Frenos, an AI-native operational technology (OT) security startup, has just secured $1.52 million in seed funding, bringing its total raised capital to $6.4 million. This fresh investment will be used to expand Frenos’ customer success team and fuel the development of its artificial intelligence (AI) research and development.
What’s significant about this funding round is that it comes with the launch of SAIRA Co-Work, an AI reasoning agent designed to provide evidence-based insights during complex investigations. This innovative tool uses machine learning algorithms to analyze vast amounts of data and identify potential security risks in OT systems.
Frenos has built a platform that continuously assesses the security posture of OT systems by creating a digital twin of the customer’s network. SAIRA is then used to run fully simulated penetration tests, validating attack paths, chaining exploits, and prioritizing risks. This approach reduces assessment time to minutes, eliminates downtime impact, requires no additional hardware or scanning, and is risk-free.
The importance of Frenos’ platform cannot be overstated. As Dragos co-founder and CEO Robert M. Lee explains, traditional OT security testing often tells you what’s vulnerable, but not what’s defensible. “The question that matters is what path takes an attacker from an exposed HMI to a process they can actually disrupt,” Lee says. Frenos’ platform addresses this gap by simulating real-world attacks and identifying potential entry points for attackers.
Frenos’ approach has garnered attention in the industry, with Momenta and Exposition Ventures leading the seed funding round, along with additional support from Riptide Ventures. This investment is a testament to the growing recognition of AI-native security solutions as a critical component in protecting OT systems.
The implications of Frenos’ platform are far-reaching. As more organizations rely on connected OT systems, the need for effective security measures has never been greater. By leveraging AI and machine learning algorithms, Frenos’ platform provides a powerful tool for identifying potential security risks and mitigating them before they become major issues.
For readers, this news serves as a reminder of the importance of staying ahead of emerging threats in the OT space. As the industry continues to evolve, it’s essential to invest in solutions that not only identify vulnerabilities but also provide actionable insights on how to address them. By doing so, organizations can ensure their OT systems remain secure and resilient in the face of growing cyber threats.
In practical terms, this means that CISOs and security teams should be looking for AI-native security solutions like Frenos’ platform as a way to enhance their OT security posture. By leveraging machine learning algorithms and simulated penetration testing, these solutions can provide real-time insights into potential security risks and help organizations stay one step ahead of attackers.
