Two clocks are running at once. Adversaries are recording encrypted traffic today to decrypt it later, once quantum computers mature. The same adversaries exploit implicit trust inside perimeter networks to move laterally between systems that should never have been able to reach each other.
GABRL answers both. Direct peer-to-peer Layer 3 IPSec/IKEv2 tunnels protected by post-quantum cryptography, authorized and monitored by a control plane that never touches data traffic. Ephemeral keys exist only in memory during a session, so there is nothing to harvest now and decrypt later. In production today.
Key Capabilities
Single Binary, Single Deployment
One binary serves as both client and control plane. Bare metal, virtual machine, or container. Same binary, same crypto, same Zero Trust enforcement. Operators install one file.
Post-Quantum Cryptography
Every session uses ML-KEM-1024 (FIPS 203) and ML-DSA-87 (FIPS 204) with hybrid key exchange and AES-256-GCM. The mandated algorithms, running in production today.
Direct Peer-to-Peer Tunnels
Endpoints connect directly to authorized peers. No gateways, no middlemen, no traffic concentration point. Encryption happens once at the source and once at the destination.
Separated Control and Data Planes
The control plane authorizes connections, monitors health, pushes policy, and signs certificates. It never sees or routes application traffic, even if compromised.
Built for the Edge
Endpoints authenticate once and continue communicating with authorized peers when the control plane is unreachable. Satellite, cellular, and disconnected environments keep Zero Trust enforcement.
Federal Compliance Built-In
Aligns with NIST SP 800-207, NSM-10, OMB M-22-09, and FIPS 203/204. Operational ahead of the CNSA 2.0 default for new national security systems in 2027.
What Does GABRL Secure?
How GABRL Works
- Authentication and Authorization. Each endpoint proves its identity to the control plane with a post-quantum signed certificate. Policy decides which peers it may reach.
- Ephemeral Certificate Exchange. Session-unique certificates are generated for this session only. There is no master key to steal and no certificate store to raid.
- Direct Tunnel Creation. A peer-to-peer Layer 3 IPSec/IKEv2 tunnel with AES-256-GCM encryption is established between endpoints. No gateway in the middle.
- Secure Communication. All traffic is encrypted at Layer 3, beneath applications, protecting any application's data without code changes.
- Clean Termination. When the session ends, keys and certificates are discarded. They existed only in memory, leaving no persistent attack surface and nothing recorded today that becomes readable later.
Technical Advantages
Layer 3 Security. GABRL works at the Internet Protocol layer, beneath the applications it protects. Most security solutions sit at the application layer and ride above the transport.
Quantum-Resistant Certificates. Session-unique ephemeral certificates signed with ML-DSA-87 protect previous, current, and future sessions against replay and harvest-now-decrypt-later attacks.
Direct Endpoint Connections. Peer-to-peer tunnels eliminate hairpinning and remove the concentration points adversaries target.
Single Packet Authorization. GABRL endpoints respond to nothing until cryptographic authentication succeeds. To scanners and reconnaissance tools, protected endpoints simply do not exist.
Contained Blast Radius. A compromised endpoint reaches only the connections policy authorized it to make, and nothing else.
One Tunnel Per Authorized Pair
The five steps above produce the connection below. Each authorized pair of endpoints holds its own post-quantum tunnel, keyed in memory for the life of the session.
Built for Your Mission
Federal
Civil agencies face the 2035 post-quantum migration, OMB Zero Trust pillars, and CISA's January 2026 guidance to buy PQC-capable products now. GABRL runs the mandated algorithms today on existing infrastructure.
Defense
The DoD Zero Trust target, the November 2025 PQC directive, and CNSA 2.0 converge on the same timeline. GABRL holds Zero Trust at the tactical edge, under partition, and in contested networks.
Commercial
Patient records, intellectual property, payment traffic, and OT networks all carry data whose confidentiality must outlive today's cryptography. GABRL removes the keys adversaries are harvesting.
From the Field
Securing the Skies
How GABRL protects air traffic control communications from quantum threats. Safety-critical voice and data links get post-quantum protection without changes to the systems controllers rely on.
Diplomatic Security Reimagined
Zero Trust for embassy communications. Posts operating on infrastructure they do not control keep sovereign, end-to-end encrypted channels home, with nothing for the host network to find.
Beyond Line of Sight
As forces integrate AI-enabled systems and autonomous platforms, GABRL provides the trusted communications foundation those capabilities require, from RF links to remote operations.
Retire the Gateway
Perimeter architectures concentrate every session on hardware that adversaries treat as a high-value target. GABRL replaces the concentration point with a federated mesh of control planes that authorize direct tunnels and never carry them.
How GABRL Compares
GABRL provides capabilities that set it apart from traditional VPNs and other Zero Trust solutions. Most of the field converges traffic on an intermediary and secures access at the application layer.
