FAQ

What makes Ambit Client different from traditional VPNs?

Ambit Client is the only VPN that exclusively uses CNSA 2.0 algorithms across all four key components (Authentication, Key Exchange, Bulk Encryption, Hashing). This provides mathematically proven protection against quantum computing attacks, unlike traditional VPNs that may be vulnerable to future decryption.

Is Ambit Client available for individual users?

Currently, Ambit Client is available for enterprise deployment. Organizations interested in its quantum-secure capabilities can contact sales@ambit.inc for more information.

What is HNDL and how does Ambit Client protect against it?

HNDL (Harvest Now, Decrypt Later) is a threat where bad actors harvest data now to decrypt it later with quantum computers. Ambit Client's exclusive use of CNSA 2.0 algorithms, including ML-KEM 1024 cryptography, is mathematically proven to resist these attacks.

How easy is Ambit Client to use?

Ambit Client is designed to be as easy to use, or even easier, than conventional VPNs. It utilizes a fast, innovative networking technology called Vector Packet Processing (VPP).

What are the risks of using traditional VPNs against quantum threats?

Traditional VPNs that rely on Diffie-Hellman Key Exchange, hybrid cryptography, or elliptic-curve cryptography are exposed to HNDL attacks. This means sensitive data could be decrypted once quantum computers become powerful enough, potentially as early as 2030.

What devices does Ambit Client support?

Ambit Client is supported on iPhone, iPad, and iPod devices.

How often is Ambit Client updated?

The latest version of Ambit Client is 1.15.0, and it was last updated on February 27, 2026. This indicates a commitment to regular updates and maintenance.

Does Ambit Client have ads?

Ambit Client does not contain advertisements.
