Nozomi Networks Unveils Automated Cybersecurity for Critical Infrastructure

In an era where cyber threats loom larger than ever, Nozomi Networks Inc. has made a groundbreaking leap in cybersecurity technology, particularly tailored for operational technology (OT), Internet of Things (IoT), and cyber-physical systems (CPS). On October 28, 2025, the company announced the launch of Nozomi Arc, the industry's first solution to not only detect but also automate threat responses in operational environments.

Evolution of Nozomi Arc

Initially introduced in 2023, Nozomi Arc redefined endpoint security and network monitoring by addressing the unique challenges that OT and IoT environments face. The latest enhancement of Arc introduces robust automated threat prevention capabilities that help industrial organizations protect their mission-critical assets without sacrificing operational efficiency.

Andrea Carcano, Co-founder and Chief Product Officer of Nozomi Networks, emphasized the urgency of this innovation. "Industrial networks are increasingly vulnerable to cyberattacks, and traditional IT security tools are often unsuitable for OT environments," he stated. The advanced features of Nozomi Arc empower organizations to respond to threats proactively and decisively, allowing them to automatically block harmful activities at the endpoint level based on their specific risk considerations.

New Features of Nozomi Arc

The recently launched version of Nozomi Arc boasts flexible automated threat prevention, operational in three distinct modes:
1. Detection Mode: This non-disruptive monitoring option is ideal for organizations focused on audits and compliance, providing essential oversight without impacting operations.
2. Quarantine Mode: This feature identifies and blocks malicious files while enabling forensic analysis, ensuring that threats are addressed while preserving valuable data for investigation.
3. Delete Mode: In critical situations, this option allows for the immediate removal of harmful files, effectively stopping damage in its tracks.

Moreover, the effectiveness of Nozomi Arc is significantly enhanced by its integration with Nozomi Networks' Threat Intelligence and the Threat Intelligence Expansion Pack from Mandiant. This integration allows for real-time indicators of compromise in YARA, STIX, and SIGMA formats, facilitating local behavioral analysis that is indispensable for modern cybersecurity efforts.

Seamless Integration with Existing Systems

What sets Nozomi Arc apart from conventional endpoint solutions is its seamless integration within the existing Nozomi Networks platform. Unlike standalone security agents, this integration allows for streamlined workflows, unifying detection, response, and orchestration activities across an organization’s entire operational technology landscape.

As cyber threats become increasingly sophisticated, particularly with attackers targeting control servers, operator workstations, and other essential OT assets, it is critical that organizations adopt a more proactive and integrated approach to cybersecurity. MITRE ATT&CK® for ICS reveals that a substantial 72% of ICS methods are directed at these vulnerable assets, highlighting the immense vulnerability of many industrial environments.

The Importance of Automated Cybersecurity Measures

By deploying Nozomi Arc's automated endpoint protection, organizations can significantly accelerate their mean time to response (MTTR) while improving visibility across both network and endpoints. This proactive measure not only strengthens security posture but also ensures compliance with industry standards. Rapid threat containment capabilities enable operational teams to maintain productivity with minimal disruption, safeguarding the continuity of essential services.

With Nozomi Networks continuing to innovate and expand its automation capabilities, organizations can expect even more advanced features in the near future, reinforcing the company’s commitment to securing critical infrastructures around the globe. For businesses aiming to enhance their cybersecurity strategies and protect their assets, Nozomi Networks is paving the way toward a safer operational technology environment.
