Why Organisations Choose Our Managed SIEM Service
Eliminate Alert Fatigue
Tired of your security team drowning in SIEM alerts? Our analysts filter thousands of events daily, investigating potential threats and only escalating genuine security incidents that require action. We’ve helped clients reduce their daily alert volume from hundreds to a manageable handful of real threats.
Maximise Your SIEM Investment
Many organisations invest £50k+ in SIEM technology only to use 20% of its capabilities due to lack of expertise. Our team ensures you’re getting full value from your investment through expert tuning, custom use case development and continuous optimisation.
Access Specialist Expertise Without the Hire
Hiring and retaining skilled SIEM analysts is expensive and challenging. The average SIEM analyst salary in the UK is £50k-£70k, plus training costs and the risk of staff turnover. Our managed service gives you access to a team of specialists for a fraction of that cost.
Accelerate Time to Value
New SIEM deployments typically take 6-12 months to reach optimal performance. With our experts handling configuration, tuning and optimisation from day one, you’ll see actionable security intelligence within weeks, not months.
