The Certificate Authority the World Relies On
Sectigo (formerly Comodo CA) is the world's largest commercial Certificate Authority by volume, having issued over 100 million SSL/TLS certificates since 1998. When you see the padlock on a huge proportion of the world's websites, there's a good chance Sectigo issued it. Their certificates are trusted by every major browser, operating system, and device — from Chrome and Safari to Android and iOS.
Rebranded from Comodo CA in 2019, Sectigo brought the same rock-solid infrastructure and trust chain under a modern identity focused entirely on digital certificates and online security. They are an AICPA SOC 2 certified organisation and comply with all CA/Browser Forum baseline requirements.
