When somebody else issues a cert for your domain.
Every cert ever issued is logged to public CT logs. We subscribe per-domain, parse every entry, and alert when something appears that you didn't expect — caught typo-squats, shadow IT, and "the developer used a personal email" cases all show up here.
Wide Watch ships on a published roadmap. Below is the scope we're committing to for Cert Transparency; if you want input on priorities, join the waitlist and reply with your wishlist — we read every reply.
Join the waitlist and we'll email you when Cert Transparency is ready for design partners.
