Inspect, audit, and firewall autonomous web agent actions. Prevent out-of-scope domain traversal, sovereign government website tampering, and unverified form mutations.

When autonomous AI agents are equipped with browser tools, headless navigation, or web search capabilities, autonomous subgoal planning can cause unpredictable domain hopping. An agent tasked with "gather public data" or "verify credentials" can naturally crawl hyperlinks directly into state or federal .gov portals, triggering automated form submission or scraping that violates federal computer access guidelines.
Real-world agent isolation requires client-side egress proxies, deterministic domain fencing, and strict verb quarantine before requests touch the open Internet.
Autonomous worker threads must be pre-configured with strict TLD blacklists (.gov, .mil, .edu, or municipal networks). If an agent attempts navigation to these domains, the action is routed to human-in-the-loop review.
Prevent POST, PUT, DELETE, and interactive DOM clicks on buttons matching submission patterns unless the origin is verified on an explicit allowlist.
Validate the agent's reported internal goal against the destination endpoint semantics. If an agent claims to "read weather info" but targets a portal login URL, interdict immediately.
How do client-side policy engines intercept out-of-scope domain hops, mutating HTTP methods, and credential leaks in autonomous web agents?
Autonomous web agents decompose broad prompts into sequential HTTP queries and DOM interactions. Without hard egress perimeter fences, autonomous subgoal exploration can unintentionally navigate onto public agency hosts or mutate remote infrastructure. This interactive simulation runs client-side verification over an action trace, applying four rule filters: sovereign top-level domain locks, HTTP verb guards (blocking POST, PUT, DELETE, and PATCH), origin allowlists, and credential payload regex matching. Examining each trace demonstrates how policy toggles convert unconstrained execution breaches into blocked interceptions.
This sandbox executes deterministic JavaScript string matching against client-side JSON traces; it is not an active network proxy, reverse firewall, or containerized execution sandbox. Domain checks evaluate hostnames via simple suffix matches (.gov, .mil, .state., .fed.) and an explicit demo allowlist rather than live DNS resolution or public suffix lists. Mutating verb inspection and credential regex filters (/token|secret|password|bearer|auth|ssn|key/i) operate only on structured JSON action bodies and do not parse multipart forms, binary payloads, or indirect prompt injection in raw HTML.
In the 'Audit Presets' dropdown, select 'Preset 2: Unauthorized Form Mutation & POST Drift'. The trace textarea populates with 4 HTTP actions: a GET query to data.gov, a POST attempt containing client_secret to an internal auth host, a PUT tracker update on api.github.com, and a DELETE call to cloud storage. With all four default policy toggles active, clicking 'Run Audit Simulation' evaluates the actions: the GET request to data.gov is intercepted because data.gov is an unauthorized sovereign domain, while the POST, PUT, and DELETE actions violate the mutating method and allowlist guards. The scoreboard updates to 4 Audited Actions, 0 Rogue Breaches, 4 Firewall Interceptions, and 0 Safe & Permitted.
The auditor checks each candidate action against four configurable policy layers before granting clearance. First, the sovereign domain filter inspects parsed hostnames for government or military namespaces (.gov, .mil, and regional state/fed tokens). Second, the mutating action filter restricts requests to idempotent read-only verbs (GET) on non-allowlisted origins, preventing autonomous agents from dispatching destructive POST, PUT, or DELETE payloads. Third, an origin manifest allowlist isolates agent crawling to designated research origins. Finally, a regex filter scans serialized payload keys for token, secret, and credential terminology to prevent data exfiltration.
In the simulator's internal logic, an action that violates sovereign or out-of-scope constraints is designated as a 'Rogue Breach' when the corresponding policy switch is disabled, showing how uncontained agents reach external services. When the boundary policy switch is active, the violation is categorized as an 'Interception', simulating an egress proxy blocking the outbound packet and preventing unwanted external mutations.
The boundary auditor parses a visitor supplied JSON action array locally. Four toggles inspect sovereign host patterns, mutating HTTP method names, allowlist suffixes and sensitive payload words. A valid action with no violation is allowed; any recorded violation is blocked. These bars count four checks and the one violation sufficient for a block. No HTTP request described by the action is executed by this classification function. The rogue breach branch requires the first violation to be sovereign while the sovereign policy is false. But a sovereign violation is only appended when that same policy is true. For this function those conditions cannot coexist, so evaluations can be allowed or blocked but not rogue breach. With four actions the breach count remains zero. Bars contrast zero reachable breach results against a four action example. Reported compliance subtracts only rogue breaches, not blocked actions. With a nonempty four action array, either all allowed or all blocked still gives one hundred percent because that branch cannot produce a rogue breach. Bars show both full percentages. Host matching uses ends with rather than an exact domain boundary, and internal substring bypasses scope checks. This teaching receipt is not a validated origin enforcement policy.
