# Welcome to Paragon

> Embedded integration infrastructure for B2B SaaS & AI products

Paragon is an all-in-one embedded platform for building native product integrations that connect your product with your customers’ 3rd-party SaaS apps, without the plumbing.

The core platform provides you the building blocks for every integration ([130+ native connectors](/resources/integrations) as well as a [custom integration builder](/resources/custom-integrations)), including:

* An embedded SDK to build seamless in-app integration experiences, with a white-labeled [Connect Portal](/connect-portal/) (or build your own UI with a [headless](/connect-portal/headless-connect-portal) implementation)
* Multi-tenant architecture that keeps every one of your customer’s data and integration configuration isolated
* Fully managed integration [authentication](/getting-started/displaying-the-connect-portal) (OAuth 2.0/API Keys) for every integration
* Detailed event logs for enterprise-ready [monitoring and observability](/monitoring/overview)
* Flexible [deployment](/on-premise/choosing-a-hosting-solution) options: cloud, on-premise, or forward-deployed

  <Tab title="Managed Sync">
    ### Managed Sync

    **Managed Sync** provides two easy-to-use APIs to pull high volumes of data from your users' integrations into your app, while respecting the data's underlying permissions:

    * Sync API: Enable full syncs of your users' 3rd-party data with two API calls
    * Permissions API: Enforce access control on ingested 3rd-party data in RAG

    ### Highlights

    * Declarative ingestion jobs for files, CRM records, tickets, accounting data, and more
    * Automatic backfill + incremental sync with failure recovery
    * Record/document Permissions API for downstream queries
    * Scale to hundred of millions of records without managing infrastructure

    ### Common Use Cases

    * Knowledge ingestion for RAG (ie. files, knowledge bases, meeting transcripts, chat)
    * Structured data ingestion (ie. CRM, accounting, ticketing)
