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 teams at mid-market and enterprise organizations should pick Promon Shield for Mobile™ if reverse engineering and tampering are your actual threat model, not theoretical ones. Post-compile integration means you inject protection without touching source code or rebuilding your CI/CD pipeline, which matters when you're shipping iOS and Android apps on existing schedules. The tool covers rooted and jailbroken devices with on-device AI models, addressing threats most mobile solutions ignore until your app is already compromised. Skip this if your mobile security concern is primarily data leakage from misconfigured APIs; Promon is built for runtime threats, not backend hardening.
