Arcjet

Arcjet adds runtime checks to supported coding agents and custom AI applications. Its documentation describes hooks for checking tool calls, policies that limit outbound domains, and input screening for suspected prompt injection or sensitive data. Teams can review events in the console and choose which policies to enforce.

For a coding team, a useful first test is to run one rule in dry-run mode on a disposable project. Compare a harmless read of a public configuration file with an attempt to read a synthetic credential file. Inspect the audit record and verify that the rule would treat the two actions differently. Then check that your other controls still enforce which files and services the agent can reach.

Arcjet’s pricing page lists paid plans with usage fees and a 15-day trial. It distinguishes agent requests from ordinary web requests, so estimate the relevant request volume when comparing costs.
