"Multi-Layer Security for Peace of Mind"

4/5

What do you like best about Sumsub?

There are several layers of security in place to ensure a thorough, well-refined security check. Review collected by and hosted on G2.com.

What do you dislike about Sumsub?

It’s not very clear when it comes to manually approving user requests. Seeing only “Action Needed” is confusing; you end up having to double-check everything and cross your fingers, hoping you’ve done it right. Review collected by and hosted on G2.com.

"A Comprehensive Tool, But Is It Genuinely Secure?"

3.5/5

What do you like best about Sumsub?

Sumsub offers a wide range of verification features and seems to cover many different document types and regions. The platform is somewhat powerful and has a comprehensive set of tools for helping with compliance. Review collected by and hosted on G2.com.

What do you dislike about Sumsub?

Where to start: My primary concerns are about complexity and security.

Security Concerns: The verification process feels like it could be significantly stricter. At times, it seems too easy to bypass, which raises concerns about its reliability for catching sophisticated fraud.

Lack of Transparency: It's confusing to understand which specific security regulations (KYC, AML, etc.) are being applied and how. The platform needs to provide more transparency on the compliance logic.

Complexity: The platform could be more simplified. The user interface is not always intuitive and can be difficult to navigate, making the overall workflow feel more complex than necessary. Review collected by and hosted on G2.com.

What problems is Sumsub solving and how is that benefiting you?

The benefits are direct and essential to our entire business model. Sumsub is the "heart" of the operation, allowing the us (Voys Telecom) to function and grow.

Enabling the Core Value Proposition: Voys SA's promise to customers is a "quick online sign up" where they can get a system in 15 minutes. This speed is only possible because Sumsub provides instant, automated verification. Without it, the sign-up process would be slow and manual, completely breaking the core business promise.

Maintaining Regulatory Compliance: As a telecom company, Voys SA must adhere to strict regulations. Sumsub provides the necessary compliance layer, ensuring every new customer is verified, which protects the company from legal and financial penalties.

Scalability: Because the verification process is automated, Voys SA can onboard hundreds or thousands of new B2B customers without needing to proportionally increase the size of its compliance team. Sumsub handles the heavy lifting, allowing the company to scale.

In short, Sumsub solves the compliance problem in a way that enables and accelerates the company's automated, high-speed B2B onboarding, rather than being a bottleneck. Review collected by and hosted on G2.com.

Response from Irina Nam of Sumsub

edit

Thank you for such a thoughtful review and for trusting Sumsub as the “heart” of your onboarding at Voys SA. We’re really glad our coverage and automation help you deliver fast, compliant sign-ups.

We also truly appreciate your candid feedback on security strictness, transparency of compliance logic, and platform complexity. These are key focus areas for our teams, and your input will directly influence our ongoing improvements.

If you’re open to it, we’d be happy to review your current setup together to strengthen fraud controls and streamline the workflow for your team.

"Wide Product Support and Fast, Helpful SamSung Customer Support"

4.5/5

What do you like best about Sumsub?

I like the variety of products that SamSung supports and provides, which help us to answer basic compliance and legal requirements and needs. What I also like is the customer support on SamSung. Anytime we do have a problem, we receive information and additional support and feedback within minutes or hours. Review collected by and hosted on G2.com.

What do you dislike about Sumsub?

I think that end-customer-facing features can still be better, also in terms of user experience and customization. Second, part is webhooks information that do arrive within the customer verification process. We are unable to extract sufficient details from the user flow for analytics.
