| Abstract: |
Contemporary cybersecurity is awash with marketing buzzwords, new threat models, and endless promises of “next-gen” security. It is also heavily over-reliant on detection-based technologies, often at the expense of unknown and zero-day threats slipping through defenses. In particular, one dangerous attack vector is still being exploited in plain view: file-based threats, which remain a go-to tactic for delivering malicious payloads. To mitigate these risks, organizations are increasingly adopting file sanitization technologies, commonly known as Content Disarm and Reconstruction (CDR), to proactively remove hidden threats and strengthen the wider security capabilities of their estates, including EDR, XDR, antivirus and sandboxing. Fundamentally, file sanitization neutralizes file-borne and human-interactive threats by enforcing a “clean-by-default” model that removes risk rather than interpreting it. In this environment, adversaries are forced to work harder, while, from the SOC perspective, detection pipelines remain cleaner and teams regain clarity rather than being overwhelmed by alerts. To understand how file sanitization enhances defensive effectiveness, Glasswall’s Head of Security Research, Connor Morley, and DevSecOps Engineer, Chris Holman, conducted an in-depth study processing real-world malware variants with and without sanitization. The findings reveal how CDR amplifies the performance of deployed detection tools across security metrics, including alert volume, false positives, and downstream operational efficiency. While no system achieves 100% coverage, the session will demonstrate how integrating file sanitization supports Zero Trust objectives. Attendees will gain a realistic view of how clean-by-default file protection strengthens modern defensive architectures and reduces hidden operational strain.
