Why Choose Comodo PositiveSSL?
- Hassle-free domain validation. Choose your preferred verification method: Email, HTTP Hash, or DNS CNAME. The automated process issues your certificate in approximately five minutes. No paperwork, no phone calls, no waiting for manual reviews. Domain Validation requires only proof that you own or control the domain, which is why it’s the fastest SSL validation type available.
- Secures both www and non-www versions. Comodo PositiveSSL is a single-domain certificate that covers both the www and non-www versions of your domain name. When a visitor types either version into their browser, they’ll see the HTTPS padlock icon confirming a secure connection.
- 99.3% browser compatibility. This certificate is trusted by virtually every browser on the market, including older versions. Install it on any web server or email client and your visitors will see the SSL padlock regardless of their device or platform. The chance of an SSL connection error is negligible.
- 256-bit encryption with a 2048-bit RSA key. The Comodo PositiveSSL certificate uses industry-standard 256-bit encryption and is signed with a 2048-bit RSA signature key, matching the cryptographic strength of certificates that cost several times more. ECC (Elliptic Curve Cryptography) is also supported for those who prefer modern key algorithms.
- $10,000 warranty. Sectigo backs this certificate with a $10,000 warranty that covers potential financial losses resulting from certificate misissuance. If a flaw in the certificate itself leads to a data breach, you’re protected. This is CA liability coverage, a safety net against mistakes on Sectigo’s end.
- Comodo Secure site seal. Every Comodo PositiveSSL certificate includes the Comodo Secure site seal, a visual trust badge you can place on your homepage, checkout page, or login area. It signals to visitors that your site has been verified and encrypted, which can improve their confidence and your conversion rates.
- Unlimited reissues and server licensing. Reissue your certificate free of charge whenever you need to, and install it on as many servers as required at no additional cost. With certificate lifespans decreasing to 200 days in 2026, the unlimited free reissues included with Comodo PositiveSSL make the transition seamless. No extra fees when it’s time to renew.

It’s one of the most popular SSL certificates in the world, consistently earning positive reviews from website owners who need reliable security at a low price.
Is Comodo PositiveSSL the same as Sectigo PositiveSSL?
Yes. Comodo CA rebranded to Sectigo in November 2018. The certificate itself, its encryption, root infrastructure, and features remain identical. You may see it listed as “Comodo PositiveSSL” or “Sectigo PositiveSSL” depending on the reseller, but it’s the same product issued by the same Certificate Authority.
How fast is Comodo PositiveSSL issued?
Approximately five minutes. Since this is a Domain Validation certificate, all you need to do is confirm domain ownership through one of three methods: Email, HTTP Hash, or DNS CNAME. There’s no business verification or paperwork involved.
What does the Comodo PositiveSSL certificate secure?
It secures a single domain name, covering both the www and non-www versions (e.g., yoursite.com and www.yoursite.com). It does not cover subdomains or additional domains. For those needs, see the PositiveSSL Wildcard or PositiveSSL Multi-Domain.
Where can I buy Comodo PositiveSSL?
You can purchase Comodo PositiveSSL directly from this page. Select your preferred subscription length, complete checkout, and you’ll receive your certificate files after passing domain validation. The entire process takes under ten minutes.
Does Comodo PositiveSSL work with certificate automation (ACME)?
Yes. You can use ACME-compatible tools to automate issuance, installation, and renewal. This is especially useful as maximum certificate lifespans decrease to 200 days in March 2026 and continue shortening to 47 days by 2029.
