Alert fatigue is overwhelming your team.
Too many tools generate too many alerts, burying critical threats in the noise.
Threats are outpacing traditional security tools
Cyber threats in Australia are growing in scale, speed, and sophistication. Yet most organisations are still operating with siloed tools, alert fatigue, and security teams stretched beyond capacity.
The answer is not more tools. It's a unified, intelligent platform that brings your entire digital estate into view and responds at machine speed.
Are these challenges familiar?
Siloed security tools leave blind spots.
On-premises, cloud, endpoints, and Saas tools don’t share signals. Attackers exploit the gaps.
SOC staffing and skills are scarce.
Recruiting and retaining experienced security analysts is expensive and increasingly difficult.
Legacy SIEM costs are spiralling.
Splunk and QRadar licensing, infrastructure, and maintenance costs are unsustainable at scale.
Microsoft Sentinel: The Cloud-Native SIEM built for the AI Era
Give your security team complete visibility with AI-driven threat detection and automated response through Microsoft Sentinel.
Microsoft Sentinel is a cloud-native Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platform. It ingests signals from across your entire digital estate (multi-cloud, on-premises, endpoints, and SaaS) and uses AI to detect, investigate, and respond to threats at scale.
Since 2025, Sentinel has been unified with Microsoft Defender XDR in a single Defender portal, giving security teams a consolidated console for SIEM and XDR capabilities. Microsoft was recognised as a Leader in the 2025 Gartner Magic Quadrant for SIEM.
SIEM + SOAR in one platform
Collect, detect, investigate, and respond to threats – all within a single unified platform, without the cost of managing separate SOAR infrastructure.
AI-driven threat detection
Built-in machine learning and Security Copilot integration surface threats faster than rule-based approaches, with explainable verdicts your team can act on.
Cloud-scale economics
Pay only for what you ingest, with commitment tiers offering up to 32% savings, and the new 50 GB tier making enterprise SIEM accessible for smaller organisations.
Microsoft Sentinel core capabilities
What can Microsoft Sentinel do for your organisation? These core capabilities make Sentinel crucial for defending against emerging threats:
- Comprehensive Threat Detection. Collect and analyse signals from 350+ data sources: firewalls, endpoints, cloud environments, identity platforms, and SaaS apps. Sentinel's codeless connector platform lets you onboard any source, with detection rules, dashboards, playbooks, and hunting queries available out of the box.
- Security Copilot and Agentic AI. Microsoft Security Copilot brings generative AI to incident response, summarising incidents in natural language, suggesting remediation steps, and powering agentic workflows. The Sentinel MCP server connects AI agents to your security data for advanced automation.
- Sentinel Graph. Sentinel graph builds a connected intelligence layer that links users, devices, alerts, behaviours, and incidents. It illuminates hidden attack paths and entity relationships, surfacing risks that traditional alert-based detection misses entirely.
- Sentinel Data Lake. A cloud-scale security data foundation for cost-effective, long-term retention of high-volume telemetry. Supports direct ingestion from Microsoft Defender for Endpoint, Office, and Cloud Apps, without the cost of the full analytics tier, enabling richer historical investigation.
- User and Entity Behaviour Analytics (UEBA). The generally available UEBA behaviours layer aggregates security telemetry into clear, human-readable behavioural summaries. It detects insider threats and compromised accounts by identifying deviations from normal patterns across Microsoft and third-party sources, including AWS, GCP, and Okta.
- SOAR and Automated Incident Response. 200+ customisable playbooks automate routine response tasks, from account isolation to ticket creation, so your analysts focus on complex investigations. Machine learning correlates alerts into prioritised incidents, reducing mean time to respond across your environment.
Microsoft Sentinel in action
Explore common use cases for Microsoft Sentinel that boost security operations and maintain compliance:
- Threat Detection and Incident Response. Gain comprehensive visibility by collecting and correlating data from firewalls, endpoints, cloud environments, and identity platforms. Sentinel helps your team identify and prioritise threats and respond swiftly through automated playbooks.
- Multi-Cloud Security Monitoring. Purpose-built for cloud environments, Sentinel provides native monitoring of Microsoft Azure alongside AWS, GCP, and hybrid infrastructure. New connectors include AWS Network Firewall, GCP Cloud Run, VPC Flow, and Palo Alto Prisma.
- Centralised Log Management and Compliance. Consolidate all security logs, whether on-premises and cloud, into a single hub. Sentinel simplifies compliance, auditing, and long-term retention through its data lake, supporting Australian regulatory frameworks, including the ASD Essential Eight and the Privacy Act.
- Insider Threat Detection. The UEBA behaviours layer analyses cross-platform behaviour patterns across Microsoft Entra ID, AWS, GCP, and Okta, surfacing anomalous access, data exfiltration, and privilege misuse before they escalate.
- SIEM Migration from Splunk or QRadar. Modernise your SOC by migrating from legacy SIEM platforms. Microsoft's AI-assisted SIEM migration experience automates the translation of detection rules and the setup of data connectors. Professional Advantage provides full migration services and post-deployment support.
- Proactive Threat Hunting. Give your analysts cutting-edge tools to actively investigate potential threats. Sentinel's KQL-based hunting queries, combined with Sentinel graph and custom graph visualisations via the VS Code extension, enable deep investigation without writing detection rules from scratch.

A standard Microsoft Sentinel deployment typically takes 4 to 12 weeks, depending on the size of your environment, the number of data sources, and the complexity of your detection and automation requirements.
Professional Advantage follows a structured methodology covering assessment, design, deployment, and handover, with ongoing managed services available post-deployment.
Microsoft Defender XDR is an endpoint-to-cloud detection and response platform focused on Microsoft's own security signals (endpoints, identities, email, cloud apps).
Microsoft Sentinel is a SIEM that ingests logs and signals from any source, including third-party tools like Cisco, AWS, Splunk, and SAP, and applies AI-driven analytics across your entire environment. Since 2025, both platforms have been unified in the Microsoft Defender portal, but they serve distinct, complementary roles. Most enterprise environments benefit from both. Learn more about Microsoft Sentinel in this article.
Yes. Microsoft Sentinel is a full-featured SIEM that can replace legacy platforms like Splunk and QRadar.
Microsoft now provides an AI-assisted SIEM migration experience that automates the migration of detection rules and data connectors, significantly reducing the effort required.
