What type of attacks does Sophos Email Security primarily protect against?

Sophos Email Security is designed specifically to combat threats that originate through email communication. One of its primary functions is to detect and prevent phishing attacks, which are attempts to deceive recipients into providing sensitive information. This solution also effectively filters out spam, which can clutter inboxes and often serves as a vehicle for malicious content or further phishing attempts. By focusing on these areas, Sophos Email Security helps organizations safeguard their communication channels against the potential risks associated with phishing and spam, thereby reducing the likelihood of data breaches and financial loss.

The other options either involve different types of threats or security measures that are not the primary focus of Sophos Email Security. For instance, while malware and ransomware attacks are critical areas of concern, they might be addressed through different cybersecurity solutions rather than specifically through email protection. Similarly, DDoS attacks are related to network availability and performance rather than email security, and insider threats focus on internal risks rather than email-originated external threats. Data leaks, while critical to address, are also often managed through data loss prevention (DLP) solutions rather than email security alone.
