What is Managed SIEM?

Managed SIEM (Security Information and Event Management) is an outsourced cybersecurity service that monitors your environment 24/7, correlates signals to detect threats, and helps you respond quickly, without building a SOC in-house.

Instead of drowning in alerts, you get decision-ready insights and guided investigations. Automation plus expert analysts = less noise, faster response, and clearer reporting.

Why it matters:
SIEMs typically don’t generate new alerts; they bring data together from identity, endpoint, cloud and network, so you can spot patterns, investigate confidently and act fast.

You gain:

  • Real-time visibility across endpoints, cloud and networks.
  • Automated workflows for faster response
  • Structured incident handling aligned to your processes.
  • Detection of insider threats, cloud misconfigurations, and advanced attacks.

Managed SIEM FAQs

We’ve compiled a list of frequently asked questions and answers to help deepen your understanding of Managed SIEM. 

What is Managed SIEM?

Managed SIEM (Security Information and Event Management) is an outsourced cybersecurity service that collects and analyses log data from across your IT environment to detect suspicious or malicious activity in real time. It flags threats such as unusual login attempts or abnormal user behaviour, helping organisations respond swiftly and effectively.

Traditionally, running a SIEM in-house requires significant investment in staff, infrastructure and expertise.  A Managed SIEM service removes this burden by outsourcing deployment, monitoring, and threat detection to a dedicated 24/7 Security Operations Centre (SOC). This allows your internal team to focus on strategic priorities while maintaining robust, round-the-clock protection.

Our managed SIEM service combines advanced SIEM technology with expert security analysts who proactively monitor, investigate, and respond to threats 24/7. The SIEM platform collects and correlates data from your systems, applications, and network, while our analysts respond to security incidents in real time using enriched alerts and guided response actions.

This man-and-machine approach ensures actionable insights, not alert fatigue, delivering continuous protection, rapid response, and measurable improvements in your security posture.

A traditional SIEM platform is powerful but resource intensive. It requires in-house teams to deploy, configure, and maintain the system. Managed SIEM, on the other hand, provides all the benefits of SIEM technology without the operational overhead. Our SOC handles everything from monitoring and alerting to incident response, ensuring consistent coverage and expert oversight.

Most customers achieve meaningful coverage within weeks, thanks to our standardised onboarding process and pre-built content. Timelines may vary depending on the scope of your environment and access requirements.

Cyberseer’s Managed SIEM pricing is transparent and scalable. We offer a per-user, per-month model, starting from £4.17 per user/month, which includes all necessary infrastructure, software, and 24/7 monitoring. There are no hidden fees – just predictable costs tailored to your environment and data volume. Contact us for a detailed quote.

Yes. We support compliance-aligned reporting across multiple platforms:

  • Exabeam: Out-of-the-box packs for PCI, HIPAA, GPG13, SOX.
  • Google Security Operations/Sentinel: Custom dashboards and evidence trails aligned to compliance frameworks. 

Absolutely. We offer flexible engagement models – fully managed or co-managed. You can choose to co-manage rules, runbooks and consoles with our team, ensuring alignment with your internal processes and visibility.

Our proprietary ASPECT platform enriches and standardises alerts with threat intelligence and contextual data. This enables our analysts to triage effectively and guide your response, ensuring that only high-fidelity, actionable alerts are escalated.

Our Managed SIEM provides broad log source coverage across identity, endpoint, network, cloud and application layers. Supported sources include:

  • Endpoints & servers: Windows, Linux, macOS
  • Network devices: Firewalls, switches, routers, IDS/IPS
  • Cloud platforms: AWS, Azure, Google Cloud, Microsoft 365
  • Applications & databases: Custom apps, SaaS platforms, databases
  • Security tools: Antivirus, EDR, WAF, and other security solutions
  • Identity systems: Active Directory, IAM services, single sign-on platforms

This comprehensive coverage ensures real-time threat detection and complete visibility across your entire IT estate.

The retention period for logs in Cyberseer’s Managed SIEM service is flexible and tailored to your organisation’s compliance and operational needs. Retention periods depend on the platform and service package. Retention periods can be configured to meet specific regulatory requirements or internal policies, ensuring your organisation maintains the necessary audit trails and forensic capabilities.
