Hiring Your First OT Security Leader: What Should They Own?

Find the work that has no clear owner

Ask the plant, engineering, IT, and security leaders where decisions get stuck. The answer may be vendor access, inconsistent asset records, unclear response responsibilities, or projects that arrive without security involvement. Gather concrete examples. A list of unresolved decisions is more useful than a broad instruction to improve maturity.

Then separate ownership from participation. A plant engineer may already maintain critical equipment records and should remain involved. The new leader might own a consistent inventory approach and the process for resolving missing information. Describe both responsibilities so the hire begins by organizing the work rather than accidentally duplicating it.

Decide who can settle a disagreement

An OT security leader will encounter competing needs. A recommended control may require an outage. A plant may need vendor support at short notice. A corporate standard may not fit a particular system. The hire needs a named executive who can help resolve those conflicts and a documented route for decisions that carry business risk.

That executive is sometimes called the program sponsor. Here, sponsor simply means the senior person who backs the program, helps secure resources, and can bring the necessary leaders together. It should be a real working relationship. A name in an organization chart is little help if the new hire cannot get a decision when work is blocked.

NIST's OT security guidance calls for management support and a team that brings together the relevant operational and technical disciplines. For the hiring brief, make those relationships specific: who attends planning discussions, who approves spending, and who can authorize the operational changes the program needs.

Set a first assignment that can be completed

Consider a company with several plants and different local approaches to remote support. A reasonable first assignment might be to map the existing arrangements, agree ownership with each site, identify the most consequential gaps, and present a sequenced improvement plan with named resources. The scope gives the leader something concrete to investigate and the business something concrete to decide.

Avoid making the first assignment a promise to fix every issue within an arbitrary period. The person may need to uncover conditions nobody has documented. You can still expect visible progress: a reliable account of the current situation, agreement on immediate priorities, and decisions on the people and funding required for the next stage.

Be honest about the resources behind the title

A leadership role with no direct reports can be a strong opportunity if the person has access to engineering teams, outside support, and executive decisions. Describe that operating model. If the hire must personally implement most changes, include that work in the brief and look for someone who wants a substantial hands-on role.

Distinguish an approved team from a hoped-for team. Explain which budget exists, which decisions are pending, and who handles routine work while the program is being established. Candidates can evaluate a developing function when its starting point is clear. They cannot evaluate promises that mean different things to different interviewers.

Interview for how they build working relationships

Ask for an example of a security recommendation that operations initially resisted. Explore what the candidate learned about the process, how they adapted the proposal, who made the final decision, and what happened during implementation. The detail reveals how they work with people who carry different responsibilities.

Also ask what they would need from your leadership team before accepting the position. A thoughtful candidate may ask about plant access, authority, internal support, and how risk decisions are recorded. Those questions help both sides discover whether the organization is ready for the role it wants to hire.
