Do I Need an SSL Certificate?

Let’s Understand Why SSL Certificate is Mandatory?

Are you searching for an answer to this query- whether you require an SSL certificate for your website? Look no further! The answer you’ve been seeking is affirmative – you do indeed need an SSL certificate.

There are “n” reasons why you need an SSL certificate. Along with clarifying why, we will also answer some of your engaging questions, such as – Do I need SSL for my website? What type of SSL certificate do I need? and many more.

Why do we need an SSL certificate?

You need this certificate to keep your information in transmission – protected and confidential. In order to understand the answer to this query, let’s first go through the SSL certificate as in what it is. 

An SSL certificate can be regarded just like a security protocol or, to be more specific – a digital certificate. The certificate encrypts transmission between a web browser and a server. When a website visitor inputs an HTTPS URL, the browser establishes a secure connection with the server, guaranteeing that any data shared between the two is encrypted and fended from prying eyes.

Moreover, an SSL certificate goes beyond providing security. It can also foster trust and confidence with website visitors. Seeing the padlock icon or “https” prefix in the browser assures users that they are interacting with a legitimate and trustworthy website.

It’s easy to view the details of an SSL certificate by simply clicking on the padlock symbol located within the browser bar. The details contained within an SSL certificate include various pieces of information, such as:

  • The name of the main domain for which the certificate was issued
  • The person, organization, or device it was given to
  • The Certificate Authority that issued it
  • The list of associated subdomains (if any)
  • The certificate’s issue and expiry dates
  • The public key details

Do I need SSL for My website?

You can successfully protect the information stored on your system using an antivirus. But answer this – will you be able to ensure the online intake that is transmitted will be safe using an antivirus? The answer will be “No.” You may reply that I would use a firewall to prevent my system using predetermined security policies. Let me inform you – a firewall and an SSL certificate are two entirely different security mechanisms. A firewall protects and monitors data packets going in and out, but it can’t encrypt the information or data you enter on a website and send it to a server. For that purpose, you would need an SSL certificate.

Moreover, one of the most prevalent search engines – Google, has made it obligatory for websites to have an SSL certificate since 2014. Websites without SSL certificates are labeled as insecure, and because of this, websites can significantly lose traffic and prestige. Browsers like Chrome and Firefox have also initiated enforcing similar guidelines.

Why do we need SSL certificate? One of the other reasons is the Warning messages. Suppose your certificate has expired or the website in the first place needs one. In that case, the user will witness a forewarning stating that the site the user is trying to communicate with is not safe and may pose various risks. Once such a message comes in front of a user, they may leave the website instantly. No one will be foolish enough to share confidential information on a site that’s not secure. This scenario will lead to a loss of business or a decline in website traffic.

All that counts is that the website should have an active digital certificate. Without it, the data will be in plain text format, which hackers can easily access using man-in-the-middle or packet sniffing attacks. Hence, having a digital cert and keeping it up-to-date becomes crucial in ensuring website accessibility and user safety and staying competitive in the online marketplace.

In short, you do need an SSL as it:

  • Protects sensitive data sent between a user’s browser and a website’s server (Encryption)
  • Guards against cyber threats like hacking, phishing, and identity theft
  • Confirms a website’s originality and genuineness through the use of digital signatures (Authentication)
  • Builds trust with website visitors by showing a padlock icon or “https” prefix in the browser (Building Trust)
  • Helps websites comply with Google regulations and evade being labeled as insecure on popular browsers (Compliance regulation)

What type of SSL certificate do I need?

Which security certificate you should prefer depends upon your organization’s needs. Before understanding which certificate is best for which sort of organization, first understand the different types of SSL certificates available out there.
