AppTrana vs. Arcjet

Trusted by over 6,500 customers across 95+ countries, it offers unmetered protection with 100% availability.

Arcjet is runtime security for AI agents. It puts the decision where the action is: block prompt injection, stop PII leaks, block bots, and add guardrails to tools, APIs, and database calls. Identity tells you who is asking, but it cannot tell you what happens next. Arcjet runs inside the code that takes the action, so every agent action is observed in the run it belongs to, checked before it executes, and kept as evidence afterwards. Each check returns a decision your code acts on: allow, block, redact, or hold for review.
