crucial to verify that the certificate is properly installed and working.
Another important aspect is to ensure that all website pages, including subdomains, use HTTPS. This can be achieved through proper server configuration and using permanent HTTP-to-HTTPS redirects.
