CST VerdictBased on our analysis of available product data, here is our conclusion:
DevOps and platform security teams running containerized infrastructure will get immediate value from Falco Rules because syscall-level detection catches runtime anomalies that network and file-integrity tools routinely miss. The ruleset is free and officially maintained by the Falco project, meaning you're not betting on a vendor's roadmap or paying per-rule licensing. This is not the tool for organizations that need a managed, hosted threat hunting platform or one-click compliance reporting; Falco Rules requires operational integration into your runtime security stack and assumes your team will tune and extend rules for your specific environment.
Threat hunters and security researchers who need to rapidly search public Git repositories for leaked credentials, hardcoded secrets, or malicious code patterns will find Grep App's regex and case-sensitivity controls faster than GitHub's native search. The free pricing means zero friction for ad-hoc hunts across your team without procurement cycles. Skip this if you're looking for automated scanning of your own repositories; Grep App is built for hunting in the open-source wild, not internal SAST integration.
