When it comes to securing a website, the name “Comodo” has been a dominant force for years. Website owners and developers worldwide have relied on Comodo certificates to provide the encryption and authentication needed to build a safe and trustworthy online environment. Even after a significant rebranding, the legacy and power associated with the Comodo name continue to make it a go-to choice for digital security.
But what exactly are Comodo certificates, and why do they remain so popular? This guide will explore the history of the brand, the different types of certificates available, their powerful technical features, and how they help build the user trust that is essential for online success.
The Comodo and Sectigo Connection Explained
One of the most common points of confusion for newcomers is the relationship between Comodo and Sectigo. In 2018, the Certificate Authority (CA) division of the Comodo Group was acquired and rebranded as Sectigo. While the parent company is now Sectigo, the product line itself was so iconic and well-regarded that the brand names, including “Comodo,” were retained.
So, when you purchase Comodo certificates today, you are actually buying a product from Sectigo, the world’s largest commercial Certificate Authority. This means you get the best of both worlds: the trusted legacy of the Comodo brand name combined with the robust, modern infrastructure of a global security leader. This backing ensures that every certificate meets the highest industry standards for security and reliability.
The Core Function: Encryption and Trust
At its heart, any SSL/TLS certificate, including those from Comodo, has two primary jobs: encryption and authentication. The moment a visitor lands on a site secured with a Comodo certificate, a secure, encrypted connection is established between their browser and the web server.
This process is powered by industry-leading technology:
- 256-bit Symmetric Encryption: This is the level of encryption used by banks and financial institutions to protect sensitive data. It scrambles all information—passwords, personal details, and payment information—into an unreadable format, making it useless to hackers who might intercept it.
- 2048-bit RSA Signature: This powerful signature key is used to authenticate the server’s identity, ensuring that your visitors are connected to your genuine website and not a phishing imposter.
- Universal Browser Compatibility: Comodo certificates are recognized by over 99.9% of all desktop and mobile browsers. This means your visitors will have a seamless, error-free experience, regardless of the device or browser they use.
Choosing the Right Validation Level
Comodo certificates come in three main validation levels. The one you choose depends on your business needs, budget, and the level of trust you want to convey to your audience.
1. Domain Validation (DV) Certificates
DV certificates are the fastest and most affordable way to secure a website. The Certificate Authority only verifies that the applicant has administrative control of the domain name. This process is fully automated and can be completed in minutes.
- Who it’s for: Blogs, personal portfolios, and informational sites that don’t collect highly sensitive user data.
- Trust Signal: Provides the essential HTTPS padlock, signaling that the connection is encrypted.
- Popular Product: Comodo PositiveSSL is a well-known DV certificate.
2. Organization Validation (OV) Certificates
An OV certificate offers a significant step up in trust. In addition to verifying domain ownership, the CA performs a light background check on your business. They verify its legal name, location, and registration status.
- Who it’s for: Corporate websites, non-profits, and small e-commerce stores that want to prove they are a legitimate registered entity.
- Trust Signal: The verified company name is displayed in the certificate details, providing visitors with an extra layer of assurance.
3. Extended Validation (EV) Certificates
EV certificates provide the highest level of trust and assurance available. The CA conducts a strict and comprehensive vetting process according to industry-wide standards, confirming your company’s legal, physical, and operational existence.
- Who it’s for: Banks, financial institutions, large e-commerce platforms, and any organization where maximum user trust is critical.
- Trust Signal: While modern browsers have moved away from the prominent “green bar,” clicking the padlock reveals detailed, verified company information, offering the ultimate proof of identity.
Building Trust with the Comodo Site Seal
Beyond the technical security, Comodo certificates offer a powerful psychological tool: the site seal. This is a visual logo that you can place on your website—often in the footer, on login pages, or during the checkout process.
The Comodo Secure Seal is more than just a decorative image. It acts as a constant, visible reminder to your visitors that they are on a secure and verified site. This simple badge can have a measurable impact on your business by:
- Reducing Shopping Cart Abandonment: For e-commerce sites, a trust seal can reassure customers at the critical moment they are about to enter their payment information.
- Increasing Conversions: When users feel safe, they are more likely to complete a desired action, whether it’s filling out a contact form, signing up for a newsletter, or making a purchase.
- Enhancing Brand Legitimacy: Aligning your website with a globally recognized cybersecurity brand like Comodo lends credibility to your own business.
Conclusion: A Legacy of Trusted Security
The decision to install an SSL certificate is one of the most important you will make for your website. It protects your customers, defends your brand’s reputation, and is essential for modern SEO.
