What it sells: Network Critical

What Network TAPs does[1][3]
A network TAP creates an exact copy of all data flowing between two points in a network. TAPs are used to monitor network traffic for performance, security, or compliance.
What Packet Brokers does[1][7][8][13]
Network packet brokers process inputs from multiple sources and deliver the right traffic to the right tools. SmartNA-PortPlus is a packet broker that aggregates low-speed links onto fewer high-speed tools.
What Hybrid TAP and Packet Broker does[8]
A hybrid test access point and packet broker combines the functions of a TAP and a packet broker in one package. Hybrid TAP and packet brokers offer traffic aggregation, load balancing and port mapping. They use interchangeable, hot-swappable TAP modules, including fail-safe copper.
What Bypass TAPs does[9][10]
A bypass TAP monitors security devices and reroutes network traffic around failing tools. Bypass TAPs send small test signals, known as heartbeats, to security appliances. SmartNA-XL bypass TAPs detect when inline security tools fail and redirect traffic in real-time.
What INVIKTUS does[1][11][12]
INVIKTUS is a zero-trust security solution. INVIKTUS network security is built on the zero-trust framework and analyzes and validates traffic.
What Ethernet TAPs does[6]
Ethernet TAPs capture network traffic without impacting performance. Ethernet TAPs can be deployed as standalone TAPs or within SmartNA chassis for advanced traffic management.

About Illumio

Illumio is a security company that sells the Illumio Breach Containment Platform, which includes Illumio Insights and Illumio Segmentation for hybrid and multi-cloud environments.[1][7]

Illumio says it addresses lateral movement, the workload-to-workload movement inside an environment. Illumio says cloud-native controls were not built to cover this east-west traffic, and that each cloud provider has its own console, so there is no single policy view across Azure, AWS, GCP and OCI.[8]

Illumio Insights is described on the Illumio site as a tool to identify lateral movement, detect attacks, and stop breaches at cloud scale. Illumio says it is powered by an AI teammate called Insights Agent, which supports prioritisation of threats with context-rich analysis, deep observability, and one-click containment.[1]

Illumio Segmentation is described as a way to secure critical assets, workloads, and devices across a hybrid, multi-cloud environment. Illumio says it lets customers see risk, set policy, and prevent lateral movement.

For cloud security, Illumio says its platform works across the data center, endpoints, containers, Azure, AWS, GCP, and OCI, with or without an agent. Illumio says policy is label-based and follows the workload through auto-scaling, redeployment, and IP changes. Illumio says Draft-view shows which connections a rule would change before it goes live.[8]

Illumio publishes pages for several industries. For financial services, Illumio says it helps secure systems from core banking to mobile apps. For energy and utilities, Illumio says it helps operators identify risks, detect threats, and contain breaches across IT and OT systems. For healthcare, Illumio says it blocks the spread of attacks across IT, OT, and medical devices. Illumio also has pages for government, manufacturing, telecom, and small and midsize businesses.[9][10][11][15]

For compliance, Illumio names GDPR, HIPAA, PCI DSS, and DORA, and says it can generate audit-ready evidence of segmentation, policy enforcement, and breach containment efforts. Illumio says Microsoft deploys Illumio across its entire corporate IT environment.[3][12][13][14][16]
