Armis announced on March 6, 2025, that it had acquired OTORIO, with plans to integrate OTORIO’s Titan platform into Armis Centrix. The stated aim is to extend Armis’ operational technology (OT) and cyber-physical systems (CPS) security offering to industrial and critical-infrastructure environments, including sites that need on-premises or fully air-gapped deployment. ANDRITZ later confirmed that it sold its stake in OTORIO and that Armis became its full owner.
Why did Armis buy OTORIO?
Armis framed the acquisition as a way to address OT and CPS environments where conventional cloud-connected security services may not fit. Its March 6 announcement said it planned to integrate OTORIO Titan with Centrix and add an on-premises CPS option for organizations whose systems are disconnected from the internet or otherwise isolated. The company named heavy industry and critical infrastructure, including energy and utilities, as target settings. Armis’ acquisition announcement
OTORIO, founded in 2018 according to Armis, brought experience in heavy industry and critical infrastructure. Armis cited customers and use cases in oil and gas, utilities, and manufacturing, as well as secure remote access and attack-path mapping. These capabilities address different operational needs: remote access can support authorized access to industrial systems, while attack-path mapping can help reveal routes through which an attacker might reach important assets. The announcement did not provide independent performance measurements for either capability.
What is OTORIO Titan, and what did Armis plan to do with it?
Titan is OTORIO’s platform for OT and CPS security. Armis said it would integrate Titan into Centrix, its cloud-based cyber exposure management platform, to extend the combined offering into industrial environments and support deployments that cannot rely on a cloud connection. The announcement described an integration strategy, not a feature-by-feature release schedule; it does not establish that every announced capability is available in a current product release.

In a March 6 executive blog, Armis CEO Yevgeny Dibrov described intended choices spanning on-premises, hybrid, and cloud deployment. He also highlighted secure remote access and advanced attack-path mapping. The practical distinction is where the system runs and how much network connectivity a site permits—not a claim that one deployment model is universally preferable. Dibrov’s announcement blog
| Announced dimension | What it means for a potential deployment |
|---|---|
| On-premises | Intended for organizations that need security capabilities hosted within their own environment. |
| Air-gapped or sequestered | Intended to address sites with no direct online access or tightly restricted connectivity. |
| Hybrid or cloud | Additional deployment choices Dibrov described as part of the integration strategy. |
| Secure remote access and attack-path mapping | Capabilities Armis named for industrial and critical-infrastructure use; delivery timing was not specified. |
How much did Armis pay for OTORIO?
Armis did not disclose official deal terms. TechCrunch reported on March 6, 2025, that the price was $120 million in cash and shares, citing unnamed sources close to the transaction. That figure is a media report, not a company-confirmed purchase price. TechCrunch’s report

Who owns OTORIO now?
On March 14, 2025, ANDRITZ said it had sold its stake in OTORIO to Armis and that Armis then held full ownership. ANDRITZ also announced a strategic partnership with Armis to add technology to its Metris digital platform. ANDRITZ CEO Joachim Schönbeck said the company viewed Armis as the right partner to further develop OTORIO’s products and offerings; that is a company statement, not an independent product assessment.

What does the acquisition mean for air-gapped OT security?
The strategic significance is that Armis said it intended to bring an on-premises option to customers whose industrial or critical-infrastructure environments cannot use an always-connected cloud service. Dibrov said in the acquisition announcement: “Through this acquisition, Armis can now offer an on-premises solution for customers that require a fully air-gapped environment for heavy industry and critical infrastructure like energy or utilities.” Because that statement described the acquisition’s intended product direction, organizations should confirm the availability and technical fit of specific features with Armis rather than assume they are already delivered.
- For isolated sites: clarify how the proposed deployment handles updates, monitoring, administration, and any necessary data movement without online access.
- For hybrid environments: establish which functions stay on premises and which, if any, depend on cloud connectivity.
- For remote operations: confirm how secure remote access is controlled and whether it is supported in the intended network architecture.
- For risk visibility: ask what assets and attack paths the deployed product can identify in the specific OT environment.
What the announcement does—and does not—establish
The acquisition announcement establishes Armis’ stated rationale, planned Titan integration, and the deployment models and capabilities it intended to pursue. ANDRITZ’s later announcement establishes the ownership outcome. The public materials cited here do not specify feature-by-feature completion dates or independently verify performance in customer environments.
