# Securing n8n

Securing your n8n instance can take several forms.

At a high level, you can:

- Conduct a [security audit](../security-audit/) to identify security risks.
- [Set up SSL](../set-up-ssl/) to enforce secure connections.
- [Set up Single Sign-On](../set-up-sso/) for user account management.
- Use [two-factor authentication (2FA)](../../../user-management/two-factor-auth/) for your users.

More granularly, consider blocking or opting out of features or data collection you don't want:

- [Disable the public API](../disable-public-api/) if you aren't using it.
- [Opt out of data collection](../telemetry-opt-out/) of the anonymous data n8n collects automatically.
- [Block certain nodes](../blocking-nodes/) from being available to your users.
- [Restrict account registration](../restrict-by-email-verification/) to email-verified users.
