How does Microsoft Defender for Endpoint protect against cyberattacks?

Microsoft Defender for Endpoint employs a multi-layered approach to protect your organization from cyberattacks. By combining advanced threat detection, prevention, and response capabilities, it helps you stay ahead of evolving threats and safeguard your endpoints.

How does it prevent cyberattacks?

To prevent cyberattacks, Microsoft Defender for Endpoint reduces potential vulnerabilities by enforcing security policies through attack surface reduction. These policies limit entry points for attackers, such as restricting applications or controlling network access. Additionally, its next-generation protection employs AI and machine learning to identify and block malware, ransomware, and phishing threats in real time. It identifies and prevents access to apps considered unsafe, even if they don’t qualify as malware. It also includes robust web and network protection, which prevents access to malicious websites or low-reputation internet destinations, further reinforcing your defenses. 

How does it detect cyberattacks?

Detection capabilities are powered by behavioral analytics, which continuously monitor endpoint activities to identify suspicious patterns indicative of threats. The solution also employs endpoint detection and response (EDR) to analyze data from endpoints in real time, generating alerts and actionable insights for further investigation. Enhanced by Microsoft’s global threat intelligence, Defender for Endpoint identifies attacker tools, techniques, and methods, allowing for timely and accurate detection of potential breaches.

How does it respond to cyberattacks?

When a cyberattack occurs, it automates investigations and remediation processes to address threats efficiently. It isolates compromised devices to contain the threat and prevent lateral movement within your network. For more complex incidents, Defender provides support through Microsoft Threat Experts, offering expert analysis and targeted notifications to enhance your response efforts. Together, these capabilities minimize the impact of attacks while reducing the workload on your IT team.
