What this service does

Cybersecurity expert witness for commercial litigation. FRE 702 Daubert-survives methodology. Hash-verified evidence.

Engagements are confidential and structured to begin within 48 hours of the consultation. Some service tracks are offered at a fixed fee; complex investigations are billed hourly with a clear scope, milestone updates, and a cap agreed up front. Quinn leads every engagement directly; the senior engineers on her team execute the technical work alongside her. No sales pipeline. No off-shoring. No black-box delivery.

What we will not do

How an engagement begins

  1. Confidential consultation. NDA-protected. 30-60 minutes. Direct conversation, no sales process.
  2. Scoped engagement. Written proposal with defined deliverables and pricing — fixed fee where it applies, hourly with milestone caps for open-ended investigations.
  3. Investigation and findings. Court-admissible standards. Written report you can act on.

Available as a referral or white-label engagement

We work with cybersecurity firms, MSPs and MSSPs, IT consultancies, law firms, breach counsel, and insurance brokers who need our capability without building it in-house. Two structures are available depending on what fits your relationship with the client.

We protect partner relationships. We do not solicit your client outside the scope of the engagement, we do not name them publicly without written consent, and we sign whatever non-circumvention language your counsel requires.

Why this work matters

Targeting expert witness cybersecurity. 17 active credentials across the practice (across GIAC, Offensive Security, AWS, Splunk, CompTIA) — methodology trusted by Fortune 50 enterprises, defense contractors, and the attorneys who refer to us.

How We Work

A confidential, structured engagement.

01

Introduction

A first conversation with Quinn directly. No sales pipeline, no junior account staff. We talk about whether the partnership is the right fit, both ways.

02

Diagnostic

Four to eight weeks. We look at IT, security, and AI together. The output is an honest map of the modernization work — what to do, in what order, with what budget.

03

Partnership

Six-month minimum, typically multi-year. We become the operating partner — accountable, single contract, senior practitioners, knowledge transfer contractual.

Reviews

From the senior people
who’ve worked alongside Quinn.

The named companies beside each reviewer are their employers — not Varcoe partnerships. Each quote is a professional reference from someone who’s shipped work alongside Quinn directly.

The partnership model isn't marketing language with Quinn — it's how she actually works. Senior judgment, single accountable contact, and the rigor to integrate across IT, security, and AI under one roof.

Aaron Birnbaum

Managing Partner

Seron Security
Quinnlan brings more than expertise — she brings strategic alignment. The ability to scale operations without sacrificing depth is exactly what serious organizations need from a modernization partner.

Caroline Lombard

Threat Specialist

aws
I've worked with Quinnlan on incidents most teams couldn't navigate — Log4j among them. The technical depth and the calm under fire are real, and they're rare.

Justin Cox

Senior AWS Security Analyst

PayPal
One of the most seamless collaborations I've had in this industry. Composure under pressure, technical precision, and the kind of credibility that compounds — exactly the senior bench a modernization partnership needs.
