The Drug Abuse category is set to Block, which denies access and displays a replacement message to the user.

Implicit Measurement: In FortiOS, once a Performance SLA (Health Check) is configured with an Active probe mode (as seen in the exhibit with Ping selected), the FortiGate automatically begins calculating three key quality metrics for every member interface: Latency, Jitter, and Packet Loss.
Visibility: Even without an SLA Target defined, these real-time measurements are visible in the SD- WAN Monitor and via the CLI command diagnose sys virtual-wan-link health-check
<SLA_Name>.
Active Probes: Because the probe mode is set to Active using the Ping protocol, the FortiGate sends synthetic packets at the defined Check interval (500ms in the exhibit). It calculates jitter by measuring the variation in the round-trip time (RTT) between these consecutive probes.

"If a flow is identified as belonging to a defined application category (such as social media), FortiGate will match it to the corresponding service rule (rule 2) and route it through the specified interface, such as port2. However, if the application is not recognized during the session setup, the system defaults to load balancing the traffic using the available tunnels according to the policy for unclassified traffic, ensuring continuous connectivity while waiting for application classification." This guarantees both performance and resilience.

FortiSASE includes inline CASB capabilities, enforcing cloud application controls directly on user traffic. API-based CASB is not included in FortiSASE.

Secure Internet Access (SIA): This enables secure web browsing by applying security profiles such as Web Filter, Anti-Malware, and SSL Inspection in the SASE cloud. It protects remote users from internet-based threats regardless of their location.
Secure Private Access (SPA): This provides granular, explicit access to private applications hosted in data centers or the cloud. It is achieved through ZTNA (Zero Trust Network Access) for session-based security or through SD-WAN integration where FortiSASE acts as a spoke to an existing corporate SD- WAN hub.
SaaS Security: FortiSASE utilizes Inline-CASB and Shadow IT visibility to monitor and control the use of cloud applications. Data Loss Prevention (DLP) is integrated into these workflows to prevent sensitive corporate data from being uploaded to unauthorized SaaS platforms.
