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.
