In today’s web landscape, where companies, startups, and IT agencies operate multiple websites or subdomains, the Comodo Multi‑Domain SSL (also known as SAN certificate) is an efficient and optimal solution. A single certificate can secure up to 250 domains/subdomains, significantly simplifying management, reducing costs, and strengthening your infrastructure’s security.
1. Secure up to 250 domains with one certificate
Comodo Multi‑Domain SSL includes 3 domains by default, but you can expand it to cover up to 250 SAN domains or subdomains. For example:
- main.com
- shop.main.com
- blog.main.com
- api.main.com
- and other domains like main.ua, corporate.com
Ideal for:
- global sites with multiple language versions
- multi-brand companies
- fast-growing startups
2. Installation on unlimited servers
One certificate can be installed on an unlimited number of servers, VPS nodes, or service instances. This is essential for:
- load balancers
- CDN or edge servers

3. Strong encryption: 256-bit TLS
- TLS 1.2/1.3 protocol with 256-bit AES encryption

4. Browser compatibility
Compatible with over 99.9% of browsers and mobile platforms (Chrome, Safari, Firefox, Edge, Android, iOS), ensuring reliability and user trust.
