Adaptive Threat Detection

You have the tools.
We connect them.

Managed XDR correlates signals from all your security sources into one integrated picture. One team, one view, coordinated response across every layer.

What is Managed XDR?

Traditional detection looks in silos: endpoint separate, network separate, cloud separate. Managed Extended Detection and Response (XDR) correlates signals from all your security sources into an integrated picture. A suspicious login in the cloud combined with unusual network traffic and a new process on an endpoint tells a story that individual tools cannot narrate. DEFION integrates all data sources under one team that sees the whole chain and responds across every layer simultaneously.

The Service

One view across every security layer

Managed XDR integrates endpoint, network, identity, cloud and email data into one platform with one team that oversees the whole. The correlation engine identifies attack chains that are invisible in individual sources.

Response is equally integrated. When a threat is validated, the team can act directly across all layers: isolate the endpoint, block the user account, adjust the network rule and remove malicious emails, all coordinated in a single response workflow.

You retain full control over the response level. From advisory only to fully automated response: the team calibrates the response mandate to your organisation, your risk appetite and your operational procedures. No surprises, no unilateral action.

The Problem

When tools do not talk to each other

Most organisations have invested in multiple security tools. But when those tools operate in silos, attackers exploit the gaps between them.

  • An EDR alert, a firewall log and a cloud activity event each look harmless in isolation. Only by correlating them across sources does the attack chain become visible.
  • Siloed response slows everything down. By the time alerts from three different tools are manually correlated, the attacker has moved laterally and escalated privileges.
  • Security teams spend more time context-switching between dashboards than investigating threats. XDR puts it all in one place so analysts can focus on decisions, not data aggregation.

For Whom

Which organisations benefit from Managed XDR?

Managed XDR is especially valuable for organisations that have already invested in security tools but struggle to get a unified view and coordinated response.

  • Organisations with multiple security tools operating in silos
  • Companies that struggle to integrate endpoint, network and cloud detection
  • Organisations that want faster, coordinated response to incidents
  • Businesses with hybrid environments: on-premise combined with cloud
  • IT teams spending more time aggregating data than investigating threats

Managed XDR is the natural evolution for organisations that have outgrown standalone SIEM monitoring. It delivers what SIEM promised: unified visibility with the team and response capability to act on it.

Frequently Asked Questions

FAQ

What is the difference between XDR and a SIEM?
A SIEM collects and correlates logs. XDR integrates detection and response across all security layers with native integrations. It is not just about correlation but also coordinated action. XDR is the next step beyond SIEM: it connects endpoint, network, identity, cloud and email data in one unified view.
Do I need to replace my existing tools?
No. Managed XDR integrates with your existing tools. It adds cross-source correlation and coordinated response on top of what you already have. The team advises where potential gaps exist in your current stack.
How far does automated response go?
You decide. From fully manual (advise only) to extensive automated response (immediate isolation on validated threat). The team calibrates the response level to your organisation and risk appetite.
Can Managed XDR also integrate OT data sources?
Yes. OT monitoring can be integrated as a data source into the XDR platform. This provides an integrated view of both IT and OT threats, with cross-layer correlation that individual tools cannot provide.
How fast is response during an incident?
For critical validated threats, initial response is under 15 minutes. Because of the integrated approach, the team can act across multiple layers in a single coordinated action, significantly reducing total response time compared to siloed tools.
