Xona, founded in 2017, sells secure remote access to the industrial control systems of critical-infrastructure operators. It brokers each session through its own gateway, so the connecting device never joins the control network. Its Active Defense feature lets a customer stop threats during a live remote session. Xona's named customers are GE Vernova, RWE, Baker Hughes, Egyptian LNG and AltaGas. Xona raised $18 million in a strategic round led by Energy Impact Partners, for a total of $32 million raised. Customers deploy Xona's gateway at each site, so replacing Xona is an effortful project, and a larger one for a customer with more sites. Nozomi Networks, whose asset-discovery sensor runs on Xona's gateway, sells to the same buyers and could extend into secure access.

It defends conventional OT networks, devices, applications, and users and maps to the Cyber Defense Matrix. [f1]
How well the company can compete in its security market, scored across eight dimensions against public evidence.
| Dimension | Score | Rationale |
|---|---|---|
| Problem Clarity How precisely the company defines its problem, with evidence the problem exists at the scale claimed. | 4/5 | Xona names a specific buyer, critical-infrastructure operators connecting engineers, vendors, and contractors to OT systems such as HMIs and engineering workstations, and ties it to a quantified pain. Industry surveys it cites show remote access paths remain a primary driver of OT security incidents, and a 2026 joint CISA advisory documents state-linked actors exploiting programmable logic controllers across US critical infrastructure and urges routing remote access through a gateway that enforces multifactor authentication, corroborating the problem beyond Xona's own framing. [s1, s4, s12] |
| Capability Depth How specific the technical capabilities are, with evidence beyond marketing claims such as docs and third-party validation. | 3/5 | Xona describes its session-brokering architecture (protocol isolation across RDP, VNC, SSH, and web) and the Active Defense capability on its own platform pages, but no docs portal, demo, OSS, or third-party benchmark appears, and the Nozomi-certified integration is a partnership signal rather than an independent evaluation of Xona's own capability. [s1, s5, s6] |
| Market Timing Whether the market is ready for this product, with evidence that buyers are actively seeking solutions. | 4/5 | Regulatory frameworks including NERC CIP, IEC 62443, and TSA SD2 demand demonstrable governance over OT access, a buyer-side driver, and a 2026 CISA advisory documents state-linked actors exploiting programmable logic controllers across US critical infrastructure. Gartner now tracks a Cyber-Physical Systems Secure Remote Access market that lists the Xona Platform, and Xona shipped Platform v5.5 in February 2026 and Active Defense in March 2026 into that demand window. [s4, s5, s12, s13] |
| Team Credibility Demonstrated domain expertise with public signals such as prior exits, publications, and industry recognition. | 3/5 | Founder and CEO Bill Moore and a named executive bench, including a CFO, CRO, and CPO, are publicly identifiable and front the company in funding and product announcements. No verifiable prior security exit or sustained external publication record in the OT domain surfaced in public sources, holding the score at adequate. [s3, s8, s7] |
| GTM Proof Evidence of actual traction (customers, revenue signals, partnerships) beyond stated intentions. | 4/5 | The named operators on Xona's own site (GE Vernova, RWE, Baker Hughes, Egyptian LNG, AltaGas) are now backed by independent corroboration: 11 verified Gartner Peer Insights reviews of the Xona Platform averaging 4.8 out of 5, the independently announced Nozomi-certified integration, and reputable Energy Impact Partners backing. Multiple named references plus an independent third-party signal place the traction past vendor-displayed logos. [s2, s13, s6, s3] |
| Funding Efficiency Whether funding matches go-to-market ambition, with signs of capital-efficient growth. | 3/5 | Xona raised a 2024 strategic round led by Energy Impact Partners that its SEC Form D reports as $19,026,905 sold, lifting the disclosed total to $32 million, a raise sized to an OT enterprise motion with visible output in two 2026 platform releases. Private financials prevent confirming output per dollar at the level a strong score would require, but the round is now corroborated by a regulatory filing. [s3, s11, s4] |
| Category Clarity Whether the company creates or fits a recognizable category that buyers can quickly place in their stack. | 4/5 | Gartner tracks a Cyber-Physical Systems Secure Remote Access market and lists the Xona Platform in it, independent analyst confirmation that buyers place the category without vendor coaching. Xona uses the label consistently while positioning against legacy VPNs and jump servers, and the NERC CIP, IEC 62443, and TSA mandates it maps to name the same category buyers already fund. [s13, s1, s4] |
| Incumbent Defensibility How vulnerable the core value proposition is to absorption as a feature by a platform vendor. | 3/5 | Session brokering and protocol isolation raise the bar above a trivial feature release, and the regulated-buyer purchase process slows replacement. Broader cyber-physical-systems platforms such as Claroty and Dragos, and integration partner Nozomi, sell to the same plant operators and could fold remote access into a wider purchase, so the moat is real but not insurmountable. [s6, s1] |
Xona sells secure remote access to critical-infrastructure operators who must let engineers, equipment vendors, and contractors reach OT systems without exposing those systems to the user's endpoint or the wider network. The product targets HMIs, engineering workstations, and control-system applications across energy, utilities, oil and gas, manufacturing, maritime, and aviation, and positions itself as a replacement for legacy VPNs and jump servers.
