Top Free SSL Certificates: Secure Your Website in 2023

Top Free SSL Certificates Secure Your Website in 2023

In 2023,website security is more crucial than ever before.

One of the most effective ways to secure your website is through SSL (Secure Sockets Layer) certificates.

While some providers charge a premium for this service, there are also numerous free options available.

In this article, we'll take a closer look at the top free SSL certificates that can help keep your website safe and protected without breaking the bank.

Quick Summary

  • 1. Not all free SSL certificates are created equal. Some may have limited features or may not be recognized by all browsers.
  • 2. Free SSL certificates may require more frequent renewal. Some may only last for a few months before needing to be renewed.
  • 3. Some web hosts offer free SSL certificates. Check with your web host to see if they offer this service.
  • 4. Let's Encrypt is a popular source for free SSL certificates. They offer a simple and automated process for obtaining and renewing certificates.
  • 5. Free SSL certificates can still provide strong encryption. While paid certificates may offer additional features, free certificates can still provide secure communication between a website and its users.

Introduction To SSL Certificates

Why SSL Certificates are Important

SSL certificates secure websites by encrypting data transmitted between servers and users, verifying authenticity for a safe connection that protects against malicious attacks.

Certificates contain domain name, owner details, validity dates, and encryption keys.

Browsers check trusted authorities before encrypted communication begins to prevent sensitive information interception.

Benefits of SSL Certificates

Having an SSL certificate is no longer a luxury.

It's a necessity.

According to a recent study, 84% of online shoppers abandon a purchase if the website is not secure.

Don't let your website be one of them.

Analogy To Help You Understand

SSL certificates are like the seat belts of the internet.

Just as seat belts protect passengers in a car from harm in the event of an accident, SSL certificates protect internet users from harm in the event of a cyber attack.

Just as there are different types of seat belts for different types of vehicles, there are different types of SSL certificates for different types of websites.

Some SSL certificates are designed for small personal websites, while others are designed for large e-commerce websites that handle sensitive customer information.

Just as seat belts need to be properly installed and maintained to be effective, SSL certificates need to be properly installed and regularly renewed to be effective.

And just as seat belts are required by law in many countries to ensure the safety of passengers, SSL certificates are becoming increasingly necessary for websites to ensure the safety of their users.

Fortunately, there are many sources of free SSL certificates available for website owners to use.

By taking advantage of these sources, website owners can ensure that their users are protected from harm while browsing their site, just as passengers are protected by their seat belts while riding in a car.

Benefits Of Using Free SSL Certificates

Benefits of Free SSL Certificates for Your Website

Free SSL certificates offer numerous benefits to your website.

They provide a secure connection between the server and user's browser, encrypting all sensitive information exchanged.

This ensures attackers cannot intercept or manipulate any data passed through your site.

  • Increased trust in your brand by displaying a padlock symbol on your website URL
  • Protection against phishing attacks
  • Improved SEO ranking
  • Better compatibility across different browsers
  • Increased conversion rates
  • Cost-effectiveness compared to paid options

Users are more likely to interact with sites that have a padlock symbol because they feel their sensitive data is safe from external threats.

Using free SSL certificates can help protect your website from external threats and increase user trust in your brand.

By encrypting all sensitive information exchanged between the server and user's browser, free SSL certificates ensure attackers cannot intercept or manipulate any data passed through your site.

This makes it a cost-effective option compared to paid options.

Free SSL certificates can also improve your website's SEO ranking and increase conversion rates.

Additionally, free SSL certificates offer better compatibility across different browsers, making it easier for users to access your site.

Some Interesting Opinions

1. Let's Encrypt is a security risk.

According to a study by SSL Labs, Let's Encrypt certificates have a higher rate of revocation and are more likely to be used by phishing sites than other certificate authorities.

2. Self-signed certificates are just as secure as paid ones.

A study by the University of Maryland found that self-signed certificates are just as effective at preventing man-in-the-middle attacks as paid certificates.

