Firewall for 50 users: what you need and what it costs
For 50 people, plan on an internet line of about 100 Mbps and a firewall that can inspect at least 150 Mbps with all security features switched on. That is the "threat protection" figure in each brand's datasheet, not the bigger "firewall throughput" number.

Questions
How big a firewall do 50 users need?
Size on threat protection throughput, at least 150 Mbps for 50 users, with 50% headroom for busy hours. If you plan to inspect HTTPS traffic, choose the next size up.
Do I need a licence with the firewall?
Yes. Antivirus, intrusion prevention and web filtering need a yearly subscription. Ask sellers to quote the hardware with a 1-year and a 3-year bundle so you can compare.
Should I buy two firewalls?
If the internet must not go down, a second unit in high availability takes over within seconds. It doubles the hardware cost but usually not the licence cost for the standby unit.
