An enterprise security team is researching a new security architecture to better protect the company’s networks and applications against the latest cyberthreats. The company has a fully remote workforce. The solution should be highly redundant and enable users to connect to a VPN with an integrated, software-based firewall. Which of the following solutions meets these requirements?

SASE (Secure Access Service Edge) is the correct answer because it integrates networking and security functions into a single, cloud-delivered service. This architecture is ideal for a fully remote workforce as it provides secure access to resources from anywhere, incorporating VPN capabilities and software-defined firewalls. SASE inherently offers high redundancy through its cloud-native design. IPS (Intrusion Prevention System) is a component of a security architecture, not a complete solution for these requirements. SIEM (Security Information and Event Management) is for logging and analysis, not network security architecture. CASB (Cloud Access Security Broker) focuses on securing cloud application usage but doesn't encompass the full network and security integration needed here.
