What would you recommend as a very robust firewall solution for small office

Hi,

We are looking for a wired firewall solution for our office.

High robustness is the most important requirement for our firewall solution.

There are features such as multiple VPN connections which are nice but not as important.

What would you recommend as a very good firewall solution for office with following requirements:

- Highly Robust solution
- For small office (less than 10 PCs)
- Secure remote connections to office PCs
- Secure Office 365 network connectivity
- Support our network internet speeds: last test got 37.7mb/s download, 38.4mb/s upload, 17ms latency

Thanks,
Robbie
