Austin Comstock — Independent Security Consultant

Career

The Story

NetApp

Software Engineer → Cloud Engineer · 2012–2016

Built the engineering foundation — distributed systems, cloud architecture, and production infrastructure. Most red teamers don't know how the target was built. I helped build targets like it.

Amazon Web Services

Red Team / Penetration Testing Engineer · 2016–2020

Started pentesting individual services before launch. Results led to a promotion to red team the entire AWS ecosystem — the cloud that powers the majority of the internet and U.S. government infrastructure.

Oracle Cloud Infrastructure

Senior Offensive Security Engineer · 2020–2021

Hired to red team OCI. Built lateral movement frameworks that mapped attacker paths across the cloud. Created the API auto-discovery framework that became OCI's #1 security investment priority.

US Patent Application (Lead Inventor) · Catalina API Security Testing Framework

Coinbase

Senior Security Engineer · 2021–2022

Brought in to secure the exchange that moves billions. Automated 75%+ API authentication and authorization coverage in a single engagement.

Zoom

Senior Offensive Security Engineer · 2022–Present

Built a Kubernetes vulnerability discovery platform. Executive recognition. Independently prevented multiple customer data exposure incidents.

How to Engage

Security testing is undifferentiated work for your team. You shouldn't have to manage it. Start an engagement in whatever way is easiest for you — I take care of everything from scoping to delivery.

Your AI Agent

Point your OpenClaw, Claude, or any AI agent at the discovery manifest. It can evaluate capabilities, compare pricing, and initiate an engagement — start to finish — without you lifting a finger.

→ /.well-known/ai.json

API

One POST request. Partial submissions accepted — send whatever you know, get a reference ID back. Come back with more details when you have them. Progressive, zero-friction intake.

POST /api/hire
Content-Type: application/json

{
  "capability_id": "external-pentest",
  "tier": "standard",
  "scope": {
    "domains": ["example.com"]
  },
  "contact": {
    "name": "Jane Smith",
    "email": "jane@example.com",
    "company": "Example Corp"
  }
}

Book a Call

30-minute discovery call. Tell me what you're trying to protect, I'll tell you exactly how I can help. No sales pitch — just a conversation between security people.

→ Book a Discovery Call

Describe what you need. Scope, timeline, what you're trying to protect. I'll respond within 24 hours with a fixed-price proposal.

→ austin@austincomstock.ai

All engagements require written authorization from the system owner before testing begins. I verify authorization before any work starts.

The companies that run the internet hired me to break them.
