WHAT IS CONTENT DISARM AND RECONSTRUCTION (CDR) TECHNOLOGY?

Also known as ‘file sanitization’ or ‘content sanitization’ – Content Disarm and Reconstruction (CDR) is an advanced technology providing superior results in the prevention of file-based attacks – effectively blocking the initial access phase of most APT’s, ransomware and zero-day attacks.
CDR generates for each incoming email and file, a functionally identical new copy that is devoid of any malicious content or links- transparently, in near real-time.

A major benefit of CDR is that it eliminates reliance on user judgement and compliance, since all incoming content is disarmed prior to entry.
An added benefit of the technology is the capacity to apply precision data redaction to the outgoing stream, enabling the prevention of data exfiltration or loss, supporting data-protection and privacy policies (GDPR/CCPA) compliance.

How DOES CONTENT DISARM AND RECONSTRUCTION (CDR) TECHNOLOGY WORK?

Content Disarm and Reconstruction dissects each incoming (or outgoing) file to its most elementary components and scans the components with NextGen AI and multi-AV tools with superior results. It then reconstitutes the files, in strict adherence to their vendor specifications, disrupting in process any remaining, undetected (‘signature-less’) malware (see our ‘Before & After CDR Processing’ samples page).
A good CDR solution combines deep Deconstruction/Reconstitution processing, coupled with high-throughput capacity.

Content Disarm and Reconstruction stages

1. File deconstructed to its elementary components
2. Deep threat detection ('deep CDR'): TrueType identification, highly optimized Multi-AV scans, NextGen AI detection, file signature verification - applied to each component separately.
3. Proprietary disarming of the components from any potentially harmful elements such as macros and embedded scripts
4. Advanced file reconstruction, removing in the process undetectable weaponized content, exploits and all components that do not meet the designated security policy

Why GateScanner?

Excellence. We are certain that our CDR technology is practically impregnable. Our clients’ independent penetration tests repeatedly show up to 99.99 % success rates in the obstruction of unknown, file embedded threats, and that’s the bottom line – but that’s not the whole story…

Modularity. Adding a new component to an existing system can be a major challenge, and flexibility is the key to a successful implementation. With this in mind, we’ve built GateScanner to be modular, highly configurable and easily scalable. Pick and choose any part of the CDR process you want to implement, select which channels to protect, and chain up to ten GateScanner engines on-the-fly, to achieve virtually unlimited processing capacity.

Easily Integrated. Challenged to deliver unique solutions for a wide variety of client configurations, GateScanner features a unique integration engine that enables security teams to insert content sanitization processing at any point along the data flow, either before or after existing security tools, notching-up the security profile of the network significantly.

Customizable. For us, every client is an opportunity to get creative. Our highly dedicated development team works closely with each client to fulfill their most ambitious goals.
We look forward to creating your solution!

Experience. GateScanner is in continuous development since 2013. With a diverse client-base, ranging from government security agencies and defense contractors, through multi-national manufacturing industries and critical infrastructure providers, to financial institutions and national healthcare providers, we consistently deliver our proven technology and maintain our clients’ continuing trust year after year.
