CRYPTOcell is a breakthrough, ultra-small encryption solution. The CRYPTOcell is our most popular security item for protecting communications. It is currently used by military, corporations and individuals in over 30 countries. The CRYPTOcel only weights 11 grams and is small enough to fit inside a shirt pocket. The CRYPTOcell effectively prevents eavesdropping using AES 256 bit encryption for end-to-end communications.
Several security threats plague wireless communicatons including "man-in-the-middle" attacks (MIM), high-tech frequency scanners, lack of dual authenticity between handset & base station, and lack of encryption through the fixed public networks which most calls are routed. One of the best ways to protect sensative information against eavesdroppers is with the use of high-quality encryption devices offered by Global Teck Worldwide.

CRYPTOcell™ provides security to mobile phone users who can ill-afford to have their privacy, trade secrets nor intellectual property compromised. Unlike other existing GSM solutions which require you to purchase a dedicated and expensive cellular handset, CRYPTOcell™ is a ultra-smal, plug-n-play, accessory compatible with over 20 popular Ericsson T-Series GSM handsets. Just plug it into the handset and enjoy end-to-end military-strength security at excellenct voice quality! The encryption procedures are completely transparent and no user-intervention is required to start using powerful cell phone security

Users that require large deployment of secure wireless phones may want to consider the use of the Private Trunk™ (Secure Switch). The secure switch provides users many features that enhance interoperability, auditing and administrative funcitions that are normally not possibly with the CRYPTOcell alone. Additional details on the Private Trunk are provided below.


A) CRYPTOcell module only

B) CRYPTOcell with mobile phone bundle

1) GSM service.
2) Enabled data services- Circuit Switched Data (CSD). Unit will operate on both regular circuit switched data (CSD) and high-speed circuit switched data (HSCSD). Other terms used for data services include: Mobile Originate (MO) to Mobile Transmit (MT), or Asynchronous Data.

NOTES: Each country handles provisioning of data services differently. Check with your local GSM provider for service details. Some providers may provide a separate data number to transmit & receive data. Normally if your GSM provider can provide data services to laptop modems your CRYPTOcell should function with your GSM provider. The CRYPTOcell is the only unit in the world that will operate in transparent and non-transparent mode. Thus, providing you greater flexibility when roaming on different GSM networks. Typical delivery of CRYPTOcell is between 7-10 business days depending on location.

CRYPTOcell™ currently supports T-Series Ericsson GSM phones. The CRYPTOcell-300 is approved by the U.S. Commerce Department for export. For information on country-by-country GSM providers, GSM coverage maps and local data services go to the GSM World Website.




The development of CRYPTOcell™ continues to extend the world-class security products based on the SNAP (Secure Network Access Platform) architecture. Unlike the standard CRYPTOcell unit which features the tiny external encryption unit, our PDA has NO EXTERNAL DEVICES ATTACHED TO IT. Instead, the PDA features a built-in proprietary encryption software application for converged devices securing both voice and chat sessions from PDA phones running on a Pocket PC based system. Why take chances with your proprietary information? The CRYPTOcell encryption is based on government security standards established for AES algorithms.


Software based downloadable platform
Compatible with off-the-shelf PDA phones with Pocket PC
User friendly setup
Commercially exportable
FIPs compliant AES encryption
Communicates with CRYPTOcell-300 and SnapTrunk/PrivateTrunk
Snapsoft enabled devices are networkable for enterprise clients

Our CRYPTOfone unit is a small, lightweight, plug & play unit that secures voice, conference and fax communications. Carriers do not offer any security assurances on their public networks. Don't take any chances with your communications. CRYPTOfone is a POTS interface connected at the customer’s premises. Designed to protect your Land Lines at home or office, it quickly and easily connects between your telephone and the wall jack. When used in multi-point mode you can travel to hotels, foreign countries and other offices to make and recieve secure calls from any number in the world. For ISDN compatible unit, please ask for PT 200.


CRYPTOfone Enterprise Private Trunk™
(Network Based Multi-line Encryptor)

If you need to communicate securely between our CRYPTOcell and CRYPTOfone units, you will need our CRYPTOfone™ Enterprise Private Trunk™ system. Organizations with users in multiple locations can deploy Private Trunk™ - a secure communications rack-mounted wireline and cellular multi-line encryption gateway. The secure gateway adds point-to-multipoint calling capabilities to the CRYPTOcell™ along with additional security and administrative functions. The secure multi-line gateway can encrypt all corporate communications including fax, conferencing, cellular, wireline transmissions while secure all local loop communications. Effectively protecting the most vulnerable links against industrial espionage.

All secured calls are routed through the Private Trunk™ which acts as a gateway to and from service suppliers’ networks. Private Trunk™ encrypts and decrypts all voice, fax and data communications. The secure trunk is an open CTI system built to support telecommunication standards. The secure trunk allows the multi-point interface between secure wireless and land-line calls.

Private Trunk™ solution is focused on providing the latest in protections for information sharing amongst peers, suppliers, alliance partners and financial institutions. It provides enterprises with a cost-effective tool with a wealth of uniquely flexible security features, such as authentication (PKI), access control, dialing restrictions, VPN encryption, call destination encryption and point to any point secured communication, for voice, fax and data sessions. This solution can be deployed transparently over mobile and fixed networks.

The elements support in and between fixed networks through POTS/ISDN access, E1/T1 digital trunks and GSM networks. Private Trunk™ also incorporates unique peer-to-peer security. Built-in security features allows users to secure internal and external calls over public networks. Each secure trunk can provide various additional features including PBX firewall security, remote-dialing protections, call detail reports (CDR), central control of all registered units (CRYPTOfone, CRYPTOcell & Trunks) and service restriction capabilities. Each secure trunk can effectively support up to 1000 users.

If you are one of the countless people who have been waiting for a sophisticated, yet easy to use telephone scrambler your wait is over. Our new SECURE-CELL scrambling system provides the user with an high level of communication security over BOTH CELLULAR and LAND-LINE telephones. The Secure-Cell quickly and easily attaches onto most cellular or land line telephone handsets. With a Sec-Cell unit on each end of the conversation, all communications between the two units will be effectively protected against any and all types of eavesdropping. Scrambling is the most effective way to protect your sensitive communications. This tactical device will protect your conversation from various methods of eavesdropping from wire taps or electronic bugs. The unit is totally portable and can be used around the world on most telephones. Just how good are these units you ask? The Secure-Cell uses a digital encryption algorithm based on DSA that is applied to the user code in order to create secure communication. By programming a code up to sixteen digits, an algorithm is created that rolls the scrambling code up to 65536 times. This provides over seventeen hours of continued use before the pattern repeats. The Secure-Cell Phone Scrambler comes with an interconnect cable that will connect with Motorola, Samsung, LG and other models of cellular telephones that have a 2.5mm headset jack. Adapters are available to attach the cable to other models of cellular phones. A cable is also available to connect the Secure-Cell to a conventional Land-line telephone.

No other product on the market offers you protects both your land-line and your cellular telephone in one unit! Our units are sleek, compact, and work with virtually all cellular and land-line telephones.
