Only get called when it actually matters.
24/7 monitoring by DEFION analysts. AI filters the noise, humans validate and escalate. Threats are stopped before they cause damage.
What is Managed Threat Detection?
You have a SIEM and EDR. But who watches them day and night? Managed Threat Detection is the managed layer on top of your technology: DEFION analysts monitor your environment 24/7, validate every alert and call you only for a real threat. AI processes the volume, humans deliver the verdict. Detection goes beyond known signatures: behavioural analytics and UEBA identify threats that automated rules miss.
See threats before they cause damage
Managed Threat Detection is at the core of effective cybersecurity: the ability to see threats before they cause damage. The team monitors your environment 24/7 for indicators of compromise, suspicious behaviour and anomalies that point to an active threat.
Detection goes beyond intercepting known signatures. Behavioural analytics, UEBA (User and Entity Behavior Analytics) and advanced correlation rules identify threats that evade signature-based detection. The team knows your environment and understands what normal behaviour looks like, so deviations stand out immediately.
Every alert is validated by a threat analyst. No automatic forwarding of alerts, no alert fatigue. You only receive notifications about validated threats with context, impact assessment and recommended actions. Detection rules are continuously adapted based on the threat landscape, threat intelligence and experiences from your specific environment.
Threats you miss without continuous monitoring
Modern attackers move slowly and carefully through your environment. Without 24/7 monitoring, you miss the signals that together form an attack.
- Your security team cannot monitor all log sources day and night. Attackers strike outside office hours and wait patiently for the right moment.
- Standalone tooling generates hundreds of alerts per day. Without validation you do not know which are urgent and which are noise. Alert fatigue leads to missed incidents.
- The average dwell time of an attacker in a network is weeks to months. The longer a compromise goes unnoticed, the greater the eventual damage.
What is monitored
How DEFION delivers Managed Threat Detection
Onboarding and baseline
Integration of data sources, establishing normal behaviour in your environment. Onboarding typically takes two weeks.
Detection engineering
Configuration of detection rules based on MITRE ATT&CK and your specific threat profile and sector.
24/7 monitoring and AI filtering
AI continuously processes log volume and filters known noise. Suspicious behaviour is flagged for manual validation.
Alert validation and triage
Every alert is assessed for severity, context and impact by a DEFION threat analyst. No false positives forwarded.
Escalation and response
Validated threats are escalated with recommended actions. Direct action is taken for critical incidents.
Continuous optimisation
Monthly tuning of detection rules, threat intelligence updates and addition of new use cases.

Which organisations is this relevant for?
Managed Threat Detection is suitable for any organisation that needs 24/7 detection but cannot or does not want to staff this itself.
- Organisations that need 24/7 monitoring without their own SOC
- Companies with existing security tools that are underutilised
- IT teams experiencing alert fatigue from too many unfiltered notifications
- Organisations with NIS2, ISO 27001 or DORA obligations around monitoring
- Companies that want to structurally increase their security maturity
Relevant triggers: a recent incident, an upcoming NIS2 audit, a growing IT environment without additional security capacity, or a CISO who wants to demonstrate proactive detection to the board.
Vendor-agnostic by design
DEFION works with the tooling you already have, or brings ours. No vendor lock-in.
