ICS/OT Security

Maintain integrity, safety, and uptime across your cyber-physical systems

Ensure resilient critical operations

By compromising ICS/OT operations, sophisticated cybercriminals can cause significant damage – from shutdowns, equipment damage, and health and safety risks to the loss of financial assets, reputation, intellectual property, and competitive advantage. With Trend Micro, you have visibility into threats affecting ICS/OT through IT and CT, plus enhanced detection and response.


Unified platform for OT, CT and IT

Ensures enhanced prevention and detection, as well as the resilience of critical operations, with global, purpose-built OT, CT(5G), IT, and extended detection and response (XDR) security solutions and professional services.


Risk and threat visibility

By sending data to a security platform, our interconnected solutions give you complete visibility with risk insights, detect and investigate threats faster, and respond better across the entire environment.


Protecting legacy and modern systems

Protect programmable logic controllers (PLCs), human-machine interfaces (HMIs), robots, legacy and modern OSes, edge devices, hybrid cloud environments, industrial networks, and private 5G networks.

Use cases

Protect your infrastructure with an integrated approach

Manufacturing expand_more


To keep pace with today's digital transformation, protecting factory environments – from traditional devices to state-of-the-art infrastructures – is crucial.

Hospital expand_more


Ransomware attacks have increased in the healthcare sector over the past few years and present a threat to PHI, hospital operations, and patients. Consistent security in a heterogeneous environment is a must.

Oil and gas expand_more

Oil and gas

As the entire operating systems of oil and gas companies are online and connected to the Internet of Things (IoT), their vulnerability to cyber attacks increase exponentially.

Oil and Gas
Electric utility expand_more

Electric utility

As electric utilities are digitalizing operations, they face increased cyberattacks. Authorities have tightened regulations, requiring enhanced security controls, incident response for the entire environment, and prompt incident reports.

Electric utility

Protection for key operational areas

Unravel the complexity – no matter the environment

Defend your IT/OT perimeter

Establish a boundary of defense between the corporate network and the factory base, or between the office and the field area



Preventing malware infection on servers in the internal DMZ

  • All-in-one hybrid cloud protection without compromising performance

Preventing vulnerability attacks from the IT to the OT environment

  • Inline deployment between IT and OT networks prevents vulnerability attacks at wire speed

Protect your OT assets

Protect industrial endpoints that are difficult to patch or install security software on



Securing legacy devices/OSes without impacting system performance

  • Protects legacy devices by system lockdown or application control

Protecting software-installation prohibited devices or recovering infected devices

  • Provides malware scanning and cleanup on the device without software installation

Preventing critical assets from vulnerability attacks without impacting system availability in the existing environment

  • Transparent network security for critical assets enables firewall, protocol filter, and IPS protects against vulnerabilities without changing logical network configuration

Secure your OT network

Network security adapted to the industrial protocol used in field networks



Segregating flat networks without impacting system availability in an existing environment

  • Transparent network security for the uplink port of existing L2 switches enables a firewall and protocol filter without changing logical network configurations

Building secure network segments by default

  • Ensures network segments by network address translation (NAT), firewall, protocol filter, and IPS functions

Low visibility and identification of IT/OT network protocols on a shop floor

  • Deep packet inspection improves situational awareness by inline deployment or passive monitoring

Anomaly behaviors in level-3 to level-5 networks

  • Detect anomaly behaviors by connecting them with a mirror port of network switches

Ensure secure offline operations

Secure removable media and brought-in devices during maintenance



Malware infection via USB storages brought into the OT environment

  • Trend Micro Apex One™, an all-in-one endpoint security, ensures USBs brought by third-party engineers into the factory are safe to use
  • TXOne Portable Inspector Pro Edition, a secure transporter, offers 64 GB of secure USB storage for repeat use in a shop floor by scanning and encrypting all files stored

Ensuring cyber hygiene of outside laptops and machines brought into the OT environment

  • Scan devices before they are brought into the OT environment without installing software

Protect IIoT devices, cloud and networks

Secure the use of new technologies – industrial clouds, private 5G, IoT sensors, and more



Protecting modern devices/OSes without impacting system performance

  • Protects modern devices via ICS purpose-built next generation malware prevention software

Resolving cloud environment misconfigurations

  • Monitors, improves, and remediates automatically the security and compliance posture of your cloud environment

Preventing threat intrusions from IoT gateways on a shop floor

  • Transparent network security for the IoT gateway that prevents unauthorized access and vulnerability attacks

Preventing unauthorized access, malware infection, and spread in private 5G networks

  • Prevents illegitimate device attachment and vulnerability attacks and recognizes malicious content and suspicious network behaviors at the data network

Empower your SOC / CSIRT

Streamline response with integrated monitoring of your entire environment



Alert fatigue caused by disconnected point solutions

  • Bridging the gap between OT and IT with centralized visibility by collecting and correlating deep activity data across multiple vectors. Security teams have the ability to detect faster, investigate more thoroughly, and respond more efficiently

Why Trend

Keep operations running with minimal TCO through support at all phases – prevention, detection, and response – over a long period of time.

OT, CT, and IT-integrated threat intelligence and solutions

Reduce monitoring complexity and operating costs, empowering your CISO and security operation teams. Fueled by vulnerabilities research from Trend Micro Zero Day Initiative, future threats predictions by Trend Research, and ICS/OT expertise brought by TXOne Networks, our solutions bring more precise and early detection and response.

Single vendor, global support

Using multiple vendors' products is not efficient – it creates complexity and requires a lot of time to evaluate products, create SOP, and establish a support scheme.

Deploy a single solution, utilize single SOP worldwide, and respond quickly and smoothly to incidents, ensuring stable operations and minimal TCO.


As a trusted company with 30+ years of experience, Trend has a strong financial base, sustainable high profitability, and the robust cybersecurity offering required to protect customers in private and public sectors.

Strategic partners
