What Goldilock does
Goldilock (legal entity Goldilock Secure Limited) is a UK-based cybersecurity hardware company that provides physical Layer-1 network isolation through its flagship FireBreak™ platform. The product uses patented, non-IP-controlled electromechanical relays inside 12-port RJ45 Ethernet (up to 10 Gbps per port pair) and SFP optical R1200/S1200 (up to 25 Gbps) appliances to physically connect or disconnect network cables on demand, controlled via an out-of-band, non-IP path (SMS with OTP/2FA or RESTful API) so that the protected data path has no IP address, MAC table, or routing logic and therefore no software attack surface. Each port can be configured to fail-open, fail-closed, or return to its last known state, and RJ45 variants ship with dual power supplies. The company complements FireBreak with Connext (a visual blueprint card kit for designing secure network architectures, used by 200+ organisations), FireControl (a co-developed joint solution with Dorado Software that integrates FireBreak into orchestration and automation workflows), and SilentGlass (an NCSC-licensed plug-and-play device, manufactured with Sony UK Technology Centre, that blocks malicious HDMI/DisplayPort connections and is the first commercially available product to carry NCSC branding).

Goldilock product offering
Product offeringCore offering
Goldilock designs, manufactures, and sells patented FireBreak™ hardware appliances (RJ45 12-port and SFP optical R1200/S1200 variants) that physically connect or disconnect network devices at Layer 1 using non-IP-controlled electromechanical relays. Remote control is delivered via out-of-band SMS commands and a RESTful API for SIEM/SOAR integration, with no IP address, MAC table, or routing logic on the protected data path, enabling instant hardware-enforced isolation for critical infrastructure and enterprise networks.
Product overview
Goldilock offers a portfolio of physical-layer cybersecurity solutions centered on its flagship FireBreak™ platform — a patented physical Layer-1 network isolation appliance (also historically branded as Drawbridge / TruAirgap™) that remotely connects or disconnects digital assets using out-of-band, non-IP-based commands. FireBreak™ is the core product, complemented by Connext, a visual blueprint card kit for designing secure FireBreak-enabled architectures, and FireControl, a co-developed joint solution with Dorado Software that fuses Goldilock's physical isolation with Dorado's orchestration platform. A separate product line, SilentGlass, is a plug-and-play HDMI/DisplayPort cybersecurity device developed from NCSC intellectual property, manufactured in partnership with Sony UK Technology Centre and marketed globally under licence. Together these offerings deliver hardware-enforced physical disconnection, segmentation, and isolation across IT, OT, AI/HPC, and critical national infrastructure environments.

Goldilock competitors and assessment
Company assessmentDirect peers
- Waterfall Security Solutions: Waterfall Security Solutions is a direct peer, providing unidirectional security gateways and physical-layer data diodes for industrial control and critical infrastructure networks — the same core "physical isolation between IT and OT" value proposition Goldilock's FireBreak offers, just implemented via unidirectional hardware rather than electromechanical relays.
- Owl Cyber Defense: Owl Cyber Defense is a direct peer producing data diodes and cross-domain solutions that physically isolate networks for defense, intelligence, and critical infrastructure customers. Like Goldilock, it sells hardware-enforced isolation appliances into the same regulatory-driven segments (NATO, CNI, government) and is a like-for-like substitute.
- Illumio: Illumio is a direct peer in network segmentation, offering software-defined microsegmentation that competes head-to-head with FireBreak on the same zero-trust isolation use case. The key contrast — software policy enforcement vs. Goldilock's physical Layer-1 relay-based approach — is the central buy-side decision in this category.
Broad incumbents
- Dragos: Dragos is a broad incumbent in OT/ICS cybersecurity, providing asset discovery, threat detection, and incident response across the same critical-infrastructure verticals (water, oil & gas, rail, manufacturing) that Goldilock targets. It is a more software-led alternative that often competes for the same compliance-driven budget, with a much larger installed base and Series D+ funding.
- Claroty: Claroty is a broad incumbent in industrial cybersecurity, serving the same CNI customers (utilities, manufacturing, oil & gas, healthcare) with a broader portfolio of visibility, vulnerability management, and network protection capabilities. It is one of the most likely software-defined alternatives a buyer would consider alongside Goldilock's hardware approach.
- Nozomi Networks: Nozomi Networks is a broad incumbent in OT and IoT security, providing monitoring, threat detection, and asset visibility across critical infrastructure. It overlaps with Goldilock in the rail, water, energy, and manufacturing segments and is a frequent competitor in CNI RFPs.
- Fortinet: Fortinet is a broad incumbent in network security hardware, offering firewalls, switches, and OT-aware security fabric that overlap conceptually with Goldilock's physical-layer approach. While it does not offer a direct non-IP electromechanical relay substitute, it is a default incumbent in CNI security RFPs and a frequent competing vendor.
- Palo Alto Networks: Palo Alto Networks is a broad incumbent in enterprise and OT cybersecurity (via its Prisma, Cortex, and OT Security portfolios). It offers competing segmentation and zero-trust offerings and is the scale leader with which Goldilock must be compared in enterprise procurement.
- Cisco: Cisco is a broad incumbent in networking and cybersecurity (Secure Firewall, Hypershield, Cyber Vision for OT). Notably, Goldilock's lead US Technical Advisor is Cisco's former SVP & CTO of Advanced Security Research, indicating the strong competitive relevance of Cisco's segmentation roadmap.
Emerging players
- OPSWAT: OPSWAT is an emerging player (post-Bayshore Networks acquisition) in OT network security and data-diode-based isolation, with overlapping critical-infrastructure and defense customers. It provides comparable hardware-enforced segmentation products and competes for similar budgets.
