What are the components of endpoint protection against social engineering attacks?

Social engineering attacks frequently leverage email (e.g., phishing, spear-phishing) to trick users into revealing information or clicking malicious links. A Cisco Secure Email Gateway provides essential protection by filtering malicious emails, identifying impersonation attempts, and blocking suspicious attachments, thus acting as a primary defense for endpoints against these threats.

IPsec is used for securing network communication channels through encryption and authentication, not directly for protecting endpoints against social engineering tactics themselves.

A firewall protects endpoints by controlling network traffic ingress and egress, but it doesn't typically inspect email content or identify social engineering lures within messages, which are the primary vectors for such attacks.

An Intrusion Detection System (IDS) monitors network or host activities for malicious patterns but is reactive; it doesn't proactively filter or block the delivery of social engineering emails to an endpoint.
