CST VerdictShort answer
Developers building APIs and web services need bot and rate-limit protection that doesn't require security expertise to deploy, and Arcjet's SDK-first approach means you configure rules in code rather than wrestling with WAF consoles. The WebAssembly-based local execution runs decisions at the edge without sending traffic to external services, cutting latency and keeping you compliant with data residency constraints. Skip this if your primary concern is legacy OWASP Top 10 coverage on existing monolithic applications; Arcjet is built for modern application stacks, not retrofitting old infrastructure. Mobile security teams shipping Android apps to consumers will get real value from DexGuard's polymorphic builds and runtime self-protection, which force attackers to reverse-engineer a unique binary each time rather than reusing exploits across your user base. The tamper detection, debugger blocking, and emulator checks address the NIST Platform Security control directly by making the app itself resistant to tampering. Skip this if you're building internal enterprise apps for employees; the overhead and complexity aren't worth it when you control the device environment.
