## What it is
Pulsar is a modular, eBPF-powered runtime security and observability tool for Linux devices, written in Rust and designed for IoT and edge environments. It collects kernel-level events (processes, file I/O, network, system activity) and evaluates them against user-defined security rules to detect and alert on threats.

## Use cases
- monitor runtime activity of embedded linux devices
- detect suspicious file access like symlink to /etc/shadow
- monitor network connections for suspicious activity
- detect process execution and behavior changes on iot devices
- write custom security policies for linux endpoints
- secure containers and servers with eBPF-based monitoring

## When to choose
- you need lightweight runtime security on IoT or embedded Linux devices
- you want eBPF-based monitoring without kernel modules or patching
- you need modular, customizable security rules with a human-readable format
- you run Arm, RISC-V, or x86 Linux systems and want unified security observability

## When to avoid
- you need runtime security on non-Linux platforms
- your kernel is older than 5.5 or lacks BPF/BTF support
- you need a full SIEM or centralized log management solution rather than a device-level agent
