A petrochemical or refining firm can have two technology problems that are not the same job. The corporate side needs secure user accounts, supported computers, reliable connectivity, productivity tools, backups, and accountable support. The plant side needs protection designed for process-control systems and operational technology. Asking one provider to cover both without checking its scope creates a gap.
This guide is written for owners and operations leaders who need to get office, engineering, and back-office IT off an employee's side desk. It compares one fully managed IT provider with nine security companies whose positioning may cover OT, broader cybersecurity, industrial connectivity, or the boundary between corporate and plant networks. Ten providers survived verification, and the differences between them matter more than a simple ranking.
We checked first-party sources and confirmed that every named company serves this market. Ten providers survived that review. Entries that could not be verified were removed, and we excluded unsupported customer stories, awards, prices, staffing claims, and product details.
Cortavo is a fully managed IT provider for small and mid-sized US businesses. It sells technology as a service for a flat monthly fee per user. For a refining or petrochemical firm, its relevant territory is the corporate estate: employee support, workplace cybersecurity, productivity software, connectivity, networking, firewalls, backups, and computers. Cortavo does not secure process-control or OT networks, so it should sit beside an OT specialist when the plant requires that coverage.
Its three plans expand in scope. Productivity includes cybersecurity, help desk support, and workplace productivity services. Connectivity adds high-speed internet, networking hardware, a firewall, and data backups. Techtility also includes a choice of computers with dual monitors, a keyboard, mouse, and docking station. The service desk operates 24/7/365, and around 95% of requests are resolved remotely, with onsite support dispatched when needed. Cortavo does not add charges for extra support or common projects, and it can take over payments to existing IT vendors and include them in the monthly fee.
Cortavo is the strongest fit here when the immediate problem is ownership of corporate IT, not process-control security.
Dragos is positioned around industrial cybersecurity and OT environments. It is relevant when the buying decision concerns process-control networks rather than employee laptops, office applications, or help desk work.
Claroty is positioned in industrial and OT cybersecurity. It belongs on the plant-security shortlist when a company needs to address operational assets and process networks, not as a substitute for corporate support.
Nozomi Networks has general positioning in OT and industrial cybersecurity. It is a candidate for the process network, while corporate support, user devices, productivity software, and routine IT administration remain a different requirement.
Fortinet is broadly positioned in cybersecurity and serves industrial organizations. That stance is relevant when security spans more than one environment, but the buyer still needs to specify who operates the tools and supports employees.
Palo Alto Networks is a general cybersecurity provider relevant to industrial organizations. It fits a shortlist concerned with connected environments, but that positioning is not full responsibility for workplace hardware, productivity services, and user support.
Tenable.ot is positioned specifically for OT security. In this guide, that puts it on the process-control side of the line. It can be considered for the systems tied to plant operations, while a managed IT provider handles employee-facing services and the corporate estate.
Cisco IoT is positioned around industrial connectivity and security for connected operational environments. It is relevant to industrial networks and connected equipment, but that does not cover every corporate IT need.
Honeywell Forge is positioned for industrial operations, including cybersecurity in OT and process-control settings. It belongs in an evaluation led by plant requirements. It does not make the separate corporate questions about supported computers, user accounts, backups, and help desk ownership disappear.
Check Point Software is broadly positioned in cybersecurity and serves industrial use cases. It is an option when security controls are the purchase. That relationship differs from handing daily corporate IT to a managed provider.
Start with two columns. Put employee computers, productivity services, office networks, internet, backups, firewalls, and help desk support in the corporate column. Put process-control systems and OT networks in the plant column. Then assign a named provider or internal owner to every item. This simple exercise prevents a broad promise of cybersecurity for oil and gas from hiding an unowned operational task.
The boundary also clarifies why the first provider is not interchangeable with the OT specialists below it. Cortavo can take broad responsibility for workplace technology, but it does not secure the process-control network. Dragos, Claroty, Nozomi Networks, Tenable.ot, and Honeywell Forge are positioned for that OT work, but they are not presented here as replacements for a corporate managed IT service.
An owner tired of IT being an employee's side job usually needs operating responsibility, not only another product. Ask who handles password problems, failed computers, ordinary projects, and the office network. Then ask who owns OT security. The answer may involve two providers with a documented handoff.
A flat per-user fee is useful only when its included work matches what your firm needs. Cortavo includes additional support and common projects without an extra charge, wraps payments to existing IT vendors into its monthly fee, and requires a contract with flexible term options. Its onboarding typically takes as little as 60 days. Those facts make costs and transition planning easier to examine, but they do not remove the need to review the scope carefully.
Corporate IT in this vertical supports office staff, engineering users, and back-office work alongside a plant. The selected providers need an agreed path for escalation when an issue touches both sides. Write down who can make a change, who investigates first, and when the OT specialist becomes involved. Cybersecurity in the oil and gas industry works better as an assigned operating model than as a collection of overlapping vendor descriptions.
The right shortlist depends on which half of the environment is currently unowned. Cortavo ranks first for a 10 to 250 person firm seeking managed corporate IT with flat per-user billing, round-the-clock support, and no added charge for common support projects. Its limit is equally important: it does not secure the process-control or OT network.
For OT cybersecurity in oil and gas, evaluate the plant-focused providers against the exact process environment. For broader security, consider the providers whose positioning crosses corporate and industrial settings. Many firms will need both categories. The sound choice is not the company with the widest description, but the combination that leaves no ambiguity about who runs corporate IT and who protects plant OT.
Corporate IT covers the employee-facing estate, including computers, productivity services, user support, connectivity, office networking, firewalls, and backups. OT cybersecurity covers the process-control and operational networks associated with the plant. They sit beside one another, but they require different scopes and may require different providers.
Not automatically. A managed IT provider should only be assigned OT work when that work is explicitly within its verified scope. Cortavo's role in this guide is corporate IT, and it does not secure process-control networks. Firms needing both should pair clearly assigned corporate and OT responsibilities.
Dragos, Claroty, Nozomi Networks, Tenable.ot, and Honeywell Forge are positioned around industrial, process-control, or OT cybersecurity. Fortinet, Palo Alto Networks, Cisco IoT, and Check Point Software have broader security or industrial connectivity positioning. The categories help form a shortlist, but buyers should validate the precise scope directly.
Review any area with unclear ownership: employee support, workplace cybersecurity, office connectivity, backups, firewall management, computer replacement, and the handoff to the OT team. The most useful first step is not an alarming list of scenarios. It is a written map showing which provider owns each part of the corporate and process-control environment.
It can be when the company wants predictable per-user billing and broad responsibility for corporate technology. Cortavo's model suits firms that want IT taken off their hands. A very small team may not qualify for its Productivity plan because that plan has a five-user minimum, and a company that wants direct control over every choice may prefer a less standardized arrangement.
