## What it is
Sliver is an open-source cross-platform adversary emulation and red team framework written in Go. It generates dynamically compiled implants with secure command-and-control over mTLS, WireGuard, HTTP(S), and DNS, plus post-exploitation features like process injection and pivoting.

## Use cases
- run red team engagements with secure C2 channels
- emulate adversary tactics during security testing
- generate obfuscated cross-platform implants
- test blue team detection of DNS and HTTP C2 traffic
- perform post-exploitation like process injection and token manipulation
- pivot through compromised hosts via TCP and named pipes
- collaborate with a team on penetration testing operations

## When to choose
- you need an open-source alternative to commercial C2 frameworks like Cobalt Strike
- your red team operates across Windows, Linux, and macOS targets
- you want encrypted, resilient C2 over mTLS, WireGuard, HTTPS, or DNS
- you need a scriptable framework with Python bindings and multiplayer support

## When to avoid
- you only need a vulnerability scanner rather than a post-exploitation C2 framework
- you lack authorization to perform offensive security testing
- you need a lightweight agent without dynamic payload generation
- your targets are mobile or embedded platforms outside Go's supported OS targets
