What software protects devices against ransomware and zero-day attacks?

There are several software solutions that offer protection against ransomware and zero-day attacks, utilizing a combination of antivirus, anti-malware, and advanced threat detection technologies. Here are some notable options:

1. **Microsoft Defender Antivirus** - Built into Windows 10 and later, it provides real-time protection against a variety of threats, including ransomware and zero-day attacks.

2. **Bitdefender** - Offers advanced protection features such as ransomware remediation and behavioral detection capabilities to identify potential zero-day exploits.

3. **Norton Antivirus** - Includes ransomware protection and additional layers of security to help defend against zero-day vulnerabilities and emerging threats.

4. **Kaspersky** - Features a robust suite that includes anti-ransomware technology and proactive detection of new threats.

5. **McAfee** - Provides comprehensive security with ransomware protection and real-time threat intelligence capabilities.

6. **CrowdStrike Falcon** - An endpoint detection and response (EDR) platform that uses behavioral analysis and machine learning to pinpoint and mitigate zero-day attacks and ransomware.

7. **Sophos Intercept X** - Combines deep learning malware detection with anti-ransomware technology, aiming to stop not only known threats but also zero-day exploits.

8. **Trend Micro** - Offers layered defenses against ransomware and employs techniques such as behavioral monitoring to guard against zero-day threats.

9. **Webroot** - Utilizes cloud-based threat intelligence to quickly respond to emerging threats, including ransomware and zero-day vulnerabilities.
