What is SIEM?
Security Information and Event Management is a set of integrated log management and monitoring tools that help organisations detect targeted attacks and data breaches. SIEM systems aggregate and analyse log event information from devices, infrastructure, systems and applications to detect suspicious activity inside networks. When anomalous behaviour is identified, an alert is generated for investigation.
How can a managed SIEM service from Redscan help?
Organisations that invest in SIEM can quickly realise that they are unable manage it without a large team of security experts to deploy their chosen solution and analyse and respond to the high volume of alerts it is likely to generate. Alert fatigue is a common problem for security teams, often leading to important alerts being missed or overlooked. A high proportion of SIEM alerts are also false positives.
For an affordable subscription, Redscan provides the people, technology and intelligence your organisation needs to get the most out of SIEM. Certified to deploy and manage a range of SIEM solutions, our Security Operations Centre (SOC) professionals work as an extension of your in-house team to enhance threat detection and response capabilities and alleviate the burden of analysing and investigating security alerts 24/7.

- What is SIEM and how does it work?
Security Information and Event Management technologies integrate with a wide range of event log and threat intelligence sources to help organisations identify and respond to security incidents.
SIEM combines the event monitoring, correlation and notification capabilities of security event management (SEM) with the analysis, retention and reporting functions of security information management (SIM).
SIEM solutions work by aggregating and analysing log data from devices, infrastructure, systems and applications and generating alerts for security teams to review and respond to.
- What is SIEM used for?
SIEM is used by organisations to improve visibility of cyber security threats inside a network. SIEM solutions can help to achieve the cyber security monitoring capabilities needed to support compliance with the GDPR, NIS Directive, PCI DSS, as well as other data regulations and standards.
- What is the best SIEM solution for your business’s needs?
With so many SIEM solutions available, it can be difficult to know which one to choose. Some technology vendors incorporate SIEM as part of broader threat management platforms.
Rather than focusing purely on price or reputation, buyers should consider how well a SIEM solution will integrate with existing data sources to provide the threat coverage and visibility needed to address SIEM use cases. Deployment options, support for threat intelligence sources and incident response capabilities are also important considerations.
- What tools does SIEM integrate with?
To facilitate event correlation and alerting, SIEM tools collect logs from a wide range of data sources. Sources typically include network devices, infrastructure, systems, applications and security technologies such as firewalls, endpoint protection platforms and intrusion detection and prevention systems. To enhance threat visibility and coverage, some SIEM tools can also be integrated with Endpoint Detection and Response (EDR) tools.
- How much does a SIEM cost?
A shift in the SIEM market, largely driven by cloud, has seen vendors’ delivery models change from perpetual to fixed term licencing. The price of a SIEM tool can be dependent on factors such as volume of log events, number of employees, and storage requirements.
- What are the main SIEM challenges?
If not deployed and maintained properly, SIEM solutions can generate a sizeable volume of alerts. Organisations without a large, dedicated security team often struggle with the time-consuming task of trawling through SIEM alerts to identify genuine security incidents. Even when genuine threats are identified, knowing how to quickly and effectively respond them is a separate challenge in itself.
A managed SIEM service helps organisations to bridge the resource gap by providing the latest SIEM technology as well as the security professionals needed to manage and monitor it, 24/7.
