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.

Why choose CloudTech24's managed SIEM services?

There are a number of benefits to partnering with CloudTech24 for your managed SIEM services:

  • We deliver enterprise-grade detection, monitoring, and response
  • Ideal for organisations without a dedicated security teams – you avoid the cost and complexity of managing SIEM internally.

Managed SIEM - FAQs

We often receive questions about our Managed SIEM, so we thought we would clear them up with some helpful FAQs. Alternatively, if you’d like to pick the phone up and speak with us, we would be more than happy to help.

SIEM stands for Security Information Event Management.

A managed SIEM tool works by collating data from multiple sources, giving you visibility of data from a central location. It can be configured to enrich results, such as flagging malicious activity based on inputs and incorporating cyber intelligence from third party sources.

The benefits of a managed SIEM service are that it provides constant network monitoring, resulting in faster incident response and threat remediation.

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.

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. By collating this data, the SIEM provides a central view of your network’s security posture and helps identify unusual or suspicious behaviour that may indicate a threat.

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.

A managed SIEM service can detect a wide range of security threats, including:

  • Network intrusions
  • Unauthorised access to sensitive data
  • Insider threats
  • Denial of service attacks

CrowdStrike Falcon Next-Gen SIEM is a market-leading SIEM platform. When used in conjunction with other CrowdStrike solutions it provides a unified platform for data analysis, with advanced visibility across endpoints, cloud, and networks.

22/04/2026

Working with CloudTech24 has been a genuinely smooth and valuable experience from start to finish. The onboarding process was structured and efficient, with the team taking time to fully understand our setup, risks, and goals before implementing any solutions.

Day-to-day, their support has been consistently reliable. Issues are handled quickly, often before they become real problems, and there’s a clear proactive approach rather than just reactive fixes.

Their cybersecurity expertise has also added a strong layer of confidence, we know our systems, data, and users are properly protected.

What stands out most is the level of service. Communication is clear, response times are fast, and nothing feels like too much trouble. They operate more like an extension of our team than an external provider, which makes a big difference.

Overall, it’s taken a lot of stress away from managing IT internally and allowed us to focus on growing the business, knowing everything behind the scenes is in safe hands.

CloudTech24 have been a huge support to Positively Adam, providing reliable IT and cybersecurity services here in London.

From day one, their approach has been proactive rather than reactive. Their 24/7 support gives real peace of mind, issues are handled quickly, communication is clear, and nothing feels left hanging. It’s reassuring to know our systems are constantly monitored and protected.

They’ve strengthened our Microsoft 365 setup, tightened our security, and made our overall IT infrastructure far more streamlined and resilient. Most importantly, they explain everything in straightforward terms, which makes decision-making easy and stress-free.

If you’re looking for an IT partner that genuinely adds value and helps your business run smoothly, I highly recommend CloudTech24.

We’ve been working with CloudTech24 for our IT support and cybersecurity in London, and the service has been outstanding.

Their 24/7 support genuinely makes a difference. Any issues are picked up quickly, resolved efficiently, and communicated clearly, no chasing, no confusion. You can tell they proactively monitor systems rather than just reacting when something breaks.

What really stands out is their professionalism and technical expertise. From Microsoft 365 support to strengthening our overall cybersecurity posture, everything feels structured, secure, and well-managed. They explain technical matters in plain English, which is invaluable for non-technical teams.

If you’re a London-based business looking for reliable, proactive IT support that actually feels like a partnership rather than a helpdesk, I wouldn’t hesitate to recommend CloudTech24.
