Integrated defense across endpoints, identity, email and cloud apps: Microsoft telemetry that correlates where others just add up.

01 · What it is

Microsoft Defender XDR, made clear.

Defender XDR joins signals from endpoints (Defender for Endpoint), identity, email (Defender for Office) and cloud apps into correlated incidents: the phishing, the suspicious login and the anomalous process become ONE story with a timeline. The response — isolate, revoke, block — starts from the same console.

Automatic response + analystcontain first, understand right after
Sentinel for the total viewthe SIEM on top, if needed
From scattered signals to the attack story

Complete onboarding

XDR pays off with all fronts active: endpoints, mail and identity together, not just the antivirus.

Automation tuning

What to isolate automatically and what to hand to the analyst: the rules that avoid damage and noise.

Attack surface reduction

The ASR rules closing ransomware's favorite doors: macros, scripts, credential theft.

Integration with our NOC

Defender incidents enter the YoctoIT flow: tickets, escalations and reports as for the whole estate.

03 · In depth

XDR: signals, incidents and automation

Defender XDR joins Endpoint (EDR with ASR rules and device control), Office (mail and collaboration), Identity (the old ATA on the DC), Cloud Apps (CASB): the correlation engine merges alerts into incidents with the kill chain, automated investigation solves the standard cases, advanced hunting (KQL) queries 30 days of raw telemetry. The link to Sentinel brings everything into the SIEM with bi-directional sync.

  • ASR rules — attack surface reduction: macros, scripts and credential theft closed by policy
  • Automated investigation — the AIR that investigates and remediates repetitive cases on its own
  • Advanced hunting — KQL on processes, mail and identity: hunting with a single language
  • Deception — native honeytokens: the attacker who gives himself away
  • Secure score — the posture measured with prioritized actions
  • Sentinel sync — bi-directional incidents with the SIEM: a single workflow

05 · Use cases

Where it really pays off.

Modern endpoint defense

Real EDR instead of the 2015 antivirus.

Serious anti-phishing

The malicious mail traced to the last click.

A boosted SOC

Fewer alerts, more stories: the analyst works on the signal.

Attacks correlate on their own — the defense must do the same: XDR managed within our 24/7 perimeter.
