call, directly or through one of the available eBPF libraries. The verifier runs in a privileged context and performs static analysis to ensure that eBPF programs are safe for the kernel, or sometimes packet and socket-level view of all networking. This creates security systems operating with richer context and a better level of control than traditional solutions. Projects using eBPF for security purposes
