Programmatic Ad Fraud Defense

MediaGuard detects and prevents digital advertising fraud. MediaGuard and FraudSensor work together to detect invalid traffic (also known as IVT) and ensure that your ads are seen by real humans—not bots in disguise.

If you’re a HUMAN user, our Snowflake integration lets you access the full scope of data collected by our tools, including the pre-bid IVT predictions made by MediaGuard and the post-bid IVT detection and analysis performed by FraudSensor. These datasets offer event-level data about individual bid requests and impressions, including HUMAN’s “bot or not” decisions, detailed threat breakdowns, and information about the traffic sources driving each event.

Sample Tables:
- pre-bid IVT prediction data (MediaGuard): mediaguard_prebid
- sampled pre-bid IVT prediction data (MediaGuard): mediaguard_prebid_sampled
- post-bid IVT detection and analysis (FraudSensor): mediaguard_postbid

Fields Included in MediaGuard pre-bid data:
- supplier_id: The supplier id for the requests
- publisher_id: The publisher id for the requests
- device_type: The device type for the requests
- media_type: The media type for the requests
- ivt_bot_category: The various IVT categories detected
- requests: Approximate number of requests
and 16 more fields.

Fields Included in MediaGuard sampled pre-bid data:
- supplier_id: The supplier id for the requests

- domain: The domain for the requests
- app_id: The app id for the requests
- ivt_bot_category: The various IVT categories detected
- requests: Approximate number of requests
and 16 more fields.

Fields Included in MediaGuard post-bid:
- ct: Query parameters used to fetch HUMAN's payload excluding c1 to c10
- custom: c1 to c10 query parameters used to fetch HUMAN's payload
- app_mismatch: Whether the app id claimed by the user and detected by HUMAN matched or not (mobile only)
- detected_app_id: The app id detected by HUMAN (mobile only)
- environment: The user's environment used for the connection
- ivt_bot_category_str: The IVT categories detected
- domains: Various domains related to the ad viewed by the user
- bot: Whether ad was viewed by a bot or not
- givt: Whether the bot was GIVT or not
- sivt: Whether the bot was SIVT or not
and 21 more fields

MediaGuard可检测并防范数字广告欺诈行为。MediaGuard与FraudSensor协同工作，可检测无效流量（invalid traffic, IVT），确保广告仅被真实人类用户浏览，而非伪装的机器人。
