StealthComms

StealthComms

Introspective Networks

StealthComms is the first truly confidential Internet based messaging system. Protect your text communications with team members, clients, patients, and partners. Ideal for banking, HR, healthcare, investor, legal, government, and other business communications, StealthComms' patented Moving Target Defense/Streaming Encryption technology keeps your communications safe from data interception and decryption.

StealthComms is FREE for a limited time.

Key Features:
- Constantly changing transmission paths create a Moving Target Defense (MTD) that prevents individuals/entities from tapping into conversations
- Device-to-device data encryption utilizes One Time Pad (OTP) encryption methodology, proven mathematically to be uncrackable
- Conversations are not saved or stored on any devices or servers, eliminating the possibility of future discovery
- Encrypted data and streaming keys are transmitted across separate paths
- Double encrypted messages - once for the system and again for client-to-client communications
- Recipient acceptance required before communications can start, ensuring both parties are in suitable locations
- Professional, no nonsense interface provides what you need
- Technology Readiness Level 7 approved by the USAF
- Globally available and usable

StealthComms utilizes Introspective Networks’ patented STOP technology. Using real, symmetric encryption via a One Time Pad, data is sent between devices in a way that is proven mathematically uncrackable. Moreover, the data is not simply encrypted, it is literally hidden in the network as it’s moved around in a way that, when combined with uncrackable encryption, makes a man in the middle attack practically impossible. Messages are actually double encrypted – once for the system and again for client-to-client communications. This means your communication is completely secret between two users.

StealthComms does not save data. The app provides a live one-to-one session that does not record or store data on devices or servers, thus removing the concern that information will be left behind for future discovery. Even if either device is cracked, previous conversations no longer exist. The app will not allow conversations to continue if placed in the background, a state when the device limits the ability to monitor for intrusion.

StealthComms has been Technology Readiness Level 7 approved by the USAF and is the only system that has vetted all aspects of confidential communications.

StealthComms is made possible by patented STOP technology (patent US8995652). This is the first and only known technology to allow a real One Time Pad to be used across a network securely.

Message Confidentially. Message Confidently.

Internet communications just became secure...

Encrypt SMS - Send Secret Text Messages

Encrypt SMS - Send Secret Text Messages

Sherwin Sowy

Ever wanted to send a text message or SMS that only you and your recipient can understand? Need to send confidential information via SMS, safe from anyone's prying eyes?

Encrypt SMS is a tool that allows you to encrypt messages that you send out with a password, and only those that have the same password can successfully decrypt and read the messages. (Recipient must have the same application on their iPhone.)

Encrypt SMS uses AES-256 encryption, a military-grade encryption composed of a 256 bit key to ensure that it will not be easily broken. The US government itself uses AES encryption to secure classified information! You too can have access to this high level of security with Encrypt SMS.
