ABOUT US

Change things. Don't just survive them.

That's the WestGate mission. We build infrastructure that lets risk-averse enterprises modernize the systems they can't afford to break. Churchill contains config drift, external attacks, and insider threats by design, and keeps critical systems compliant as legacy modernization pressure mounts. It installs in moments, manages simply, and handles the rest.

Every unapproved action is diverted, recorded, and logged. Over time, our customers grow their own threat intelligence, specific to their systems and no one else's, built from exactly what was attempted against them.

The team has worked together for years on flagship executive projects. The history is real.

FOUNDER'S CAREER ARC

Twenty-two years of practitioner experience behind the mission.

Cheryl Westgate refined this mission (governance at the mandatory passage point, repair before enforce) across four roles before founding WestGate Data Science. The mission is hers. Churchill is the first product built on it.

2003
Banking
Recognized the compilation step handoff as the right intervention point. The origin insight.
2010s
Healthcare
Applied the mission to operational policy across regulated clinical and pharmacy systems.
2018
Supply Chain
Extended the mission to global procurement and category management at enterprise scale.
2026
Churchill's Protocol
The mission compiled into kernel-level infrastructure. The first WGDS product.
THE TEAM

Built by the people who hold the mission.

Five co-founders. Two engineers. Every member chosen for what they bring to the architecture, the operations, or the rooms we need to be in.

HOW WE TESTED IT ON OURSELVES

Before we would ever ask a client to take on that risk.

We put Churchill through two adversarial programs before opening a single design pilot conversation. Our product, our risk. The numbers below are the combined evidence record from both programs.

Public CTF March 10 – April 10, 2026

30-day kernel offensive

  • 31 offensive kernel researchers
  • 40 autonomous AI sessions, full root from start
  • 200+ attack techniques attempted
  • $10K bounty. Unclaimed
  • 0 kernel breaches
Anthropic Cyber Verification Program Mythos adversarial engagement

Frontier AI

  • 29 sessions documented
  • 11.3 cumulative hours of adversarial activity
  • 406,433 enforcement decisions
  • 3+ sessions starting with full root
  • 22 tamper actions during root sessions. All blocked
Combined result

100% containment. Zero persistent modifications. Zero exfiltration.

1,713 forensic recordings preserved. Watchable, searchable, cryptographically signed. Every blocked attempt became part of the evidence record.
