K-Firewall
The native firewall, finally managed from a console
K-Firewall builds on the firewall built into Windows and macOS: it applies profiles by network type, closes dangerous ports and isolates a compromised computer in one click.
The problem
The firewall built into the system is solid, but rarely configured consistently. An exposed file share or remote desktop is enough to open the door.
What the module does
Profiles by network
Home, office, public network: rules suited to each situation.
Risky ports closed
File sharing and remote desktop blocked from the Internet by default.
One-click isolation
A compromised computer is cut off from the network, except from the console, while it is analysed.
No extra driver
The module manages the system's native mechanisms, without adding kernel code.
How it works
Policy
You choose the profiles in the console.
Enforcement
The agent translates the policy into native firewall rules.
Control
Any configuration drift is flagged.
What you should know
- The module is in development; network isolation is the first feature built.
- macOS is supported after Windows.
