Use-Case Summaries

Share this post

1. High-Security Subnet Access

  • Just-in-time orchestration of firewall rules to grant temporary access (e.g., 60 minutes) to critical internal subnets.
  • Systems remain inaccessible until an operator logs in, removing standing exposure.
  • Prevents lateral movement and zero-day exploitation in OT/ICS or other sensitive networks by making them invisible outside authenticated sessions.
  • Ingress or Egress can be managed, allowing you to control external or internal network flows, third-party access or outbound telemetry/connect-back third-parties.

2. Remove VPN Attack Surface & Enforce MFA

  • Orchestrates existing firewalls to eliminate exposed VPN endpoints while tying access to IdP/MFA.
  • Removes Internet-facing VPN exposure without re-architecture or client software.
  • Stops credential-stuffing, brute-force, and VPN appliance zero-days; improves compliance by uplifting all accounts to MFA.

3. Third-Party Access to Restricted Webapps

  • Dynamic IP allowlisting tied to Knocknoc login for sensitive cloud-hosted applications.
  • Eliminates broad Internet exposure while still supporting unmanaged or mobile devices.
  • Enables partners and contractors to access critical apps securely without VPN clients, balancing usability and risk.

4. Ephemeral Outbound Internet Access for Patching

  • Time-bound outbound firewall exceptions orchestrated via Knocknoc.
  • Admins can temporarily open Internet access for patching, automatically closing after the session.
  • Maintains a strict default-deny posture while enabling operational maintenance – no more “sneaker-net” patching.

5. SSH Attack Surface in Distributed Environments

  • Host-based firewall orchestration to render SSH ports invisible until authenticated.
  • Zero added hops, latency, or routing changes; SSH access bound to identity.
  • Eliminates pre-auth attack surface, closes compliance gaps by enforcing MFA on SSH, and scales seamlessly across distributed teams.

6. File Transfer Gateway & Ad-Hoc Uploads

  • Orchestrates firewalls for just-in-time access to FTP/SFTP/file-transfer platforms.
  • Keeps file-transfer services invisible to the Internet except during authenticated uploads.
  • Prevents exploitation of unpatched file-transfer platforms while still supporting unmanaged endpoints like cameras and contractor laptops.

7. Trusted Partner Access to Web Applications

  • Knocknoc integrates with IdP to secure custom or internal web applications with pre-authentication access control.
  • Removes Internet exposure without changing the access flow for trusted business partners.
  • Protects highly confidential data exchange (e.g., finance) while delivering a seamless, installation-free experience.

8. HPC, SFTP & Coexisting with ZTNA

  • Just-in-time IP/port orchestration to support high-bandwidth, direct data transfers.
  • Provides secure SFTP access without introducing routing changes or agent installations.
  • Complements existing ZTNA deployments by securing file-transfer workflows at scale without breaking performance.
