What does FortiSASE do to prevent unauthorized access?

FortiSASE enhances security by enforcing security policies and detecting threats in real time, which is crucial for preventing unauthorized access. This proactive approach allows the system to continuously monitor network traffic and user activity, applying defined security rules to ensure that only legitimate users can access resources. By identifying and responding to potential threats instantaneously, FortiSASE can mitigate risks before they escalate into security breaches.

Other options, while they may contribute to an overall security strategy, do not specifically address the immediate prevention of unauthorized access in the same direct manner as real-time threat detection and policy enforcement. Regular software updates and patches, for example, are important for maintaining the security posture but do not actively prevent unauthorized access. The concept of limiting access to only authorized IP addresses can be effective, but it may not encompass the dynamic nature of user behavior and potential threats that FortiSASE is designed to address. Finally, operating without a firewall undermines the fundamental security measures that protect networks, making this option counterproductive to the goal of preventing unauthorized access.
