We created Scorecard to help open source maintainers improve their security best practices and to help open source consumers judge whether their dependencies are safe.
Scorecard is an automated tool that assesses a number of important heuristics ("checks") associated with software security and assigns each check a score of 0-10. You can use these scores to understand specific areas to improve in order to strengthen the security posture of your project. You can also assess the risks that dependencies introduce, and make informed decisions about accepting these risks, evaluating alternative solutions, or working with the maintainers to make improvements.
The inspiration for Scorecard’s logo: "You passed! All D's ... and an A!"
Project GoalsAutomate analysis and trust decisions on the security posture of open source projects.
Use this data to proactively improve the security posture of the critical projects the world depends on.
Scorecard has been run on thousands of projects to monitor and track security metrics. Prominent projects that use Scorecard include:
View a Project's ScoreTo see scores for projects regularly scanned by Scorecard, navigate to the webviewer, replacing the placeholder text with the platform, user/org, and repository name: https://securityscorecards.dev/viewer/?uri=<github_or_gitlab>.com/<user_name_or_org>/<repository_name>.
For example:
To view scores for projects not included in the webviewer, use the Scorecard CLI.
Public DataWe run a weekly Scorecard scan of the 1 million most critical open source projects judged by their direct dependencies and publish the results in a BigQuery public dataset.
This data is available in the public BigQuery dataset openssf:scorecardcron.scorecard-v2
. The latest results are available in the BigQuery view openssf:scorecardcron.scorecard-v2_latest
.
You can query the data using BigQuery Explorer by navigating to Add Data > Star a project by name > 'openssf'. For example, you may be interested in how a project's score has changed over time:
SELECT date, score FROM `openssf.scorecardcron.scorecard-v2` WHERE repo.name="github.com/ossf/scorecard" ORDER BY date ASC
You can extract the latest results to Google Cloud storage in JSON format using the bq
tool:
# Get the latest PARTITION_ID
bq query --nouse_legacy_sql 'SELECT partition_id FROM
openssf.scorecardcron.INFORMATION_SCHEMA.PARTITIONS WHERE table_name="scorecard-v2"
AND partition_id!="__NULL__" ORDER BY partition_id DESC
LIMIT 1'
# Extract to GCS
bq extract --destination_format=NEWLINE_DELIMITED_JSON
'openssf:scorecardcron.scorecard-v2$<partition_id>' gs://bucket-name/filename-*.json
The list of projects that are checked is available in the cron/internal/data/projects.csv
file in this repository. If you would like us to track more, please feel free to send a Pull Request with others. Currently, this list is derived from projects hosted on GitHub ONLY. We do plan to expand them in near future to account for projects hosted on other source control systems.
The easiest way to use Scorecard on GitHub projects you own is with the Scorecard GitHub Action. The Action runs on any repository change and issues alerts that maintainers can view in the repository’s Security tab. For more information, see the Scorecard GitHub Action installation instructions.
Scorecard REST APITo query pre-calculated scores of OSS projects, use the REST API.
To enable your project to be available on the REST API, set publish_results: true
in the Scorecard GitHub Action setting.
Data provided by the REST API is licensed under the CDLA Permissive 2.0.
Scorecard BadgesEnabling publish_results: true
in Scorecard GitHub Actions also allows maintainers to display a Scorecard badge on their repository to show off their hard work. This badge also auto-updates for every change made to the repository. See more details on this OSSF blogpost.
To include a badge on your project's repository, simply add the following markdown to your README:
[](https://securityscorecards.dev/viewer/?uri=github.com/{owner}/{repo})
Scorecard Command Line Interface
To run a Scorecard scan on projects you do not own, use the command line interface installation option.
PrerequisitesPlatforms: Currently, Scorecard supports OSX and Linux platforms. If you are using a Windows OS you may experience issues. Contributions towards supporting Windows are welcome.
Language: You must have GoLang installed to run Scorecard (https://golang.org/doc/install)
InstallationDocker
scorecard
is available as a Docker container:
docker pull gcr.io/openssf/scorecard:stable
To use a specific scorecard version (e.g., v3.2.1), run:
docker pull gcr.io/openssf/scorecard:v3.2.1
Standalone
To install Scorecard as a standalone:
Visit our latest release page and download the correct zip file for your operating system.
Add the binary to your GOPATH/bin
directory (use go env GOPATH
to identify your directory if necessary).
Verifying SLSA provenance for downloaded releases
We generate SLSA3 signatures using the OpenSSF's slsa-framework/slsa-github-generator during the release process. To verify a release binary:
attestation.intoto.jsonl
from the GitHub releases page.slsa-verifier -artifact-path <the-zip> -provenance attestation.intoto.jsonl -source github.com/ossf/scorecard -tag <the-tag>
Using package managers
Package Manager Supported Distribution Command Nix NixOSnix-shell -p nixpkgs.scorecard
AUR helper Arch Linux Use your AUR helper to install scorecard
Homebrew macOS or Linux brew install scorecard
Authentication
GitHub imposes api rate limits on unauthenticated requests. To avoid these limits, you must authenticate your requests before running Scorecard. There are two ways to authenticate your requests: either create a GitHub personal access token, or create a GitHub App Installation.
public_repo
scope. Set the token in an environment variable called GITHUB_AUTH_TOKEN
, GITHUB_TOKEN
, GH_AUTH_TOKEN
or GH_TOKEN
using the commands below according to your platform.# For posix platforms, e.g. linux, mac:
export GITHUB_AUTH_TOKEN=<your access token>
# Multiple tokens can be provided separated by comma to be utilized
# in a round robin fashion.
export GITHUB_AUTH_TOKEN=<your access token1>,<your access token2>
# For windows:
set GITHUB_AUTH_TOKEN=<your access token>
set GITHUB_AUTH_TOKEN=<your access token1>,<your access token2>
OR

