Expert Microsoft Sentinel platform management with automated threat detection for organisations with internal security teams. We deploy, configure, and continuously tune your cloud-native SIEM, build custom detection rules, optimise costs by 30%, and reduce false positives by 70% - while your security team handles alert triage and incident response.
Book Security AssessmentMicrosoft Sentinel surfaces thousands of alerts, but without expert correlation and tuning, critical threats drown in noise. Managed expertise ensures your detections align with your environment.
Deploying Sentinel is easy; maintaining its efficiency is not. Log ingestion, cost optimisation, and analytic rule updates require continuous attention to keep detections accurate and affordable.
With optimised rules, Managed Sentinel delivers a clear picture of your security posture. You see prioritised, context-rich alerts that your team can act on - without the noise or confusion of raw telemetry.
Sentinel costs spiral without proper management. Average unmanaged Sentinel deployment monthly costs are very high in data ingestion alone. Our optimised deployments typically run much cheaper monthly. Same visibility, better tuning, 30-40% cost reduction.
"We deployed Sentinel but our team doesn't have time to tune it. The alerts are overwhelming!"
Common refrain from security teams
That's where we come in.
Architecture, RBAC, workspace configuration, initial connectors, baseline rules, and cost planning.
M365 Defender, Entra ID, Azure logs - collect only high-value telemetry to cut cost and noise.
KQL queries tailored to your environment and threat model. New detection rules added as threats evolve.
Logic Apps for isolation, account blocks, session revocation, and targeted notifications.
Continuous optimisation to reduce noise. Your team focuses on real threats, not alert fatigue.
Platform performance metrics showing detection rule efficacy, alert volume trends, and false positive reduction progress.
Our managed service integrates with full MDR capabilities, Azure security monitoring, and your M365 security baseline.
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.
Sentinel's pre-built analytics rules are generic - they generate false positives in every environment. We tune them for YOUR specific environment. A "risky sign-in from new location" means something different for a global sales team versus a single-office accounting firm. Context matters.
We optimise your KQL to run efficiently at scale: indexing, summarising, 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.
| Aspect | DIY Sentinel | Managed Sentinel |
|---|---|---|
| Team Requirements | 2-3 FTEs + continuous training | Fraction of FTE cost, expert management from day one |
| Time to Value | 6-12 months to effectiveness | 2-4 weeks to optimised monitoring |
| Alert Quality | High alert noise / false positives | ~70% noise reduction via tuning |
| Cost Control | Uncontrolled ingestion costs | 30-40% cost reduction |
Average time to hire a qualified Sentinel expert is 6-9 months in the current market. We deploy and optimise your Sentinel platform in 2-4 weeks, ready for your team to monitor with confidence.
Deep integration with Microsoft 365 security monitoring, Azure security and Sentinel, and Defender for Cloud creates comprehensive protection.
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 optimise specifically for your environment, reducing false positives before you see them.
Platform handover to your team for alert monitoring. Ongoing platform optimisation, detection rule tuning, and cost management continues as your environment evolves and new threats emerge.
Start with Managed Sentinel for SIEM platform management: we optimise the platform, your team monitors alerts. Upgrade to full MDR when you need 24/7 SOC analyst monitoring, alert triage, threat hunting, and hands-on incident response. Many clients follow this natural progression as security maturity grows or internal team capacity becomes constrained.
Fixed monthly cost based on data ingestion volume. Clear SLAs for platform optimisation and rule tuning. Dedicated Sentinel architect assigned to your account. No surprises.
4-6 weeks (new deployment) | 3-4 weeks (takeover)
This service integrates with full MDR capabilities, starts with a Microsoft 365 Security Assessment, and connects to our broader Microsoft Security Operations.
A straightforward service model designed around real-world needs.
A Managed Sentinel service means we deploy, configure, tune, and optimize Microsoft Sentinel SIEM for you, providing expert platform management, custom detection rules, automated playbooks, and continuous optimization without requiring you to hire dedicated Sentinel architects or become KQL experts. We handle the platform complexity; your team handles alert monitoring and incident response (or upgrade to MDR for 24/7 SOC coverage).
Sentinel requires expert configuration, custom detection rules, data connector optimization, and continuous alert tuning to be effective. Most organizations lack the specialized Sentinel architecture expertise needed to maximize the platform’s value, resulting in high costs, overwhelming false positives, and missed threats. The deployment is only the starting point. Effective security requires ongoing expert platform management to generate high-fidelity alerts your team can act on confidently.
Yes. We provide Sentinel health checks, optimization, and platform management for existing deployments. We audit your configuration, tune detection rules to reduce alert noise, optimize data ingestion to lower costs, fix misconfigurations, and provide ongoing platform management while your team continues alert monitoring. Most takeover projects complete within 3-4 weeks.
Managed Sentinel is focused on platform management – we deploy, configure, and continuously optimize Microsoft Sentinel to ensure efficient data ingestion, high-fidelity detections, and reliable automation through playbooks and rules.
Your internal team remains responsible for day-to-day alert monitoring and incident response.
MDR (Managed Detection & Response) builds on top of Managed Sentinel. It adds 24/7 SOC operations – our analysts actively monitor alerts, triage incidents, investigate threats, and perform hands-on containment and response (depending on tier).
In short: Managed Sentinel gives you the platform; MDR gives you the team that runs it.
Many organizations begin with Managed Sentinel to establish a tuned and cost-efficient SIEM foundation, then upgrade to MDR once they require around-the-clock threat monitoring or lack in-house SOC capacity.
