About Census Networks

We're building the verification layer for the employment-as-attack-surface era.

Census Networks treats employment as a supply-chain control. Our job is to make every employer able to reason about candidate risk the way modern security teams reason about every other control.

Mission

Close the structural seam between security and HR.

The capabilities to detect employment fraud already exist as point tools, owned by different teams, none of them reasoning about the joint pattern. State actors and financial fraudsters are very good at finding that seam. We are building the orchestration layer that closes it, and we are doing it in the open, with explainability, human-in-the-loop, and shared-defense by design.

The founding insight

The adversary is reasoning about the joint defense. The defense has to do the same.

A sophisticated adversary does not attempt to fool any single tool. The known facilitator playbooks include coaching on which background-check vendors specific employers use, which OSINT signals to plant in advance, and which interview platforms can be defeated by which face-swap stack. The adversary is reasoning about the joint defense and finding the seam. The defense has to do the same. That is the company in one sentence.

Who we are

Leadership.

Census is led by operators who have spent their careers at the seam between security, HR, and enterprise technology — the exact seam the company is built to close.

Rebecca Brown
Chief Executive Officer

Rebecca Brown brings more than two decades of experience at the intersection of people operations, enterprise technology, and data governance — a background that reflects a conviction central to Census Networks: that HR systems are security infrastructure. The platforms that onboard employees, verify identities, and hold workforce data are among an enterprise's most sensitive assets, and Rebecca has spent her career building and protecting them at global scale.

Since 2024, Rebecca has served as Founder and Principal Consultant of RB Technology Consulting, acting as fractional CHRO and strategic advisor to startups and mid-market companies on HR transformation, AI implementation, org design, IPO readiness, and globalization. Her engagements have included one of the best-funded companies in the ransomware protection space and leading HR initiatives at several publicly traded pharmaceutical and technology companies — work that placed her directly at the seam between workforce operations and enterprise security.

Previously, Rebecca was Senior Director of People Technology and Operations at Guardant Health, where she led the company's global HR technology roadmap, directed a full Workday re-implementation spanning more than fifty integrations, and delivered GDPR and SOX compliance milestones on Board-level timelines. Her shared-services model for employee support sustained a 99% employee satisfaction rating over eighteen months of continuous monitoring.

Before Guardant, Rebecca spent six years at BD (Becton Dickinson), leading global HRIS strategy and the HR program management office for M&A activity covering more than 80,000 employees in over 70 countries — including 40+ acquisitions, two mergers, and three divestitures. She previously led the HR technology integration of BD and CareFusion, and earlier held operations and analytics leadership roles at Cerner Corporation, including on-site client operations leadership for Palomar Health.

At Census Networks, Rebecca applies this experience to a new frontier: helping enterprises defend the employment lifecycle itself, where identity, trust, and workforce data converge — and where the next generation of security threats is already emerging.

Matt Harrigan
Chief Strategy Officer

Matt Harrigan has spent three decades on the offensive side of cybersecurity — breaking into systems, studying how attackers think, and building companies that turn that knowledge into defense. It's exactly this attacker's-eye view that drives Census Networks: you can't eradicate employment fraud, deepfake interviews, and infiltration campaigns unless you understand precisely how those attacks are built and executed.

Matt's career began in the early days of the commercial internet, engineering distributed systems at SAIC — where he advised executive leadership on the acquisition of the InterNIC, the business that became Network Solutions — and building enterprise management systems at Cisco. In 1996, he founded MCR, one of the world's first information security consultancies and the first managed security services provider, a milestone that landed him on the cover of Forbes that year.

As Vice President of Consulting at Trustwave, Matt worked with the world's biggest brands to secure their environments against a rapidly evolving threat landscape. He then served as President of NSS Labs, the independent security testing laboratory, where he evaluated virtually every security product on the market — gaining an insider's understanding of how the industry's defensive technology actually works, and where it falls short.

Matt went on to lead a series of security companies as CEO, including PacketSled, a breach detection and network forensics platform, and has run Critical Assets, his information security consultancy serving high tech, energy, healthcare, and the public sector, since 2008. Most recently, he served as Field CISO and Managing Director at Praetorian.

Matt is also an active investor in early-stage AI startups and lives in San Diego, where he founded Census Networks to defend the one attack surface every company shares: the people it hires.

Brett Eisenberg
Chief Technology Officer

Brett Eisenberg brings over three decades of experience spanning cybersecurity, enterprise technology, and executive leadership to Census Networks. He began his career as a security and systems architect in the 1990s, serving as Senior Security Architect at The Root Group and Systems Architect at Scient, where he designed secure infrastructure for enterprise clients during the formative years of the commercial internet.

Brett went on to hold technology leadership roles at 12 Entrepreneuring, Acumen Sciences, and Innovation Investments before becoming CTO of Five Across, a community platform acquired by Cisco Systems in 2007. Following the acquisition, he led engineering teams at Cisco, guiding the integration and evolution of the platform inside one of the world's largest networking companies.

In 2009, Brett stepped into the CEO role at Triple Aught Design, where he spent nearly fourteen years leading the company through sustained growth across product, operations, and direct-to-consumer commerce. Most recently, he served as Chief Product Officer at CODEWORD Brands, overseeing product strategy and technology.

At Census Networks, Brett draws on this rare combination of deep security roots and executive operating experience to lead the engineering of the company's platform for securing the employment lifecycle.

How we work

Five principles run through the platform and the company.

  1. 01

    AI-first reasoning across signals.

    Judgments are formed from joint patterns, not single artifacts.

  2. 02

    Model independence.

    No single model dominates. An adversary cannot defeat the platform by defeating one component.

  3. 03

    Full lifecycle scope.

    Candidates are monitored from application through continuous post-hire; the moment of hire is not a hand-off out of risk visibility.

  4. 04

    Adversarial robustness through fault-tolerant consensus.

    When signals disagree, the platform errs toward caution and routes to human review.

  5. 05

    Explainability.

    Every score decomposes into the evidence that produced it. No black boxes in the decision path.

What we are working on now

Census is in the development-partner phase of 2026.

We are running pilots with a small set of security vendors and enterprise employers, refining the platform against live adversarial conditions, and convening the working group around our cross-industry signal-sharing proposal. The roadmap is real, the calendar is real, and we publish what we measure.

Press and contact

We welcome the opportunity to brief security and HR leaders bilaterally, and to present at industry convenings.
