When you've done the hard work of renewing the certificate, don't forget this last piece of the renewal process! Microsoft provides certificate auto-enrollment that can be configured with GPO. This allows devices to automatically enroll for a new certificate when the current one is about to expire. In order for this to work, you need to configure an auto-enrollment policy and certificate templates. Remember to use security groups if you are granting template permissions. Once the templates have been configured, add them to your Enterprise CA so auto-enrollment can begin.
With SecureW2, certificate templates can be configured so certificates stay valid for any number of years. A practical example could be for a university where you could easily set up group policies so when users enroll for a certificate, your system automatically issues 4 year certificates to students and 8 year certificates to faculty and staff.
Sending out automated certificate expiration notifications is critical to maintaining a secure network. You may recall the Experian Data Breach that occurred in where one of the main factors for the beach was a certificate that expired without anyone noticing. We recommend all our customers take advantage of our automated certificate expiration notification emails. When you generate a CA with SecureW2, you can select when and how often end users will be notified when their certificates are about to be expired.
The screen above shows the interval options shown in days that are available. SecureW2 will automatically email end users when a certificate expires and will instruct them on how to re-enroll. SecureW2 takes advantage of SCEP Simple Certificate Enrollment Protocol that can simplify the enrollment process so you can enroll any device for a certificate without any user interactions necessary.
With SCEP you can easily configure enrollment policies that can auto-renew certificates for managed devices as soon as they expire. This takes away any chance of forgetting an expired certificate, and with our GUI, you can monitor all your active certificates to ensure nothing falls between the gaps. Configuring your certificate management system is of the utmost importance for properly securing your network.
SecureW2 offers an affordable and easy solution for managing your entire PKI, allowing organizations to rely on an efficiently automated system and minimizing human error wherever possible. Check out our pricing page to see how SecureW2 can help you and your organization.
