Unity Game Penetration Testing
In a game the attacker owns the client entirely, which changes the question. Not whether they can read your code, they can, but whether your server believes what the client tells it about scores, purchases and inventory. CREST-certified testers, fixed price from £3,140, scoped in 24 hours.
- Unlimited retesting
- No rescheduling or cancellation fees
- Fixed quote within 24 hours
“I would highly recommend EJN Labs to any organisation seeking reliable, detailed, and well-managed penetration testing services, particularly for government or enterprise-level projects.”
Imran SaghirProject Lead, SquareOne“There wasn’t another company we could find that could deliver what we needed in the timeframe we needed. The client loved it, and we got instant ROI from the engagement.”
Dan WilcocksonCo-Founder, CelloriGames ship the client to the player and the player may modify it freely. That is not a flaw to be fixed, it is the operating condition, and the security question is which decisions the server delegates to a client it cannot trust.
Why client trust is the whole vulnerability class
The commercially damaging findings follow from that. Currency and inventory changes accepted from the client, scores submitted without validation, and in-app purchases granted on an unverified receipt, which is effectively a free shop for anyone who reads the traffic.
Then there is the data side. Games collect player accounts, often from minors, and a leaderboard or friends API that returns more than it should is a data protection question as much as a game integrity one.
ISO 27001, SOC 2, PCI DSS and Cyber Essentials Plus audits accept manual penetration test evidence. Scan-only evidence is generally insufficient.
ASSEMBLIES, PURCHASES + SERVERS
What we actually pen test on a Unity title
Manual pen testing across assembly and asset extraction, client-authoritative logic, in-app purchase validation, multiplayer traffic and the backend behind the game.
Assembly and asset extraction
IL2CPP and Mono builds unpacked, assemblies decompiled for keys, endpoints and logic, asset bundle extraction, and whether encryption on bundles or save data is meaningful or ornamental.
Client authority and state
Which state the server accepts from the client, currency, inventory, progression and score submission validation, and whether a modified client can grant itself anything of value.
In-app purchase validation
Whether receipts are verified server-side against the store, replay of a valid receipt across accounts, whether entitlements can be granted without a purchase, and refund handling.
Multiplayer and network traffic
Protocol inspection and manipulation, whether the authoritative server validates movement and actions, matchmaking and lobby abuse, and whether a player can reach another player’s session data.
Accounts and player data
Authentication and account linking, whether one player can reach another’s profile or messages, leaderboard and friends API scope, and what personal data the client transmits.
METHODOLOGY
Unity Game Penetration Testing: From Scope to Attestation
CREST-aligned methodology built on OWASP Web Security Testing Guide, OWASP ASVS, NIST SP 800-115, and PTES. Each finding maps to all four standards plus your specific compliance regime.
Reconnaissance
Application mapping, technology fingerprinting, content discovery, parameter enumeration, authentication-flow analysis, role-matrix construction.
Vulnerability Assessment
Authenticated and unauthenticated automated scanning across every user role, plus targeted manual checks for known weakness patterns.
Manual Exploitation
Hands-on testing by a CREST-certified pentester. Business-logic exploitation, chained vulnerabilities, privilege escalation, impact validation.
Reporting + Retest
Executive summary, technical report with CVSS scores and reproduction steps, walkthrough call, free retest after remediation, attestation letter.
CREDENTIALS
Verified Accreditations Auditors Accept
Every credential below is independently verifiable. UK procurement teams, FCA supervisors, ISO 27001 / SOC 2 auditors, and cyber insurance underwriters all recognise these standards.

FAQ
Frequently Asked
Is this different from a normal mobile app test?
The techniques overlap and the emphasis is different. A banking app test assumes the client is mostly honest. A game test assumes it is not, and concentrates on what the server validates rather than what the client protects.
Do you test PC and console builds too?
PC builds yes, and mobile is the most common request. Console testing depends on the platform holder’s rules and we will tell you honestly what is and is not feasible before you commit.
Will you ban our test accounts?
We use accounts you provision on an environment you nominate, ideally a staging backend. Nothing we do touches live player accounts unless you specifically ask for a production test.
What do we receive?
A report covering game integrity and security findings separately, mapped to the OWASP Mobile Top 10 and GDPR where player data is in scope, plus a developer write-up and unlimited free retesting.
