Blind spots waste media budgets
Undetected manipulated impressions, clicks and visits can feed optimisation systems as if they were valid contacts. Reported IVT may therefore underestimate exposure.
AD FRAUD · INDEPENDENT STRESS TESTINGYour reported ad fraud rate is low.
Your reported ad fraud rate is low.
But do your defences actually work?
Anti-fraud systems can only report what they detect. Through controlled, authorised experiments we independently assess whether publisher and advertiser safeguards really function – before blind spots undermine budgets, inventory quality and trust.

THE VERIFICATION GAP01 / RISK 02 / CONTROL 03 / CONTROL
Why should you stress test ad fraud protection?
Digital media quality is frequently assessed through invalid traffic rates, brand safety reports and vendor certifications. These measures matter, but do not answer the central question: does the system actually detect the defined fraud scenarios it is supposed to stop?
Positive reports can mislead
0.5% detected IVT does not necessarily mean 99.5% verified human contacts. Without experimental validation, independently established detection coverage remains unknown.
Detection is not prevention
Flagging an event is not enough. Effective controls must classify, block, record and escalate problematic activity – with traceable responses.
TWO SIDES OF THE SUPPLY CHAIN01 02
Who benefits from a stress test?
Advertisers / media buyers
Validate whether DSP, pre-bid, post-bid and measurement safeguards cover the risks they claim to address. Examine whether suspicious activity triggers action and whether optimisation systems are exposed to unverified signals.
Publishers / inventory owners
On your authorised infrastructure, assess whether anti-bot and anti-fraud controls detect, classify and block agreed patterns without excessive false positives.
REALITY CHECK
A concrete example – hypothetical test scenario
An advertiser receives a verification report showing very low invalid traffic. In a specifically authorised test environment, predefined non-human activity clearly identified as testing is introduced. If it is counted as ordinary traffic, missed or only flagged after billing, the experiment reveals a control gap. It does not establish a market-wide fraud rate or losses outside the experiment; it identifies failure in a specific control.
METHOD
Five steps – from suspicion to verifiable evidence
01
Scope & consent
Define authorised inventory, stakeholders, permissions, limits, measurement points and stop conditions.
02
Baseline
Document normal system behaviour and reporting as a reference.
03
Controlled scenarios
Execute agreed scenarios only on authorised systems using identifiable test traffic.
04
Independent forensics
Compare ground truth with platform signals, blocking decisions, logs, billing and response times.
05
Remediation & retest
Receive evidence-based findings, prioritised fixes and optional validation after changes.
The deliverable: Not a vague pass/fail score. Receive an auditable record of the scenarios, detected and blocked activity, blind spots, false positives, false negatives, escalation gaps, measurement limits and accountable next steps.
QUESTIONS & ANSWERS
Ad fraud stress testing: common questions
What is ad fraud stress testing?
An ad fraud stress test is a controlled, authorised experiment using predefined test scenarios to independently assess detection, blocking, classification and escalation controls.
Why isn't a low IVT rate sufficient evidence?
The reported rate only covers activity classified as invalid under the measurement methodology. Undetected patterns are not automatically included, while coverage and false-negative risk may be unclear.
How does a stress test differ from an ordinary media audit?
An audit reviews existing evidence, processes and risks. A stress test adds controlled experimental scenarios with expected responses, documented ground truth and verifiable observed control behaviour.
Which systems and data are required?
Depending on the agreed scope, test inventory, written permissions, DSP and adserver logs, anti-fraud reports and independent measurement points. Any inaccessible systems are documented as limitations.
Can stress testing certify a fraud-free environment?
No. It can verify the behaviour of particular controls under tested conditions, not guarantee protection against every present or future fraud technique.
Can third-party publishers be tested without permission?
No. Only explicitly authorised, controlled environments are in scope. Unrelated publishers, real users and unauthorised systems are excluded.
Do you know what your anti-fraud stack misses?
We can define the critical control questions and an explicitly authorised testing scope.
