Advanced security monitoring with
Microsoft Sentinel SIEM.
For businesses that need visibility beyond endpoints and email, CIO Tech deploys Microsoft Sentinel as a cloud-native SIEM (Security Information and Event Management) platform. Logs from across your environment are collected, correlated, and analysed. Our managed SOC team monitors the output and responds to confirmed threats.
One place to see everything that matters
SIEM stands for Security Information and Event Management. It collects logs from your endpoints, servers, email, cloud services, firewalls, and identity systems. Then it correlates those logs to detect patterns that no single tool can see on its own. A failed login on its own is noise. A failed login followed by a successful login from a different country followed by a mailbox rule change is an attack.
Centralised log collection
Logs from Microsoft 365, Azure AD, endpoints, servers, firewalls, and cloud applications. All collected in one platform. No more checking five different dashboards to understand what happened.
Event correlation
Sentinel uses analytics rules to connect events across different sources. It spots multi-stage attacks that happen across email, identity, and endpoints. Individual events that look harmless are correlated into incidents that reveal the full attack chain.
Threat intelligence feeds
Sentinel ingests threat intelligence feeds that identify known malicious IP addresses, domains, and file hashes. If any of your systems communicate with a known bad actor, the alert fires before damage is done.
Managed SOC team
SIEM generates the data. Humans make the decisions. CIO Tech’s security operations team monitors Sentinel, triages incidents, hunts for threats that automated rules might miss, and responds when action is needed. You do not need to hire a security analyst.
Cloud-native SIEM that scales without hardware
Traditional SIEM platforms require dedicated servers, complex tuning, and a full-time security team to manage them. Microsoft Sentinel runs in the cloud, integrates natively with Microsoft 365 and Azure, and scales automatically. For businesses already running M365, it is the natural fit.
No hardware required
Sentinel runs entirely in Azure. No on-premises servers to maintain. No storage to manage. No capacity planning. It scales automatically based on the volume of data your environment generates.
Native M365 integration
Sentinel connects to Microsoft 365, Azure AD, Defender, and Intune with built-in connectors. Log data flows in automatically. No complex integration work. The data that matters most for Australian SMBs is already there.
Built-in detection rules
Hundreds of pre-built analytics rules and workbooks from Microsoft and the security community. CIO Tech tunes these for your environment and adds custom rules based on the threats most relevant to Australian businesses.
Automated response playbooks
Sentinel supports automated playbooks that trigger actions when specific conditions are met. Block an IP address, disable a compromised account, or send an alert to the CIO Tech team. The first response happens in seconds, not hours.
Not every business needs SIEM. Here is who does.
CIO Tech’s standard Security Stack and 24/7 threat detection cover most small and mid-size businesses. SIEM adds a deeper layer for organisations with specific requirements.
SIEM makes sense when you:
- Handle sensitive data (financial, medical, legal) and face regulatory obligations
- Need centralised logging for audit or compliance requirements
- Have a complex environment with multiple cloud services and on-premises systems
- Your cyber insurer requires log retention and security event monitoring
- Want to move towards Essential Eight Maturity Level 2 or 3
The standard stack may be enough if you:
- Have fewer than 50 users and a straightforward environment
- Run primarily on Microsoft 365 without complex on-premises infrastructure
- Do not have regulatory requirements for centralised log retention
