FAQs
Having a certificate inventory is important because it helps you understand your exposure to certificate risks. These include outages caused by certificate expiration, and security risks associated with certificates issued by untrusted CAs. Visibility into certificate expiration also helps prevent unplanned outages and makes compliance easier.
Certhawk monitors certificate transparency logs in real time to provide visibility into certificate issuance and expiration. It also provides alerts for certificates issued by untrusted CAs, and can help discover certificates issued to similar looking domains which may be used to impersonate your domain for phishing attacks.
