Knocknoc reduces the attack surface of existing infrastructure by orchestrating network-level access controls and linking them to an identity platform. Ports remain closed, and services stay invisible until users log in centrally. Knocknoc handles the rest.

What to expect from an ideal product

1. Knocknoc keeps your current security stack in place while adding an extra layer that hides services from attackers until legitimate users authenticate
2. All network ports stay closed by default, making your infrastructure invisible to port scanners and automated attacks that constantly probe for open services
3. Users authenticate through a single identity platform first, then Knocknoc automatically opens only the specific network paths they need for their role
4. The system works behind the scenes to manage network access without requiring you to reconfigure or replace your existing firewalls, VPNs, or security tools
5. Attack surface shrinks dramatically because services become unreachable to unauthorized users, even if they know the IP addresses or have network access
