Expert-managed Microsoft Sentinel SIEM service for your Microsoft 365 and Azure environments. We deploy, tune, monitor, and operate Sentinel 24/7, so you get world-class threat detection without hiring Sentinel specialists or drowning in alert noise.
Trusted by organizations across the EU and UK | Microsoft Sentinel Certified Specialists | Average cost reduction: 30-40% through optimized data ingestion
From Deployment to Detection Expertise
Sentinel costs spiral without proper management.
The common refrain: “We deployed Sentinel but our team doesn’t have time to tune it. The alerts are overwhelming!” That’s where we come in.

End-to-End Management, Not Just Monitoring
Architecture, RBAC, workspace config, initial connectors, baseline rules, and cost planning.
M365 Defender, Entra ID, Azure logs, collect only high-value telemetry to cut cost & noise.
KQL tuned to your environment and threat model; continuous false-positive reduction.
Logic Apps for isolation, account blocks, session revocation, targeted notifications.
SOC investigations, context-rich escalations, tuning in flight to keep signals meaningful.
Ingestion governance, tiered retention, query optimisation, monthly reporting & roadmap.
Our managed service integrates with full MDR capabilities, Azure security monitoring, and your M365 security baseline.
The Falconer Optimization Framework
We start by enabling the highest-value Microsoft connectors: Microsoft 365 Defender, Entra ID (Azure AD), Defender for Cloud, and key Azure platform logs, mapped to your tenant and use cases. We collect the signals that matter and suppress the ones that don’t, reducing ingestion cost and noise from day one.
Out-of-the-box analytics are a baseline. We tune rules to your naming conventions, Conditional Access policies, identity risks, and typical user/device behaviour. That cuts false positives and surfaces the real incidents, attacks that need immediate action.
We optimize your KQL to run efficiently at scale: indexing, summarizing, and using time-bounded queries to improve performance and reduce cost. The result: faster triage, lower compute, and investigations that won’t stall when volume spikes.
We build Logic Apps playbooks to automate critical containment: device isolation, session revocation, sign-in block, mailbox quarantine, and targeted stakeholder notifications. Automation handles the seconds; analysts handle the judgement.
We enrich detections with Microsoft threat intelligence and curated external feeds. ATT&CK-mapped analytics target identity abuse, BEC patterns in Exchange Online, and Azure misconfigurations. This keeps detections current as attacker tradecraft shifts.
We deliver clear visibility with Sentinel workbooks and monthly reports: detections, response actions, and cost insights, plus a security improvement roadmap. You see risk going down and why.
Our Sentinel-powered MDR integrates seamlessly with Microsoft 365 security optimization for comprehensive protection.

The Path from Deployment to Continuous Defense
Starting from scratch with a comprehensive security foundation
Security assessment, workspace design, and data connector planning. We understand your environment, threat model, and compliance requirements before deploying anything.
Sentinel deployment, data connector configuration, and baseline detection rules. We establish the foundation using Microsoft best practices and our deployment experience.
Detection tuning, playbook development, and alert validation. We optimize specifically for your environment, reducing false positives before you see them.
24/7 monitoring begins. Continuous optimization as your environment evolves and new threats emerge.
Optimizing and enhancing your current Sentinel deployment
Comprehensive review of your existing Sentinel configuration, data connectors, detection rules, and incident response workflows. We identify optimization opportunities and security gaps.
Fine-tune existing detections, optimize data ingestion costs, enhance analytics rules, and implement missing data connectors. We reduce false positives and improve detection accuracy.
Deploy automated response playbooks, integrate with existing tools, and establish escalation procedures. Your team maintains visibility while we handle the heavy lifting.
Seamless transition to 24/7 monitoring with knowledge transfer and documentation. Your optimized Sentinel environment now benefits from continuous expert oversight.
Start with managed Sentinel for SIEM platform management and monitoring. Upgrade to full MDR when you need active threat hunting, incident response, and hands-on threat containment. Many clients follow this natural progression as security maturity grows.
Fixed monthly cost based on data ingestion volume. Clear SLAs for alert response. Dedicated Sentinel architect assigned to your account. No surprises.
This service integrates with full MDR capabilities, starts with a Microsoft 365 Security Assessment, and connects to our broader Microsoft Security Operations.
Frequently Asked Questions
Yes. We provide Sentinel health checks, optimization, and takeover services for existing deployments. We audit your configuration, tune detection rules to reduce alert noise, optimize data ingestion to lower costs, fix misconfigurations, and transition to 24/7 managed monitoring. Most takeover projects complete within 3-4 weeks.
Managed Sentinel focuses on SIEM platform management: deployment, tuning, monitoring, and alert triage. MDR (Managed Detection & Response) adds proactive threat hunting, hands-on incident response, and active threat containment across your entire Microsoft environment. Many clients start with managed Sentinel and upgrade to full MDR as security needs increase.
