An SSL certificate is a digital certificate that authenticates a website’s identity and enables an encrypted connection. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser.
Companies and organizations need to add SSL certificates to their websites to secure online transactions and keep customer information private and secure.
Websites need SSL certificates to keep user data secure, verify ownership of the website, prevent attackers from creating a fake version of the site, and convey trust to users.
If a website is asking users to sign in, enter personal details such as their credit card numbers, or view confidential information such as health benefits or financial information, then it is essential to keep the data confidential. SSL certificates help keep online interactions private and assure users that the website is authentic and safe to share private information with.
More relevant to businesses is the fact that an SSL certificate is required for an HTTPS web address. HTTPS is the secure form of HTTP, which means that HTTPS websites have their traffic encrypted by SSL. Most browsers tag HTTP sites – those without SSL certificates – as “not secure.” This sends a clear signal to users that the site may not be trustworthy – incentivizing businesses who have not done so to migrate to HTTPS.
SSL certificates can be obtained directly from a Certificate Authority (CA). Certificate Authorities – sometimes also referred to as Certification Authorities – issue millions of SSL certificates each year. They play a critical role in how the internet operates and how transparent, trusted interactions can occur online.
The cost of an SSL certificate can range from free to hundreds of dollars, depending on the level of security you require. Once you decide on the type of certificate you require, you can then look for Certificate Issuers, which offer SSLs at the level you require.
Obtaining your SSL involves the following steps:
Prepare by getting your server set up and ensuring your WHOIS record is updated and matches what you are submitting to the Certificate Authority (it needs to show the correct company name and address, etc.)
Generating a Certificate Signing Request (CSR) on your server. This is an action your hosting company can assist with.
Submitting this to the Certificate Authority to validate your domain and company details
Installing the certificate they provide once the process is complete.
Once obtained, you need to configure the certificate on your web host or on your own servers if you host the website yourself.
How quickly you receive your certificate depends on what type of certificate you get and which certificate provider you procure it from. Each level of validation takes a different length of time to complete. A simple Domain Validation SSL certificate can be issued within minutes of being ordered, whereas Extended Validation can take as long as a full week.
