The Klaus Project, LLC · Software & Cybersecurity

Security engineering for the AI era

We audit, harden, and red-team the LLM and agent systems your business depends on. Built by engineers who run their own.

What we do.

Focused engagements for companies deploying AI in production, plus secure-by-default custom software development for teams without a dedicated security hire.

01 / Code review
$499 · 5 days

AI Code Review

A focused security review of one AI-related code change or feature — up to 500 lines, or a single PR/feature. Written findings on prompt injection, tool privilege, and context leakage. Trial-size engagement; perfect first step.

Single PR Pre-launch sanity check 5 business days
02 / Audit
$2,500 · 1 week

AI Security Quick-Audit

One AI feature or agent system, fully reviewed. Findings across the three core categories: trusted-channel injection, tool privilege drift, context bleed. Severity-ranked report with remediation guidance and a debrief call.

Single product surface ~16 hours of focused review
03 / Threat model
$4,500 · 10 days

Agent Threat Model

For teams building an agent system who want it modeled before they ship, not after. Trust-boundary analysis, privilege flows, blast-radius mapping, and concrete recommendations on tool design, sandboxing, and approval gates.

AI Security Deep-Dive

The full version — for companies with multiple AI features or higher stakes (B2B SaaS with AI, regulated industries, sensitive data). Up to 3 product surfaces, threat model document, live red-team session, code-level remediation playbook, 30-day follow-up.

Custom Software Development

Production applications built secure-by-default. Mobile, desktop, and web — across Unity, .NET MAUI, Android (Kotlin/Java), and modern web stacks. Security and reliability baked in from the first commit, not bolted on at the end.

Mobile Desktop Web Game dev
06 / Retainer
From $3,000/mo

Security Advisor Retainer

For companies that want ongoing access to security expertise without hiring a full-time security engineer. ~16 hours/month of code review, architecture consults, and ad-hoc questions, with 1-business-day response time.

Ongoing access Slack/email same-day

We don't just audit AI. We build it.

Most security firms have never shipped a production agent. Most ML teams have never written a threat model. We sit in the overlap — and that's the only place this work can be done well.

The systems we've built in-house aren't side projects. They're the same architectures your team is racing to deploy, which means we know where they break before you do.

See the full portfolio at /labs/ — agent systems, fine-tuned models, and shipped consumer apps.

  • Forge Agent Orchestration

    Production agent system featuring snapshot rollback, file-lock management, circuit breakers, streaming hub, and auto-verification. Live across CLI, VS Code, and desktop interfaces.

  • Klaus Custom LLM

    Fine-tuned local language model served via REST API. Designed and operated end-to-end on a self-hosted inference stack — the same kind of deployment we audit for clients.

  • Mirror Shipped Product

    A production D&D AI assistant on Android, running on the same self-hosted Klaus inference stack. Real users, real load, real failure modes — the kind of operational experience most security consultants don't have.

  • Founder background Credentials

    Bachelor's in Cybersecurity. Hands-on engineering across Unity, .NET MAUI, Android (Kotlin/Java), and game-server architecture. Solo-built every system listed above.

From the engineering log.

Three Attack Categories Every AI Agent Inherits

Every company shipping an AI agent right now is shipping the same three vulnerabilities. Not because their engineers are careless, but because the architecture itself guarantees them. The structural map: trusted-channel injection, tool privilege drift, context bleed.

A small firm, by design.

The Klaus Project, LLC is a software and cybersecurity consultancy. We work primarily with companies deploying AI systems and small-to-mid teams that need security expertise without a full-time hire.

We're deliberately small. That means engagements are run by the engineer doing the work, not handed off to a junior. It also means we say no to projects we're not the right fit for — which is the only way to consistently be the right fit for the ones we take.
