Mobile Watermark

Structured mobile security for enterprise-owned and BYOD Android devices with dynamic app whitelisting, capture restrictions, and automated anti-tamper enforcement across managed Work Profiles.

As mobile workforces expand across enterprise-owned devices and employee smartphones, preventing screen-based data leakage is a critical challenge. Mobile security fails when endpoints rely on manual configurations or easily bypassed permissions. xSecuritas Android Mobile Configuration provides a structured security layerβ€”delivering dynamic app whitelisting, capture restrictions, and automated anti-tamper enforcement across managed devices and Work Profiles.

Why It Matters

  • Unmanaged Mobile Capture:Β Unprotected mobile screens allow unauthorized screenshots and screen recordings.
  • BYOD Compliance Challenges:Β Mixing personal and enterprise data on employee devices creates security and privacy conflicts.
  • Permission Revocation:Β Users can manually revoke permissions to bypass security policies unless anti-tamper mechanisms are enforced.
  • Unauthorized App Usage:Β Shadow IT and unapproved third-party mobile apps introduce operational risks.
