Remote Desktop Setup for Small Team

I need a secure and reliable remote desktop solution for a small team of 1-5 users. The solution must support both Windows and macOS operating systems.

Key Requirements:
- Compatibility with Windows and macOS
- Secure and reliable connectivity
- Ability to support 1-5 concurrent users

Ideal Skills and Experience:
- Proven experience in setting up remote desktop solutions
- Strong knowledge of Windows and macOS systems
- Excellent understanding of remote desktop security protocols
- Good communication skills for providing clear setup instructions

Please note that the primary purpose for this remote desktop has not yet been determined. I am open to suggestions on how to best utilize this setup for our team's needs, whether it be for accessing work files, remote support or virtual collaboration.
