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.
