Azure Sentinel Managed Service — 24/7 SIEM Operations
Deploying Microsoft Sentinel is easy — operating it effectively is not. Without expert tuning, Sentinel generates thousands of alerts daily, most false positives, while genuine threats hide in the noise. Opsio's Azure Sentinel managed service provides 24/7 SIEM operations: custom analytics rules, threat hunting, incident investigation, and continuous tuning that transforms Sentinel from an expensive log collector into an active threat detection platform.

What's Included
Data Connector Management
Configuration and monitoring of Sentinel data connectors for Azure AD, Microsoft 365, Defender for Endpoint, firewalls (Palo Alto, Fortinet, Check Point), cloud platforms (AWS, GCP), and custom sources via CEF/Syslog. Data quality validation ensures complete visibility.
Analytics Rule Engineering
Custom detection rules mapped to MITRE ATT&CK techniques — scheduled queries, fusion rules, ML-based anomaly detection, and near-real-time (NRT) rules. Each rule tuned for your environment to maximise true positive rates while minimising alert fatigue.
SOAR Playbook Automation
Automated incident response workflows using Sentinel SOAR (Logic Apps): automatic enrichment with threat intelligence, user and IP reputation checks, automated containment actions, notification routing, and ticket creation in ServiceNow or Jira.
24/7 Threat Investigation
Every Sentinel alert triaged within 15 minutes by certified SOC analysts. Confirmed incidents receive full investigation with attack chain reconstruction, affected asset identification, and remediation guidance. Threat hunting using KQL queries and behavioral analysis.
Cost Optimisation
Log Analytics workspace cost management through data tiering (Basic Logs vs Analytics Logs), retention policy optimisation, table-level ingestion configuration, and commitment tier recommendations. Reduce Sentinel costs by 30-50% without sacrificing detection capability.
Opsio's focus on security in the architecture setup is crucial for us. By blending innovation, agility, and a stable managed cloud service, they provided us with the foundation we needed to further develop our business. We are grateful for our IT partner, Opsio.

It's simply part of being an Opsio managed-cloud customer.
Transform Sentinel Into Your Active Threat Detection Platform
Microsoft Sentinel collects data from hundreds of sources — Azure AD, Microsoft 365, firewalls, endpoints, cloud workloads — and applies analytics rules to detect threats. In theory, this sounds powerful. In practice, most organisations struggle with Sentinel because they lack the security engineering expertise to tune analytics rules, the 24/7 analyst coverage to investigate alerts, and the threat hunting capability to find advanced threats that rules alone cannot detect. The result is a SIEM that generates noise without delivering security outcomes. Opsio's managed Sentinel service bridges the gap between technology and security outcomes. Our security engineers configure data connectors across your entire environment, build custom analytics rules mapped to MITRE ATT&CK techniques, develop automated SOAR playbooks for common incident types, and tune detection logic to reduce false positives by up to 90%. Our 24/7 SOC analysts investigate every alert, escalate confirmed threats, and perform proactive threat hunting using KQL queries and behavioral analysis.
The managed service includes continuous Sentinel optimisation: adding new data sources as your environment evolves, updating analytics rules for emerging threats, refining SOAR playbooks based on incident patterns, and managing Log Analytics workspace costs through data tiering and retention policies. Monthly security reports provide executive visibility into threat landscape, detection coverage, and incident trends — demonstrating the value of your Sentinel investment to business stakeholders.
