Trustwave launches comprehensive OT security services to fortify industrial environments

Offering bolstered by new partnership with Nozomi Networks 

 July 23, 2025 – Trustwave, a global cybersecurity and managed security services leader has announced the launch of its advanced Operational Technology (OT) services portfolio, designed to empower organisations to defend critical infrastructure and industrial operations against evolving cyber threats. Building upon decades of research, innovation, and hands-on threat intelligence from the acclaimed SpiderLabs team, the new OT services position Trustwave as the partner of choice for enterprises navigating the convergence of IT and OT in today’s complex threat landscape, no matter where they are in their security journey. 

Nozomi Networks, a global authority in OT and Internet of Thing (IoT) security, is a notable new partner in Trustwave’s portfolio. This collaboration fuses Nozomi’s advanced monitoring and analytics capabilities with Trustwave’s managed detection, response, and security expertise, providing unmatched protection for complex and high-risk environments. 

As the convergence of IT and OT accelerates, organisations face unprecedented risks from ransomware, supply chain attacks, and evolving threat actors targeting critical infrastructure. Trustwave’s research highlighted an 80 percent surge in ransomware attacks on the energy and utilities sector, underscoring the urgent need for advanced OT security capabilities. 

Kory Daniels, chief information security officer, Trustwave, said, “It is difficult to protect what you can not see. As technology advances, we have listened to security leaders and observed in the industry how boundaries between OT and IT increasingly are coming together. Industrial control systems, supply chain systems, internet of things, MedTech and many more industries are tackling a diverse technology ecosystem across OT visibility, risk management, defence, and resilience. With this offering, Trustwave is rolling up the sleeves in taking on the OT challenges with the industry by bringing enhanced threat exposure management, detection and response outcomes.” 

As cyber-attacks increasingly target industrial and critical infrastructure—ranging from manufacturing and energy to transportation and maritime—organisations face significant risks to safety, operational continuity, and compliance. Trustwave’s OT services address these challenges with a holistic approach, helping clients: 

• Reduce cyber risk and mitigate disruptive threats through tailored, continuous offensive and defensive security programs. 

• Achieve rapid, actionable visibility across OT assets, networks, and vulnerabilities. 

• Integrate threat intelligence, human-led threat hunting, and world-class incident response into OT-specific monitoring.
