By combining isolation technology and CDR, we enable a fully zero-trust file security solution that isolates
the threat and enables a secure and safe methodology to move the file into the trusted organization's
resources.

The Need for Removable Media Isolation

Today, organizations typically employ device control solutions to reduce the attack surface posed by
removable media such as USB drives, CDs, and DVDs. However, restricting user access is inherently
flawed, as employees often need to connect removable media for legitimate purposes. This dilemma
leaves organizations with two options: disabling device control entirely, thereby sacrificing security, or
directing users to a sanitization station or kiosk where they can scan removable media and utilize CDR
for zero-trust file security. A third, more effective option is to use endpoint isolation technology. With this
approach, when a user inserts removable media, it is automatically isolated, allowing the user to securely
access the removable media and select which content to save and transfer to the organization's network.
By automatically combining isolation and CDR, users no longer need to visit a sanitization station or
request the organization to bypass its security mechanisms, thus maintaining robust security while
accommodating legitimate needs.

Conclusion

As cyber threats become more sophisticated, the limitations of detection-based security solutions
become increasingly apparent. Enterprises must embrace a preventive approach to endpoint security
centered around application isolation and zero-trust file security. By doing so, they can significantly
reduce their attack surface and safeguard their systems against even the most advanced threats. The
future of endpoint security lies in proactive measures that prevent threats before they can cause harm,
ensuring a resilient and secure digital environment for all.
