Quorum Cyber’s Microsoft Defender Managed Service combines the depth and breadth of incident response and threat hunting experience of Quorum Cyber security engineers with Microsoft Defender XDR, the most comprehensive ecosystem of cyber security defensive capabilities, created by Microsoft.

Using our threat hunting team to drive security engineering improvements in Microsoft Defender XDR, we are able to continuously improve your defences and contain cyber security incidents before they are able to achieve their objectives.

As a result, organisations can significantly reduce the probability of an attack, reduce the dwell time of an attacker, and reduce the workload of security teams, keeping the risk exposure of any organisation of any size and industry within their intended risk appetite.

The threat landscape continues to increase in both complexity and the level of sophistication of the attacks we observe. Attackers target the most vulnerable resources in an organisation and then traverse laterally to target high-value assets. No longer can you expect to stay safe by protecting individual areas such as email or endpoints.

Getting to know XDR

Our Microsoft Defender Managed Service is delivered in two tailored experiences, Microsoft 365 Defender for end-user environments and Azure Defender for cloud and hybrid infrastructure.

Extended Detection and Response (XDR) is an emerging service to help security operations; resulting from the growing security skills gap and attacker trends.

Microsoft Defender XDR FAQs

We answer the questions commonly asked by our customers and provide guidance on the security benefits Microsoft Defender can provide your organisation.

What is Extended Detection and Response (XDR)?

XDR is a security threat detection and incident response tool. Providing extended visibility, analysis, automation and response across Multi-Cloud, Hybrid, Endpoints, IoT, Identities, Network, Email, Containers, VMs, and more, while applying analytics and automation to detect, analyse, hunt, and remediate today’s and tomorrow’s threats.

XDR is a more advanced progression of endpoint detection and response (EDR) security.

Security Operations Centre’s (SOCs) need a platform that intelligently brings together all relevant security data and reveals advanced threats.

How does Microsoft Defender XDR work?

Microsoft Defender XDR collects and correlates data against endpoints, servers, email, cloud and networks enabling visibility of advanced threats. These threats can then be analysed and prioritised in order to allow threat hunting and remediation. With this increased visibility and content into active threats, XDR allows security teams to quickly focus on, eliminate, and therefore mitigate, any serious impact to the business. Ultimately, XDR allows teams to reduce the scope and severity of any cyber-attack.

What are the benefits of XDR?

The primary benefits of XDR are:

  • Increased detection, protection and response capabilities
  • Increased productivity of security team and other operational personnel

XDR ingests and distils multiple streams of telemetry and will improve critical SOC functions when they are responding to an attack in their environment.

XDR security provides advanced threat detection and response capabilities, including:

  • Converting a large number of alerts and streamlining them into a more manageable number of incidents. This increases the efficiency of the security team when dealing with these incidents.
  • Provides response options which encompass more than just infrastructure control points, including endpoints and network.
  • Allows for increased automation capabilities.

What are the advantages that XDR has over EDR?

XDR extends the capabilities of EDR across all the security layers in the environment — such as email, networks, server and cloud.

XDR allows security teams to see the ‘entire picture’ by enabling telemetry and behavioural analysis across multiple security layers, as opposed to the single point of view provided by EDR.

XDR provides an overview of activity across the system that avoids any visibility gaps. This enables security teams to better understand where the threat has come from, but also, how the attack is spreading across the security environment.

XDR offers greater analysis and correlation capabilities.
