# Ringfence rules

Ringfencing is designed to mitigate the security risk of transmission of malware between user devices such as laptops when they are sitting on a public network. Ringfence rules can block inbound and/or outbound local traffic except that which is required to establish the tunnel to the Gateways.

## Before you start

Background information:

- Learn about Ringfencing in [Device and Client controls](/v1/docs/device-and-client-controls)
- Learn more about access controls in [Access for Users/Devices](/v1/docs/userdevice-access)
- To assign new Ringfence rules refer to [Policy Configuration](/v1/docs/configure-policies)

> [!NOTE]
> **NOTE**
> 
> Ringfence rules cannot be controlled by Conditions.

Use the Ringfence rules form for:

- Adding ALLOW or BLOCK rules that will be applied to the Client machines

For details on completing the form, refer to [configure ringfence rules](/v1/docs/configure-ringfence-rules)

## Bulk Actions

The Admin UI tools page provides [more information](/v1/docs/admin-ui-tools) about the bulk actions that can be performed on multiple Ringfence rules at one time.

A Policy is a set of rules that govern access control and permissions for users and devices within the Appgate ZTNA system. Policies determine what resources users can access based on their entitlements.
