CBFS™ Filter lets you intercept, monitor, and control filesystem, registry, and process manager operations in real time. All without writing a single line of kernel driver code.
CBFS Filter gives you real-time visibility and control over filesystem, registry, and process activity, all without writing driver code. If it touches the filesystem or the Windows kernel, you can intercept it.
Audit logging and compliance
Record a complete, tamper-evident log of every file access, modification, and deletion across the system. Identify which process touched which file, when, and under which user account. Provides everything compliance and forensics teams need.
File isolation and per-process views
Present different file contents to different processes accessing the same path. One process sees the live decrypted file; another sees only the encrypted version on disk. Useful for sandboxing, DRM enforcement, and secure multi-tenant environments.
Continuous data protection
Intercept every write operation as it happens and capture incremental backups in real time. Recover any version of any file from any point in time, without waiting for a scheduled backup window.
Process and application control
Monitor process and thread creation, restrict which applications can launch, and guard against potentially unwanted programs. Enforce application whitelisting or blacklisting at the kernel level, transparently to end users.
Registry protection and redirection
Intercept registry reads and writes to protect sensitive keys, redirect requests to alternate locations, or inject virtual registry values that only your application controls. Useful for application isolation, licensing enforcement, and configuration management.
Real-time malware and ransomware defense
Block malicious file operations the instant they happen, before a file is encrypted, deleted, or exfiltrated in bulk. Build the detection and blocking engine behind an antivirus or anti-ransomware product without writing driver code.
No kernel code required.
Kernel programming is hard, and writing a minifilter driver from scratch means dealing with complex Windows internals, strict altitude requirements, mandatory driver signing, and the ever-present risk of a system crash if something goes wrong. CBFS Filter provides a safer, more flexible approach: it ships with a pre-built, Microsoft-signed minifilter driver that acts as the intermediary between the filesystem and your application code.
Filesystem, registry, and process manager operations are proxied into callback events that execute in a separate user-space process. You implement handlers for the events you care аbout: intercept a file open, redirect a registry read, block a process from launching — without ever touching kernel code. Advanced filter rules let you precisely target only the operations relevant to your application, so you're never flooded with events you don't need.
With over 20 years of experience and trusted by security vendors, backup solutions, and enterprise software teams around the world, we understand the kernel so you don't have to.
