Security teams rarely struggle to collect enough alerts. The harder job is deciding which device deserves attention first, understanding what it is communicating, and turning that evidence into an action that does not disrupt business operations.
That challenge gets more complicated in mixed IT and operational technology (OT) environments. Servers, workstations, cameras, printers, medical devices and industrial controllers do not all behave alike, and many cannot be treated like a standard employee laptop. Network visibility becomes an important part of the picture.
Start with the device that is becoming risky
GREYCORTEX Mendel 5.0 introduces a device risk score based on security events and how unusual a device’s behaviour is compared with other devices on the same network. The score is tracked over time, so analysts can see whether a host is becoming riskier rather than treating every alert as an isolated event.
That historical view can help a small security team prioritise investigation. A device whose score is climbing may deserve a closer look than a host that has generated the same low-level noise for weeks. It is still a triage signal, not an automatic incident verdict: teams should validate the score against asset criticality, maintenance windows and what the system is meant to do.
Follow the traffic to understand the context
Once a device looks unusual, the next question is what it is talking to. Mendel 5.0’s Traffic Flow Map puts a host and its significant communication partners into one view. Analysts can inspect connections using measures such as flows, packets, data volume, retransmissions and unreplied flows, then move from one device to another without leaving the map.
For an IT/OT environment, that context matters. A workstation suddenly communicating with an unfamiliar server is one kind of investigation; a controller exchanging traffic with an approved engineering station during a planned maintenance window is another. A visual path through the connections helps the analyst ask better questions before escalating or blocking traffic.
Use AI assistance to speed up the first pass
Mendel 5.0 also adds an AI Assistant that explains devices, IP addresses and security events in plain language. GREYCORTEX says it can identify likely device roles, assess external IP addresses, explain an event, estimate whether it may be a false positive and suggest investigation steps in priority order.
That can make technical findings easier to hand over to an operations colleague or manager who does not spend all day reading network telemetry. Treat the assistant as decision support, though. Confirm its interpretation with packet evidence, asset records and the people responsible for the affected process—especially before taking action on production OT equipment.
Why this is relevant to Singapore operators
Singapore’s Cyber Security Agency has been putting greater emphasis on visibility and readiness for critical infrastructure. In a July 2026 speech, Minister Josephine Teo described the priorities as “lock down, find first, and fix fast”, and highlighted the difficulty of seeing what is happening inside many OT environments. CSA’s updated Cybersecurity Code of Practice for Critical Information Infrastructure was issued on 29 July 2026.
For organisations that operate or support essential services, the practical takeaway is straightforward: do not assess network detection only by the number of alerts it generates. Ask whether it helps your team discover unfamiliar assets, understand communications between connected systems, investigate unusual behaviour and coordinate a safe response. The same discipline is useful for manufacturers, logistics operators, healthcare groups and other businesses with connected facilities, even when they are not designated CII owners.
A practical evaluation checklist
- Coverage: Confirm which network segments, sites, VLANs and OT zones can be monitored, and identify any blind spots.
- Asset context: Check how the platform identifies devices and how teams can correct or enrich asset details.
- Prioritisation: Ask how risk scores are calculated, what changes them and how analysts can review score history.
- Investigation: Test whether traffic maps help analysts trace a device’s communication path and distinguish normal operational traffic from suspicious activity.
- Response: Agree who can approve containment or blocking actions, and how IT and OT teams will coordinate during an incident.
- Deployment and data handling: GREYCORTEX says Mendel runs on-premises, including in fully air-gapped deployments; its AI processing runs within EU infrastructure and can be disabled. Singapore buyers should validate telemetry flows, data handling and AI settings against internal policy before deployment.
Make the investigation workflow the measure of success
A network detection platform should do more than add another console to the security stack. The useful test is whether it helps an analyst move from “something looks odd” to “this is the device, this is its communication path, this is why it matters, and this is the next safe step”.
Mendel 5.0’s risk scoring, Traffic Flow Map and AI Assistant are designed around that workflow. Singapore IT and OT teams evaluating the platform should test those capabilities with representative traffic and real operational scenarios, then measure investigation time, false-positive handling and the quality of evidence they can hand to incident responders.
