    Twenty - Hardened Self-Hosted Open-Source CRM

    This product has charges associated with it for hardening, security configuration, and support. Twenty is a self-hosted open-source CRM with kanban pipelines, custom objects, GraphQL API, multi-workspace support, and OAuth (Google, Microsoft) - a modern Salesforce and HubSpot alternative that runs as a Node and Postgres docker-compose stack with a bundled React front. Unlike bare Twenty AMIs that ship on 0.0.0.0:3000 with no TLS, default credentials, open signup, and a trivially-guessable APP_SECRET, this Lynxroute build is ready out of the box: first owner seeded at first boot, signup auto-locked to single-tenant, 64-char APP_SECRET randomized per launch, web UI bound to loopback and reachable only through Nginx with TLS and WebSocket support, Postgres and Redis on the docker bridge only, UFW pre-configured, and a CIS Level 1 hardened Ubuntu 24.04 LTS base. AGPL-3.0 license - fully auditable, no vendor lock-in.

    Overview

    This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.

    WHAT IS TWENTY

    Twenty is an open-source self-hosted CRM - a modern, opinionated alternative to Salesforce and HubSpot. The stack runs as four docker containers: a NestJS server that exposes the REST and GraphQL APIs and serves the bundled React front on TCP 3000, a NestJS worker that processes BullMQ background jobs (record imports, calendar sync, email notifications), a PostgreSQL 16 database, and a Redis 7 cache and queue backend. The web UI gives sales and operations teams kanban pipelines for opportunities and deals, contact and company records, custom objects with arbitrary fields and relations, multi-step workflows, public-share views, and a GraphQL API for integrations. Built-in connectors (Google, Microsoft) sync calendars and inbox events into the CRM. Multi-workspace mode lets one server back several teams or customers. AGPL-3.0 license, no vendor lock-in. The core differentiator vs. SaaS alternatives is sovereignty: customer records, deals, custom objects, and OAuth tokens stay on your own AWS account - none of it transits a third-party CRM cloud.

    WHAT THIS AMI ADDS

    Security hardening:

    • First owner seeded at first boot via the GraphQL signUpInWorkspace mutation - email admin@lynxroute.local , password set to the EC2 Instance ID, change from Settings on first login
    • Signup auto-locked after the owner is created - IS_MULTIWORKSPACE_ENABLED=false makes the GraphQL mutation reject every subsequent signup with SIGNUP_DISABLED, so a public AMI cannot be hijacked by a stranger registering before you log in
    • APP_SECRET (64 chars, base64) randomized at first boot - the master key for JWT access, refresh, login, and file tokens is unique per AMI launch, never baked
    • Postgres password (32 chars, A-Za-z0-9) and Redis password (32 chars) generated at first boot and written into /opt/twenty/.env - never baked into the AMI
    • All four containers reachable only via the docker bridge - the host port 3000 is bound to 127.0.0.1 only, the only public-facing endpoint is Nginx on TCP 443
    • Nginx reverse proxy with self-signed TLS, HTTP-to-HTTPS redirect, WebSocket upgrade for graphql-ws subscriptions, and security headers
    • Redis password-protected with AOF persistence enabled
    • All four container images pre-pulled at build time so first launch is fast and not dependent on Docker Hub availability
    • Docker daemon log rotation pre-configured to prevent json-file logs from filling the root volume
    • UFW firewall pre-configured - only TCP 22, 80, 443 are exposed
    • fail2ban, AppArmor
    • CVE scan - every image is scanned for vulnerabilities before release

    OS hardening (CIS Level 1):

    • CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
    • auditd, SSH hardening, kernel hardening, IMDSv2 enforced

    Compliance artifacts:

    • SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
    • CIS Conformance Report at /etc/lynxroute/cis-report.html
    • CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md

    Highlights

    • Twenty CRM security baked in: first admin seeded at first boot, sign-up auto-locks to single-tenant after the owner is created, session and database secrets randomized per instance, the CRM reachable only through Nginx with TLS, and the database kept on the internal container network - unlike bare Twenty AMIs that expose the CRM with no TLS, hard-code the session signing secret, ship the default database password, and leave sign-up open so a stranger can claim your CRM before you log in.
    • CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
    • Full CRM stack on by default: NestJS server with bundled React front, BullMQ worker for background jobs, Postgres 16, Redis 7 - all four container images pre-pulled into the AMI so first launch is fast and self-contained. Schema migrations run automatically on first boot. AGPL-3.0 license, no vendor lock-in.

    Amazon Machine Image (AMI)

    An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

    Additional details

    Usage instructions

    1. Launch instance (t3.large recommended for typical team use, t3.medium minimum)
    2. Open Security Group - allow TCP 443 from your IP only (very important - the first browser to reach the URL can claim the admin role), allow TCP 80 if you want Let's Encrypt
    3. SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
    4. Read connection details: sudo cat /root/twenty-credentials.txt
    5. Open https://<PUBLIC_IP>/ in your browser - accept the self-signed certificate warning
    6. Click "Sign up" on the Twenty welcome screen and register with YOUR real email - the first registered user becomes the workspace owner and admin
    7. After your registration, signup auto-locks (subsequent attempts return SIGNUP_DISABLED). Verify in sudo systemctl status twenty-register-watch that the first workspace was detected.
    8. Invite teammates from Settings -> Members -> Invite (only invited members can join from now on)
    9. (Recommended) Once registered, widen the Security Group on TCP 443 back to the audience you want.
