Marketing and demand generation teams bleeding budget on junk leads will see immediate ROI from CHEQ Form Guard, which stops fake submissions before they hit your CRM or sales queue. The tool covers calendar appointment protection and retargeting campaign defense alongside form blocking, meaning your entire funnel gets filtered, not just landing pages. Skip this if your conversion rates are already clean or you're expecting a silver bullet for broader bot traffic on your website; Form Guard is specifically built to protect lead capture workflows, not general site traffic or API endpoints.
AppSec teams running CI/CD pipelines who need fast, actionable vulnerability scanning without vendor lock-in should evaluate Flan. Its free pricing and 4,141 GitHub stars signal strong adoption among developers who actually run the tool in production, not just evaluate it. Skip this if your team needs managed remediation workflows or integration with expensive commercial platforms; Flan is a scanner, not a platform, and requires you to build the response layer yourself.
