Zero-trust file protection when delivering cloud services

Existing security solutions leave cloud data at risk

It is common for Cloud Service Providers (CSPs) to deploy Cross Domain Solutions (CDS) to enable to the exchange of information between networks with a high degree of control.

However, legacy CDS rely on detection-based solutions, such as antivirus and sandbox technologies, and are unable to adequately protect CSPs and their clients against new (zero-day) threats. In addition, compliance with industry initiatives is difficult, as they are unable to verify complex data types, or remove active code within documents.

The solution:

Zero-trust file protection

with Glasswall CDR

Glasswall CDR’s Zero-trust file protection is different – instead of looking for malicious content, our advanced CDR process treats all files as untrusted, validating, cleaning and rebuilding each one against their manufacturers known good specification.

With Glasswall CDR, Cloud Service Providers can transfer critical data across secure networks to enable compliance with frameworks such as the UK’s NCSC pattern for Safely Importing Data & the US’ Raise The Bar strategy for cross domain solutions from the NSA.

“CDR is an important layer in any organization’s defence and content protection strategies… We expect CDR will ultimately be considered a best practice.”

Use cases

Secure CDS deployments

With Glasswall CDR Cloud Service Providers can transfer critical data across secure networks to enable compliance with frameworks such as the NCSC’s pattern for safely importing data, the NIST Risk Management Framework by the NSA and NCDSMO.

Our zero-trust philosophy removes security teams’ reliance on detection – replacing it with a zero-trust file protection solution that raises the bar on CDS protection.

Glasswall CDR adds the following functionality to your CDS:

  • Secure document, image, and media file transfer
  • Managed binary and CI/CD pipeline transfer
  • Transform complex data types to SISL/XML for syntactic verification
  • Image conversion to alternative formats such as bitmap
  • Data loss prevention via methods such as word search and redaction
