Covert-channel detection

Liminal

Make hidden network behavior visible.

Network analysis designed to identify covert communication patterns and surface them to security teams in real time.

Liminal covert-channel detection interface

Overview

Liminal focuses on a difficult visibility problem: communication deliberately hidden inside otherwise legitimate network behavior. It analyzes traffic patterns and anomalies to highlight activity that conventional controls may overlook.

Real-time monitoring, configurable thresholds and structured reporting help analysts move from detection to investigation without losing operational context.

Core capabilities

01

Behavioral detection

Analyze traffic patterns and anomalies for subtle signs of covert communication.

02

Real-time monitoring

Surface suspicious activity as it develops instead of waiting for retrospective review.

03

Configurable alerting

Tune thresholds and route notifications into established security workflows.

04

Investigation context

Provide reports and analytics that help analysts understand scope and behavior.

05

Scalable architecture

Adapt deployment to research networks, focused environments or enterprise use cases.

Designed outcomes

Built to create practical value.

  • Earlier visibility into hidden communication paths
  • More focused analyst investigation
  • Reduced exposure to covert exfiltration and command channels
  • Evidence that supports security and compliance review
