The Only Quantum-Secure VPN Your success relies on secure data, but quantum computing will break it wide open. You deserve to keep what you've earned; use Ambit Client to secure your success against quantum computing attacks. Ambit Client is available now for enterprise deployment. Organizations interested in protecting their data from current and quantum threats can contact sales@ambit.inc for more information. THE PROBLEM Quantum computing is rendering conventional security obsolete and it’s not just a problem when quantum computers arrive, it’s a problem now. Bad actors are harvesting your business data to decrypt later with a quantum computer (HNDL)... and when that happens, company executives could be held liable. You used to be able to protect data using a convention VPN, but quantum computing has changed that. Now you need a post-quantum VPN, and you need one that uses exclusively CNSA 2.0 algorithms. THE SOLUTION Everything you work so hard for is it risk. Only Ambit Client can protect your success because Ambit Client is the only VPN that uses exclusively CNSA 2.0 algorithms mathematically proven to protect against HNDL. Ambit Client is also as easy as or even easier to use than conventional VPNs. Ambit Client VPN makes use of a fast, innovative networking technology called Vector Packet Processing (VPP). THE QUANTUM SECURITY GAP Current VPN solutions leave organizations vulnerable by implementing quantum-resistant algorithms in only some of their cryptographic components. For true quantum resistance, all four key components must meet CNSA 2.0 standards: Authentication Key Exchange Bulk Encryption (AEAD) Hashing Ambit Client stands alone in using exclusively CNSA 2.0 algorithms across all four components, including the implementation of ML-KEM 1024 cryptography-mathematically proven to resist both conventional and quantum computer attacks. Organizations using traditional VPNs that rely on Diffie-Hellman Key Exchange, hybrid cryptography, or elliptic-curve cryptography remain exposed to HNDL attacks. These vulnerabilities could allow adversaries to decrypt sensitive data once quantum computers become capable enough—a milestone expected as early as 2030. “As I revealed in my Bloomberg documentary, The Massive Cyberattack You Never Heard About, the greatest cyber threats aren’t just coming—they’re already here. Quantum computing will soon shatter traditional encryption, leaving our most sensitive data exposed. That’s why investing in post-quantum solutions isn’t optional; it’s urgent. American Binary’s post-quantum VPN embodies the resilience, security, and innovation that define American Binary values—ensuring that our critical infrastructure remains protected against the next frontier of cyber warfare. The future belongs to those who secure it now.” — Jose Arrieta, former CIO of U.S Department of Health & Human Services (HHS) and CEO of Imagineer LLC. American Binary was also featured in Booz Allen Hamilton's "Top 10 Emerging Technology for DoD and National Security" 2024

Verdict
The clearest difference is in-app purchases: Ambit Client at none against StarBridge's 2. StarBridge's advantage is update cadence (every 9 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
