hCaptcha vs. Arcjet

hCaptcha Enterprise is a comprehensive bot management and fraud prevention suite for organizations seeking to effectively identify and counter AI agent, bot, or human threats targeting their online properties. By seamlessly integrating hCaptcha into their websites, mobile applications, and APIs, organizations can proactively detect and mitigate automated bots and human fraudsters, minimizing security risks, preventing spam, and ensuring a superior user experience.

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.
