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 shipping apps that face active reverse engineering or tampering attacks need Wultra In-App Protection for its runtime shielding that works without relying on cloud-side detection. The platform covers both NIST PR.PS (platform hardening through app-level controls) and ID.RA (risk assessment of mobile-specific threats), which matters because most mobile security gaps live in the app binary itself, not the network. Skip this if your threat model is web-only or if you need post-breach forensics; Wultra prioritizes prevention over incident response.