Independent drivers corroborate the demand. Xona points to industry surveys showing remote access paths remain a primary driver of OT security incidents, and a 2026 joint CISA advisory documents state-linked actors exploiting programmable logic controllers across US critical infrastructure, with prior CISA advisories flagging the same actors targeting remote access pathways into water and energy. Regulatory frameworks including NERC CIP, IEC 62443, and TSA SD2 add audit pressure that the access layer must answer. [s1, s4, s5, s12]
The Xona Platform brokers each remote session through a gateway that terminates and isolates OT protocols, so RDP, VNC, SSH, and web sessions reach control-system assets while the user's device never joins the OT network. The Critical System Gateway is the on-site enforcement appliance, and Xona Central Management provides centralized administration across gateways.
Capability has advanced past static access brokering. In March 2026 Xona launched Active Defense, which enforces session controls in real time on detection signals through step-up authentication, suspension, or termination and correlation-driven escalation across events. A Nozomi-certified integration embeds the Arc Endpoint Sensor directly on the Xona Gateway, pairing secure access with OT asset visibility and threat detection as an external validation point. [s1, s5, s6]
Xona competes in OT and ICS secure remote access against direct specialists and adjacent incumbents. Other purpose-built OT remote-access vendors sell the same job to the same buyer, and broader cyber-physical-systems platform vendors that sell asset visibility and threat detection to plant operators sit one purchase away from folding access in.
Its integration partner is also a competitive consideration. The certified Nozomi relationship places Xona next to a vendor the industrial buyer already trusts, but the same buyer relationship gives a broader OT platform a path to bundle access. Pressure also comes from the enterprise IT side, where privileged-access incumbents and zero-trust network-access vendors hold the corporate remote-access budget line and some buyers extend it into OT. [s6, s1]
Xona shows unusually strong named-customer evidence for an OT remote-access specialist. Its homepage and about page display blue-chip operators by name, including GE Vernova, RWE, Baker Hughes, Egyptian LNG, and AltaGas, under a trusted-by banner rather than the unnamed aggregate scale claims that direct rivals lead with.
Partnership and capital signals reinforce the motion. Xona announced a Nozomi-certified integration in February 2025, raised an $18 million strategic round led by Energy Impact Partners in 2024 bringing its disclosed total to $32 million, and shipped two platform releases in early 2026. Independent corroboration now exists beyond the vendor's own pages, since Gartner Peer Insights carries 11 verified reviews of the Xona Platform averaging 4.8 out of 5. The remaining gap is depth, since the named operators still appear as logos rather than as case studies with concrete outcomes in the reviewed sources. [s2, s6, s3, s13]
Founder and CEO Bill Moore is the public voice of Xona in funding and product announcements, supported by a named executive bench that includes a chief financial officer, chief revenue officer, and chief product officer. The company has operated since 2017 and raised across seed, Series A, and a 2024 strategic round.
Public proof of pedigree otherwise stays thin. No founder exit, sustained research-publication record, or recognized community standing in the OT domain surfaced in the reviewed sources, so the team reads as credible and durable but without the external recognition that would lift its profile further. [s8, s7, s3]
Xona builds its pitch around the controls regulated OT audits ask for. The platform states it aligns to NERC CIP, IEC 62443, and TSA requirements and is SOC 2 compliant, and Active Defense answers the response-time gap that auditors and incident responders raise about remote access.
