InstaSafe Stick

InstaSafe USB provides the secure and controlled access to internal applications from external networks by administrators or power users, InstaSafe offers the InstaSafe Stick—a tamper-proof, encrypted, read-only Ubuntu-based bootable operating system deployed on a USB 3.0 drive. This hardened environment is designed to eliminate data leakage risks and enforce strict Zero Trust access policies.

Key Security Mandate Compliance

  • Isolated Boot Environment: The solution mandates access through a separate bootable system using a preconfigured USB OS, disallowing access from any host operating system.
  • Data Encryption and Isolation: All files created or accessed within the InstaSafe Stick environment are encrypted and cannot be opened or decrypted in any other OS or device.
  • Tamper-Proof and Read-Only: The USB drive operates in a read-only mode, preventing unauthorized modifications, thereby ensuring integrity and non-repudiation.

InstaSafe Stick: Technical Architecture

  • Base OS: Hardened Ubuntu (LTS version)
  • Deployment Medium: USB 3.0 Drive (8 GB or higher)
  • Boot Mode: Secure boot via BIOS/UEFI (user reboots and selects USB boot)
  • Network Access:
    • Whitelisted application access only
    • No access to external/public internet
  • ZTNA Integration: Secure tunnels for application-specific access
  • MFA Integration: Integrated support for OTP/Push via InstaSafe Authenticator

Use Case Scenarios

  • Secure Third-Party Access: Ideal for consultants, vendors, and remote employees who need limited and secure access to applications.
  • BYOD Environments: Enables use of personal or non-compliant devices without risking corporate data exposure.
  • Disaster Recovery or Remote Admin Access: Acts as a secure fallback environment for administrators during remote interventions.

User Workflow

  1. Insert InstaSafe Stick into a USB 3.0 port.
  2. Reboot system and select USB as the boot device.
  3. Hardened Ubuntu OS launches with InstaSafe ZTA preconfigured.
  4. Authenticate via MFA and gain access to permitted applications.
  5. Operate in a secure, isolated environment; any accessed data is encrypted.
  6. Remove USB on session completion — no trace or leakage on host system.

Benefits

  • Enhanced Security Posture: Isolated, hardened OS with no access to host system or public internet.
  • Compliance Ready: Aligns with regulatory and data protection mandates.
  • Rapid Deployment: Preconfigured, plug-and-play setup with no additional software installation.
  • Operational Efficiency: Reduces the need for expensive endpoint hardening or dedicated laptops for external users.
