What is SSL?
SSL known as Secure Socket Layer is a cryptographic technology which secures any sensitive data sent over a network. SSL prevents unauthorized persons from reading and modifying the transmitted data. It makes sure that any data transferred between two parties for example between a site and the user will remain impossible to read before reaching the destination. With the use of encryption algorithms on the data being transmitted, it prevents the hackers from intercepting the connection. TLS or Transport Layer Security is an updated, more secure version of SSL but it’s still referred as the most commonly used SSL. But when you get an SSL from Monovm fear not, it still means you are getting the most up-to date TLS certifications.
Before we go forward with the article, we would like to show you how Google Chrome displays websites without any SSL certification.
Visual proof of an SSL certificate
One of the best ways to check the websites authenticity depends on the visual cues of the SSL certification on a website. What are those visual cues and where to find them? As it is the most accepted standards of security, it will be displayed where everyone can see them and maybe even you encountered them without knowing it.
The first cue is on the address bar. The websites prefix will be https:// while without an SSL certification it will look like http://.
In the address bar you will see a big indication of safety, the presence of a padlock before the web address. This assures that the connection is encrypted and secure from both sides which eases the mind of users when making payments.
The Extended Validation SSL Certification (we will talk more about it below) when used on a website will display the company name in the address bar. This is the most secure form of certification proving to customers that it’s 100% legitimate.
For the final visual cue of SSL certification is a seal image which can be used on a site to display the brand of the SSL. This lets customers know the information is secure and protected which will lead to higher chances of transactions to take place.
After getting acquinted with the visual cues, lets move onto the levels of SSL certification.
- Domain validation SSL Certification
- These type of certifications needs proof of control over just the domain name. They do not check the identity of the organization as the certificate contains only the domain name supplied to the issuing authority. These SSLs are the most basic level of SSL and appropriate for test servers and internal links.
- Organization validation SSL Certification
- These type of certifications cannot be obtained by individuals but only businesses and organizations have the possibility. The reason is that it’s required to prove that the company is registered and legally accountable as a business while proving that they own the domain name. The certificate issued is the proof of domain and company name.
- Extended validation SSL Certification
- EV SSL requires both the validations for domain and company as well as many additional authentication steps which certifies that it is a registered company. The company information are then integrated into the certificate which users can access from the access bar. Using a EV SSL will display the company name in green on the address bar and this is a high visual sign of trust on the website when handling personal information.
