Regulators prefer architectural separation over policy-only controls

Founded by leaders in Internet and mobile security, when CellTrust launched its SL2 Enterprise app in 2013—it featured a dedicated Mobile Business Number™ (MBN) to enable secure, compliant mobile communications—the company anticipated that mobile would evolve into a critical business channel for authentication, communication and compliance.

A dedicated mobile business number for BYOD, COPE or COBO is a mobile phone number assigned specifically for business communications rather than personal use. In regulated industries, it’s an important compliance control because—from day one—it separates business communications from personal ones, making them easier to capture, supervise, and retain.

MBN for BYOD, COPE, COBO

Mobile device deployments are often where regulatory enforcement risk is highest. CellTrust SL2 architecturally separates business communications on the mobile device with an MBN, providing a defensible, inspectable technology design rather than relying on employee behavior.

• Employees keep one physical phone
• Firms issue a separate business number
• Personal and business traffic are cryptographically and operationally separated for BYOD
• Firms retain ownership of the business number, data and records
• Aligns with SEC and FINRA supervision rules, FC and MiFID II recordkeeping, Government public records and FOIA obligations
• Regulators prefer architectural separation over policy-only controls
