Avoiding Outages: A Bank's Journey to Certificate Success with ServiceNow

This multinational banking and financial services company maintains hundreds of external TLS certificates and thousands more internally, which requires lifecycle activities critical for both service uptime and security.

Client size: 50,000+ Client industry: Financial Client location: Global


Key Challenges

On average, it took 2-3 days to renew a web-based certificate. While significant efforts were undertaken to improve this with a custom application, there have been multiple cases of certificates expiring within their environment, causing outage to systems and services. In addition, there have been cases of failed or missed certificate installations causing outages. ​
