What is Microsoft Defender for Business?
Defender for Business is Microsoft's endpoint security solution designed for organisations with up to 300 users. It brings the same AI-powered detection and response Microsoft uses at enterprise scale down to a price point that works for SMBs, with simple wizard-based onboarding and out-of-the-box policies.
Core Capabilities
Next-Generation Antivirus
AI-powered antivirus blocks emerging threats, zero-day exploits, and fileless malware that traditional antivirus misses.
Endpoint Detection & Response
EDR with automatic attack disruption isolates compromised devices in real time and contains ransomware before it spreads.
Threat & Vulnerability Management
Continuously identifies software vulnerabilities and misconfigurations across your fleet, prioritising them by risk.
Attack Surface Reduction
Hardens devices against common exploit techniques with rules targeting macros, scripts, and suspicious executable behaviour.
Automated Investigation & Response
AI triages alerts, investigating root causes, and remediating threats. But technology alone isn't enough. We're behind it all, stepping in when human judgement is needed.
Cross-Platform Device Coverage
Protects Windows, macOS, iOS, and Android from a single console. Server protection available as an add-on.
