## GitHub Package Firewall Preview
GitHub opened its Package Firewall to GitHub Enterprise Cloud customers in a changelog entry dated October 20th and published October 21st.
## How Package Firewall Works
The firewall routes npm metadata requests and downloads through a policy layer before dependencies reach build hosts, developer workstations or coding agents.
## Preview Pricing Model
The preview is free; GitHub says it plans metered pricing when the service reaches general availability, without giving a date or numerical rates.
## Key takeaway

GitHub's free npm firewall preview routes packages through policy checks before they reach developer machines.
