AWS announced on August 19 that Web Search on Amazon Bedrock AgentCore, the managed tool that lets AI agents ground their answers in live web results, now supports domain filtering and published-date filtering on a per-request basis. Agents can include or exclude up to 100 domains per list and constrain results to a specific date range, without an administrator reconfiguring the service centrally. The tool also expanded beyond its original US East region to Europe (Ireland) and Asia Pacific (Tokyo).
Why it matters to enterprise AI buyers
The feature itself is incremental, but the reason AWS built it is not: enterprise customers running agents in regulated industries had been asking for exactly this kind of per-request source control, because an agent that can pull from any domain on the open web is a governance problem for a bank, healthcare system, or insurer before it is a capability advantage. AWS pitching domain and date filtering as compliance tooling, not just search quality tooling, confirms that agent governance has become a purchasing criterion cloud vendors are now competing on directly, alongside model quality and price. For a CIO or CAIO evaluating agent infrastructure vendors, source-control granularity belongs on the same evaluation checklist as model benchmarks: an agent that can be scoped to trusted domains and recent content is meaningfully easier to defend to an internal risk committee than one that cannot.
