If you had a $10000 budget to implement a security tool at your company, what would you choose?

We already have antivirus, firewalls, backup software, and physical security (cameras, an RFID door locking system) at a mid-sized company. What would you choose to implement? Not enough money for any SIEM tools as far as I know (definitely not enough to pay an analyst to monitor the activity) and I don’t want to be too redundant with our current setup.