The reviewed sources show a SOC 2 compliance claim on the platform comparison page but did not surface a public trust center or third-party attestation report for Xona as of June 2026, so the SOC 2 posture reads as vendor-stated rather than buyer-verifiable from a published report. This is a gather-time observation, not a categorical absence. [s9, s4]

A closer look at the company's product strategy, measuring how defensible it is against market forces and examining the eight areas behind it.
pivot urgently
Xona is costly to switch but not costly to copy. It deploys gateways at OT sites, so replacing it means re-onboarding identities, policies, and the Nozomi integration, an effortful project rather than a wall, with friction that scales as a buyer covers more sites. What slows a replacement is the buyer class itself, regulated operators under NERC CIP, IEC 62443, and TSA governance demands, though the record documents no specific switching gate. Xona sells software the customer runs, with no managed-service accountability and no patent portfolio or cross-customer data asset in the reviewed record, so a funded rival could build the same gateway. It also sells one job to buyers that broader OT platforms and partner Nozomi already reach, so a customer can cancel without losing a dependency.
| Dimension | Score | Rationale |
|---|---|---|
| Value Delivery Does the product sell software as the product, or judgment, trust, or accountability with software as the delivery mechanism. | 1/3 | Xona sells software the customer deploys and runs, a gateway appliance plus a central management system, and Active Defense is automated session enforcement that is software output. No evidence shows a managed-service layer or the company accepting accountability for customer security outcomes, so the delivered artifact is the product itself. |
| Switching Cost How expensive leaving is for a customer: data portability, integrations, learned workflows, network effects, regulatory data residency. | 2/3 | Replacing an access platform deployed across a buyer's OT sites means re-onboarding identities, policies, gateways, and the Nozomi integration, which is meaningful friction. No cross-customer data gravity adds to it, so migration stays an effortful project rather than a wall. |
| Compliance Moat Whether certifications, liability acceptance, or audit trails block an easy replacement. | 1/3 | NERC CIP, IEC 62443, and TSA mandates drive demand for the category but name no vendor, and the SOC 2 claim is a commercial attestation a determined rival could clear. This is a category tailwind that lifts every qualified vendor rather than a moat that locks in Xona. |
| Problem Complexity Whether the product requires ML, optimization, real-time systems, or years of specialized expertise. | 2/3 | Session brokering with protocol termination across RDP, VNC, SSH, and web is a well-understood access-broker pattern, and Active Defense is policy-driven session enforcement on detection signals. No patented networking mechanism or deep ML is evidenced, so the work reads as solid engineering on an established pattern rather than a technical barrier a competent rival would struggle to cross. |
| Buyer Profile Whether buyers are SMB operators, mid-market IT teams, or regulated enterprises and governments with procurement gates. | 3/3 | Xona sells to regulated industrial enterprises and critical infrastructure operators, with named blue-chip references such as GE Vernova, RWE, Baker Hughes, and AltaGas, operating under NERC CIP, IEC 62443, and TSA demands for demonstrable governance over who accesses critical systems. The reviewed record establishes that buyer class rather than the specific gates such a buyer puts in front of a switch. |
| Layer Whether the product is an end-user application, a platform with application features, or infrastructure other applications depend on. | 1/3 | The platform brokers and enforces remote sessions rather than serving as infrastructure other applications are built on. A buyer can revert to VPNs and jump servers, so nothing depends on Xona as a foundation it cannot replace. |
| Proprietary Data, Content, or IP Whether the product accumulates datasets, content licenses, or IP that a rival cannot recreate from scratch. | 1/3 | The reviewed record shows no patent portfolio and no accumulating cross-customer dataset. Xona brokers and enforces access rather than collecting a corpus that compounds, and a funded rival could build the same gateway and session-control capability, so no proprietary asset appears. |
Xona targets critical-infrastructure operators across energy, electric utilities, oil and gas, manufacturing, maritime, aviation, chemical, and pharma. The named operators on its own site, GE Vernova, RWE, Baker Hughes, Egyptian LNG, and AltaGas, concentrate in energy and oil and gas, which reads as the proven core of a broader addressed market.
The sale runs through two personas at once. Xona pitches OT and operations teams on fast, frictionless access that avoids network reconfiguration, while pitching security and compliance teams on protocol isolation, session enforcement, and audit-ready governance for NERC CIP, IEC 62443, and TSA. Those operator names read as spanning North America, Europe, and the Middle East, an inference from the companies themselves rather than deployment evidence, since the cited pages list customer names without documenting where Xona is deployed. A 2026 joint CISA advisory documents state-linked actors exploiting programmable logic controllers across US critical infrastructure, sharpening the threat case the security persona buys on.
Xona documents a session-brokering architecture. Each session runs through a gateway that terminates and isolates OT protocols across RDP, VNC, SSH, and web interfaces. The user's device never joins the OT network. The Critical System Gateway is the appliance that provides user access to OT assets, and Xona Central Management administers gateways centrally.
