Continuous full PCAP capture via hardware network TAPs. Every packet captured. Every alert forensically validated. Every log cross-referenced against network truth. Without this sensor, you’re trusting compromised systems to tell the truth.
The Problem
Traditional security tools rely on logs generated by the systems they’re supposed to be protecting. But once an attacker gains access, those logs can be deleted, modified, or fabricated. Your SIEM is only as honest as the systems feeding it.
First thing attackers do is clear event logs and disable logging services.
Sophisticated attackers inject false log entries to create misleading trails.
Log sampling, rotation, and agent failures create blind spots attackers exploit.
The FVDR sensor solves this by capturing network truth - packets that cannot be tampered with.
What Makes It Different
Patented technology ensures every alert is backed by immutable forensic evidence.
Court-admissible chain of custody from packet to prosecution.
Full packet capture of all network traffic - not samples, not metadata, not NetFlow.
100% network visibility with zero blind spots or gaps.
Direct collection from original sources, eliminating tampering risks.
Cryptographically validated from source to storage.
Hardware network TAPs ensure zero packet loss and complete visibility.
No SPAN port limitations, no dropped packets, no compromises.
Forensic Validation Process
Endpoint telemetry, SIEM alerts, firewall logs, and cloud events stream in from various sources. These are inherently untrusted - they come from systems an attacker may have already compromised.
Every log entry is compared against continuous full PCAP data captured by hardware TAPs. The network cannot lie - packets are the ground truth.
Logs that match network reality are validated. Logs with no corresponding network evidence are flagged - they may be fabricated by malware or missing critical context.
Validated alerts ship with complete forensic evidence - PCAP extracts, session timelines, chain of custody records. Ready for incident response, legal proceedings, or regulatory disclosure.
Business Impact
Every alert is verified against actual network traffic before it reaches your team.
Complete chain of custody from packet to prosecution. Meet SEC 4-day disclosure requirements.
Identify the exact breach moment, affected systems, and lateral movement path with forensic certainty.
Built for HIPAA, PCI-DSS, SOX, CMMC, and SEC disclosure timelines. Evidence that stands up.

The Foundation
The FVDR Network Sensor is the core intelligence source that powers the entire CyberDNA platform. Without forensically validated network data, every other data source - endpoint telemetry, cloud logs, SIEM events - remains inherently untrusted.
With FVDR, those same data sources become forensically corroborated. The sensor transforms your security stack from “probably fine” to “provably true.”
