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. Development teams shipping APIs and microservices need ContrastProtect's runtime blocking because attacks get stopped at execution, not logged days later in a SIEM. The product embeds instrumentation directly in application code and delivers line-of-code visibility on active exploits, which means your incident response team actually knows what to fix instead of debating findings in a backlog. Skip this if your priority is vulnerability scanning before production; ContrastProtect assumes you need protection running live against zero-days and known exploits that your WAF already missed.
