Fortaegis Technologies has raised an oversubscribed $50 million Series A to move its hardware-rooted cybersecurity architecture from validation into broader commercial deployment, giving the Dutch startup fresh capital to expand in the United States and other major technology markets as AI and autonomous computing create new security demands.

The round was led by returning investor Serendipity Capital. Strategic participants included TEL Venture Capital, the corporate venture arm of Japanese semiconductor-equipment company Tokyo Electron, Dutch research organization TNO and electronics manufacturer Prodrive Technologies. NP-Hard Ventures, NovaCapital, Access Ventures and Coalition Capital also participated, according to Fortaegis.

The financing centers on what Fortaegis calls its Secure Compute architecture, a stack spanning hardware, firmware, cryptography and software. Instead of treating security primarily as a software layer placed above processors and networks, the company uses physical variations created during semiconductor manufacturing to establish chip-level identity and cryptographic trust.

Those minute manufacturing differences make individual pieces of silicon physically distinct. Fortaegis says its architecture can use those characteristics to generate security information dynamically rather than keeping conventional cryptographic keys stored in databases or other locations that attackers could target. The goal is to give servers, edge devices, autonomous systems and other machines a hardware-rooted way to authenticate one another and protect communications.

That model is particularly relevant to the rapid expansion of AI infrastructure. Data centers increasingly link accelerators, servers, storage systems and networking equipment at enormous scale, while AI agents and autonomous machines are expected to communicate and make decisions with less direct human involvement. Each connection can become another point at which identity, authorization and data integrity must be established.

Fortaegis says it has expanded across Europe, the United States and Asia since its inception in October 2023 and is working with more than 25 enterprises and governments. Its target markets include AI infrastructure, semiconductor systems, defense, telecommunications, automotive technology, advanced manufacturing and other critical infrastructure.

The new capital will support production and commercial deployment of Fortaegis’ FPGA-based products across the United States, Europe, Singapore and Japan. Field-programmable gate arrays can be configured after manufacturing, giving companies a way to deploy specialized security functions without immediately committing to a fully custom chip.

Fortaegis also plans to advance its ASIC roadmap. Application-specific integrated circuits are designed for defined workloads and can provide efficiency, performance and cost advantages once volumes justify custom silicon. Moving from FPGA implementations toward ASICs would therefore represent an important step if Fortaegis can convert pilot programs and technical evaluations into large production deployments.

The company says customer-funded development programs and platform selections are already moving from technical validation toward qualification and production. It reports filing 17 patents, with another 14 in development. Fortaegis also says its architecture has demonstrated connection performance more than 200 times faster than conventional approaches in internal and customer testing. That performance figure is a company-reported result and should not be treated as a universal independent benchmark.

Outside organizations have nevertheless examined parts of the underlying security approach. TNO, which became both a strategic partner and investor in Fortaegis in 2025, has worked on formal analysis of the startup’s security protocol and previously described the technology as using each chip’s unique physical fingerprint as the basis for protection. TNO has said the architecture is intended to eliminate the need to store or exchange certain cryptographic keys while supporting secure communications for applications ranging from autonomous vehicles and drones to AI workloads and telecommunications networks.

Fortaegis is also positioning the architecture for a post-quantum computing environment. The company describes its system as quantum-safe by design because its security model does not depend on the same key-exchange mechanisms vulnerable to sufficiently capable future quantum computers. As with other post-quantum security claims, real-world assurance will depend on implementation, independent evaluation and deployment conditions rather than architectural claims alone.

For U.S. technology companies, the financing is notable because Fortaegis is explicitly directing part of its commercialization effort toward the American market. The company says its platform is being deployed with governments, enterprises and strategic technology partners in the U.S., Europe, Singapore and Japan. It has also built a leadership and advisory network spanning semiconductor, national-security and quantum-computing expertise.

The startup’s approach arrives as cybersecurity is moving deeper into the semiconductor stack. Hardware roots of trust are already established concepts across computing, but the proliferation of AI accelerators, connected industrial systems, autonomous devices and specialized processors is raising the stakes around secure device identity. The challenge is no longer only to protect a user logging into a service; increasingly, machines must determine whether other machines, components and workloads can be trusted at speeds that leave little room for manual intervention.

Fortaegis is trying to address that problem with one architecture deployable in multiple forms, including rack-mounted systems, ruggedized edge equipment, compact edge devices and embedded silicon. The company’s commercial proposition is that a common hardware-rooted security layer can extend identity, policy and orchestration across those otherwise fragmented environments.

The Series A also reflects the strategic nature of the semiconductor-security market. Tokyo Electron’s venture arm brings links to one of the world’s largest chip-equipment suppliers, while TNO contributes research and cybersecurity expertise and Prodrive has been working with Fortaegis on industrialization and manufacturing. Serendipity Capital, meanwhile, has investments across quantum technologies and security-focused companies.

Fortaegis founder and CEO Boudewijn Wijnands has framed control over computing infrastructure as both an economic and security issue, arguing that AI and quantum computing increase the urgency of building security directly into foundational infrastructure. The company’s next test will be commercial rather than conceptual: demonstrating that its architecture can be manufactured, integrated and operated economically across the heterogeneous hardware environments used by governments and large enterprises.

If Fortaegis can make that transition, its $50 million round could place the company within a broader shift toward security technologies embedded much closer to the silicon. For Silicon Valley and the wider U.S. technology sector, that shift could influence how future AI clusters, autonomous systems and critical networks establish trust—not only through software credentials, but from the hardware underneath them.
