Why Monitor SSL Certificates?
Prevent Service Disruptions
Expired SSL certificates cause browser warnings and block access to your websites, resulting in lost traffic and revenue. According to a GlobalSign study, 65% of organizations have experienced outages due to expired certificates.
Maintain Customer Trust
Security warnings damage your brand reputation and erode customer confidence. Research by SSL.com shows that 84% of users would abandon a purchase if they saw a security warning.
Ensure Compliance
Many regulatory frameworks like PCI DSS, HIPAA, and GDPR require proper certificate management. Automated monitoring helps maintain compliance and avoid penalties.
Reduce Administrative Overhead
Manual certificate tracking is time-consuming and error-prone. Automated monitoring saves IT staff time and reduces the risk of human error.
