DSPs Tell Clients Fraud Runs 1 to 3 Percent. Anura's Scans Keep Finding Half.
DSPs tell clients their fraud rate runs 1 to 3 percent, already filtered out before the buy. Anura's post-click scans of DSP traffic keep finding roughly 50 percent bots, malware or human fraud, with individual scans running from about 40 percent to more than 90.

- The 1 to 3 percent figure is the DSPs' own self-reported GIVT catch rate, not a verified measurement.
- Pre-bid filters get about 20 milliseconds per decision; Anura checks more than 800 data points at the landing page.
- The highest scan, over 90 percent, came from a major university's agency buying through one of the largest DSPs.
- The MRC says it often sees filtration rates in audits well above 1 percent, varying by metric, property, locale and filter type.
- Kahn's July brief put growth in the fraud Anura catches at more than 50 percent over six months, driven by AI.
On the record
“The gap isn't a discrepancy, it's the difference between what a 20-millisecond IP check (GIVT filter) can see and what 800 data points (SIVT filter) at the landing page can see.”
“It used to take a genuinely skilled developer to build effective fraud infrastructure. Now, if you can write a prompt, you can build a bot.”
