Emerson and OPSWAT announced a global strategic reseller agreement on April 16, 2026, embedding OT-native patch management into Emerson's Ovation Automation Platform for power and water operators worldwide. The deal marks the latest move by automation vendors to address chronic patching delays in operational technology (OT) environments, where unplanned downtime and safety obligations have historically constrained update cycles.
Background
Critical infrastructure operators in electricity generation, water, and wastewater face growing exposure to nation-state and ransomware campaigns targeting unpatched vulnerabilities in industrial control systems. Regulators have responded by tightening cybersecurity requirements for essential services, pressuring operators to demonstrate continuous vulnerability management without compromising plant availability.
Patching in OT environments has long posed a distinct challenge compared to IT networks. These environments often combine older industrial assets with newer digital systems, making software updates harder to manage without disrupting operations. Standard IT patch tools lack support for the deterministic timing requirements of programmable logic controllers (PLCs), human-machine interfaces (HMIs), and SCADA systems, where an ill-timed update can compromise production continuity or safety interlocks.
The agreement expands an existing relationship between the two companies. Under the prior DeltaV Alliance agreement, OPSWAT's MetaDefender Kiosk and MetaDefender Unidirectional Security Gateway were already integrated into Emerson's DeltaV Automation Platform.
Details
As the first initiative under the enterprise-wide agreement, Emerson will integrate OPSWAT's OT patch management capabilities into its Ovation Automation Platform, building on existing deployments of OPSWAT's MetaDefender Endpoint and My OPSWAT Central Management On-Premises within Emerson's power and water cybersecurity suite.
The Ovation Automation Platform is deployed at more than 800 sites globally, where cybersecurity technologies have already been adopted across the power, water, and wastewater sectors.
Robert Yeager, President of Emerson's power and water solutions business, stated that customers "need cybersecurity solutions designed specifically for operational technology - not adapted from IT," and that the collaboration helps operators protect real-time industrial systems "while supporting availability, performance, and safe operations."
OPSWAT's solution for the Ovation platform targets challenges posed by mixed modern and legacy environments, as well as rising nation-state and ransomware activity in the energy and water sectors. Benny Czarny, Founder and CEO of OPSWAT, noted that "cybersecurity cannot rely on traditional IT assumptions but must be deterministic, scalable, and engineered specifically for OT realities."
The new global partnership also reflects Emerson's broader strategy to collaborate with specialized cybersecurity providers, a shift driven by evolving global regulations and the need for continuous response to new vulnerabilities. Separately, OPSWAT recently debuted MetaDefender Aether, an AI-native decision engine designed to accelerate zero-day threat detection at the network perimeter, incorporating adaptive sandboxing and machine learning-driven threat scoring.
Outlook
The agreement positions both companies to address regulatory mandates that increasingly require operators to document and audit patch status across heterogeneous control system environments. As digital transformation accelerates across power and water infrastructure - expanding the attack surface - operators face continued pressure to implement OT-specific patch orchestration at scale. The scope of the enterprise-wide agreement suggests further integration phases beyond the Ovation platform, though neither company disclosed a product roadmap or timeline for subsequent initiatives.
