Simplicity IT MSSP: Modern SecOps with Unified Platform for Sentinel and Defender XDR

Built for the CISO or SOC manager who cannot staff a 24x7 rota and is carrying alert backlog they know contains a real incident. This engagement will cut mean time to respond and eliminate the overnight coverage gap without hiring a night shift.

Who this is for

Mid-market and enterprise security teams of two to fifteen people who already own Microsoft 365 E5 or the Defender suite and are not extracting the detection value they paid for. The buying committee is usually the CISO who owns the risk, the IT Director who owns the tenant, and a compliance officer who needs evidence for an audit or a cyber-insurance renewal. If your team is triaging alerts during business hours and hoping nothing lands at 2am, this service is built for that gap.

What we deliver

• 24x7x365 monitoring and triage by named analysts, running in your Microsoft Sentinel workspace so the data and the detections stay under your tenant and your retention policy.
• Detection engineering: tuned analytics rules, suppression of the noise that trains teams to ignore alerts, and MITRE ATT&CK coverage mapping reviewed each quarter.
• Incident response with a 15-minute triage SLA on critical severity, containment actions agreed in a written runbook, and a post-incident report within five business days.
• Monthly proactive threat hunting plus a service review with the metrics that matter: dwell time, MTTR, alert volume, and coverage gaps closed.

Outcomes our customers see

One 1,400-seat professional services customer cut mean time to respond from 6.5 hours to under 2 hours, a 71 percent reduction, within the first 90 days. Alert tuning removed 78 percent of false positives in the first 60 days at a regional health system, taking the analyst queue from roughly 400 to 88 alerts per day. Across the customer base, 100 percent of critical-severity alerts have met the 15-minute triage SLA over the last 365 days.

How this compares

Most MSSPs move your telemetry into their own SIEM, which means you pay twice for ingestion, you cannot audit the detections, and you lose the data the day you leave. This service runs inside your Sentinel workspace: you own the rules, the history, and the exit. Compared with a pure tooling deployment, you get named analysts who know your environment rather than a queue, and compared with building in-house, you reach 24x7 coverage without recruiting three additional shifts.

Architecture and Microsoft alignment

The deployment architecture is a customer-tenant Microsoft Sentinel workspace with Defender XDR connectors for endpoint, identity, email, and cloud apps, Microsoft Entra ID as the identity signal source, and Defender for Cloud posture data joined in. Simplicity IT analysts access it through Azure Lighthouse delegated resource management, so access is scoped, time-bound, and fully logged in your tenant. Automation runs on Sentinel playbooks and Logic Apps under your subscription. No telemetry is copied to a third-party platform. Aligned to the Microsoft solution plays Modern SecOps with Unified Platform and Data Security.

Plans

Plans, prices, and full scope per plan are on the Plans tab of this listing.

Prerequisites

An Azure subscription with an existing or new Microsoft Sentinel workspace, Microsoft 365 E5 or standalone Defender licensing for the in-scope workloads, and Global Administrator consent to onboard Azure Lighthouse delegation. A named customer security contact must be available for escalation approvals.

Limitations

This service does not cover on-premises SIEM platforms other than Sentinel, OT and ICS network monitoring, or physical security. Legal e-discovery, forensic imaging, and breach notification are handled by referral to specialist counsel and are not in scope. Response actions that stop production services require named customer approval and are not taken autonomously.
