# Introduction to Pangolin

> Connect and protect your users with an open-source networking and security platform

Pangolin is an open-source SASE platform with one mission: connect and protect your users, wherever they are.

It treats networking and security as a single system. Identity, sites, access control, privileged access, and an identity-aware AI gateway share one policy model. The idea is the same as platforms like Cloudflare One, Zscaler, and Prisma Access, but Pangolin is open, self-hostable, and built to stay light enough that administrators actually enjoy running it.

## Why Pangolin Exists

Legacy SASE platforms got the idea right: connectivity and security belong together. They delivered it as a heavyweight, closed, cloud-locked stack. Pangolin does that unification in the open, on infrastructure you control, and simple enough to deploy yourself.

* **Open source and auditable.** You can see how traffic is handled and how access decisions get made.
* **Networking and security as one platform.** Connecting users and protecting them happen together, with one identity and policy model.
* **Lightweight by design.** The control plane runs on a modest server. A user-space connector sits in your private networks.
* **Zero trust from day one.** Access is granted per resource, with identity providers, roles, and audit logs.
* **Run it your way.** Self-host or use [Pangolin Cloud](https://app.pangolin.net/auth/signup).

## Core Concepts

Pangolin is organized around a few pieces you will use everywhere:

1. A **server** is the control plane. It holds identity, policy, and coordination. You can use [Pangolin Cloud](/about/pangolin-cloud-vs-self-hosted) or [self-host](/self-host/quick-install) the same software.
2. **[Sites](/manage/sites/understanding-sites)** connect the networks where your applications and infrastructure live.
3. **[Resources](/manage/resources/understanding-resources)** are the specific things users are allowed to reach: web apps, SSH, desktops, private hosts, and AI providers.
4. **[Clients](/manage/clients/understanding-clients)** give devices a private path to those resources.
