Armis announced its acquisition of OT and cyber-physical systems security company OTORIO on March 6, 2025. The deal was intended to add OTORIO’s Titan platform to Armis Centrix, giving industrial and critical-infrastructure customers a path to cloud, hybrid, or on-premises exposure management—including deployments that are air-gapped or disconnected from online services.
What Armis bought
Armis said OTORIO’s Titan platform would be integrated into Armis Centrix, its cloud-based cyber exposure management platform. The combination was presented as an expansion of Armis’s OT and cyber-physical systems coverage rather than a replacement for Centrix.
OTORIO’s industrial-security focus was intended to strengthen support for environments such as heavy industry, energy, utilities, oil and gas, manufacturing, and other critical infrastructure. Armis also described an on-premises CPS option for customers whose sites cannot connect to cloud services.
Why the acquisition matters for industrial customers
Air-gapped and disconnected sites
Many industrial control environments restrict or prohibit direct internet access. Armis CEO and co-founder Yevgeny Dibrov said the acquisition would let Armis offer an on-premises solution for customers requiring fully air-gapped deployments in heavy industry, energy, and utilities. That is a stated company objective, not an independently tested result.

#1 Best Overall
One exposure view across IT and OT
Armis positioned the deal as a way to combine its broader exposure-management platform with OT-specific technology. In principle, that can help security teams relate industrial assets and cyber-physical systems to vulnerabilities, attack paths, and operational risk without forcing every site into a cloud-only architecture.
Capabilities named in the announcements
- Secure remote access (SRA) for controlled connectivity to industrial environments.
- Attack-path mapping to identify routes through which an attacker could reach important assets.
- Risk-based vulnerability management that prioritizes weaknesses according to exposure and potential impact.
- OT and CPS asset visibility intended for industrial and critical-infrastructure operations.
These are capabilities associated with OTORIO and the planned integration described by the companies. The announcements do not independently establish how completely each feature was integrated, when it became generally available, or how it performs in a particular plant.
Acquisition and ownership timeline
| Date | Event | What was disclosed |
|---|---|---|
| March 6, 2025 | Armis announcement | Armis announced that it had acquired OTORIO and said Titan would be integrated into Centrix. |
| March 14, 2025 | ANDRITZ confirmation | ANDRITZ said it sold its stake in OTORIO to Armis, leaving Armis with full ownership. ANDRITZ and Armis also announced a strategic partnership to add technology to ANDRITZ’s Metris digital platform. |
| April 20, 2026 | ServiceNow completion | ServiceNow announced that it had completed its acquisition of Armis. ServiceNow said Armis Centrix remained available as a standalone solution, supported by ServiceNow’s product, engineering, and go-to-market organization, and integrated with the ServiceNow AI Platform. |
As of the April 20, 2026 completion announcement, Armis is part of ServiceNow. Describing Armis as an independent, privately held company would omit that subsequent ownership change.
How much did Armis pay for OTORIO?
The companies did not disclose a purchase price in their announcements. TechCrunch reported an estimated payment of $120 million in cash and shares, citing unnamed sources close to the transaction. That figure is a reported estimate, not a confirmed price from Armis, OTORIO, ANDRITZ, or ServiceNow.

Armis described the OTORIO transaction as its third acquisition in less than 12 months. It also claimed a 2,000% increase in related revenues after earlier acquisitions of Silk Security and CTCI. That percentage is an Armis statement about those earlier transactions; it is not independent evidence of OTORIO’s financial contribution or the value created by this deal.
ANDRITZ’s continuing role
ANDRITZ’s March 14, 2025 announcement did more than confirm the transfer of its OTORIO stake. It also established a strategic partnership with Armis involving technology for ANDRITZ’s Metris digital platform. ANDRITZ CEO Joachim Schönbeck said Armis was the right partner to further develop OTORIO’s products and offerings and provide customers with more comprehensive solutions.
Rank #4
The partnership may create implementation and integration opportunities for industrial operators, but the announcement does not establish a referral program, affiliate arrangement, pricing, or specific service availability.

The acquisition announcement sets out a strategic direction, not a neutral product test or a complete delivery schedule. Organizations evaluating the resulting offering should verify the details that matter to their site:
- Deployment: Confirm whether the required functions run fully on-premises, in a hybrid model, or through Centrix cloud services.
- Air-gap operation: Ask how updates, data transfer, administration, and incident response work when a site has no online connection.
- Remote access: Establish which users, vendors, and maintenance workflows are supported by secure remote access and what controls are enforced.
- OT visibility: Check support for the plant’s industrial protocols, controllers, engineering workstations, safety systems, and other CPS assets.
- Risk prioritization: Determine how vulnerability and attack-path findings are ranked against operational safety, uptime, and business impact.
- Integration: Confirm compatibility with existing security operations, asset-management, Metris, and ServiceNow workflows.
- Lifecycle and support: Get current licensing, version, support, and upgrade commitments directly from the vendor or an authorized integrator.
What the deal does—and does not—prove
The transaction clearly broadens Armis’s stated OT/CPS strategy and addresses a requirement that cloud-only security platforms cannot meet: operation in constrained or fully air-gapped environments. It also links OTORIO technology to Armis Centrix and, after ServiceNow’s 2026 acquisition, to the ServiceNow AI Platform.
It does not by itself prove a particular security outcome, integration completion date, performance level, or customer return on investment. Those questions require current product documentation, contractual commitments, and site-specific validation.
