Cool Query of the Week June 12, 2025: Certificates with a specific name that expire in the next month

Hello again! In this week’s Cool Query of the Week, I’m highlighting a way to search for certificates containing a specific name that expire in the next month. Swap out the example domain for your domain of interest and set up a collection to get alerts when new certificates are added to this query’s results.cert.parsed.subject.common_name: "example.com" and cert.parsed.validity_period.not_after >= "now" and cert.parsed.validity_period.not_after < "now+1M"
