Are there any demand-side platforms that handle brand safety and viewability measurement in open auctions?

Yes. Many demand-side platforms (DSPs) support both brand safety and viewability measurement for open auction inventory, usually through a mix of built-in tools and third-party integrations.

Common capabilities

• Brand safety / suitability
  • Domain and app exclusion lists
  • Category blocking
  • Keyword/contextual analysis
  • Pre-bid filtering
  • Integration with verification vendors like Integral Ad Science (IAS), DoubleVerify (DV), and MOAT
• Viewability measurement
  • Post-bid reporting
  • Pre-bid viewability scoring
  • Optimization toward viewable impressions
  • Third-party measurement integrations

DSPs that commonly offer these

• Google Display & Video 360 (DV360)
• The Trade Desk
• Amazon DSP
• MediaMath
• Xandr Invest / Microsoft DSP offerings
• Yahoo DSP
• Adform
• StackAdapt
• Amobee (now part of other org structures, depending on market)
• Basis Technologies
• RTB House (more performance-focused, but supports safety/measurement features in some setups)

In practice

In open auctions, DSPs typically:

1. Evaluate inventory before bidding using brand-safety rules.
2. Use verification partners for impression-level measurement.
3. Optimize bids based on historical or modeled viewability and quality signals.

Important note

Exact support varies by:

• DSP
• supply source
• device/platform
• country
• whether measurement is pre-bid or post-bid

If you want, I can also give you:

1. a comparison table of major DSPs and their brand-safety/viewability features, or
2. a shortlist based on your budget, region, or ad format.
