How to secure your website? Comprehensive Guide for Securing Your Website

SSL (Secure Socket Layer) is widely used on the internet, and it is very important for an e-commerce website and other sites that collect personal information. When you see the “https://” prefix in a website’s address, it means that the site is using SSL and here the ‘s’ stands for ‘secure’.

There are some more factors about SSL that you must know to get your website secured. You will understand everything after reading this blog.

What is SSL?

SSL stands for Secure Socket Layer. It is a security protocol that provides security to the data that is transferred between web browser and server. Netscape formally introduced the SSL protocol in 1995, making it the first widely used protocol for securing online transactions between consumers and businesses. 

This encryption is necessary to secure and protect sensitive information such as personal details like names and addresses of individuals or financial information like credit card numbers, when it is being transmitted over the internet.

Moreover, SSL also uses a digital certificate to verify the identity of the server which ensures that the client is connecting to the correct server and not a malicious imposter.

Why do you need an SSL certificate?

An SSL certificate is necessary for securing sensitive data and websites. It provides authentication, encrypts data, and enhances trust. Having an SSL certificate helps websites to verify its identity. Plus, it ensures users that they are interacting with the legitimate site.

It is essential to keep the data confidential when a website asks users to sign up or sign in, enter personal details such as credit card numbers, or view personal information like health benefits or financial transactions. SSL certificate ensures that the interactions are private and the website is authentic and safe to share some personal information. Websites with SSL certificates display a padlock icon, signalling a secure connection and instilling trust in visitors.

Additionally, SSL certificates also help to improve search engine rankings and compliance with data protection regulations. Ultimately, an SSL certificate is vital for websites that handle sensitive information, prioritize security, and seek to provide a safe and trustworthy online experience for their users.

SSL certificate is required for an HTTPS web address as HTTPS is the secure form of HTTP, which means that HTTPS websites have their traffic encrypted by SSL.

Types of SSL certificate

There are various types of SSL certificates but with different validation levels. Here are the main six types of it. 

  • Extended Validation Certificates (EV SSL) 

Extended Validation Certificates (EV SSL) are a type of SSL certificate which is the highest-ranking and most expensive one. It tends to be used for high profile websites which collect data and involve online payments. They are issued by a trusted certificate authority (CA) following a stringent verification process to confirm the identity and legitimacy of the website owner. 

EV SSL certificates have a green address bar and display the organization’s name in the user’s browser, which ensures users that the website is secure and trustworthy and provides stronger encryption, undergo extended validation processes and enhances overall security.

As they have strong security features, EV SSL certificates are recommended for websites that handle sensitive information, like credit card numbers or personal data. 

  • Organization Validated certificates (OV SSL)

OV SSL certificates tend to be the second most expensive certificate (after EV SSLs), and their primary purpose is to encrypt the user’s sensitive information during transactions and has a similar assurance level to the EV SSL certificate. It displays the organization’s name and location, building trust with users.

OV SSL certificates offer higher security that makes them suitable for e-commerce, online banking, and government websites. Moreover, having benefits like increased trust, enhanced security, improved search engine rankings, and compliance with industry standards such as PCI DSS are a valuable investment for businesses seeking to protect their websites and sensitive data while establishing credibility with users.

  • Domain Validated certificates (DV SSL)

Domain Validated DV SSL certificates are basic, cost-effective options for securing websites that don’t handle sensitive data and tend to be used for blogs or informational websites. It provides lower assurance and minimal encryption as the validation process to obtain this SSL certificate type is minimal which is issued quickly and affordably, based solely on domain ownership.

Additionally, DV SSL certificates are fit for those who are not yet ready for a higher investment. Plus, it is easy to obtain and install. They lack the robust validation and security of other SSL certificate types. 

The browser address bar only displays HTTPS and a padlock with no business name displayed.

  • Wildcard SSL certificates

Wildcard SSL certificates secure a base domain and unlimited sub-domains under a single certificate. They are cost-effective and time-saving for websites with many subdomains and eliminating the need to manage multiple certificates. 

For example, if you bought a Wildcard for, it could be applied to and You can go with this option as this is less expensive than buying individual SSL certificates for a number or domains.

This is one of the most valuable tools for protecting websites with numerous subdomains from security threats.

  • Multi-Domain SSL Certificate (MDC)

Multi-Domain SSL Certificate (MDC) secures multiple domains and subdomains under a single certificate, offering cost-effective and streamlined security. This includes the combination of completely unique domains and subdomains with different TLDs (Top-Level Domains) except for local/internal ones.

Multi-domain SSL certificates cover up to 100 domain names. If you need to alter the names in any way, you can do that with the Subject Alternative Name (SAN) option. Some examples of Multi-Domain names you can use are:,,, and

  • Single Domain SSL Certificate

A single domain SSL certificate protects one domain and you can’t use this certificate to protect subdomains or a completely different domain. 

Single domain SSL certificates are commonly used for personal websites, blogs, small business websites, and other online platforms that operate under a single domain name with the help of a web design company in Brampton you can secure your website easily.
