Comodo DV SSL Features
- Encryption. 256-bit symmetric encryption with a 2048-bit RSA signature key. This is the same encryption standard used across all commercial SSL/TLS certificates, ensuring data transmitted between your server and visitors’ browsers remains private.
- Validation. Domain validation only, with no business vetting or paperwork required. The CA verifies that you control the domain through one of three methods: email approval, HTTP/file hash, or DNS CNAME record. The entire process is automated and typically completes within minutes.
- Domain Coverage. This is a DV single domain certificate, securing one fully qualified domain name including both the www and non-www versions (e.g., example.com and www.example.com). This certificate does not support subdomains or additional domains. If you need to cover subdomains, consider a wildcard SSL certificate.
- Browser Compatibility. 99.3% recognition across all major browsers, mobile devices, servers, and email clients. Visitors on older browser versions will still see the secure padlock indicator without compatibility issues.
- Site Seal. Includes the Comodo Secure site seal, a visual trust badge you can place on your homepage, checkout page, or anywhere visitors need reassurance that the connection is protected.
- Warranty. Backed by a $500,000 warranty that covers end-user damages in the unlikely event of a data breach caused by certificate mis-issuance on Sectigo’s end. This is significantly higher than the $50,000 warranty on PositiveSSL or the $10,000 warranty on EssentialSSL.
- Server Licensing. Unlimited server installs at no additional cost. If you host your site across multiple servers or use a load balancer, you can install this certificate on every server without purchasing additional licenses.
- Reissues. Unlimited free reissues throughout the life of your subscription. If you need to regenerate your certificate after a CSR change, server migration, or private key compromise, you can reissue at any time.
- Certificate Lifespan. As of March 15, 2026, the CA/Browser Forum’s revised rules cap SSL/TLS certificate validity at 200 days per issuance (down from the previous 397-day maximum). Multi-year subscriptions at SSL Dragon lock in your price for the full subscription term. You’ll receive a reminder before each expiry, and reissuing is free and takes only a few minutes.
Why Choose Comodo DV SSL
The Comodo brand carries one of the strongest trust signals in the SSL industry. Founded in 1998, Comodo grew to become the world’s largest certificate authority before its CA division was acquired by Francisco Partners in 2017 and rebranded as Sectigo in November 2018. Despite the corporate change, the Comodo product line lives on. Certificates sold under the Comodo name are issued by Sectigo’s trusted root, recognized by 99.3% of browsers and devices worldwide.
What sets the Comodo DV SSL apart from other Comodo domain validation products is its warranty. While PositiveSSL offers the lowest entry price with a $50,000 warranty, and EssentialSSL provides $10,000, Comodo DV SSL delivers $500,000 in coverage. For buyers who want the strongest financial protection available at the DV level without the cost and wait time of organization validation or extended validation, this is the certificate to choose.
Best suited for: blogs, personal sites, portfolios, startups, landing pages, small business websites, and any single-domain project that needs reliable encryption and a recognized trust seal without business vetting.
Consider alternatives if: you run an e-commerce site processing transactions (OV or EV certificates display verified business identity), you need to secure subdomains (choose a wildcard certificate), or you manage multiple separate domains (choose a multi-domain certificate).
Frequently Asked Questions
What is a Comodo domain validation certificate?
A Comodo domain validation SSL certificate encrypts the connection between your website and its visitors after verifying only that you control the domain. Unlike organization validation (OV) or extended validation (EV) certificates, it does not authenticate your business identity. Comodo offers several DV products at different price and warranty tiers, including PositiveSSL, EssentialSSL, and the Comodo DV SSL covered on this page.
How long does it take to get a Comodo DV SSL certificate?
Typically under five minutes. Once you complete your purchase and submit a certificate signing request (CSR), the CA sends a validation prompt through your chosen method (email, HTTP file, or DNS CNAME). As soon as you approve it, the certificate files are issued and delivered to your inbox. There is no manual review, phone call, or paperwork involved.
What’s the difference between Comodo DV SSL and PositiveSSL?
Both are domain validation certificates issued by Sectigo under the Comodo brand. They provide the same encryption strength (256-bit) and the same browser compatibility (99.3%). The primary differences are warranty coverage and price. PositiveSSL is the budget option with a $50,000 warranty, while the Comodo SSL DV certificate carries a $500,000 warranty at a higher price point. If warranty size matters to you or your clients, Comodo DV SSL is the stronger choice. If you’re optimizing purely for cost, PositiveSSL will do the job.
Is Comodo the same as Sectigo?
Not exactly. Comodo Group founded its certificate authority business in 1998. In 2017, the CA division was sold to Francisco Partners and rebranded as Sectigo in November 2018. The Comodo brand continues as a product line within Sectigo’s portfolio. When you buy a Comodo SSL certificate today, Sectigo is the issuing CA. The root certificates, validation infrastructure, and trust chain are all Sectigo’s, while the Comodo name serves as the product brand.
How long is the Comodo DV SSL certificate valid?
Under current CA/Browser Forum rules (effective March 15, 2026), each SSL/TLS certificate issuance is valid for a maximum of 200 days. This applies to all publicly trusted certificates regardless of brand or validation level. If you purchase a multi-year subscription at SSL Dragon, your price is locked in for the full term. You simply reissue the certificate before each 200-day expiry (free of charge), and we send reminders 30 days in advance. The maximum validity will continue to decrease in the coming years: 100 days by March 2027, and 47 days by March 2029.
