Secfense Ghost is a network cloaking tool that removes VPN concentrators and remote access gateways from public Internet visibility. Rather than hardening or patching exposed services, it hides them entirely by default and dynamically exposes them only to authenticated users on a per-session basis. How it works: - A user authenticates via a predefined channel (e.g., email domain verification or MFA) - Upon successful authentication, the user's IP is temporarily added to an allowlist - The VPN becomes reachable only from that specific IP address - All other parties — including scanners, bots, and attackers — see no open ports or public-facing services - When the session ends or the user changes networks, access is immediately revoked Key characteristics: - Requires no replacement or reconfiguration of existing VPN infrastructure - Provides just-in-time access control with no permanent Internet-facing endpoints - Reduces external attack surface to zero by default - Provides resilience against zero-day exploits targeting VPN software, since the service is unreachable before authentication - Aligns with Zero Trust principles by combining verified identity with session and location monitoring - Supports compliance frameworks including DORA, NIS2, and PSD2 - Designed to be transparent to end users — no new client apps or agents required
