Linux runtime security agent powered by eBPF
Summary: Pulsar is a modular and fast runtime security framework for IoT devices, powered by eBPF. It monitors Linux device activity at runtime, collecting events from the kernel safely and efficiently. Pulsar's core modules use eBPF probes to gather data on file I/O, network, processes, and system activity. Its modular design allows easy adaptation for new use cases, module creation, and custom rule writing. Pulsar requires a kernel 5.5 or higher with BPF and BTF enabled.
