OT cybersecurity services for plant operators
Hillstrong designs the program and runs it on your sites. Assessments, program design, and managed work. Evidence lands as tasks close. Stepan Company is a customer.
Resilion delivers exactly what cybersecurity leadership and OT teams need: clarity, simplicity, and momentum… it bridges usability with real program execution.
Assessments
What a plant OT risk assessment should produce
IEC 62443-3-2 high-level assessment in three weeks. Zones, conduits, and the exposures worth funding this year. Findings become Resilion tasks.
How a detailed OT risk assessment ranks plant work
Zone-by-zone IEC 62443-3-2 detail for loss of view and loss of control. Ranked work a CapEx decision can use. Every finding becomes a Resilion task.
How mature is your OT security program
Score the OT program against IEC 62443 and NIST CSF. See what exists, what is missing, and what to fund next. Baseline in weeks, not quarters.
Does this plant OT architecture hold
Zones, conduits, and remote access reviewed against IEC 62443-3-3. You leave knowing which paths would take a line down. Findings become Resilion tasks.
Can this plant recover from ransomware
Backup, restore, and decision rights tested against a plant outage. You leave with the gaps that would stop production, ranked for this budget.
Hillstrong serviceWhere IT/OT boundary risk sits this week
Passive capture of real IT/OT traffic for two to four weeks. Modbus, EtherNet/IP, OPC UA, and S7. Findings ranked under the QUICK framework.
Advisory & Program
Design an OT security program you can run
Charter, RACI, and site-tiered work from the assessments you already paid for. Hillstrong designs the program. Resilion keeps the work moving.
Turn OT policy into site-owned work
Policy without owners is a slide. Hillstrong assigns site work, close dates, and evidence. Resilion stores the pack as tasks close.
OT vulnerability management without a patching fantasy
Rank OT vulnerabilities by plant consequence, not CVSS. Compensating controls and change windows. A program your plants can run this year.
Vendor access with an owner and an expiry
Remote vendor access gets an owner, a window, and an expiry. Hillstrong builds the program. Proof lands as access is granted and pulled.
OT cyber advice a CISO can take to the board
Named operators brief the CISO on program status, material risk, and the next funded move. Not a slide deck that dies after the QBR.
Pick OT security tools without buying a second program
Sensors and GRC tools do not run the program. Hillstrong helps you pick OT tools that feed owners, sites, and evidence inside Resilion.
Resilience & Response
OT incident response you can rehearse
Plant IR plan with roles, decision rights, and a tabletop against a real scenario. Gaps become tasks. Evidence is the after-action.
OT disaster recovery that matches the plant
Restore paths, RTO, and who can take the plant down on purpose. Written for operations, not an IT DR binder with OT in the appendix.
Managed Services
Watch the plant without pretending monitoring is the program
Passive OT monitoring at the IT/OT boundary. 24/7 detection ranked by plant impact under QUICK. Alerts become owned work in Resilion.
Stand up an OT security function, then hand it over
Hillstrong staffs the OT security function, runs it on Resilion, and transfers owners to your team. Evidence stays with the program you keep.
Staffing & Training
OT security people on your sites, on your charter
Named practitioners on your sites under your program charter. Work logs in Resilion so the function does not walk out with the contractor.
OT security training operators will sit through
Training built for operators and technicians, not phishing slides. Site rules, vendor access, and what to do when the HMI looks wrong.

Questions plant operators ask
- What OT cybersecurity services does Hillstrong provide?
- Hillstrong designs industrial security programs and runs them on your sites. The catalog covers IEC 62443 and NIST CSF assessments, program design, incident response, monitoring, and staff on the ground. Findings become tasks in Resilion.
- What happens after an OT security assessment?
- The report lists gaps. Hillstrong assigns owners, tiers the work by site, and keeps proof as each task closes. Resilion is the system that keeps that work moving across the fleet.
- Which service should a plant start with?
- Most plants start with a high-level IEC 62443-3-2 risk assessment or an OT security program maturity assessment. Those give leadership a fundable first move.
