Managed Extended Detection & Response (XDR) Service
Cyber-attacks continue to increase in frequency and sophistication, causing greater risk, uncertainty and harm to organisations in every industry around the world. Businesses are operating larger and ever-more complex IT environments that require a broader set of skills, deeper knowledge and yet more funding to defend themselves than ever before. At the same time, cyber skills remain in short supply worldwide, making the competition for talent fiercer than ever.
Quorum Cyber’s new flagship Managed XDR service provides comprehensive security across your whole IT estate, freeing your teams to concentrate on your core business. Our solution focuses on business results and outcomes while reducing the total cost of ownership (TCO) to give you a clear return on investment (ROI) – regardless of the size, complexity and geographical footprint of your business.
Our Managed XDR (Extended Detection & Response) combines the strengths of Microsoft’s two families of Defenders into one single service: Managed XDR = Microsoft 365 Defender + Microsoft Defender for Cloud + Microsoft Sentinel.
Employing the all-seeing Microsoft Sentinel in our XDR service, we monitor absolutely everything, from any vendor, in your IT ecosystem, be it on-premises or in the cloud, in Operational Technology (OT) or the Internet of Things (IoT). We scan laptops, smartphones and other devices through to email, networks, identities, virtual machines, databases and firewalls, and any type of operating system and any cloud environment, including from Amazon Web Services (AWS), the Google Cloud Platform (GCP) and Microsoft Azure.
Our premium service includes our Microsoft Sentinel Managed Detection & Response (MDR) as standard to give you complete peace of mind every day of the year.

Superior features of Managed XDR
The ‘Managed’ component of our Managed XDR service means that our experienced threat hunters will proactively monitor your environment on a daily, weekly and monthly basis, ensuring you have the best security protection possible as Microsoft continues to update features and products. Our threat experts will investigate any suspicious activity that’s flagged by our automated threat monitoring technology. This approach makes the most of human intelligence and creativity combined with time-saving software. We’ll help you streamline your portfolio of products and licences to ultimately adopt a single security ecosystem to take full advantage of Microsoft’s $1 billion per year investment in cyber security.

Why Quorum Cyber is a Microsoft-only cyber security house
Years prior to starting Quorum Cyber as a business, we predicted that the cyber security market was going to grow enormously. And we foresaw that three large technology companies would invest in expanding their services to push aside incumbent specialist vendors. From the outset, our strategy was to partner with Microsoft, whom we were confident would eventually become the dominant company in the market.
Since then, our partnership has allowed us to invest in talented people and Microsoft Security technologies to provide the best possible skills and services to our customers around the world. Our team of deeply-qualified, highly-experienced professionals sets us apart from the competition.

Microsoft XDR FAQs
We answer our customers’ most commonly asked questions and give guidance on the security benefits that Microsoft XDR 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 environments, endpoints, identities, networks, email and containers, virtual machines, Operational Technology (OT) and the Internet of Things (IoT) 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 (SOC) teams need a platform that intelligently brings together all relevant security data and reveals advanced threats.
How does Managed 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, servers and clouds.
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.
