Trust is broking, isn't it? Therefore, it is better not to miss the date of renewal of certificates.
If you do not remember when it ends, you can use our online check. Or, set up notifications for yourself once on all sites and do not worry anymore about this
The issued certificate must be certified by a trusted organization. We pay attention to this in real-time checks. If the intermediate certificate is not valid, the entire site is suspected of being phishing
In monitoring, we only check the expiration date of the certificate. And we start sending notifications 6 days before the delay, every day.
The term of the certificate may vary. If you generate it yourself - you only need to confirm ownership of the domain or site - then your certificate will be valid for 3 months. It's free.
If you buy a certificate from certified centers, then the validity period there can be from a year.
But in any case, the certificate must be renewed. Therefore, we advise you to monitor this event.
