End-to-End Encryption with Post-Quantum Protection for Secure Voice, Video, Messaging, and File Transfers Protecting Sensitive to Highly Classified
Government Communications Worldwide.

Secure Instant Messaging

Need to send a large file (500MB+) securely? No Problem.

CSG delivers military-grade encryption for private messaging, facilitating the seamless and secure exchange of files and ideas.

Share photos, videos, voice notes and files effortlessly. Each message and file you send is safeguarded by a unique encryption key, providing unparalleled end-to-end security.

CSG enhances your collaborative efforts by allowing the creation of group chats for private messaging and file sharing directly within the app. These features boost productivity and foster secure, efficient communication within your enterprise.

Secure Voice and Video Calls

Calls are safeguarded with end-to-end encryption and signal obfuscation, providing the highest level of security through your mobile device's data connection.

But it's not just about securing your calls; it's about enhancing your communication experience. CSG''s cutting-edge phone call encryption codecs ensure high-definition call quality, optimizing data and battery usage even across the most austere, low-bandwidth, mobile / wireless networks.

CSG supports secure calling over an extensive range of IP-based networks, including Wi-Fi, 5G, 4G/LTE, 3G/HSDPA, and satellite networks. Mutual authentication of all call participants eliminates any potential risks associated with Caller ID spoofing and Man in The Middle (MITM) attacks.

Secure Conference Calls

A conference bridge can be established instantly by creating a group of contacts and hitting the call button. With only mutually authenticated, authorized users, CSG conference calls eliminate the need for participant PINs and passwords.

Work Anywhere, on Any Device

CSG can be downloaded instantly for immediate use with no additional hardware dependencies.

End-to-End Encryption

CSG uses double-layer encryption in an end-to-end configuration, with a new key for every call and message. The system is modular and adheres to best practice cryptographic standards/protocols, powered by a robust crypto core. With CSG, data is secured end-to-end using advanced Elliptic Curve and Symmetric-Key Cryptography.

For post-quantum protection, the underlying cryptography is overlaid with state-of-the-art Post-Quantum Cryptography algorithms for voice, video, messaging, and file transfers.

International Security Standards
CSG is designed to meet the highest international security standards and is trusted by governments worldwide for protecting their most sensitive communications.
