"SumSub Best for Verification"
5/5
What do you like best about Sumsub?

It's the easiest platform to use to prevent fraud in terms of documents. And helps verify if the identity of people is legit to prevent fraudsters and detect fraudulent activity before it happens. It also has the best customer service which is instant to what we need. Definitely good for day-to-day use. Review collected by and hosted on G2.com.

What do you dislike about Sumsub?

Sometimes the automation of verification flags users wrongly but when we clarify everything the issue is sorted. Review collected by and hosted on G2.com.

"Currently best solution on the market, but has its drawbacks"
4/5
What do you like best about Sumsub?

Simple UI/UX, simple verification flow, good protection against fraud and forgery, internal block list. Review collected by and hosted on G2.com.

What do you dislike about Sumsub?

Sometimes pending is taking a long time and sometimes wrong OCR from Italian IDs (paper ones). I couldn't find a feature to make a static link for a verification (so that any person could visit it and pass verification and it appears in the admin dashboard), like it is on other KYC services. Also when I create a new link for a new person it expires quickly and I have to send a new one. Also I couldn't customize selfie type - nothing is available except Advanced liveness check.

"So powerful"
4.5/5
What do you like best about Sumsub?

After comparing Sumsub and Veriff, I found that Sumsub has very powerful and customizable data analysis features. It allows for adding my company's logo and filling out questionnaires, which is very practical. However, the speed of analyzing and processing the legality of data needs improvement, and customer service response times could be better Review collected by and hosted on G2.com.
