OT and IoT Security

Protect your most critical assets

Protecting your operational technology is no longer optional—facing outdated systems, limited visibility, and rising cyber threats, businesses need a robust OT security solution to safeguard critical assets and ensure uninterrupted operations.

As industries increasingly adopt automation and smart technologies, securing OT and IoT systems ensures the integrity, availability, and confidentiality of your data and operations. Effective OT and IoT security helps prevent unauthorized access, data breaches, and operational disruptions, which can lead to significant

Implementing a robust OT and IoT security strategy will enhance system reliability, promote regulatory compliance, and build trust among your customers and stakeholders.

Increase Operational Up-Time

Prevent downtime caused by security breaches, ensuring continuous and efficient production and service delivery.

Protect Critical Infrastructure

Strengthen the defences of your essential systems and mitigate the risk of damage, data loss and outages.

Secure IT/OT Convergence

Facilitates secure integration of IT and OT systems, enabling smarter, data-driven decision-making.

Work With The Experts

One of the most common challenges we see businesses face with OT and IoT security is the lack of visibility, making it difficult to monitor and manage a growing number of connected assets—many of which run on outdated or proprietary systems without basic security features. The convergence of IT and OT networks further increases risk, as it broadens the attack surface and introduces vulnerabilities across both environments.

Additionally, inconsistent patching, legacy systems, and a shortage of skilled professionals in OT and IoT security exacerbate the problem. Implementing a comprehensive cybersecurity strategy provides a structured approach to asset discovery, network segmentation, risk assessment, and incident response. This ensures that security policies are standardized, vulnerabilities are regularly assessed and mitigated, and appropriate controls are in place. Ultimately, a well-defined cybersecurity strategy strengthens the overall resilience of OT and IoT environments against evolving threats.

The State of OT Security

Nearly 70%

of industrial firms had an OT cyber-attack last year, this is up from 49% in 2023.

Over 25%

had to shut down operations due to a cyber-attack.

“Industrial organizations need an integrated and cyber resilient IT-OT framework to address this increasingly sophisticated threat landscape”.—Michela Menting, Senior Research Director at ABI Research

Case Studies

Blackmores | OT Security Uplift – Network Segmentation

As their brand and business grew, so did their attack footprint, their existing flat network infrastructure posed several risks. The lack of network segmentation made it hard to isolate sensitive traffic, increasing vulnerability to data breaches, specifically to their OT infrastructure.

Sydney Water | Firewall Implementation to Secure OT Infrastructure

To enhance Sydney Water’s perimeter and internal defences, Sydco implemented next-generation firewalls across its OT network. The objective was to control traffic, enforce security policies, and detect malicious activity without disrupting critical operations.

Lion | OT SOC Implementation

To centralize monitoring and improve response times, Lion Corporate established an OT Security Operations Centre (SOC). This initiative was designed to provide continuous oversight of critical OT assets and infrastructure.

Endeavour Energy | Implementing SIEM & SOC with Splunk for OT Security

Endeavour Energy approached Sydco to implement a Security Information and Event Management (SIEM) system using Splunk, alongside a dedicated OT Security Operations Centre (SOC). The goal was to centralize monitoring, improve threat detection, and enable faster incident response.

Blackmores | 3rd Party Vendor Access Lockdown Via PAM

The company manages sensitive data and critical systems across global operations. As it expanded, securing privileged accounts became a major concern.

Lion | OT Threat Detection with Claroty

To proactively identify and respond to threats within Lion’s OT environment, Sydco deployed Claroty’s Continuous Threat Detection (CTD) platform. This initiative aimed to bridge the visibility gap between IT and OT and enable real-time threat monitoring.
