CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mobile security teams and individual developers who need visibility into what their apps are actually doing on the network should start with PCAPdroid; it surfaces DNS leaks, tracker connections, and suspicious outbound traffic that platform-level logs routinely hide. The 3,800+ GitHub stars and zero-cost model mean you're working with battle-tested code that security researchers actively maintain. Skip this if you need centralized enterprise monitoring across hundreds of devices or real-time blocking policies; PCAPdroid is single-device focused and built for forensics and personal privacy, not fleet management.
