Sentryo

What Sentryo does

Sentryo developed and provided cybersecurity and situational awareness solutions for industrial networks and the Internet of Things, founded in 2014 in Villeurbanne, France, with a headcount of 11-50 employees. The core technology was an OT (operational technology) visibility platform that used embedded sensors in network equipment to inventory industrial assets, profile communication behavior, and detect threats in industrial control system environments without requiring dedicated visibility appliances or SPAN collection infrastructure.

Following Cisco's 2019 acquisition, the technology was rebranded Cisco Cyber Vision and repositioned as part of Cisco's industrial IoT security portfolio. Cyber Vision is bundled at no incremental cost with select Cisco industrial Ethernet switches (IE3500 Rugged Series, IE3500 Heavy Duty Series, and Catalyst IE9300 Rugged Series) when purchased with a Network Advantage license, and is also available through AWS, Microsoft Azure, and Google Cloud Marketplaces.

The business model combines a hardware-bundled software subscription with cloud marketplace listings, distributed via Cisco's direct enterprise sales force, channel partners (notably Orange Business and Orange Cyberdefense), and hyperscaler marketplaces. Target customers are organizations operating critical infrastructure and industrial environments — utilities, energy, manufacturing, and water treatment — and OT security teams requiring self-service remote access and policy management. Cyber Vision integrates threat detection using the Snort IDS engine and Cisco Talos intelligence, and extends into Splunk and ServiceNow ecosystems for governance and ITSM workflows.

Core offering

Sentryo develops OT (Operational Technology) security software for industrial networks and IoT environments. Following its acquisition by Cisco in 2019, the technology is now offered as Cisco Cyber Vision, providing deep asset visibility, AI-assisted network segmentation, threat detection, and secure remote access embedded directly into Cisco industrial networking equipment (IE3500 and Catalyst IE9300 series switches).

Product overview

Cisco Cyber Vision is a unified OT security platform (formerly Sentryo, acquired by Cisco in 2019) that provides visibility, segmentation, and secure remote access built directly into Cisco industrial networking equipment. The core platform consists of Cyber Vision software embedded in Cisco switches and routers (IE3500 Rugged Series, IE3500 Heavy Duty Series, and Catalyst IE9300 Rugged Series), eliminating the need for dedicated OT visibility appliances. The solution integrates with Cisco's security ecosystem including Secure Firewall, Identity Services Engine, and XDR, as well as third-party platforms like Splunk and ServiceNow. Key security components include the Snort IDS engine and Cisco Talos threat intelligence. OT security operations are managed through Cisco Catalyst Center or SD-WAN Manager, with additional analytics available via the Cyber Vision App for Splunk. The platform leverages AI/ML for anomaly detection, recommendation-based segmentation, and threat prioritization using MITRE ATT&CK mapping.

Direct peers

• Nozomi Networks: OT and IoT security specialist providing deep asset visibility, threat detection, and vulnerability management across industrial protocols. Competes directly with Cyber Vision in utilities, manufacturing, and other OT-heavy verticals and is frequently benchmarked against Cisco's offering.
• Dragos: OT cybersecurity vendor focused on industrial threat detection, incident response, and asset inventory for critical infrastructure. Overlaps with Cyber Vision's visibility and threat-detection capabilities and is a frequent alternative for utilities and heavy industrial buyers.
• Claroty: Pure-play OT/ICS cybersecurity vendor offering asset discovery, vulnerability management, network segmentation, and secure remote access for industrial environments. Directly competes with Cisco Cyber Vision for the same critical-infrastructure and manufacturing buyer, often in head-to-head RFPs.

Emerging players

• Armis: Asset visibility and security platform covering IT, OT, IoT, and medical devices. Increasingly positioned against Cisco Cyber Vision in enterprise accounts seeking unified IT/OT asset intelligence and risk management.
• SCADAfence (now part of OPSWAT): OT and industrial cybersecurity vendor providing asset visibility, network monitoring, and threat detection. Competes with Cyber Vision in mid-market and European manufacturing accounts and was acquired by OPSWAT to scale broader critical-infrastructure protection.

Broad incumbents

• Tenable (Industrial Security / OT Security): Tenable's OT Security (acquired from Indegy) offers asset discovery, vulnerability management, and threat detection for industrial environments. Competes with Cyber Vision on the vulnerability-management and asset-inventory layer of OT programs.
• Fortinet (OT Security): Networking and security vendor with an OT Security solution that integrates with FortiGate and FortiNAC. Competes with Cisco Cyber Vision in industrial accounts already standardized on Fortinet networking, and increasingly in OT segmentation RFPs.
• Forescout: Broader network access control and device visibility platform with a strong OT/ICS security module. Competes with Cyber Vision on asset discovery and segmentation, particularly in enterprises already standardized on Forescout for IT/OT device visibility.
• Palo Alto Networks (OT Security, Zingbox): Large enterprise security platform with OT/IoT security capabilities inherited from Zingbox and integrated into Prisma and Cortex. Competes with Cyber Vision at the platform layer for CIO/CISO budgets spanning IT and OT security.
• Cisco Secure Network Analytics / Cisco XDR: Cisco's broader IT security portfolio, including XDR and Secure Network Analytics, overlaps with Cyber Vision on threat detection and analytics. While a sibling rather than a direct competitor, internal portfolio competition can constrain Cyber Vision's standalone positioning inside Cisco accounts.
