# Introduction

Deka Guard is one of Service Portal Cloudeka that allows you to create, manage, and granularly enforce network communication rules in a Kubernetes environment. There are several main functions provided by Deka Guard including the following.

1. **Filtering traffic between pods (Ingress & Egress)**

   You can restrict pods to only communicate with certain pods, certain IPs, or certain ports.
2. **Label and namespace-based network segmentation.**

   You can define what labels are allowed to communicate with each other, thus building isolation between applications.
3. **Default Deny & Whitelisting Rules**

   You can support configuring all traffic to be denied, then explicitly allow certain access.
4. **GUI Management**

   Compared to writing YAML manually, Deka Guard simplifies policy management through a friendly user interface.
