Practice · Managed Security

A real security operation.
Not an alert factory.

MSSP for mid-market — 24/7 SOC, managed detection and response (MDR), threat hunting, threat intelligence, detection engineering, IR retainer, vCISO. Senior practitioners on every alert. Containment authority pre-negotiated — we pull the host off the network at 2am, we don’t email and ask. Detection engineering is a real practice, not vendor defaults with your name on them.

$25K-$100K/month programmatic · MDR + SOC + IR + vCISO bundled · senior on every alert

What we run

Fifteen components. Senior on every alert.

24/7 SOC + Monitoring

Senior analysts on every alert. P1 detection→containment in 15 min. No tier-1 black-box. Average analyst tenure disclosed at QBR.

MDR — Managed Detection & Response

Endpoints (CrowdStrike Falcon, SentinelOne, Defender), identity (Push, Permiso), cloud (Wiz, Lacework), SaaS (Push, Adaptive Shield, Obsidian), email (Abnormal, Material). Containment authority pre-negotiated.

SIEM + Detection Engineering

Splunk / Sentinel / Chronicle. Custom rules tuned to your environment, MITRE ATT&CK-mapped, versioned in Git, peer-reviewed. Detection-as-code.

Threat Hunting

Hypothesis-driven, monthly cycle. Findings convert to permanent detections. Insider threat hunts for regulated-data partners.

Threat Intelligence

Vertical-specific briefings, dark web monitoring of your domains/execs/repos, brand monitoring (typosquats, deepfake watch), vendor breach monitoring.

Vulnerability Management

Continuous scanning (Tenable, Qualys), CSPM (Wiz), SAST/SCA, exploitability-aware prioritization (KEV, EPSS). We patch what we manage. Quarterly external pentest + annual full-scope.

Incident Response Retainer

48-hour engagement start. Insurance-carrier-accepted (AIG, Beazley, Coalition, Resilience, Travelers, Chubb, Munich Re Hartford). Ransomware-, BEC-, insider-, cloud-IR ready. Counsel-coordinated.

SOAR + Automation

Tines / Torq / Splunk SOAR. Automation only where the human cost is high and risk of automation error is low. Human approves contain-and-isolate on production.

vCISO + Governance

Quarterly risk reviews, board-readable reports, policy framework, vendor risk management, security committee facilitation.

Compliance Evidence Collection

SOC 2 Type 2, HIPAA, CMMC, ISO 27001, PCI, FedRAMP, NIST 800-171. Continuous, not annual. Auditor pre-coordinated.

Identity Threat Detection (ITDR)

Push, BeyondID, Permiso, native Entra ID Protection. Impossible travel, OAuth abuse, MFA fatigue, session hijack, dormant account re-activation.

Email + DLP

Beyond M365 / Workspace defaults. Abnormal, Material, Sublime, Tessian for AI-aware phishing. Microsoft Purview / Google DLP tuned to your data classes.

CSPM / CWPP / CIEM

Wiz, Lacework, Prisma Cloud, native cloud (Security Hub + Defender + SCC). Kubernetes admission control + runtime detection. IaC scanning before merge. Drift detection.

Tabletop + Simulation

Twice-yearly scenario tabletops. Annual live red-team simulation. Quarterly phishing campaigns with realistic role-targeted pretexts.

Cyber Insurance Liaison

Carrier-coordinated underwriting, continuous evidence package, policy-aligned MDR, renewal premium negotiation, post-incident carrier coordination. We work alongside your broker with AIG, Beazley, Coalition, Resilience, Travelers, Chubb. See the dedicated cyber insurance page.

Why MSSP 2.0 still feels like MSSP 1.0

We contain.
We don’t alert and hope.

Containment authority is in the engagement charter.We can pull a host off the network at 2am without asking. Most MSSPs won’t commit to that contractually because their business model is alerts-billed, not containment-billed.

Senior on every alert. The analyst who triages your alert can investigate and respond it themselves. No tier-1 black-box, no internal ticket-routing maze.

Detection engineering is a real practice. Custom rules written for your environment, mapped to MITRE ATT&CK, versioned in Git, peer-reviewed before promotion. Quarterly coverage report tells you which TTPs are covered, partially covered, or blind. Not vendor-default rules with your name on them.

Insurance-accepted IR retainer. Major underwriters know us. AIG, Beazley, Coalition, Resilience, Travelers, Chubb, Munich Re Hartford — pre-vetted. Faster underwriting, better rates.

Sub-15-minute MTTR target on P1. Stated. Tracked. Reported quarterly. Delivered.

Pricing

Premium MSSP economics.

Inside the partnership: bundled into the $500K-$1M-$3M/year envelope.

MSSP stand-alone: $30K-$120K/month programmatic, with per-endpoint volume add-ons at $15-$25/endpoint/mo for high counts.

IR retainer: pre-paid hour bank, replenished annually. Declared-incident hourly $500-$700/hour for senior IR — within market band; insurance carriers pay this rate to us as readily as to Mandiant.

vCISO: bundled inside MSSP partnership; stand-alone retainer $10K-$25K/month for mid-market boards.

Six months minimum, multi-year typical for security partnerships. Schedule directly or call.

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.
