Mike Tisdale Consulting, LLC is a New Hampshire operational technology advisory firm headquartered in Piermont, specializing in industrial OT cybersecurity assessments, legacy PLC and SCADA control system modernization, IT/OT network segmentation strategy, industrial risk remediation roadmapping, and safe digital transformation planning for manufacturing facilities, water/wastewater utilities, energy producers and critical infrastructure operators across New England and the Northeast United States. Our terracotta brand tone represents grounded industrial operational expertise, pragmatic risk mitigation, production-safe system migration planning and resilient OT architecture built to protect continuous process operations. All OT network reviews, control system migration roadmaps, cybersecurity gap assessments and industrial digital transformation strategies developed by Mike Tisdale Consulting align with ISA-62443 standards, NIST industrial security frameworks and owner-operator production continuity requirements. We deliver a comprehensive industrial OT advisory portfolio: OT cybersecurity vulnerability assessments, legacy PLC/SCADA migration planning, IT/OT network segmentation design, industrial firewall architecture, process control change management frameworks, digital transformation feasibility studies, OT incident response planning, and long-term control system lifecycle roadmapping. Our industrial advisory office, OT simulation workspace and administrative headquarters are located at 283 Church St, Piermont, NH 03779, positioned to serve critical infrastructure and manufacturing clients throughout northern New Hampshire, Vermont and western Maine. Our practice draws on deep field experience within process industries, combining control system knowledge with industrial cybersecurity best practices to deliver recommendations that balance security improvements against unplanned production downtime risks. Our standard engagement workflow begins with facility site reconnaissance, inventory of live OT assets, identification of high-risk exposure points, creation of phased remediation roadmaps, technical specification drafting and support through implementation vendor selection. OT and control system strategies from Mike Tisdale Consulting enable asset owners to upgrade aging automation infrastructure and strengthen cybersecurity without unnecessary disruption to continuous industrial operations.
Request OT & Control Systems Advisory Discovery CallMike Tisdale Consulting, LLC is a registered limited liability company operating from 283 Church St, Piermont, NH, US 03779. Founded by an operational technology and industrial control systems subject matter expert with decades of hands-on experience supporting process manufacturing, municipal utilities and energy sector operators across the Northeast United States. Mike Tisdale Consulting LLC was created to address a common industry blind spot: pure IT cybersecurity firms often lack deep understanding of how live PLC, SCADA and DCS control systems function, risking production outages during security upgrades, while automation integrators frequently lack formal industrial security framework expertise. Every advisory engagement begins with respect for production continuity constraints. The practice maintains hands-on familiarity with legacy and modern control hardware, OT communication protocols, industrial firewall operation and the unique uptime demands of continuous process facilities. Each new client engagement opens with asset inventory scoping, stakeholder alignment on acceptable operational risk thresholds and clear definition of facility uptime limitations before developing any migration or security upgrade roadmaps. Inside our Piermont advisory workspace we develop architecture documentation, map OT communication flows and build phased implementation timelines that minimize impact to live production environments. Our core competitive advantage is cross-disciplinary expertise bridging industrial control systems and ISA-62443 cybersecurity, independent unbiased advisory status (no hardware vendor sales incentives), and focus on practical, implementable roadmaps suitable for small to mid-sized industrial and critical infrastructure operators. Competing regional technology firms focus on software development, renewable energy, low voltage installation, embedded navigation hardware or commercial IT integration without deep operational technology and process control domain knowledge. Mike Tisdale Consulting LLC unites OT security risk assessment, legacy control system migration planning, IT/OT segmentation architecture, digital transformation feasibility and industrial incident response planning under one northern New England independent advisory practice. Secure cloud archives preserve all OT asset maps, assessment reports and control system roadmaps for multi-year program sustainment. From our Piermont location advisory support can be mobilized to facility sites across the upper Connecticut River valley and northern New England. We offer three tiered service packages aligned with facility program objectives: Quick Gap Assessment Package – Targeted OT cybersecurity or control system health review to identify highest priority risks; Standard Roadmap Package – Full site OT asset inventory, vulnerability assessment and multi-year phased modernization or security remediation plan; Enterprise Critical Infrastructure Package – Multi-site OT program framework development, cross-facility standards creation, incident response playbook design and ongoing periodic program review support. All OT assessment documentation and architecture deliverables are hosted on United States secure servers.
Live industrial site reconnaissance, OT asset discovery, protocol mapping, vulnerability identification, gap analysis against industrial security standards, and written prioritized remediation reports focused on reducing exposure of PLC, SCADA and DCS control assets to cyber threats.
Conducted full OT asset inventory across multiple treatment facilities, identified unregulated cross-network traffic and developed phased IT/OT segmentation roadmap. Recommendations enabled the utility to implement industrial firewall architecture while maintaining continuous wastewater treatment operations through multi-stage rollout.
Evaluated risks posed by discontinued PLC hardware, compared multiple replacement platform options and created sequenced transition schedule to avoid simultaneous shutdown of parallel production lines. The structured plan provided clear budget and timeline guidance for multi-year capital improvement execution.
Reviewed existing vendor remote support practices, identified unmanaged exposure risks and designed isolated jump-host architecture with session logging controls. The new framework permitted safe third-party control system support while limiting lateral movement threats within the generation OT environment.
