Tel Aviv-based startup Prisma Photonics has raised $30 million in a fresh funding round to boost its optical fiber sensing technology for monitoring critical infrastructure. Announced on October 15, 2025, the investment comes amid growing global needs for better security and grid protection against threats like extreme weather and physical damage.
This round, led by Israeli defense tech fund Protego Ventures, highlights the startup’s role in turning everyday optical fibers into smart monitoring tools. With this capital, Prisma Photonics plans to scale its AI-driven platform that detects issues in real time across power grids, pipelines, and secure borders.
Company Background and Technology
Prisma Photonics started in 2017, founded by electrical engineer Eran Inbar. The company focuses on innovative ways to use existing optical fiber networks for surveillance without adding new sensors.
Their hyper-scan technology sends light pulses through fibers to pick up vibrations and changes. This creates a continuous acoustic sensing system that spots problems over long distances, up to thousands of kilometers.
The platform uses machine learning and algorithms to classify threats. It can identify wildfires, ice buildup, strong winds, or even tampering with infrastructure.
In recent years, events like the 2023 Gaza border issues and global cyber threats have pushed demand for such tech. Prisma Photonics has deployed its systems in the US, Europe, and Israel, helping utilities respond quickly to dangers.
Experts say this approach cuts costs and boosts efficiency. Traditional methods often need expensive hardware, but Prisma’s solution leverages what’s already there.
Details of the Funding Round
The $30 million growth round drew interest from key players in energy and tech. Protego Ventures took the lead, with Adara Ventures and a major Latin American transmission operator joining in.
Existing backers like Insight Partners, Chione Switzerland, and Schneider Electric’s SE Ventures also pitched in. This brings the total funding for Prisma Photonics to around $80 million since its start.
Protego Ventures, launched after the 2023 Hamas attacks, focuses on defense tech. Its managing partner praised Prisma for turning fibers into powerful monitoring systems that address security and resilience needs.
The funds will help expand operations and refine AI features. Inbar, the CEO, noted that the tech can switch from protecting military sites to aiding renewable energy setups.

Impact on Critical Infrastructure
Critical infrastructure faces more risks today from climate change and security threats. Prisma’s technology offers a timely fix by providing real-time alerts without extra equipment.
For power grids, it detects overloads or damage from storms. In security, it monitors borders and perimeters for intrusions.
One example is its use in spotting wildfires along power lines. This helps prevent outages that affect millions, like those seen in recent US and European events.
The platform also supports the shift to green energy. By optimizing grid performance, it aids integration of solar and wind power, key in 2025’s push for net-zero goals.
Industry analysts predict growth in fiber sensing markets. With rising investments in smart grids, companies like Prisma stand to gain.
Market Trends and Future Outlook
The optical fiber sensing sector is booming. Global markets expect to reach billions by 2030, driven by needs in energy and defense.
Prisma Photonics fits into this trend with its AI edge. Competitors focus on similar tech, but Prisma’s sensor-free method sets it apart.
Recent events, such as 2024’s infrastructure attacks in Europe, underline the need. Governments are funding more projects for resilient systems.
Looking ahead, Prisma aims to enter new markets in Asia and Latin America. Partnerships with energy firms could speed up adoption.
Experts believe this funding will fuel innovation. It positions Prisma as a leader in protecting vital assets against modern threats.
- Key benefits of Prisma’s technology: Real-time threat detection, no new sensors needed, covers vast areas efficiently.
- Potential applications: Power utilities, oil pipelines, military borders, renewable energy optimization.
