Global Intelligence Operations: Data Ingestion and Public Safety.

Case Study: Lawful Interception with Zero Data Loss

Law Enforcement Agency - Undisclosed location

Extremely high malware exposure due to external interception sources

Zero tolerance for data loss — intercepted data cannot be retransmitted

Sustained 10 Gbps throughput with thousands of small files per second and occasional large payloads

Strict isolation requirements between public and classified environments

Need / Problem / Context

Secure Ingestion of Lawful Interception Data into Classified Environments

A national law enforcement agency needed to receive near real-time lawful interception traffic over HI2 and HI3 interfaces into a classified (“Secret”) network. This data, originating from telecom operators and external interception points, had to be continuously ingested and made available for analysis within a highly secure environment. The challenge was to ensure seamless, high-throughput data transfer while strictly preventing any risk of data leakage or backflow from the classified network, in compliance with stringent internal security and regulatory requirements.

Solution deployed

To meet both performance and security constraints, Cyberium deployed a high-throughput unidirectional architecture combining hardware isolation with application-layer controls and buffering mechanisms.

Hardware appliance

OWA 3U pack @ 10 Gbps

High-performance data diode ensuring strict one-way transfer from public to classified network.

Protocol Connector

Standard Connector (SFTP)​

Standard connector enabling structured and controlled file ingestion across domains

Increased Security Option

Dual-engine Antivirus Scanning

Inline inspection of incoming data to mitigate malware risks before entering the secure network.

BitDefender ClamAV Logos
Hardware Options

10 TB Buffering System

Absorbs burst traffic and guarantees reliable delivery without packet or file loss.
