What is Microsoft Defender?
Microsoft Defender is an AI-powered device security solution designed to help protect your business from cyberthreats like ransomware, malware, and phishing attacks. It integrates with Microsoft 365 and offers security capabilities that are tailored to meet the needs of businesses with limited IT resources, requiring minimal setup.
With Defender, you can protect up to 5 devices per user, ensuring your entire organization is protected from potential cyberthreats.
Identify security gaps
Defender helps identify and prioritize the most critical software vulnerabilities and misconfigurations, giving you clear recommendations to strengthen your security.
Protect device and data security
Defender helps shield your devices from malware, or malicious software, which can damage, disrupt or gain unauthorized access to your devices or network. These threats can compromise your devices or data and are designed to steal or damage your personal data, track or spy on you, steal your money or use your device to harm others. Defender minimizes the areas across devices that are open to attacks and reinforces security with anti-malware and antivirus protection.
Detect and respond to attacks
Using AI-powered signals, Defender offers endpoint detection and response to help you detect, disrupt, and address cyberattacks. It continuously monitors your network for suspicious activities, enabling rapid response to emerging threats and minimizing potential damage.
Recover from cyberattacks and strengthen security
If a cyberattack occurs, Defender automatically investigates and resolves most threats with automated responses. It sends you recommendations on next steps, insights into how the breach might’ve occurred, and tips to help minimize the risk of future incidents.
