+### About
+
+**RTCAgent** is a _next-generation **HEP Agent**_ developed using the latest **[eBPF](https://ebpf.io)** technologies.
+
+RTCAgent greatly differs from any other previous HEP Agent in several ways:
+
+- Unlike _native agents_, it does not require any code modifications or patches
+- Unlike _passive agents_, it does not require access to network interfaces and packets
+- Unlike _any other agent_, it traces functions used for _sending/receiving_ data
+
+_The result is a new, lightweight and portable HEP Agent able to mirror SIP packets through eBPF hooks<br>
+from the core of supported applications bypassing manual code integrations, network encryption and complexity._
