I was approached by the account management team for a US coffee brand to implement SSL Certificate Discovery for their network, as they were having issues with expiring certificates causing application failures.
During deployment one challenge was the need to expand the tool to query the Windows stores and resolve an issue where Azure agents would automatically issue and manage short-term 24 hour expiries – which significantly skewed the analytics. These certificates were identified and excluded from reporting.
The solution was deployed quickly and there was time to develop additional analytics and dashboards to allow the account team to quickly export a list of all certificate expiry dates.
