Rails applications frequently get compromised hours after vulnerabilities are disclosed, before many teams can patch. Current monitoring is either too broad or requires manual setup.
Create a specialized service that watches Rails security announcements and immediately notifies subscribed teams. Include automated checks for vulnerable dependencies and deployed patches.
Sell to engineering managers as part of their security stack. Charge per application monitored with volume discounts.
Start with simple email/SMS alerts when CVEs are published. Later add CI/CD integration and compliance reporting.
The risk is existing security tools adding this feature, so focus on Rails-specific expertise and rapid response.