or export
) shown above for your platform.GITHUB_APP_KEY_PATH=<path to the key file on disk>
GITHUB_APP_INSTALLATION_ID=<installation id>
GITHUB_APP_ID=<app id>
These variables can be obtained from the GitHub developer settings page.
Basic UsageUsing repository URL
Scorecard can run using just one argument, the URL of the target repo:
$ scorecard --repo=github.com/ossf-tests/scorecard-check-branch-protection-e2e

Using a GitLab Repository
To run Scorecard on a GitLab repository, you must create a GitLab Access Token with the following permissions:
read_api
read_user
read_repository
You can run Scorecard on a GitLab repository by setting the GITLAB_AUTH_TOKEN
environment variable:
export GITLAB_AUTH_TOKEN=glpat-xxxx
scorecard --repo gitlab.com/<org>/<project>/<subproject>
For an example of using Scorecard in GitLab CI/CD, see here.
Using GitHub Enterprise Server (GHES) based Repository
To use a GitHub Enterprise host github.corp.com
, use the GH_HOST
environment variable.
# Set the GitHub Enterprise host without https prefix or slash with relevant authentication token
export GH_HOST=github.corp.com
export GITHUB_AUTH_TOKEN=token
scorecard --repo=github.corp.com/org/repo
# OR without github host url
scorecard --repo=org/repo
Using a Package manager
For projects in the --npm
, --pypi
, --rubygems
, or --nuget
ecosystems, you have the option to run Scorecard using a package manager. Provide the package name to run the checks on the corresponding GitHub source code.
For example, --npm=angular
.
Running specific checks
To run only specific check(s), add the --checks
argument with a list of check names.
For example, --checks=CI-Tests,Code-Review
.
Formatting Results
The currently supported formats are default
(text) and json
.
These may be specified with the --format
flag. For example, --format=json
.
The following checks are all run against the target project by default:

Other Important Recommendations Two-factor Authentication (2FA)Two-factor Authentication (2FA) adds an extra layer of security when logging into websites or apps. 2FA protects your account if your password is compromised by requiring a second form of authentication, such as codes sent via SMS or authentication app, or touching a physical security key.
We strongly recommend that you enable 2FA on GitHub and any important account where it is available. 2FA is not a Scorecard check because GitHub does not make that data about user accounts public. Arguably, this data should always remain private, since accounts without 2FA are so vulnerable to attack.
Though it is not an official check, we urge all project maintainers to enable 2FA to protect their projects from compromise.
Enabling 2FAFor users
Follow the steps described at Configuring two-factor authentication
If possible, use either:
As a last option, use SMS. Beware: 2FA using SMS is vulnerable to SIM swap attack.
For an organization
Scoring Aggregate ScoreEach individual check returns a score of 0 to 10, with 10 representing the best possible score. Scorecard also produces an aggregate score, which is a weight-based average of the individual checks weighted by risk.
See the list of current Scorecard checks for each check's risk level.
