Microsoft Defender:
secure your endpoints and Microsoft 365 environment

Microsoft Defender for Business protects your endpoints, email and Microsoft 365 data against malware, ransomware and phishing. We configure, deploy and supervise Defender in your environment for consistent and centralised security.

Features

Defender protection for your IT

EDR: incident detection and response

Defender for Endpoint detects abnormal behaviour on your workstations in real time. In the event of an attack, automatic endpoint isolation and remediation recommendations limit propagation and reduce response time.

Anti-malware and antivirus protection

Real-time behavioural analysis on every endpoint. Defender identifies known malware and zero-day threats using Microsoft Security Graph intelligence — which analyses 65 billion signals per day.

Defender for Office 365: email protection

Advanced email filtering: malicious links neutralised before clicking (Safe Links), attachments analysed in a sandbox (Safe Attachments), identity spoofing detection (anti-phishing). Your users browse and communicate without risk.

Defender for Cloud Apps: shadow IT visibility

Identify all cloud applications used by your teams — including those you haven't authorised. Control access, block risky applications and enforce your security policies across all SaaS.

Vulnerability Management: patch before the attack

Continuous inventory of your endpoints and their vulnerabilities. Defender identifies outdated software, risky configurations and critical CVEs — and suggests remediation plans prioritised by risk level.

Native Microsoft 365 integration

Defender integrates natively into the Microsoft 365 ecosystem: Exchange, Teams, SharePoint, OneDrive. One console (Microsoft Defender XDR) to see your entire security posture, from endpoints to email.

The challenge

Your antivirus alone is no longer enough

  • You have an antivirus on every workstation — but no centralised visibility: you don't know if all machines are protected, up to date and healthy
  • Your emails travel without advanced protection: one malicious link or infected attachment is enough to compromise a machine, then spread ransomware across the entire network
  • Your employees use unauthorised cloud applications (shadow IT) to store and share data — without any control on your part
  • In the event of a security incident, you have no event timeline, no centralised log — investigation takes days and tracing the origin is often impossible
  • You have multiple security tools from different vendors — each with its own console, its own alerts and its own agents — impossible to get a coherent overall view

The Air Cloud approach to Microsoft Defender

We don't deploy Defender with one click — we build a security posture that matches your business context and maturity level.

Configuration tailored to your context

We first audit your attack surface: endpoints, email, cloud applications, remote access. We configure Defender with policies adapted to your sector, regulatory constraints and existing architecture — not a generic default configuration.

Your teams trained on security posture

We train your IT administrators on the Defender XDR console, reading alerts and incident response procedures. Your teams are self-sufficient in managing security day-to-day — not dependent on a provider for every alert.

Continuous supervision and monthly reporting

We supervise your Defender alerts and provide a monthly report on your security posture: incidents detected, remediation applied, recommendations for the next month. Security is not a one-off project — it is a continuous process.
