Solutions
Protect the assets.
Strengthen the mission.
Security, resilience, governance, and workforce development for the operational technology that federal and public organizations depend on, delivered as one team.
How we work
Assess. Protect. Prepare. Sustain.
Know your risk
Map critical assets and model them in a digital twin to find the exposures that matter most, without touching production.
Close the gaps
Prioritized fixes that reduce risk without disrupting operations.
Train and exercise
Build the skills and plans your team needs to detect, respond, and recover.
Stay ready
Governance, compliance, and refresher training that keep security from drifting.
OT vulnerability assessments
Find the gaps before an adversary does, with no impact to live operations.
With Frenos, we build a digital twin of your OT environment, on premises or in the cloud, and assess it for vulnerabilities and attack paths. Your plant keeps running while we test the model, not the production network.
- Digital twin of your OT network, on premises or in the cloud
- Passive discovery of assets and connections
- Attack path analysis across IT and OT
- Findings prioritized by mission impact
- Clear remediation roadmap
- Repeatable as your environment changes
Asset protection and remediation
Turn findings into fixes that hold up in an operating facility.
We help your engineers and security staff close the highest-risk gaps first, in step with maintenance windows and safety requirements.
- Asset inventory and visibility
- Network segmentation and zone design
- System hardening and secure configuration
- Secure remote access
- Documentation operators and auditors can use
Resilience and readiness planning
Plan for the worst day so you recover fast.
Resilience is more than prevention. We help you prepare for an incident in your control environment and keep critical services running through it.
- OT incident response planning
- Tabletop exercises with operations and IT
- Continuity and recovery planning
- Playbooks built around how your facility actually runs
- Security operations (SOC) build, assessment, and maturity
- SOC analyst and leadership training
Governance, risk, and compliance
CISO-level leadership and practical GRC that hold up to audit.
Our GRC team turns frameworks and regulations into programs people can run, and automates the evidence so your staff is not buried in screenshots.
- vCISO and CISO advisory
- Risk and maturity assessments
- NIST CSF, 800-53, 800-171, and 800-82
- CMMC and FedRAMP
- ISA/IEC 62443 and NERC CIP
- ISO 27001 and the NIST AI RMF
- Policies, charters, and playbooks
- Automated evidence collection
Workforce development
Hands-on training that builds OT defenders on real industrial protocols.
From first-day operators to experienced security teams, our programs are built by people who have created and taught cybersecurity training for DoD and federal agencies.
- Hands-on OT and ICS security training
- Programs for operators, IT staff, and security teams
- Attack, detect, and recover exercises
- Train-the-trainer for internal programs
- Delivered on site or at your event
OT Range: physical OT cyber ranges
A working industrial control system you can train on, safely.
Three standard models, from a deployable case to a full city, all of them customizable and brandable for your organization.
- Deployable case, tabletop plant, and city scale
- Real controllers, protocols, and an operator dashboard
- Built to spec and white-label ready
