Antivirus and Anti-Malware Protection

Defender for Business includes advanced antivirus and anti-malware features, shielding your company’s systems from malicious software, phishing attacks, and ransomware. This feature is integrated into Office 365 Defender, protecting your organization’s Outlook and application suite.

Endpoint Detection and Response (EDR)

The endpoint detection and response feature is crucial for identifying suspicious activities across your devices. Defender for Business automatically detects anomalies and either takes action to mitigate them or alerts the security team for further investigation.

Threat and Vulnerability Management

Proactively managing threats is a key element of any security strategy. Defender for Business monitors vulnerabilities across your systems, allowing you to address potential risks before they can be exploited.

Attack Surface Reduction

By reducing the attack surface, Defender for Business minimizes the points of entry that malicious actors can exploit. It helps protect your network from unauthorized access and limits the exposure of sensitive data.

Seamless Integration with Microsoft Solutions

Defender for Business integrates smoothly with the Microsoft ecosystem, enhancing security across your entire suite of tools. Key integrations include:

Microsoft Entra ID

Entra ID helps manage user identities and access, making it a critical part of your security infrastructure. By managing identity and access across devices, Defender for Business supports safe remote work environments, ensuring only authorized personnel have access to sensitive resources.

Microsoft Defender for Office 365

Office 365 is a primary target for many cyber-attacks. With Defender for Office 365, you get real-time protection from phishing emails, malicious links, and other security risks that could compromise your business’s data.

Intune Plan 1

For mobile security, Intune Plan 1 allows you to manage and secure mobile devices and applications. This feature is perfect for companies with remote workers or bring-your-own-device (BYOD) policies, offering security for corporate and personal devices alike.

Protection for All Devices

Whether your employees are working from home or the office, Defender for Business secures all endpoints. From desktops to smartphones, this solution provides comprehensive protection across multiple device types. SMBs no longer need to worry about a device being left unprotected, as Defender covers all potential access points to your network.
