What teams using Provero say
"We tested Provero as an additional layer for our KYC data provenance due diligence and the outcome reports were very insightful. We could identify data that was part of a legacy breach, data that existed on national suppression files along with detailed phone and email validation flags. Really impressive solution and would recommend to anyone onboarding new data or to check existing datasets. It enabled us at Dataxcel to make informed decisions especially around compliance."

Start with a single check
Every check runs on its own, as a real-time API call or a bulk upload. Take the one you need today, or combine several in one request. Prices step down as your volume grows.
◆ Free credits to run a real sample of your own data through every checkOne record. More answers.
Run every check in a single request, real-time or in bulk, and get it all back in one response: whether the data works, whether the identity details match, what risk is attached and whether you're allowed to make contact.
Frequently Asked Questions
What Provero checks, how fast it runs and what it costs.
Does Provero do more than just email and phone validation?
Yes. Provero answers four questions about the same record, is the data real, are they who they say they are, is this risky, and am I allowed to contact them. Phone, email, name, UK and global addresses, mobile-network identity and age checks, SIM swap, IP fraud, breach exposure and TPS screening, all through one API.
How is Provero different from a single-purpose verification API?
A point solution tells you whether one field passed one check. Provero can run that same single check, and it can also tell you whether the identity details match independent data, whether there is fraud or breach exposure attached, and whether you are allowed to make contact, in one request. You know far more about the record before you decide what happens to it.
How does Provero help decide whether a record is usable?
Different uses demand different confidence in a record. One that is good enough to send a marketing email may not be good enough to approve an identity-sensitive action or open an account. Provero tells you more about the record, whether the data works, whether the identity details match independent mobile-network data and what risk is attached, so you can set the bar your use case needs and act on it.
How does Provero fit into a KYC or IDV workflow?
Most often as the step before it. KYC checks cost pounds per record. Provero costs pennies, so running a record through verification and risk checks first means you are not paying to run identity checks on data that was never going to pass. Dead numbers, undeliverable emails and records with breach exposure get caught before they reach the expensive part of the waterfall.
If you need the identity check itself, Mobile Network Identity Verification is a Provero check in its own right. It corroborates supplied name, address, date of birth and age against mobile network data, and runs in the same request as everything else.
What does breach exposure tell me?
Whether an email address, phone number or IP appears in known breach data, how many separate breaches, and how old the first one is. That last figure does most of the work.
On a single record it means very little, because around half of real consumer data carries breach exposure. It works across a whole source. Clean sources run at roughly 50% exposure with a first breach three to five years old. Recycled stolen data runs at 70% to 100%, with a first breach nine to eleven years old, and the same records turning up in six or more breaches each. A supplier can lower a breach rate. Nobody can make old data young.
We call that read the Breach Age Index.
Can Provero analyse bulk data?
Yes. Every check runs as a real-time API call or as a bulk upload. A single bulk workload of 1.4 million records has been processed with two checks running against every record, 2.8 million lookups in one file. Bulk speed depends on how far the workers scale, so a 100,000-record file takes about twelve minutes on a cold run and completes in under three once autoscaled.
How fast is it?
HLR responds in approximately 467ms at the 95th percentile, measured at 50 requests per second under sustained load rather than idle, and a 100,000-record HLR bulk file completes in under three minutes once the workers have scaled to it.
Can Provero handle production volume?
Yes. 1.4 million records have been processed in a single bulk upload, with two checks running against every record, 2.8 million lookups in one file. The platform carries ongoing API traffic and bulk processing from active users every day. It is also simple enough to check a single record.
Is my data secure?
Yes. Provero is designed with enterprise-grade privacy and security at its core. Our platform is built entirely with ISO 27001 compliance standards in mind, employing end-to-end encryption (TLS in transit and AES-256 at rest), strict access controls, and fully GDPR-compliant data processing workflows.
