Extended Detection & Response (XDR)
Most mid-sized companies have security tools. An antivirus here. A firewall there. Maybe an email filter. Each one generates its own alerts, writes its own logs, and watches its own narrow slice of your environment.
The problem is that modern attacks don't stay in one place.
An attacker compromises an employee's email credentials through a phishing link. They use those credentials to log into your cloud environment from an unfamiliar location. They escalate privileges, access a shared drive, and begin exfiltrating client data. Each of those steps, in isolation, might look like a low-priority alert — or no alert at all. Your email filter saw a clicked link. Your identity provider logged a new location. Your cloud platform noticed a file download. None of them flagged it as an attack because none of them could see the full picture.
That's the gap XDR closes.
What XDR actually is
XDR — Extended Detection & Response — is a platform that ingests telemetry from across your entire IT environment and correlates it into unified detections.
Instead of five separate dashboards producing five separate alert queues, XDR takes signals from your endpoints (laptops, servers, mobile devices), your email platform (Microsoft 365, Google Workspace), your cloud infrastructure (Azure, AWS), your identity provider (Entra ID, Okta), and your network — and analyses them together.
When that phishing click is followed by an unusual login, followed by a privilege escalation, followed by a bulk file download — XDR doesn't produce four low-severity alerts. It produces one high-severity incident with the full kill chain mapped out. Our analysts see the entire story in a single pane, and they respond accordingly.
This is not antivirus with a better dashboard. This is a fundamentally different approach to detection — one that mirrors how attackers actually operate.
How an attack plays out without XDR
Monday, 09:14 — An employee in your finance team clicks a link in what appears to be a DocuSign notification. The link redirects through a legitimate domain to a credential harvesting page. They enter their Microsoft 365 password. Your email filter doesn't flag it — the link passed URL reputation checks at delivery time.
Monday, 09:47 — The attacker logs into Microsoft 365 using the stolen credentials from an IP address in Eastern Europe. Your identity provider logs the event but doesn't block it — MFA wasn't enforced for this user group.
Monday, 10:22 — The attacker creates an inbox rule to forward all incoming email to an external address. They begin browsing SharePoint, downloading financial reports, client contracts, and board documents.
Monday, 14:00 — Your IT admin notices "unusual activity" in a weekly log review. By now, 4.7 GB of data has left your environment. The attacker has been inside for nearly five hours.
With XDR: The credential harvesting click, the anomalous login, the inbox rule creation, and the SharePoint access would have been correlated into a single high-severity alert within minutes. Our SOC would have isolated the account, revoked the session, and begun containment before the first file was downloaded.
What's included
Deployment & configuration — We integrate XDR across your endpoints, email, identity, cloud, and network. No rip-and-replace required. We work with your existing Microsoft, Google, or hybrid environment.
Custom detection rules — Out-of-the-box rules catch common threats. We build custom detections tuned to your environment — your industry, your geography, your risk profile.
Correlated alerting — Alerts are deduplicated, enriched with context, and prioritised by severity. Your team doesn't see noise. Our analysts see signal.
24/7 SOC monitoring — Every alert is reviewed by a human analyst. Not a chatbot. Not an auto-closer. A trained security professional who investigates, escalates, and responds.
Monthly threat reports — A clear summary of what we detected, what we blocked, and what changed in your threat landscape. Written for leadership, not just IT.
Ongoing tuning — Detection rules evolve as your environment changes. New applications, new users, new offices — we adjust continuously.
How we deliver it
Week 1–2: Discovery and scoping. We map your environment — every data source, every integration point, every identity provider.
Week 2–4: Deployment. We roll out XDR agents and integrations with zero downtime. Your team keeps working. We handle the technical lift.
Week 4–6: Tuning and baseline. We establish what "normal" looks like in your environment so detections are accurate from day one. False positives get suppressed. Real threats get escalated.
Ongoing: Continuous monitoring, detection refinement, and incident response. Monthly reporting to your leadership team.
FAQ
"We already have Microsoft Defender. Why do we need XDR?" Microsoft Defender is an endpoint protection tool — it watches devices. XDR correlates signals across endpoints, email, identity, cloud, and network simultaneously. Defender is one data source that feeds into XDR. They're not competing tools — XDR is the layer above that connects everything.
"How long before we're actually protected?" Most deployments are fully operational within 4–6 weeks. During rollout, we run in detection-only mode so we can tune without disrupting your operations. Once we go live, response is immediate.
"What happens when you find something?" We contain first, notify second. If we detect an active threat, we isolate the compromised account or device within minutes, then contact your designated point of contact with a full incident brief. You're never woken up for a false alarm — but you're always told when something real happens.
