Specialised OT and IoT security for Operational Technology, Industrial Control Systems, SCADA and connected industrial devices in Singapore and across Asia Pacific. We protect critical infrastructure without disrupting production — safety and availability come first.
In enterprise IT the priority order is confidentiality, integrity, availability. In OT it inverts — an unsafe process state or an unplanned shutdown is the real loss event.
Non-intrusive, passive discovery that builds the inventory you cannot secure without.
A safe testing approach designed around plant reality.
Purdue-aligned zones and conduits that contain an incident instead of letting it spread.
Detection tuned for control networks, integrated with your SOC.
We prioritise the paths that can bridge enterprise systems and production networks — because those are the ones that end in downtime.
Unmanaged or shared remote paths into control networks.
Third-party engineering devices connected directly to plant assets.
IT-side compromise that pivots across a weak IT/OT boundary.
High-privilege hosts able to change control logic.
No segmentation, so one foothold reaches everything.
Typical outcomes when these are left open: unauthorised change, HMI lockout, historian loss, safety review delay, or full plant shutdown.
No response action is taken that could create an unsafe process state.
Actions are agreed with operations and engineering before execution.
Documented fallback so production can continue during containment.
Evidence captured for root cause and regulatory reporting.
Controlled restart with verification at each zone.
OT security protects Operational Technology — the industrial systems that control physical processes such as ICS, SCADA, PLCs and HMIs. Unlike IT cybersecurity, OT prioritises safety and availability first, so controls must avoid disrupting production.
No. Discovery is passive and non-intrusive — we observe traffic rather than scan control devices. Any active testing is scoped with your team and scheduled inside agreed maintenance windows, with compensating controls proposed for systems that cannot be patched.
Yes. Our segmentation and architecture work is aligned to the Purdue reference model with zones and conduits, and assessments map to IEC 62443 practices alongside Singapore CII and OT cybersecurity expectations.
Yes. Where patching is not possible we design compensating controls — network segmentation, protocol allow-listing, strict remote access control and targeted monitoring — so the asset is protected without touching the control logic.
Through governed access paths: jump servers, privileged access management, multi-factor authentication, session recording and time-bound approvals, so vendor connections are controlled and auditable.
Yes. OT and ICS security is delivered from our Singapore HQ for utilities, manufacturing, transport and Critical Information Infrastructure (CII) operators, with regional support across Asia Pacific.
