Organizations need better ways to monitor certificate authorities for potential compromises. Build a tool that tracks CA activity and alerts on suspicious behavior.
Target organizations that rely heavily on SSL/TLS certificates, like e-commerce sites and financial institutions. Offer a paid SaaS with tiered pricing based on monitoring volume.
Start by monitoring major CAs and common compromise indicators. Later add support for more CAs and advanced monitoring features.
The risk is convincing organizations to prioritize CA monitoring.
