Cylentium

What Cylentium does

Cylentium is a private US-based cybersecurity company headquartered in Austin, Texas, that sells a "cyber invisibility" platform aimed at making enterprise, government, and critical infrastructure networks undetectable to unauthorized users. The company employs 51-100 people and operates under the legal entity Cylentium Inc., with Wayne Ronhaar serving as Chief Executive Officer.

The company's core offering is a True Zero Trust SaaS Platform that operates at the Data Link Layer (OSI Layer 2) and sensor Level 0 — described by the company as the first and only platform at this layer. It is built around patented Bubble Cybersecurity Technology, which isolates systems, devices, and users inside secure "digital force field" bubbles, and combines MACsec IEEE 802.1AE Fabric mesh networking with end-to-end encryption that covers both payload and metadata (E2E-EoE). The platform is 100% software and hardware agnostic across Windows, Apple, Linux, Cisco, HP, Nvidia, iOS, and Android, is positioned as FIPS 140-2/3 ready, and includes post-quantum cryptographic capabilities, Policy-Based Access Control with Azure AD connectors, and AI-powered threat detection. Productized service lines extend the platform into Corporate Cybersecurity Services, Government Cybersecurity Solutions, Digital Defense Solutions, and Expert Integration & Training.

Cylentium monetizes through subscription-based SaaS contracts supplemented by professional services for deployment, integration, and training. Distribution is direct: an enterprise field-sales motion targets large corporations, federal/state/local government, and critical infrastructure operators, supported by inside-sales and demo-booking via a toll-free number, email, and a website contact form. Target customer segments include Enterprise/Corporate, Government/Public Sector, Critical Infrastructure, IoT/Level 0 Sensors, and Residential/Home users; no customer logos, pricing, or revenue figures are publicly disclosed.

Direct peers

• Zscaler: Zscaler is the leading pure-play Zero Trust Network Access (ZTNA) and SASE platform, directly competing with Cylentium in policy-driven, identity-based network access for enterprise and government buyers.
• Unisys Stealth: Unisys Stealth offers network cloaking and microsegmentation that renders systems invisible to unauthorized actors — a comparable 'cyber invisibility' architecture operating below traditional network layers, with similar enterprise and federal deployment patterns.
• Cato Networks: Cato Networks is a pure-play SASE platform combining SD-WAN with ZTNA, security, and global private backbone — a direct competitor for enterprise network-centric zero-trust deployments against Cylentium's zero-trust SaaS.
• Guardicore (Akamai): Guardicore provides microsegmentation and zero-trust workload protection, directly comparable to Cylentium's segmentation and 'bubble' isolation concepts; acquired by Akamai, giving it a broader distribution footprint.
• ColorTokens: ColorTokens specializes in zero-trust microsegmentation and asset visibility across data center, cloud, and IoT/OT environments — overlapping with Cylentium's Level 0/sensor and OT/critical-infrastructure targeting.

Broad incumbents

• Palo Alto Networks: Palo Alto Networks delivers Prisma Access ZTNA as part of a broader platform spanning firewalls, SASE, and cloud security — overlapping with Cylentium's zero-trust posture and government/Federal go-to-market but from a much larger incumbent position.
• Cloudflare: Cloudflare Access provides ZTNA and secure web gateway as part of a massive edge-network platform — a comparable zero-trust delivery model but as a feature inside a much broader connectivity, security, and developer platform.
• Cisco (Duo + Secure Access): Cisco bundles Duo and Secure Access ZTNA capabilities alongside its dominant networking hardware franchise, competing for the same enterprise zero-trust budgets as Cylentium while leveraging an enormous installed base.
• Fortinet: Fortinet delivers ZTNA, network segmentation, and OT security across its FortiGate ecosystem — overlapping with Cylentium's policy-based access control and critical-infrastructure value proposition but at vastly greater scale.

Emerging players

• Tempered Networks (acquired by Zscaler): Tempered Networks pioneered 'identity-based microsegmentation' and network cloaking for OT/critical infrastructure — the closest architectural precedent to Cylentium's Bubble Technology — and was acquired by Zscaler, validating both the category and the consolidation dynamic Cylentium could face.
