TSA
Tabletop Exercises
We help organizations prepare for potential cyber events by testing the team’s understanding,
communication and response strategies in real-time scenarios. Through these exercises, we validate
critical assumptions, assess knowledge and enhance communication between key stakeholders. The
process allows for the identification of gaps, updates response plans and strengthens overall
preparedness, ensuring your team is equipped to handle real-world cyber threats effectively.
TSA Tabletop Exercises
UTSI strengthens critical infrastructure defense by integrating AI-powered simulations into our strategic tabletop exercises. We go beyond theoretical drills to test response plans in real-time, improving coordination without operational downtime. By automating routine analysis and accelerating technical insights, our tools allow your team to focus on high-value strategy—building a smarter, faster, and more resilient cybersecurity program that scales with your enterprise.

Incident response plan
Our cyber security incident response plan service ensures your organization is prepared for cyber events by reviewing existing plans or creating a new response plan if none exists. We ensure every team member understands their roles and responsibilities to improve preparedness and communication. By identifying and closing gaps, we enhance your organization’s ability to respond swiftly and effectively to cyber incidents through OT cybersecurity service.
Cybersecurity framework assessments
Our cybersecurity assessment services concentrate on Attack Surface Management and Incident Response. For attack surface management, we help your organization assess, protect, and manage critical assets. In incident response, we secure your infrastructure by detecting, investigating, and addressing root causes. This ensures fast action to respond, recover, and improve over time. This OT cybersecurity service process strengthens your cybersecurity OT posture and supports long-term resilience.
Regulatory compliance
Our regulatory compliance services ensure sensitive data remains secure through encryption and access controls. We help organizations identify vulnerabilities, develop tailored protection plans, and maintain OT cybersecurity service regulatory compliance management with industry standards. By assessing and addressing compliance gaps, we strengthen your infrastructure and ensure ongoing regulatory compliance, keeping operations safe and secure.
Convergence assessments
A Convergence Assessment looks at IT, OT, and physical security environments together. This approach gives a full view of possible vulnerabilities. Regular assessments can spot gaps that might be missed when areas are reviewed separately. This step is crucial for updating and securing infrastructure and is regarded as a best practice in the field. Our OT cybersecurity service solutions and skilled OT cyber security consultants offer practical insights that improve communication, boost teamwork, and strengthen resilience against threats to critical operations.

FAQS
OT (Operational Technology) cybersecurity focuses on protecting industrial control systems (ICS) that manage physical processes, unlike IT which protects data systems. OT requires continuous uptime and safety, making disruption-free security critical.
UTSI embeds security directly into operations through risk assessments, continuous monitoring, and prevention strategies—ensuring protection without interrupting real-time processes.
Industries such as energy, transportation, water, chemicals, and defense rely heavily on OT systems and benefit from enhanced monitoring, threat prevention, and rapid incident response.
As OT systems become more connected, they face increased cyber threats. Since they control real-world operations, any breach can impact safety, uptime, and compliance—making cybersecurity essential.
This guide breaks down the essential steps and factors you must consider to choose a cybersecurity services provider that truly understands the unique risks of the industrial world.
