Which network architecture leverages cloud technology for security functions?

The correct answer is Secure Access Service Edge (SASE). This network architecture integrates various security and networking capabilities into a single cloud service model. SASE combines wide area networking (WAN) capabilities with security functions such as secure web gateways, firewall as a service, and zero trust network access, effectively bringing security closer to the user's location, regardless of where they connect.

This architecture is designed to address the needs of modern enterprises that require flexibility and scalability while ensuring a robust security posture as employees access resources from various locations, including remote and mobile environments. By leveraging cloud technology, SASE enhances security while maintaining network performance and speed, adapting to the dynamic nature of today's workforce and the increasing trend of cloud adoption.

In contrast, traditional firewall setups are typically on-premises solutions that lack the flexibility and scalability associated with cloud architectures. Remote access VPN solutions and virtual private networks primarily focus on providing secure connections to private networks but do not encompass the comprehensive security framework and cloud integration that SASE offers.
