iGaming & Online Gambling Penetration Testing

We start by mapping the real attack surface: player-facing site, mobile API, affiliate and back-office portals, provider callbacks, and any staging that leaked into production. Using Burp Suite, nmap and ffuf we enumerate endpoints, then sit down with your team to understand the money flows. A quick threat model of who profits from breaking each flow tells us where to spend the hours.

This is where an iGaming test earns its keep. We register real player accounts across roles and jurisdictions, then attack the logic: can a stake be altered after an event starts, can a withdrawal be triggered before wagering requirements clear, can two concurrent requests both debit the same balance? We test bonus terms line by line, trying to hold a bet on both outcomes, chain reloads, and cash out promotional funds that were meant to be locked.

A finding is only worth reporting if we can show the impact. When we find a race condition in the wallet, we prove it by moving a real (test) balance beyond what the rules allow and capturing the request set that did it. Every issue gets a working reproduction, not a theoretical note, so your developers can replay it and confirm the fix.

You get a written report within days of the test window closing, and we walk your team through it live. After you remediate, we retest the reported issues at no extra cost to confirm the fixes hold and did not open something new.

Concurrent deposit, transfer or withdrawal requests that are not wrapped in a proper transaction or lock let a player spend the same balance twice. We fire timed parallel requests at settlement and cash-out endpoints and watch for balances that go negative or credits that duplicate. This is one of the highest-value bugs on any gambling platform and one a vulnerability scanner will never catch.

Bonus-abuse testing is a core part of the work. We look at whether welcome offers can be farmed through disposable emails, whether self-referral loops pay out, whether rollover requirements can be dodged by betting on near-guaranteed outcomes, and whether promotional balance can be withdrawn as cash before it is cleared. Operators lose real margin here every month, quietly.

We test whether a stake, odds value or game result can be tampered with in transit, whether late bets slip through after an event locks, and whether a losing round can be replayed or cancelled from the client. On live-dealer and RNG-driven games we check that outcomes are authoritative on the server and never trusted from the browser.

Regulators care about who is allowed to play, and so do we. We attempt to register from blocked jurisdictions by defeating geofencing, to re-enter after self-exclusion under a slightly altered identity, and to pass KYC with reused or manipulated documents. A self-excluded player who gets back in is both a compliance failure and a genuine harm.

Weak password-reset tokens, sessions that survive a password change, and second-factor prompts that can be skipped all lead to player account takeover. Once an attacker owns an account with a funded wallet and stored payment method, the loss is direct.

The callback interfaces between your platform and game providers are trust boundaries that are often under-tested. We check signature validation on provider callbacks, whether win notifications can be forged, and whether the aggregator API exposes other operators’ data through weak tenant isolation.

We are familiar with the technical security expectations of the Malta Gaming Authority (MGA), the UK Gambling Commission, and GLI standards such as GLI-19 for interactive gaming systems and GLI-33 for event wagering. Where your licence calls for independent security testing of the platform, our report and attestation letter are written to answer that requirement directly.

Because you handle card deposits and stored player funds, PCI DSS 4.0 applies to your payment paths, and requirement 11.4 specifically calls for regular penetration testing of the cardholder environment. Player identity and betting history are personal data, so we also test with GDPR obligations in mind, and DORA now shapes operational-resilience testing for regulated financial and betting entities across the EU.

Underneath the gaming-specific work we still measure against OWASP ASVS and the OWASP Top 10, and for the mobile clients against OWASP MASVS. These give your engineers a common, well-understood language for the fixes.
