Clean result from one of cybersecurity’s most recognized offensive security firms validates Zentry’s operational zero-trust architecture for industrial, federal, and critical infrastructure networks
April 9, 2026, BOULDER, Colo. — FreeWave Technologies today announced that its Elements™ ES1000 connected device with Zentry™ embedded received zero findings in an independent penetration test conducted by Rapid7, one of the most widely recognized names in offensive cybersecurity and vulnerability research.
The result — zero findings across every attack surface tested — is legitimately uncommon in the industry. Recently cited industry average for network and hardware engagements is 5 to 7 findings per engagement, with nearly a third of all tests uncovering at least one critical flaw. In the IIoT and OT hardware space specifically, clean third-party assessments are even rarer: legacy protocol support and hardware constraints force security trade-offs that almost always surface during rigorous testing.
The Elements™ ES1000 with Zentry had none of them.
Zentry Cloaks Your Network
Zentry was purpose-built to make industrial and federal networks invisible to attackers. Where traditional security tools attempt to defend a visible perimeter, Zentry cloaks the network itself eliminating the attack surface before exploitation can begin. Embedded in the Elements™ ES1000, Zentry enforces zero-trust architecture at the device level: no implicit trust, no lateral movement, no exposed management interfaces. Every connection is authenticated, encrypted, and continuously monitored.
Zentry is available embedded in the FreeWave Elements ES1000, as a standalone solution, or deployable on third-party devices giving OT teams, MSPs, and system integrators the flexibility to secure existing infrastructure without a full hardware refresh. The Rapid7 result validates the architecture itself, meaning that validation travels with the solution regardless of deployment path.
“This isn’t a product claim,” said Steve Wulchin, Chairman and CEO at FreeWave Technologies. “This is what happens when a purpose-built zero-trust architecture meets one of the most rigorous independent security assessments in the industry. Zero findings means the attack surface Rapid7 was looking for simply wasn’t there.”
Four Layers. No Gaps.
Zentry’s security posture is built on four integrated layers: hardware root of trust, encrypted communications, identity-based access control, and continuous monitoring. Rapid7’s penetration test probed each of these layers independently and in combination across the Elements™ ES1000 platform. The result validated what FreeWave’s engineering team designed for: a system with no exploitable gaps between layers, no residual exposure from legacy protocol support, and no trade-offs between operational continuity and security integrity.
For OT engineers, that means Zentry secures existing infrastructure without rearchitecting the network. For CISOs and compliance stakeholders, it means independent audit results that directly support CMMC, NIST 800-171, and ICS security framework requirements. For federal and DIB buyers, it means a validated security posture from a firm their own auditors already recognize.
Deploy Without Disruption. Validated.
One of the most persistent objections in OT security procurement is the fear that hardening the network means breaking the operational technology running on it. Zentry was designed to eliminate that trade-off and the Rapid7 assessment confirms the architecture delivers on that promise. The Elements™ ES1000 was tested in conditions that reflect real industrial deployment environments, and the clean result means security teams can present independent validation to leadership, program managers, and compliance auditors without qualification.
Whether Zentry is deployed on the Elements™ ES1000 or integrated into a third-party device, the security architecture is the same. The Rapid7 result validates the solution, not just the hardware.
