Supporting Service · Managed Security & MDR
24/7 OT-aware monitoring, OT SIEM coverage, vendor remote-access oversight, and named incident response capacity for Pacific Northwest data centers, manufacturers, and utilities. We layer specialist OT detection on top of your existing IT MSP/MSSP — so plant-floor signal stops getting drowned out by corporate volume.

What's covered
Passive SPAN-port collection from plant networks. Industrial protocol parsers (Modbus, DNP3, Profinet, EtherNet/IP, OPC-UA). Anomaly detection tuned to the specific traffic patterns of your facility.
Plant logs, BMS supervisor logs, historian access logs, jump-host session logs, OT firewall logs ingested into a dedicated SIEM tenant — separate from your IT signal so OT alerts do not get buried.
Continuous monitoring of every integrator, vendor, and OEM remote-access session. Approval workflows. Session recording review. Anomaly alerts on out-of-window access.
Continuous review of firewall rule effectiveness, allowed traffic patterns, and indicators of east-west movement attempting to cross from corporate IT into OT segments.
EDR coverage on engineering workstations, USB policy enforcement monitoring, project-file integrity tracking, and removable-media event response.
Named senior responder with OT/ICS background. Pre-agreed isolate-or-continue decision tree with your operations lead. On-site response within 4–8 hours for Pacific Northwest facilities.
Monthly working session with your operations and IT leads to review the alert summary, tune detection rules, walk through any incidents, and adjust scope.
Quarterly briefing on OT/ICS threat landscape relevant to your industry — new CISA advisories, vendor CVEs in your stack, sector-specific attack patterns.
Continuous evidence capture (logs, alerts, monthly reports) packaged in audit-ready format for SOC 2, IEC 62443, TSA, and EPA reviews.
How it works alongside your IT MSP
IT MSP/MSSP keeps
Corporate IT, identity, cloud, endpoint EDR, email security, IT SIEM. Your existing relationship, billing, and SOC analyst capacity stay in place.
Cascadia covers
Plant network monitoring, BMS, SCADA, historian, engineering workstations, vendor remote access, IT/OT boundary, and OT-specific incident response.
Both work together when
A finding crosses the IT/OT boundary. We have a documented handoff procedure with your IT MSP — when an event involves both sides, both teams get pulled in within minutes via a single shared bridge call.
Frequently asked
Managed OT security (also called OT MSSP or OT MDR) is ongoing detection, response, and operational oversight of industrial environments — plant networks, BMS, SCADA, and the IT-to-OT boundary. It covers continuous network monitoring, alerting, vendor remote-access supervision, and incident response retained capacity, scoped specifically for OT-aware response constraints.
A standard IT MSSP runs SIEM correlation and SOC analyst response against IT logs and assumes systems can be safely isolated when an alert fires. OT environments cannot be isolated unilaterally — pulling a switchport on a SCADA segment can stop production. Our OT MSSP service includes operations-coordinated response procedures, OT-specific detection rules tuned for industrial protocols, and analysts who know the difference between a normal Modbus poll and an actual reconnaissance attempt.
No — we work alongside it. Most of our clients keep their existing IT MSP/MSSP for corporate networks, cloud, and identity. We layer OT-specific monitoring on top, and coordinate handoff procedures so a finding that crosses the IT/OT boundary gets the right team in the room within minutes.
Plant network span-port traffic, BMS supervisor logs, historian access logs, vendor jump-host session logs, engineering workstation EDR, and the IT/OT boundary firewall logs. We feed the OT-aware data into a dedicated tenant — separate from your IT SIEM — so OT signal does not get drowned out by IT volume.
Critical OT alerts get a named analyst engaged within 15 minutes. On-site response capability for Pacific Northwest facilities is within 4 to 8 hours depending on location. We maintain a documented isolate-or-continue decision tree with your operations team for the most likely scenarios so the response is pre-rehearsed, not improvised.
Yes. Our managed OT security service is regionally focused on Oregon, Washington, and Idaho, with on-site response capability for incidents at Pacific Northwest data centers, manufacturers, and utilities.
