Smart Contract Security Audit
In Web3, code is money — and bugs are irreversible. Our auditors combine manual review with tooling to find the vulnerabilities that lead to drained funds and broken logic, before your contract goes live on-chain.
DeFi Protocol Security Audit
DeFi protocols combine complex contracts, economic incentives and composability — a rich attack surface. We audit the whole system, from contract code to economic design to oracle dependencies, so your protocol can hold value safely.
Web3 Application Penetration Testing
A dApp is more than its contracts — it's front-ends, wallets, APIs and integrations, each a potential weak point. We test the whole Web3 application stack so users interacting with your protocol stay safe end to end.
Wallet Security Testing
Wallets are where crypto security lives or dies. We test wallet software and hardware for key-handling flaws, insecure storage and transaction-signing weaknesses, so the wallet you build — or rely on — truly protects the keys.
Digital Wallet Security Scan
A fast, focused security check for your own crypto wallet. We review your wallet's exposure, risky token approvals and interaction history, and give you clear steps to reduce risk — consent-based, for wallets you control.
IoT Security Testing
Connected devices multiply your attack surface fast. We test IoT devices and their ecosystems — hardware, firmware, apps and cloud — for the weaknesses that let attackers hijack devices or use them as a way into your network.
Firmware Security Analysis
Firmware is the code beneath the software, and it's often the least scrutinised. We analyse device firmware for hardcoded secrets, insecure update mechanisms and exploitable flaws, securing the layer attackers love because no one else looks.
SCADA/ICS & OT Security Assessment
Operational technology runs the physical world — and downtime or safety failures aren't options. We assess your SCADA, ICS and OT environments with a safety-first methodology, finding risk without ever disrupting critical operations.
Threat Modelling Workshop
Understand your threats before you build defences. In a collaborative workshop, we work with your team to map what could go wrong, who would attack you and how, and where to focus — turning security from guesswork into strategy.
Security Consultation
Sometimes you just need an expert to talk to. Book time with a senior security consultant to work through a challenge, review a decision, get a second opinion, or plan your next steps — practical advice, no long engagement required.
Vulnerability Assessment
A thorough, expert-validated assessment of the vulnerabilities across your systems, prioritised by real risk. The efficient way to understand your exposure and know exactly what to fix first — the ideal starting point for many organisations.
AI/ML Security Assessment
You shipped an LLM feature; attackers shipped prompt injections. We test AI systems the way adversaries do — injection, jailbreaks, data leakage, tool abuse, poisoning paths — across the full stack: the model integration, the pipeline that feeds it, and the application around it.
Post-Quantum Readiness Assessment
Adversaries are harvesting encrypted traffic today to decrypt when quantum computers mature — so data with a long secrecy lifetime is already at risk. We inventory every place your organisation uses cryptography and build a pragmatic, standards-aligned migration path to post-quantum algorithms.
Crypto Exchange & Custody Security Assessment
An architectural and operational review of how an exchange or custodian actually moves value — hot/cold separation, withdrawal authorisation, key-management design and the admin paths that turn a small compromise into a total loss.
Blockchain Node & Validator Infrastructure Security
Security review of the infrastructure your chain participation depends on — validator key isolation, RPC exposure, host hardening, monitoring and the availability engineering that keeps slashing and downtime off your balance sheet.
Token Launch & Web3 Security Readiness
A pre-launch readiness review covering the things that go wrong on day one — admin privileges, upgradeability, oracle dependencies, deployment process and whether anyone is actually watching after the launch window closes.
Web3 Incident Response & Recovery Advisory
Authorized defensive response to an on-chain incident: reconstructing what happened from public transaction data, containing further loss, preserving evidence and coordinating with exchanges and providers — without ever promising funds back.
