A Mobile Business Number (MBN) is a dedicated US mobile phone number for BYOD, COPE or COBO assigned specifically for business communications rather than personal use. CellTrust SL2 architecturally separates business communications on the mobile device with an MBN, providing a defensible, inspectable technology design rather than relying solely on employee behavior.
SL2 Enterprise™ is CellTrust’s unified mobile communications (UMC) platform featuring a range of flexible connect, capture and supervision options integrated with many of the most popular collaboration tools such as SMS, MMS, RCS, WhatsApp, Microsoft Teams, agentic workflows, and voice. Employees can seamlessly connect with customers on-channel as opposed to off-channel, knowing their personal and business communications are separated within a compliant mobile environment.
While they collaborate with their peers and connect with their customers on the channels they prefer, IT and Compliance professionals can rest easy knowing SL2 Enterprise is leveraging robust, leading edge security and compliance to fullfil regulatory recordkeeping and supervisory requirements for electronic communications.
Archiving agnostic, SL2 Enterprise delivers out-of-the-box integration through strategic partnerships with the leading global Digital Communications Governance and Archiving (DCGA) platforms and modern compliance stacks with a unified mobile communications capture layer, enabling organizations of all sizes to meet global regulatory requirements.

Thanks to CellTrust’s seamless integration with Microsoft Teams, staff can engage with clients through text, WhatsApp, or Teams—all within the same platform. No additional apps or tools are required, ensuring smooth, efficient, and compliant communication every time. Designed with a familiar, intuitive interface — meaning minimal or no additional training is typically required — SL2 for Microsoft Teams offers versatile messaging with support for One-to-One, Group, BCC and WhatsApp messaging. Users can easily login to their work accounts via Microsoft Entra ID and sync Microsoft Outlook contacts for effortless unified communication.
SL2 for WhatsApp, enables regulated organizations in government, education, and finance to embrace WhatsApp without compromising compliance. Staff can securely engage with constituents, students, parents and clients — on the platform they prefer — without risking data breaches or policy violations. Whether it’s a government agency updating a constituent, a teacher answering a student, or a financial advisor responding to a client, SL2 ensures every message is captured, protected, and compliant—so you can say yes to WhatsApp without compromise.
It is no longer enough to just capture and provide data to compliance after communications have been already sent. SL2 Private AI stops data leakage and holds risky, potentially libelous content from being processed through the messaging gateway before it can reach recipients. Organizations operating within highly regulated industries such as government, financial services, and healthcare are required to put robust policies and supervisory systems in place to monitor and analyze all electronic employee communications for conduct violations such as abusive or threatening language, offensive or adult content or the disclosure of sensitive or confidential personal information.
SL2 Private AI automatically analyzes SMS, chat and WhatsApp messages over the SL2 channel within a predefined moderation template, automatically detecting messages that may require scrutiny. SL2 Private AI scans mobile communication content over the SL2™ channel for:
SL2 channel SMS, chat and WhatsApp messages with a high risk score are automatically detected and held for review because they may potentially conflict with enterprise data governance and compliance policies. The moderator can approve or block the message, and the sender will automatically be notified. Compliance teams wanting more control can set or adjust moderation policies, automatically assign risk values to specific content, or add a custom list of words or specific content strings to be flagged within the SL2 Private AI portal.
CellTrust’s SL2 Private AI combines traditional AI with advanced decision-making capabilities to support analysis and operational efficiency. It does not use Generative AI (GenAI) or Artificial General Intelligence (AGI)—meaning no machine learning or content generation occurs. Most importantly, SL2 Private AI never shares customer data with AI models or third-party AI learning services. Your proprietary enterprise data stays exactly that—proprietary.
