Stellar Cyber Open XDR Platform
• Ingests, normalizes, and enriches all your security data, including OT, endpoints, network, cloud, and logs into a single repository, replacing legacy SIEMs
• Automatically detects and correlates alerts using a proprietary multi-modal threat detection engine driven by machine learning
• Reduce attacker dwell time, minimizing attack impact
• Collects and detects in edge environments, including OT, with multi-function network security sensors
• Provides automated and manual response actions in real-time
Network Visibility Solution
Garland Technology
• Provides 100% complete network visibility through Network TAPs (Test Access Points) without affecting network traffic
• Optimize network monitoring through purpose-built Packet Brokers that allow advanced aggregation, filtering, load balancing, and deduplication
• Delivers inline Bypass TAPs to manage new inline tool deployments without disrupting operations
• Utilizes Data Diodes to segment network environments with unidirectional constraints
• Deployable solutions in specialized environments (e.g. OT) and in any form factor (hardware vs. virtual)

TAP -> TOOL
Stellar Cyber’s role in defending OT environments is to get telemetry from every relevant system, deploy its sensors for NDR and other network-based detections in relevant environments, and perform automated threat detection to power the security operations program. Garland Technology’s role in defending OT environments is to provide packet-level visibility, no matter the network architecture constraints, and provide unidirectional network segmentation.
The objective of deploying Stellar Cyber and Garland Technology is to get complete, cost-effective visibility which will ultimately deliver the best security outcomes. Both companies offer flexibility on specific products or components deployed depending on the deployment scenario. Use the below deployment matrix to understand how to deploy to defend your OT environment optimally. The deployment scenarios below reference the Purdue Model for Industrial Control Systems.
| Deployment Scenario |
Stellar Cyber Architecture |
Garland Technology Architecture |
| 1. Agentless network Security Sensors allowed in Level 3 and Level 2 | • Security Sensors deployed in Level 3 and Level 2 off of core switches • OT syslog collected directly to Security Sensors |
• TAPs optional depending on physical network requirements (media type/speed) |
| 2. Agentless network Security Sensors NOT allowed in Level 3 and Level 2 | • Security Sensors deployed in Level 4 off of packet broker • OT syslog collected via syslog server sending telemetry to Level 4 |
• Packet Broker deployed in Level 3 • Aggregator TAPs deployed in Level 2 sending traffic to Packet Broker • Data Diode optional depending on unidirectional requirements |
| 3. Require unidirectional connectivity between Level 4 and Level 3 environments | • Security sensors in Level 3 and below must be manually updated | • Data Diode deployed between Level 3 and Level 4 |
| 4. Legacy or unmanaged switches | • Security Sensors deployed in Level 3 and Level 2 off of Network TAPs, if allowed • Otherwise, Network TAPs feed Packet Broker, which then feeds Security Sensors |
• Network TAPs deployed to mirror switch traffic to Security Sensors |
| 5. DMZ hosts allow agents for security | • Agent Sensors deployed on DMZ hosts for telemetry collection | Does not affect architecture |
