Online gambling operators operate under intense regulatory pressure. Authorities expect strong identity and age controls to prevent underage gambling, money laundering and fraud as well as protect players. At the same time, players expect a near-instant “time to play” experience.
That tension creates a real commercial risk:
This is why most iGaming compliance teams invest in dedicated KYC software for online gambling rather than relying on manual checks or disconnected tools. The goal is not just compliance, but balance: meeting regulatory obligations while protecting player conversion.
In this guide, we’ll compare some commonly used KYC software solutions for online gambling compliance: GBG, Signzy, Sumsub, and iDenfy.
When you compare KYC vendors for iGaming ID verification, focus on four outcomes:
| Core need | GBG | Signzy | Sumsub | iDenfy |
| Coverage | Identity verification, data, documents, and biometrics across 195+ countries with deep gaming market experience and regulatory expertise | Verification across 180+ countries and 10,000+ document types with strong device and data validation | Global coverage with strong localization and multi-language support, suitable for regulated and emerging markets | Coverage across 200+ countries and territories and 3,500+ government-issued documents |
| Risk-based workflows | Highly configurable, automated journeys that fast-track trusted players and apply enhanced checks only when risk thresholds are triggered | No-code rules engine allowing multi-level risk decisions without heavy engineering | Code-free orchestration of checks placed at any stage of the player journey (onboarding to withdrawal) | Customizable verification flows with rule-based step-ups for higher-risk users |
| AML and ongoing monitoring | Automated sanctions, PEP, and adverse media screening with continuous monitoring aligned to regional AML requirements | AML screening and transaction monitoring using AI-driven behavioral analysis | AML screening at onboarding and continuous monitoring with unified risk scoring | AML screening against sanctions, PEPs, and adverse media with ongoing monitoring alerts |
| Fraud and bonus abuse prevention | GBG Trust Network provides cross-industry gaming signals to detect bonus abuse and fraud at first contact | Gaming-specific fraud controls targeting multi-accounting, ATO, and bonus abuse | Fraud detection across identity, device, and network signals to deter multi-accounting and coordinated attacks | Focus on bonus abuse, multi-accounting, affiliate fraud, supported by biometrics and human review |

GBG Go by GBG is an all-in-one identity platform built to help businesses connect safely with every genuine identity in the world, combining identity verification, risk signals, and fraud intelligence through a single API and configurable journeys.
For online gambling compliance, GBG’s strengths are typically threefold:
Atlantic Lottery, for example, improved its pass rate from 68% to 82%, and manual verification calls were reduced by at least 30% thanks to the company’s collaboration with GBG.
“The way data is presented and used is very smart and the expert personal support I receive from GBG is top notch. They collaborate on proof of concepts and cost/benefit analysis with every change we make. I don’t see GBG as a vendor, it’s a very strong strategic partnership,” said Adam MacLeod, Digital Product Manager at Atlantic Lottery.

Notable capabilities include:

Core capabilities include:
iDenfy is a good fit if: you want straightforward integration, clear pricing models, and strong document and biometric verification.
There is no single “best” KYC software for online gambling. When choosing the right provider, remember that the real goal is to reduce regulatory and fraud risk without damaging player experience.
The most effective operators apply a layered, risk-based approach:
When implemented well, KYC stops being a bottleneck. Instead, it becomes an enabler of compliant growth and long-term player trust.
