5arz vs ad verification
Ad-verification tools score traffic and estimate whether it was a bot. 5arz signs proof that a live, verified person was behind the impression.
Detection tools like IAS, DoubleVerify and HUMAN score traffic. 5arz signs proof that a verified person was there.
Screen with detection. Stand behind the traffic that matters with a seal the buyer can check.
How each one works
Side by side
| Feature | 5arz | Ad verification |
|---|---|---|
| Method | Signed, affirmative proof | Probabilistic scoring and filtering |
| Output | A signed, portable credential | A risk score or rate |
| Anyone can check it downstream | Yes — against the public key, offline | No — you trust the vendor’s number |
| A person was present | Proved and signed | Estimated |
| Where the proof lives | Travels with the impression | A vendor dashboard |
A comparison of approaches, not of any one vendor. Capabilities differ by vendor and change over time.
Which one you need
- You need broad screening across a large buy
- Filtering obviously invalid traffic is enough
- You need signed proof a person was present
- Premium inventory or verified-human deals
- Agentic commerce, where a buyer must check it
Or use both. Screen with detection. Then stand behind the traffic that matters with a 5arz credential the buyer can verify.
Questions
Is 5arz an ad-verification alternative?
It’s the affirmative-proof layer alongside detection. Detection screens; 5arz signs proof a verified person was present, which anyone can check.
Can it run alongside my current vendor?
Yes. Screen with detection, then add 5arz credentials to the inventory you want to stand behind.
How does a buyer verify a credential?
It’s an ES256 JWT checked against the public JWKS with any JWT library — no 5arz SDK needed. Try the free verifier.
Why does signed proof matter for ads?
About 51% of web traffic is bots (Imperva Bad Bot Report, 2025). A signed credential can be checked downstream; a detection score can’t.
