What we do

Assess, design, and run the program

Start with one engagement or take all three. Each step stands on its own, and each one feeds the next.

  1. 01

    Assess

    Score the program or walk a plant. A maturity assessment takes about six weeks. A plant architecture assessment takes about five, with one to two days on site.

  2. 02

    Design

    Build the charter, decision rights, RACI, and policies your plants will follow, sequenced to your budget cycle.

  3. 03

    Run

    Hillstrong's services can custom build and help you run your program. Choose our platform, Resilion, to route each need to a named owner at a named site and keep the evidence as it closes. Either way, expert help when you need it.

Each sector runs on its own systems and answers to its own rules. Pick yours to see the risks, the standards, and where we start.

the platform

Resilion keeps the work moving across the fleet

Sites feed the program. The program routes tasks to named owners. Evidence lands as the work closes. Resilion stays off the plant network.

We work with the tools you already have

Detection platforms, GRC tools, and assessment reports each cover part of the job. We find the gaps plant by plant and give you the plan to close them.

FAQ

Questions CISOs and plant leaders ask

What is Hillstrong Group Security?
Hillstrong Group Security is an OT cybersecurity consulting firm based in Atlanta. Our practitioners assess plants, design OT security programs, and run them across sites. Clients who want one system to track the work can add Resilion, our platform that routes each fix to a named owner and keeps the evidence.
How is Hillstrong different from OT security product vendors?
We are independent. We do not sell sensors or resell tools, so our recommendations carry no vendor fee. We work alongside the detection platform you already run and focus on the program that closes what it finds.
Do I need Resilion to work with Hillstrong?
No. Our consulting stands on its own. We deliver findings, plans, and reports in the formats your team already uses. Resilion is an option for clients who want every fix tracked to a named owner with the evidence in one place.
Where should a plant start?
Most clients start with an OT security program maturity assessment, about six weeks and run remotely, or a plant architecture assessment, about five weeks with one to two days on site. Both end with a ranked plan and an executive briefing.
Does Resilion connect to live OT systems?
No. Resilion works from your documentation, assessments, and program data. It does not touch control systems and does not require an agent on the plant floor.
