For self-hosted n8n, that also means configuring HTTPS and encrypted storage yourself; n8n Cloud’s managed protections do not automatically apply to self-hosted installations.
Put self-hosted n8n behind HTTPS
For a self-hosted deployment, n8n recommends placing a reverse proxy such as Traefik or a Network Load Balancer (NLB) in front of the instance. The proxy handles TLS and can manage certificate renewal. Follow n8n’s SSL setup instructions for your deployment.
n8n also documents passing a certificate and key directly to the application. With that approach, you are responsible for keeping the certificate current and renewed. Neither arrangement is universally best: choose based on how your infrastructure is deployed and who will maintain certificates.
HTTPS protects data in transit between users or connected services and the instance. Self-hosters must also address data at rest—for example, by using encrypted storage for n8n and its database. n8n describes TLS and encrypted storage as managed protections for n8n Cloud; do not assume they are configured for a self-hosted instance. See n8n’s security statement.

- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Limit user access and understand what 2FA covers
Give people only the access they need, and review permissions when responsibilities change. Where available, use n8n’s security policies to enforce two-factor authentication (2FA) for users who sign in with email and password.
That enforcement does not cover SAML or OIDC single sign-on (SSO) logins. Security-policy controls also depend on plan and licensed features: n8n lists them for Cloud Enterprise and self-hosted Business and Enterprise. Check the current security-policy documentation to confirm what your instance supports.

Treat workflow sharing as access to connected services
Sharing a workflow has an important credential consequence: n8n says editors can use all credentials referenced by that shared workflow, including credentials that were not independently shared with them. In practical terms, someone who can edit a workflow may be able to operate integrations connected through it.
- Before sharing, check who can edit the workflow and which external accounts its nodes use.
- Grant workflow access only to people who should be able to work with those connected services.
- Review existing shares when a person’s role changes or a workflow’s integrations change.
See n8n’s workflow-sharing documentation for the permission behavior.

Run the security audit to find common risks
n8n’s built-in audit checks five areas: credentials; database-query expressions and parameters; file-system interactions; built-in, community and custom nodes; and instance issues. Instance findings can include unprotected webhooks, missing security settings and whether the instance is outdated. Credential findings can include credentials that are unused or not used by active or recently active workflows.
Run an audit using one of these documented methods:

Pay particular attention to audit findings for unprotected webhooks. A webhook can be an externally reachable entry point into a workflow, so investigate each finding and confirm that the endpoint’s access controls fit its intended use. The audit can surface exposure, but its result alone does not establish that every webhook or workflow is safe.

n8n’s broader security overview also describes controls such as SSO, encryption-key rotation, task-runner hardening, execution-data redaction, disabling the public API, blocking specific nodes, SSRF protection and restricting registration to email-verified users. Availability and applicability vary by deployment and licensed features; check the documentation for the current requirements.
Keep source-controlled workflow files private when needed
If you use n8n source control, make the repository private unless you intend its contents to be public. n8n notes that source-controlled data can include workflows, tags, variable stubs and credential stubs. Review repository visibility and access in line with what you commit. See n8n’s source-control environment guidance.
