Sectigo is a leading Certificate Authority and provider of certificate lifecycle management (CLM) solutions that help enterprises secure websites, software, email, and connected devices. Its CA-agnostic Sectigo Certificate Manager (SCM) automates issuance, discovery, renewal, and governance for public and private certificates across hybrid and multi-cloud environments—supporting standards like ACME/SCEP/EST and 50+ integrations. Organizations rely on Sectigo for SSL/TLS, private CA, S/MIME email, code signing, and document signing to establish digital trust at scale. Formerly Comodo CA, the company rebranded as Sectigo and, in 2025, acquired Entrust’s public certificate business—expanding its enterprise footprint. Together with partners, Sectigo helps customers reduce risk, prevent certificate-related outages, and centralize PKI management.
