[kiselik]

Does the feature exist in the most recent commit?

changes currently available in fork: https://github.com/kiselik/googletest/tree/ossf PR will be raised a little bit later

Why do we need this feature?

I’d like to suggest adding the OpenSSF Scorecard badge to this repository’s README to improve transparency around security best practices.

The Scorecard project is an initiative from the Open Source Security Foundation (OpenSSF) that evaluates open-source repositories against a set of automated security checks (e.g., branch protection, dependencies, fuzzing, CI/CD usage, etc.).

Benefits

• Shows commitment to open-source security
• Increases trust with users and contributors
• Automatically updates with your project’s latest Scorecard rating

Describe the proposal.

the proposed changes are implemented via 2 steps:

• setting up gitHub workflow with weekly scheduled job
• publishing results as a badge which is available via README

Is the feature specific to an operating system, compiler, or build system version?
