CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:

PreEmptive Dotfuscator

Teams shipping C# and .NET applications will find PreEmptive Dotfuscator essential for blocking reverse engineering at runtime; it's one of the few tools that combines rename obfuscation with active tamper detection and self-protection behaviors rather than passive code hardening alone. The multi-platform support across .NET, MAUI, Xamarin, and Android means a single vendor can protect your entire mobile and desktop portfolio without tool sprawl. Skip this if your primary concern is detecting attacks already in progress; Dotfuscator is prevention-focused and lacks the runtime monitoring depth needed for behavioral threat detection post-compromise.
