What is ias-ie?

If you run ads, confirm ias-ie's purpose before blocking it. Some intelligence gatherers measure ad placements or evaluate pages for brand safety, and blocking those agents can interfere with advertising systems. If this one serves a different purpose, weigh any research visibility against sharing business or page-level data with third parties. Almost none of the top websites we track currently have robots.txt rules for ias-ie.

Yes. ias-ie is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether ias-ie respects it.

No special access. ias-ie can read publicly available pages but cannot bypass authentication. Assume anything you publish openly may be collected.

A client of Integral Ad Science may be gathering competitive intelligence, measuring advertisements, or evaluating content for brand safety. The pages requested reflect that client's objective.

Agent Analytics tracks ias-ie visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "ias-ie". Look for repeated requests to the same small group of commercial or ad-supported pages. Because ias-ie does not publish a verification method, any client can claim its identity and a log match is only a clue.
