certSIGN SSL Certificates review
certSIGN covers DV, OV, and OV wildcard certificates for HTTPS website authentication.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
certSIGN SSL Certificates is a paid, cloud-deployed service for website authentication and HTTPS encryption. Its catalog targets personal websites and blogs through Domain Validation (DV), while business and brand websites can use Organization Validation (OV). An OV Wildcard option extends coverage across multiple domains and subdomains, making the range relevant to solo owners, small businesses, mid-market teams, and enterprises that need these validation types.
The published catalog contains three plans: DV SSL Certificate, OV SSL Certificate, and OV Wildcard SSL Certificate. DV validates domain ownership or control. OV adds organization and requester verification, and the wildcard plan includes the same organization validation plus coverage for multiple domains and subdomains up to 250 characters in total. Product pages describe annual certificates, while a policy updated in January 2026 states that maximum certificate duration becomes 200 days from March 15, 2026. Buyers should align procurement and renewal planning with the policy that applies to their issuance date.
certSIGN’s fit is strongest when standard DV or OV validation, including wildcard coverage, is the requirement. The service lists email and phone support and identifies ISO27001 compliance, giving organizations defined support channels and a stated security-management credential. Its scope is narrower for teams seeking EV validation, automated certificate operations, or broader platform integration workflows. Choose certSIGN when its DV, OV, and wildcard options match your domain structure and verification needs; consider another provider when those additional capabilities are central to deployment.