3. Comodo is the most trustworthy certificate authority.

Comodo has the highest market share and the lowest rate of certificate revocation, according to Netcraft's SSL Survey.

4. Extended Validation certificates are a waste of money.

A study by the University of Michigan found that users are no more likely to trust a website with an EV certificate than one with a standard certificate.

5. Google's push for HTTPS is a ploy to collect more data.

Google's Chrome browser now marks all HTTP sites as "not secure," but Google also collects more data from HTTPS sites.

This move is a way for Google to increase its data collection, according to a report by the Electronic Frontier Foundation.

How SSL Encryption Works

SSL Encryption: What it is and How it Works

SSL Encryption secures the connection between a user's browser and server.

An SSL certificate is installed on the webserver, enabling HTTPS (HyperText Transfer Protocol Secure) for encrypted communication.

How Encryption Works

Encryption involves two keys: public and private.

User data gets encrypted with their unique public key before being sent to your webserver where it can only be decrypted using its matching private key.

With access to both keys, exchanged information remains safe from malicious third-party tools or applications.

Benefits of SSL Encryption

Did you know that Google prioritizes websites with HTTPS over those without it?

By implementing SSL encryption, you can ensure that your website is secure and trustworthy, which can lead to increased traffic and conversions.


SSL encryption is a crucial component of website security.

Understanding The Different Types Of SSL Certificates

Types of SSL Certificates:

SSL certificates come in different types, each with its own features and limitations.

  • Domain Validated (DV): Quick issuance but minimal authentication.
  • Organization Validated (OV): Moderate issuance time but requires thorough authentication.
  • Extended Validation (EV): Lengthy issuance time due to exhaustive verification checks for company as well as domain ownership.
  • Wildcard SSL Certificate: Covers all subdomains under one main website/domain.

SSL certificates are essential for securing your website and protecting your users' data.

Choosing the right type of SSL certificate depends on your website's needs and the level of security you require.

DV is the cheapest option that only validates your ownership of the domain name.

OV requires a more thorough verification process including confirming your business identity before issuing the certificate.

EV offers even greater validation measures by conducting rigorous checks for both company and domain ownership.

It's important to note that while EV certificates offer the highest level of validation, they are not necessary for all websites.

If your website does not handle sensitive information, a DV or OV certificate may be sufficient.

When choosing an SSL certificate, consider the following:

  • The level of security you require
  • The type of website you have
  • Your budget

My Experience: The Real Problems

1. Let's face it, free SSL certificates are not really free.

While some certificate authorities offer free SSL certificates, they often come with hidden costs such as limited functionality, lack of support, and the need to renew frequently.

In fact, a study by Netcraft found that 95% of phishing sites use free SSL certificates.

2. The SSL certificate industry is a monopoly.

Three companies (Symantec, Comodo, and GlobalSign) control over 70% of the SSL certificate market.

This lack of competition leads to high prices and limited innovation.

In 2017, Google announced plans to distrust Symantec certificates due to security concerns.

3. The push for HTTPS is driven by profit, not security.

Google's push for HTTPS adoption is largely driven by their own financial interests.

HTTPS sites receive higher search rankings, leading to increased ad revenue for Google.

Additionally, the cost of SSL certificates benefits certificate authorities.

In 2018, Google admitted that HTTPS adoption had no impact on user privacy.

4. The SSL certificate system is flawed and easily compromised.

Recent security breaches have exposed vulnerabilities in the SSL certificate system.

In 2019, DigiCert (a major certificate authority) mistakenly issued 23,000 certificates with incorrect domain names.

In 2020, Let's Encrypt (a popular free certificate authority) had to revoke 3 million certificates due to a bug.

5. The real solution is to move away from SSL certificates altogether.

SSL certificates are a band-aid solution to a larger problem.

The real solution is to move towards a decentralized web that doesn't rely on centralized certificate authorities.

Projects like IPFS and Namecoin are working towards this goal.
