Cisco Splunk

Cisco Splunk Integration

Bring OT security events into your SIEM to unify SOC operations, improve visibility and accelerate detection

Centralized OT and IT security visibility

Real-time security event forwarding

Context-enriched events for SOC analysts

Single SOC for isolated environments

Cisco Splunk introduction

Cyberium enables continuous and secure forwarding of OT network logs and security events to existing IT SIEM platforms such as Splunk through a unidirectional architecture. Events are transmitted without any inbound connectivity, allowing centralized monitoring, correlation and incident detection while preserving strict isolation of industrial environments.

 

Through dedicated integrations (e.g. Splunk APIs), Cyberium enriches OT logs with contextual information — including asset, process and metadata context — delivering high-value security events that are immediately usable by SOC teams. This approach enables OT/IT convergence within a single SOC, eliminating the need for parallel monitoring infrastructures in high-security environments.

Key Cybersecurity Challenges to Overcome

Operational Imperatives Driving OT/IT Convergence
Enterprise analytics and optimization depend on continuous, real-time access to industrial data streams
Batch or delayed replication breaks operational value
The Cybersecurity Risks of Traditional Integration
Two-way protocols create persistent attack paths into OT
Firewalls lack context for industrial data flows and rely on rules that cannot prevent zero-day or unknown threats
Monitoring systems become high-value pivot targets
