Defender types

Defenders enforce the policies you set in Console. They come in a number of different flavors. Each flavor is designed for protecting specific types of cloud-native resources and for optimal deployment into the environment, with full support for automated workflows. Use the following flow chart to choose the best Defender for the job.
In general, deploy Container Defender whenever you can. It offers the most features, it can simultaneously protect both containers and host, and nothing needs to be embedded inside your containers for Defender to be able to protect them.

Container Defender (Linux and Windows)

Install Container Defender on any host that runs a container workload. Container Defender protects both your containers and the underlying host. Docker must be installed on the host because this Defender type runs as a container.
Container Defender offers the richest set of capabilities. The deployment is also the simplest. After deploying Container Defender to a host, it can immediately protect and monitor your containers and host. No additional steps are required to rebuild your containers with an agent inside. Container Defender should always be your first choice whenever possible.
There are some minimum requirements to run Container Defender. You should have full control over the host where Container Defender runs. It must be able to run alongside the other containers on the host with select kernel capabilities. And it must be able to run in the host’s network and process namespace.
Deploy one Container Defender per host. Container Defender can be deployed in several ways:
  • With cluster constructs. Container orchestrators often provide native capabilities for deploying agents, such as Defender, to every node in the cluster. Prisma Cloud leverages these capabilities to install Defender. Kubernetes and OpenShift, for example, offer DaemonSets As such, Container Defender is deployed as a DaemonSet on Kubernetes
  • As a stand-alone entity. Stand-alone Container Defenders are installed on hosts that are not part of a cluster.

Host Defender (Linux and Windows)

Host Defender utilizes Prisma Cloud’s model-based approach for protecting hosts that do not run containers. This Defender type lets you extend Prisma Cloud to protect all the hosts in your environment, regardless of their purpose. Defender runs as a systemd service on Linux and a Windows service on Windows. If Docker Engine is detected on the host, installation of this Defender type is blocked; install Container Defender instead.
Deploy one Host Defender per host. Do not deploy Host Defender if you’ve already deployed Container Defender to a host. Container Defender offers the same host protection capabilities as Host Defender.

Serverless Defender

Serverless Defenders offer runtime protection for AWS Lambda functions. Serverless Defender must be embedded inside your functions. Deploy one Serverless Defender per function.

App-Embedded Defender

App-Embedded Defenders offer runtime protection for containers.
Deploy App-Embedded Defender anywhere you can run a container, but you can’t run Container Defender. Container-on-demand services are a typical use case for App-Embedded Defender. They abstract away the underlying cluster, host, operating system, and software modules (such as Docker Engine) and present them as a single black box. Hooks into the operating system that Container Defender needs to monitor and protect resources aren’t available in these environments. Instead, embed App-Embedded Defender directly inside the container to establish a point of control. Prisma Cloud supports an automated workflows for embedding App-Embedded Defenders.
Deploy one App-Embedded Defender per container. For Fargate, deploy one Defender per task.
App-Embedded Defender offers three deployment mechanisms: Fargate, Dockerfile, and manual.


If you have an AWS Fargate task, deploy App-Embedded Fargate Defender.
A key attribute of the App-Embedded Fargate Defender is that you don’t need to change how the container images in the task are built. The process of embedding the App-Embedded Defender simply manipulates the task definition to inject a Prisma Cloud sidecar container, and start existing task containers with a new entry point, where the entry point binary is hosted by the Prisma Cloud sidecar container. The transformation of an unprotected task to a protected task takes place at the task definition level only. The container images in the task don’t need to be manually modified. This streamlined approach means that you don’t need to maintain two versions of an image (protected and unprotected). You simply maintain the unprotected version, and when you protect a task, Prisma Cloud dynamically injects App-Embedded Defender into it.
The Prisma Cloud sidecar container has a couple of jobs:
  • Hosts the Defender binary that gets injected into containers in the task.
  • Proxies all communication to Console. Even if you have multiple containers in a task, it appears as a single entity in Console’s dashboard.
  • Synchronizes policy with Console and sends alerts to Console.


The Docker image format, separate from the runtime, is becoming a universal runnable artifact. If you’re not using Fargate, but something else that runs a Docker image, such as Azure Container Instances, use the App-Embedded Defender with the Dockerfile method.
Provide a Dockerfile, and Prisma Cloud returns a new version of the Dockerfile in a bundle. Rebuild the new Dockerfile to embed Prisma Cloud into the container image. When the container starts, Prisma Cloud App-Embedded Defender starts as the parent process in the container, and it immediately invokes your program as its child.
There are two big differences between this approach and the Fargate approach:
  • With the Fargate approach, you don’t change the actual image. With the Dockerfile approach, you have the original image and a new protected image. You must modify the way your containers are built to embed App-Embedded Defender into them. You need to make sure you tag and deploy the right image.
  • Each Defender binary makes it’s own connection to Console. In the Console dashboard, they are each counted as unique applications.
Nothing prevents you from protecting a Fargate task using the Dockerfile approach, but it’s inefficient.


Use the manual approach to protect almost any type of runtime. If you’re not running a Docker image, but you still want Prisma Cloud to protect it, deploy App-Embedded Defender with the manual method. Download the App-Embedded Defender, set up the required environment variables, then start your program as an argument to the App-Embedded Defender.
If you choose the manual approach, you have to figure out how deploy, maintain, and upgrade your app on your own. While the configuration is more complicated, it’s also the most universal option because you can protect almost any executable.

Tanzu Application Service Defender

Tanzu Application Service (TAS) Defenders run on your TAS infrastructure. TAS Defenders provide nearly all the same capabilities as Container Defenders, as well as the ability to scan droplets in your blobstores for vulnerabilities. For specific differences between TAS Defenders and Container Defenders, see the TAS Defender install article.
The TAS Defender is delivered as a tile that can be installed from your TAS Ops Manager Installation Dashboard.
