About Vantelis

Opscura provides cybersecurity solutions tailored for operational technology (OT) and industrial control systems (ICS). The company focuses on protecting critical infrastructure in sectors such as renewable energy, transportation, manufacturing, government, and chemicals. Opscura's business model centers on providing a drop-in security platform that simplifies the protection of industrial networks, including both modern (greenfield) and legacy (brownfield) assets.

Read full description

Originally founded in Spain as Enigmedia in 2011 by Carlos Tomás and Gerard Vidal, the company rebranded as Opscura and established itself as a global entity with headquarters in the U.S. after a significant funding round in 2023. The founders' journey began with an exploration of melding computer science and physics concepts, which led to the development of their core technology. Carlos Tomás, with a background in electronic and mechanical engineering, leads the engineering initiatives, while Gerard Vidal, an expert in ISO standardization for security mechanisms, heads the technology and research team. In February 2023, Opscura secured $9.4 million in a Series A funding round led by Anzu Partners, with participation from Dreamit and Mundi Ventures, to fuel its expansion into the U.S. market and further develop its product offerings. The company has also received multiple government grants for research into ultra-low latency encryption and industrial data communications.

The company’s core product is a platform that offers OT cloaking, isolation, segmentation, and Zero Trust authentication to protect against risks like ransomware, unauthorized access, and data theft. Its patented cloaking technology is a key feature, designed to obscure OT networks and data at a deep level without causing operational disruption. Opscura's solutions are vendor-agnostic and can be deployed within hours with minimal downtime, a significant benefit for industrial environments that cannot afford to halt operations. The technology is complementary to existing cybersecurity solutions from companies like Claroty, Nozomi, and Fortinet, enhancing threat visibility by providing data from deeper layers of the industrial network. The platform is validated by global partners, including Schneider Electric and Telefonica, and helps organizations meet cybersecurity compliance standards such as IEC-62443.
