With Probely's plugin you can automatically start a scan every time your Jenkins pipeline is executed.

Jenkins allows you to have an arbitrary number of build and test scenarios, but a common pattern is as follows:

  • Build step: compiles the application or creates the Docker containers

  • Deploy step: sends the compiled code or the containers to test server and execute them

  • Test step: execute tests on the running application

The Probely plugin is a build task, that should run after the application is built and deployed.
It is recommended that the security tests run after the integration/functional tests pass, to ensure the application is working properly. A broken application may cause security tests to miss vulnerabilities because a particular feature is not working.

Installation and setup

Installing and setting up the plugin will take you less than 5 minutes.

1. Open Jenkins and click on Manage Jenkins

2. Click on Manage Plugins

3. Click on Available tab

4. On the Filter search box, enter probely
5. Select the Probely Security Scanner plugin
6. Click on Download now and install after restart
7. After Jenkins restarts, the plugin will be installed. Continue reading to setup the required Probely API key.

Generating an API key

Before using the plugin, you first need to create an API key for Jenkins to be able to start a scan with Probely.

If you are using the normal version of Probely (Pro and Premium plan) follow these instructions:

1. Go to https://app.probely.com and log in
2. Select a target from the drop-down list
3. Go to the Settings page
4. Click on the Integrations tab
5. Write a name for the API Key. Since we want this API Key for Jenkins, we name it Jenkins
6. Click on Generate New Key

If you are using the enterprise version, follow these instructions:

  1. Go to https://plus.probely.app/ and log in

  2. Go to the Target tab and click on the target

  3. Click on the Settings button

  4. Click on the Integrations tab

  5. Write a name for the API Key. Since we want this API Key for Jenkins, we name it Jenkins

  6. Click on Generate New Key

After the API key is created, please take note of the Target id and API key values. They will be required to configure the Plugin credentials later on.

Configuring the plugin

The plugin can be used in both Freestyle and Pipeline projects, and this post will provide an example for each one. You can learn more about these two project types and their differences here.

Configuring credentials

1. Click on Credentials
2. Click on the down arrow near (global) to enable the dropdown menu and choose Add credentials

1. On the Kind dropdown menu, choose Secret text
2. Enter the API key in the Secret textbox
3. Enter a value for the credentials in the ID textbox, for example probely-test-site
4. Enter an optional Description and click OK

Using the plugin in a Freestyle project

Creating a freestyle is the simplest way to have a repeatable process to build and test your application, especially for simple applications with just a few jobs.
If you already have a freestyle project you only need to configure the plugin: in the project listing page, click the Configure in the drop-down menu next to the project name. If you are creating a new project, follow the next steps:

1. Click on New Item

2. Enter your project name, choose Freestyle Project and click OK

3. In the Build section add Probely scan step.

We assume you have configured the other project options properly, such as checking out from your SCM, building the code and deploying it.

In just added ProbelySecurity Scanner section:

1. Add the Target Id, as defined in the Generating an API key step.
2. Select the right credentials, which were configured in Configuring credentials. If the connection to Probely's API is working correctly, and the credentials are valid, you should see the message "Credentials verified successfully".
3. When all steps are properly configured, click on Save

It is done. The next time the build job for this project runs, Probely will test the security of the configured target and will send you an email with the scan results in the end.

Using the plugin in a Pipeline project

Pipeline projects are the most flexible and powerful way of creating CI/CD pipelines with Jenkins.

The projects need a configuration file, a Jenkinsfile. The one in our example uses the more modern declarative syntax, instead of the imperative one.

1. Click on New Item

2. Enter your project name, choose Pipeline Project and click OK

3. Create a Jenkinsfile

pipeline {
    agent {
        docker {
            image 'maven:3-alpine'
    stages {
        stage('Unit tests') {
            steps {
                sh './gradlew check'
        stage('Scan with Probely') {
            steps {
                probelyScan targetId: '9nl6yy0TWWKv', credentialsId: 'probely-test-site'

As with the Freestyle project, the security tests are executed after the functional tests, in this case after the Unit tests stage, to ensure the application is working properly.

4. Configure Jenkins to use the Jenkins file on your repository

If your Jenkinsfile is stored in a repository that was already configured here (Definition Pipeline script from SCM) you only need to commit the updated file to the repository

Hit Save. Your pipeline has now a stage that scans your target for vulnerabilities.

You have some options on how Probely scans your target, at the target settings page: you can choose different scanning profiles, add a login URL and credentials to scan behind login pages, add custom headers and even enable automatic synchronisation with your project at Jira, just to name a few.
