What is managed SIEM?
A managed SIEM (Security Information and Event Management) service combines advanced security technology with expert human analysis to deliver continuous monitoring, threat detection, and rapid incident response. CloudTech24’s security operations team manages every aspect of your SIEM platform, with full oversight 24/7/365.
Our SIEM service captures, analyses, correlates, and enriches security data from servers, endpoints, network devices, applications, and cloud environments. Log collection and retention is aligned with regulatory and compliance requirements, with every log source validated for accuracy. Live threat intelligence is used to provide additional context and to improve detection of malicious activity.
Traditional SIEM deployments often result in a high number of alerts that require extensive tuning and constant review. Without dedicated management, this can lead to alert fatigue and slower responses to genuine threats. With CloudTech24’s Managed SIEM service, our security analysts constantly monitor, triage and prioritise alerts, so we can take swift and effective action. You benefit from our expertise, without the complexity or costs of running an in-house SIEM operation.

The benefits of a managed SIEM service are that it provides constant network monitoring, resulting in faster incident response and threat remediation.
How is data collected by a managed SIEM service?
Agents or connectors are used to collect data from a variety of sources within an organisation’s network. Agents are small software programs that are installed on endpoint devices or servers. They are responsible for collecting data and sending it to the managed SIEM system.
What type of data is collected?
A managed SIEM service collects and analyses system and security logs from servers, endpoints, firewalls, routers, cloud platforms, and applications. It also gathers authentication logs, user activity, email traffic, and threat intelligence feeds.

How is data analysed by a managed SIEM service?
Data is analysed using a combination of automated and manual processes. Automated processes include algorithms and rules that are used to identify patterns and anomalies in the data that may indicate a security threat.