Xona introduced Active Defense in March 2026 to stop threats during a live remote-access session, closing the gap between detecting suspicious activity and ending the session. Xona also announced an integration that runs the Nozomi Networks Arc Endpoint Sensor on the Xona Gateway. The sensor discovers critical assets in real time and streamlines onboarding of new assets into the Xona Platform. No proprietary data advantage, patent portfolio, efficacy test, or independent benchmark appears in the reviewed record.
Xona displays blue-chip operators as trusted-by logos on its own homepage and about page, including GE Vernova, RWE, Baker Hughes, Egyptian LNG, and AltaGas. These are vendor-displayed customer references rather than independently corroborated deployments.
Partnership and capital signals reinforce the motion. Xona announced a Nozomi-certified integration in February 2025, raised a 2024 strategic round led by Energy Impact Partners that SecurityWeek reports as $18 million, lifting its disclosed total to $32 million, and kept shipping, with the Platform v5.5 release and the March 2026 introduction of Active Defense as its most recent product news. A Form D filed with the SEC reports a $19,026,905 offering with a first sale on May 28, 2024, covering Series A-1 and A-2 preferred stock plus note conversions, which appears to document the structure of that same 2024 financing rather than capital on top of it.
Independent corroboration exists beyond the vendor's own pages, since Gartner Peer Insights carries 11 ratings of the Xona Platform averaging 4.8 out of 5. The depth gap that remains is that the named operators appear as logos rather than as published case studies with named contacts and concrete outcomes in the reviewed sources.
Xona publishes no pricing on its own site, where the product paths end in demo requests rather than packaging tiers. Its Gartner Peer Insights profile, however, documents the charging model: licensing is primarily per appliance, with each Xona Gateway licensed by capacity and deployment size, plus per-asset and annual-subscription options. That resolves the unit a buyer sizes against, even though list figures stay private.
The opacity that remains fits the motion. Per-appliance and per-asset licensing sold into regulated industrial operators through a demo-led path reads as quote-based enterprise buying rather than metered consumption, an inference from the licensing units and the regulated-OT positioning rather than a documented sales practice. What stays unstated is how a per-appliance and per-asset blend totals across the many sites an industrial footprint spans, which is the number OT buyers use to size the spend.
Xona delivers through gateway appliances administered by a central management system, with flexible cloud or on-premises deployment and a stated 30 minutes per site to stand up, a design that suits the constrained sites it targets. Sessions are session-based rather than network-based, so endpoints never touch the OT network.
Operational integration reaches the surrounding OT stack. The Nozomi-certified integration runs the Arc Endpoint Sensor on the Xona Gateway to discover assets and streamline onboarding, and Active Defense adds ongoing real-time session enforcement rather than one-time deployment. The gateway-plus-central-management model is positioned to scale across distributed industrial footprints.
Xona's trust pitch is compliance-forward. The platform states it aligns to NERC CIP, IEC 62443, and TSA requirements and is SOC 2 compliant, and protocol isolation directly answers the endpoint-exposure concern a remote-access broker raises in an OT environment.
Public trust artifacts about Xona's own controls are thinner. The reviewed sources show a SOC 2 compliance claim on the platform comparison page but did not surface a public trust center or third-party attestation report for Xona itself as of June 2026, so the SOC 2 posture reads as vendor-stated rather than buyer-verifiable from a published report. This is a gather-time observation, not a categorical absence.
Xona positions the platform as the access control plane for OT rather than a point tool, spanning gateway enforcement, central management, and real-time session defense. That breadth moves the company from a single access function toward broader OT access governance spend across a distributed footprint.
The ecosystem play runs through technology alliances. The Nozomi-certified integration is the visible anchor, pairing Xona's access layer with a leading OT visibility platform. That alliance is also a dependency, since the same buyer relationship gives a broader OT platform vendor, now Mitsubishi-owned Nozomi included, a path to bundle access into a wider purchase.
Founder and CEO Bill Moore is the public voice of Xona, supported by a named executive bench that includes a chief financial officer, chief revenue officer, and chief product officer. The company has operated since 2017 and raised across seed, a 2022 DataTribe-led Series A, and a 2024 strategic round, signaling a durable rather than nascent operation.
Public proof of pedigree otherwise stays thin. No founder exit, sustained research-publication record, or recognized community standing in the OT domain surfaced in the reviewed sources, so the team reads as credible and durable but without the external recognition that would lift its profile further.
