Traceable and Secure Mobile Communication for Highly Regulated Industries



The CellTrust SecureLine™ Mobile Collaboration Suite - available as an enterprise level application for both Android and Apple iOS - offers secure mobile collaboration through SMS/messaging, voice and a Mobile Business Number to enhance workflows. The proliferation of enterprise business applications, coupled with the bring-your-own device (BYOD) wave, place heavy traceability, archiving and security demands on all mobile communication within highly regulated industries, such as financial services, healthcare and government.

The CellTrust SecureLine™ Mobile Collaboration Suite provides secure message and voice archiving, to support regulatory guidelines such as:

  • The Dodd-Frank Act
  • Gramm-Leach-Bliley Act (GLB)
  • Security and Exchange Commission (SEC) guidelines in the US
  • Financial Conduct Authority (FCA) and the Prudential Regulation Authority (PRA) in the UK
  • European Securities and Markets Authority (ESMA) among others

Flexible Deployment and Total Network Control

Engineered on the CellTrust Secure Mobile Information Management (SMIM) Platform and fully integrated to the CellTrust SecureSMS Gateway, CellTrust SecureLine requires a connection to a secure server, which can be deployed as SaaS or customer hosted (VM or appliance). All mobile communications (SMS/messaging and voice) provisioned by CellTrust SecureLine are time and date stamped, tracked, and logged to support compliance with regulatory agencies’ standards and guidelines.

The CellTrust SecureLine server and devices are managed through an interactive web-based portal which gives IT administrators the convenience and ease of having a centralized point of access and complete control of the network. IT administrators have the ability set security requirements with features for registration and multiple levels of authentication, also to remote wipe devices, control inactivity time-outs, and manage lifespan for messages residing on devices. Administrators also receive validated proof of delivery, opened/or deleted for application to device, operator to device, and device to device. Should the employee no longer be with the organization, or be out of the office, the administrator can redirect clients’ mobile communication to a new employee without impacting the client experience.

CellTrust SecureLine Features and Benefits:

Multi-factor authentication

CellTrust provides strong authentication of each users connection to the CellTrust Communication framework through a two part authentication process. Through authentication of both the device as well as the user, CellTrust is able to strongly protect the communications session with the CellTrust Server. This strongly authenticated session acts as a trust anchor to allow for secure communications between the server and the client.

Communication protected through up to 3 layers of end-to-end 256 bit AES encryption

Data at rest, on the device, on the server, or in-transit are fully encrypted with unique dynamic keys, providing the highest level of security to prevent mission critical information from getting into the wrong hands when both sender and receiver use the CellTrust SecureLine app.

Mobile Business Number
Enables traceability through a secondary phone number

Track and trace employee enterprise voice communication

CellTrust SecureLine was engineered to deliver an unrivaled dual persona approach for enterprise mobile users. Employees no longer need to carry multiple phones because one device provides the same functionality of two phones, one for personal use and the other for business use. The Mobile Business Number(MBN) is an exclusive feature of CellTrust SecureLine which assigns a second number for the device, using the existing SIM. Once activated, the MBN is completely autonomous from the phone’s actual number by having its own SMS and voice communication, logs, records and audit trails; thus preserving the duality. The MBN is designed to keep corporate and personal mobile communication separate.

In addition, the MBN is essential to organizations that require archiving and recording solutions for SMS and voice communication. It provides the same level of traceability for conversations among employees and external mobile communication with the ‘outside world’. With CellTrust SecureLine, all SMS messages and voice calls going to and from the MBN are tracked and traced, vital to eDiscovery and industry compliance. Owned by the organization, the MBN can be redirected as employees come and go.

  • Calls to and from the Mobile Business Number are time and date stamped, tracked, and logged to support compliance with regulatory agencies’ standards and guidelines
  • Protects employees identities/personal mobile numbers
  • Keeps employees personal life and professional life separate…as it should be

Secure Voice
Provides powerful and secure voice protection for highly sensitive calls

Place calls securely and with confidence


A Mobile Business Number for separating corporate SMS and voice communication from personal without the use of a container.

Today’s mobile user has become dependent on their mobile device for both personal and business use. This means that they conduct both sensitive and non-sensitive transactions from their mobile phones. As the use of mobile devices continues to proliferate, so does the need for greater encryption and traceability. Voice communication, often believed to be secure on mobile devices, is open to eavesdropping and intrusion, without additional safeguards.

The CellTrust SecureLine™ Mobile Collaboration Suite Secure Voice feature provides a high security, voice communication solution. It is a carrier independent, proprietary Session Initiation Protocol (SIP) implementation utilizing a strong integration with secure SMS encryption. Most Voice over IP (VoIP) solutions are unable to receive a call if the data connection is turned off, but a constant connection is costly to system and power resources. CellTrust provides the industry’s first solution to utilize the SMS control channel to wake the data connection to receive a call. The Secure Voice feature provides an increased reliability for call reception and potential savings on roaming costs.
