Security Audit

Compliance is not security.
No shortcuts. No blind spots.

Don’t let a data breach become your first security audit

  • Before a major launch

    Validate security before new code reaches users.

  • After an architecture change

    Reassess new services, permissions, and trust boundaries.

  • Ready for an enterprise review

    Bring clear evidence to customer security reviews and diligence.

  • After a security incident

    Confirm whether a reported issue is exploitable — and what it can reach.

What we audit

  • Operating System

    Kernel, drivers, and core services — where memory-safety flaws and privilege escalation begin.

    • Linux kernel
    • Windows
    • Embedded and firmware

  • Browser

    JavaScript engines, sandboxes, and renderer boundaries — where a browser bug becomes code execution.

    • Chrome / V8
    • Firefox
    • QuickJS

  • Web Infrastructure

    Applications, APIs, and identity flows — tested for exploitable paths, not theoretical risk.

    • Web apps
    • APIs and authentication
    • Custom backends

  • Solidity

    Smart contracts that move funds — tested for flawed permissions, upgrade paths, and economic logic.

    • DeFi protocols
    • Token contracts
    • Upgradeable proxies

  • Agentic Infrastructure

    MCP servers, tool sandboxes, and agent APIs — where prompts can become permissions, code execution, or data loss.

    • MCP servers
    • Agentic browsers
    • Tool sandboxes

  • EVM (Ethereum Virtual Machine)

    Bytecode, compiler output, and runtime behavior — where on-chain execution can diverge from source-level assumptions.

    • EVM bytecode
    • Compiler output
    • L2 and EVM chains

From scope to verified findings.

  1. 1Scope

    A short call maps targets, threat model, and timeline before work begins.

  2. 2Reconnaissance

    Attack-surface enumeration: entry points, trust boundaries, and the code paths that actually matter.

  3. 3Hunt

    Senior researchers and Nebu work on the same codebase — manual review for logic, the AI pipeline for scale, and fuzzing where it is effective.

  4. 4Validate

    Every finding is exploited or reproduced before it is written down. No speculative severity.

  5. 5Report and retest

    Root cause, impact, and remediation guidance your engineers can act on — plus retesting after patches land.

An answer for today.
