A certificate that expires on Tuesday should not wait until Friday. Prove a domain is yours and we check it free, once a week, emailing you anything that changed. Pro checks it once a day, looks at every host on the domain, and keeps 365 days of history — so you hear about a problem in hours rather than days.
