Network Automation for Manufacturing: Keeping OT and IT Networks Running Without Inbound Access
Plant networks are unforgiving in a specific way: downtime stops production within minutes, the site IT team is usually one or two people, and nobody wants another inbound path into the OT side of the environment. OrcaMonitor connects outbound-only, correlates alerts across switches, firewalls and links, and gates every change so production is never touched by an unapproved fix.
Problems we solve
- Production stopped by a network fault that takes too long to localise
- Site IT teams of one or two covering plant, office and WAN
- Security teams blocking new inbound monitoring connections into OT
- Maintenance windows that leave no time to debug, only to apply a change
- Vendor and integrator changes on the plant network with no record
Built for plant and OT constraints
- Outbound-only secure connect — no inbound OT firewall rules
- Root-cause correlation across switches, firewalls and links
- Approval-gated changes with blast radius and rollback
- Config backup and drift detection against undocumented changes
- Works across mixed vendor equipment on one plant network
Capabilities
No inbound path into OT
The secure connect agent dials outbound only, so typical deployments need no inbound firewall rules — the objection that most often stops an OT monitoring project before it starts.
Localise faults fast
Correlate alarms across access switches, plant firewalls and WAN links so the team sees the failing segment first, instead of walking the floor with a laptop while the line is down.
Change windows, enforced
Proposed changes carry their blast radius and rollback, and nothing executes without approval — so an out-of-window or unreviewed change on the plant network is a deliberate, recorded act rather than an accident.
Coverage for lean site teams
Config backup, drift detection and IPsec diagnosis for FortiGate, Cisco, Juniper, Palo Alto, Arista and MikroTik keep a small team able to operate equipment it did not originally standardise on.

FAQ
Can you monitor an OT network without opening inbound firewall ports?
Yes. The secure connect agent initiates an outbound-only encrypted connection to the platform, so in typical setups no inbound ports are opened from the internet into the OT network. That keeps the project out of the change board conversation that usually stalls OT monitoring.
Does OrcaMonitor change devices on the OT network automatically?
No change happens without approval. The AI proposes a specific remediation with its blast radius and rollback and an operator approves it, which means a production device is never altered by an unreviewed autonomous action.
How does this help a site with only one IT person?
By concatenating the jobs that person cannot specialise in: device discovery, config backup, drift detection and IPsec diagnosis are built in for FortiGate, Cisco, Juniper, Palo Alto, Arista and MikroTik, and alert correlation removes the need to triage a wall of alarms before knowing where to look.
Can maintenance windows be enforced?
Approval gating is the mechanism. A change is proposed and reviewed before it runs, so applying an unreviewed fix during production hours becomes a deliberate decision with a name attached rather than something that happens because an engineer was moving fast.
Does it work with mixed vendor equipment on a plant network?
Yes. The platform is vendor-neutral and covers FortiGate, Cisco, Juniper, Palo Alto, Arista and MikroTik, which is the practical case for plants assembled over years from whatever the integrator specified at the time.
