Chapter A9:

Managing Work Devices

Everyone receives a new Mac when they join 37signals. We centrally manage and secure these devices with Kandji which reduces our exposure to security incidents. Kandji applies a standard configuration to every device (e.g. enable disk encryption, firewall, password rules), it installs essential apps (e.g. EncryptMe), and it will ensure the apps have the latest security updates applied. Kandji also allows us to remotely wipe devices should they be lost, or when an employee leaves the company.

This doesn’t mean you are being monitored or tracked! Kandji is a configuration management system, not a panopticon.

Access to code and secrets

Knowing our devices are safe and secure allows us to entrust our work computers with access to sensitive systems like Queenbee, Dash, our internal VPN and remote servers. This means installing the VPN, checking out 37signals code, storing secrets, and connecting to the 37signals 1Password account must only be done on a managed work device, not a personal device.

Personal data on a work device

It’s best to avoid mixing business with pleasure, so you must separate personal and work computer usage. Firstly, 37signals should not have access to your family photos, email, messages and personal files. Secondly, one high-profile hack after another is due to commingling personal and work use on a laptop that has access to sensitive systems. There are also hazards of exposing work to your personal data:

Ultimately, work computers are for work, so please make sure personal data and personal computer usage is kept to your own device.

Mobile devices, Windows and Linux

Devices running Android, iOS/iPadOS, Windows or Linux are currently unmanaged. It’s fine to install our BC4 and HEY apps on these devices to access work projects and email, but since they’re unmanaged – and therefore ‘untrusted’ – it’s not fine to store 37signals code or secrets on them. If you’re coding or accessing secure systems, you should be doing so on a Kandji-managed Mac.


There are many questions that arise from IT policies such as this, so we’ve produced an FAQ in BC4 to help answer them.
