Introduction
Cybersecurity is now a matter of business survival and national resilience! “Highly significant” cyber-attacks rose by 50% in the past year, and the security services in the United Kingdom are now dealing with a new nationally significant attack more than every other day, figures from the National Cyber Security Centre (NCSC) have revealed.
Organisations are adopting hybrid work and cloud systems, which expands the attack surface, and legacy tools can’t keep up. That’s why XDR has emerged as the next-generation solution, evolving from EDR to unify visibility across endpoints, networks, and cloud environments.
For the businesses in the United Kingdom, XDR offers proactive protection through AI, automation, and 24/7 threat intelligence — exactly what Fortray delivers through its MDR/XDR and SOC solutions!
Understanding the Evolution — From EDR to XDR
What is EDR (Endpoint Detection and Response)?
EDR focuses on monitoring, detecting, and responding to threats at the endpoint level (laptops, servers, mobile devices). It uses behavioural analytics and machine learning to identify anomalies and respond automatically to attacks.
However, its limitation is that EDR only sees what happens at the endpoint, not the entire network, email, or cloud environment!
The Next Step — XDR (Extended Detection and Response)
XDR expands beyond endpoints to offer unified detection and response across multiple layers: endpoints, servers, cloud, network, email, and applications.
It collects data from diverse sources, correlates threats in real time, and provides a single, actionable view for IT teams or managed SOCs.
In simple terms: EDR sees one room; XDR monitors the entire building!
The Key Difference Between EDR and XDR
| Feature | EDR | XDR |
| Visibility | Endpoint-only | End-to-End (Endpoint, Cloud, Email, Network) |
| Automation | Limited | Advanced AI-Driven Automation |
| Data Sources | Endpoint Logs | Multi-Source Correlation (SIEM + Threat Intelligence) |
| Response Time | Reactive | Predictive and Proactive |
| Integration | Standalone | Unified Under One Console |

How XDR Works — Simplified Breakdown
Step 1 — Data Collection and Normalisation
XDR gathers data from endpoints, servers, network devices, and cloud apps. It then standardises this information into a common structure for correlation.
Step 2 — AI and Behavioural Analytics
Machine learning algorithms analyse user and device behaviour to identify suspicious patterns or anomalies that may indicate attacks.
Step 3 — Threat Correlation Across Ecosystems
Unlike EDR, XDR cross-checks signals across sources. For example, an email phishing attempt detected in Outlook can be linked to a lateral movement detected on the network.
Step 4 — Automated Response and Remediation
Once a threat is confirmed, XDR isolates endpoints, blocks malicious IP addresses, and triggers alerts —all in real-time.
Managed Detection and Response (MDR) integrates this automation with 24/7 SOC monitoring, ensuring incidents are resolved before they escalate.
Why XDR is the Future of Cybersecurity?
1. Unified Threat Visibility
XDR consolidates all data streams into one dashboard. Clients can monitor endpoint activity, email security, and network traffic from a single pane of glass, improving response speed by up to 50%.
2. AI-Driven Threat Detection
XDR uses machine learning and advanced analytics to detect zero-day exploits and advanced persistent threats (APTs) that bypass traditional tools. Fortray integrates AI-based threat models into its SOC-as-a-Service offering to predict and prevent attacks before they impact critical systems.
3. Reduced Alert Fatigue
Traditional security tools overwhelm IT teams with false positives. The correlation engine of XDR filters redundant alerts, enabling analysts to focus on genuine incidents and reducing noise by up to 80%.
4. Faster Incident Response
By automating threat investigation and response workflows, XDR cuts mean-time-to-detection (MTTD) and mean-time-to-response (MTTR). MDR platform automatically contains threats, isolates infected systems, and initiates recovery procedures.
5. Cloud and Hybrid Security Coverage
With more businesses moving to Microsoft 365, Azure, and AWS, XDR protects workloads across hybrid environments — unifying endpoint, cloud, and network defence.
The Role of XDR in SOC-as-a-Service
XDR as the Intelligence Core of Modern SOCs
Modern Security Operations Centres rely on XDR as their central analytics engine. It integrates SIEM (Security Information and Event Management), EDR, and SOAR (Security Orchestration, Automation, and Response) tools into a single framework.
SOC-as-a-Service — Powered by XDR
SOC-as-a-Service by Fortray leverages XDR technology for:
- 24/7 threat monitoring and triage
- AI-driven alert correlation
- Automated containment and remediation
- Continuous compliance with ISO 27001 and Cyber Essentials Plus
This approach allows businesses to enjoy enterprise-level protection without the overhead of building in-house security teams!
Real-World Example — How XDR Prevented a Ransomware Attack
One mid-sized law firm in London experienced abnormal outbound network traffic after an employee downloaded a malicious attachment!
EDR alone would have quarantined the endpoint — but missed the lateral movement. XDR, through the MDR platform, correlated data between the user’s endpoint, firewall, and email logs, revealing a coordinated attack.
Outcome:
- Threat isolated within 30 seconds
- No data loss
- Forensic report shared with compliance officers
This is how XDR transforms reaction into prevention!
Kevin Mitnick, IT security expert, once said, “The weakest link in cybersecurity is the human being, and the greatest risk when it comes to cyber security is ignorance.”
It takes several years to build trust, and just a few seconds to destroy it. So, staying proactive, and ever ready is a key to success!
