EmberOT

Overview

EmberOT is a self-hosted monitoring platform for industrial networks, using software sensors to track assets, vulnerabilities and operational activity. It is aimed at plant teams and industrial defenders who need OT visibility with data processed locally. Its central strength is putting asset discovery, contextual risk ranking and operational monitoring in one product; its free analyzer is for offline packet review, not continuous protection.

Key features

EmberOT’s sensors discover, classify and monitor industrial assets from remote network edges through core networks. Passive monitoring supports IEC 61850 (MMS/GOOSE/SV), Siemens S7, CIP/ENIP, BACnet, Modbus, DNP3 and MQTT. That breadth is useful for teams with varied industrial equipment, while self-hosting and local edge processing suit environments where monitoring data should remain close to the network. Minimum sensor requirements are 4 cores, 4 GB RAM and 30 GB storage.

Vulnerability evaluation uses real-time and historical data to rank risk in the context of a particular industrial environment, and the product provides environment-specific remediation recommendations. Cybersecurity alerts are paired with operational anomaly detection and process monitoring, giving teams a way to consider security issues alongside plant behavior rather than relying on vulnerability severity alone.

The Odyssey console brings sensor and license management, system health monitoring, asset inventory and network visualization together. EmberOT can use existing SIEM and SOAR infrastructure, and its full product can send data to SIEMs, SOARs and MSSPs. User management, streamlined authentication, downloadable threat logs and packet captures support access control and incident investigation. The maker also describes IgniteOnsite as a portable OT assessment and incident-response toolkit for air-gapped and offline deployments.

The free OT PCAP Analyzer identifies devices and protocols in packet captures and offers filtering, search and device-attribute lookup. It is a useful starting point for offline investigation, but lacks near-real-time span or tap monitoring, outbound data sending, historical disk storage, and threat or anomaly detection. Teams needing those capabilities need the main product.

Pricing

The main EmberOT product is paid, with custom pricing through a demo request. The company says it provides customers with dedicated support and guidance. That route fits organizations evaluating a broader OT deployment, but it offers no self-serve paid tier for teams that want to compare fixed prices.

The OT PCAP Analyzer costs nothing. It includes PCAP device and protocol breakdown, but downloading it requires a valid school or business email. Its offline-only scope makes it appropriate for examining captures, not for continuous monitoring or threat detection.

Platforms

EmberOT is self-hosted. Its hardware-agnostic software sensors process data locally at the edge, with minimum requirements of 4 cores, 4 GB RAM and 30 GB storage per sensor.

Who it's for

EmberOT is intended for industrial operators, engineers, defenders, plant managers, compliance managers and cybersecurity teams. Its combination of asset visibility, environment-specific vulnerability ranking and process monitoring is most relevant to organizations that need to connect cyber findings with industrial operations. IgniteOnsite may suit teams conducting assessments or incident response in restricted or air-gapped environments.

Pros and cons

• Contextual vulnerability ranking: Real-time and historical data inform risk in the specific industrial environment, alongside remediation recommendations.
• Security and operations in one view: Cybersecurity alerts, anomaly detection and process monitoring can help teams weigh security concerns against plant activity.
• Broad industrial protocol coverage: Passive monitoring includes IEC 61850, Siemens S7, CIP/ENIP, BACnet, Modbus, DNP3 and MQTT.
• Local, self-hosted processing: Edge-based sensors support organizations that prefer data collection and processing within their own industrial environment.
• Free analyzer has a narrow role: It handles offline PCAP review, but omits live span or tap monitoring, historical storage, outbound sending and threat or anomaly detection.
• Paid product requires a sales conversation: Custom pricing and demo-based access make it less suited to buyers looking for a published, self-serve plan.

Alternatives

Compare OT and ICS security monitoring software if you want to evaluate more tools in the category.

Honeywell Forge is worth considering for teams that want a broader platform available across Android, iOS, Linux, macOS, web and Windows; its offerings are product-specific and priced through Honeywell.

Nozomi Networks Platform may suit buyers looking for a free cloud-hosted Vantage SaaS option used to license hardware and Guardian nodes, alongside its paid platform.

Tenable One Attack Surface Management is an alternative for organizations seeking unified visibility across IT, cloud, web applications, OT and external attack surfaces.

Kaspersky Industrial CyberSecurity Platform is another paid option for enterprise OT and IoT environments, offered through a demo or sales contact.

NetPol may fit teams that want an Enterprise Dashboard priced at A$200 a month per node, with cloud-hosted or self-hosted deployment.

OTDefend offers a custom solution with tailored proposal and pricing.

Radiflow iSID is a self-hosted alternative offered through a demo request or sales contact.

Claroty CTD may suit organizations seeking on-premises deployment, federal OT cybersecurity controls or mobile flyaway kits.

Verdict

EmberOT is a strong fit for industrial organizations that want self-hosted asset visibility, environment-aware vulnerability ranking and operational monitoring in one system. The main reason to choose it is that security findings are considered alongside process behavior and plant context. Look elsewhere if you need a complete free monitoring product: the PCAP Analyzer is limited to offline capture review, and the full platform requires custom pricing through a demo request.
