Sensitive information

Here’s what you need to know about sensitive information at 18F.

What is considered sensitive?

To learn what information we consider sensitive, see our Open Source Policy practices guide.


18F offers a few different tools for sharing sensitive information. As you learned in your Security Awareness and Privacy training in GSA Online University (OLU), only share sensitive information with the people who absolutely need it and are authorized to see it.

Git Seekret

To prevent committing sensitive data to your Git repository, install git-seekrets and pre-commit hooks. Please install the git-seekrets binary, which prevents the committing of certain sensitive information to your Git repository. Examples include environment variables and private configuration data.

Refer to the official installation guide for Git Seekrets. You can use the installed binary with either the command-line or with the GitHub Desktop interface.

Git Seekret does verification of the current files that will be committed to your repository using the git precommit-hook. This runs for every commit and will not allow you to commit your changes if any secrets are found.

To contribute regular-expressions to match new rules, see the documentation.


You can use Fugacious for short-term secure messaging. Fugacious is most useful for sending small bits of text once, such as passwords or API keys. Set the lowest acceptable “self-destruct” settings for the number of views and hours available that you need (maximum 48 hours). You can share Fugacious links over TTS Slack, but don’t put sensitive information in Slack directly.

If you’re on the team, see this additional policy for sharing sensitive information.

Google Drive

You can use GSA Google Drive to share sensitive files, spreadsheets, and documents. This includes personally identifiable information (PII) of either federal staff or the public, but it does not include classified information of any kind. If you’re handling PII, be absolutely sure you are only sharing Drive files with GSA staff and that those staff members have a direct need for the information.


You can use OMB MAX to share sensitive files (in appropriate “workspaces” within MAX). We typically use MAX for working with partners who don’t have access to — or who don’t feel comfortable putting the information in — Google Drive. Some workspaces in MAX are available to private organizations (for example, cloud service providers in the FedRAMP workspaces) and many other government agencies. Be sure you know who you’re sharing with before posting.
