Manufacturing / OT Cybersecurity Assessment

Securing the plant floor takes someone who's actually been on it.

Most cybersecurity people have never touched a PLC or a production line. I've taken manufacturing operations from the plant floor through ERP, so I can secure your OT environment without guessing how it works.

Talk about an OT assessment For manufacturers whose uptime can't be a science experiment.

The problem

Manufacturing security is its own world, and most security consultants are tourists in it. The advice that works for an office network can be actively dangerous on a plant floor: the scan that "just checks for vulnerabilities" can knock a PLC offline and stop production; the patch cycle that's routine for laptops can break a control system that's been running untouched for a decade; the assumption that you can take systems down for maintenance windows collides with a line that's supposed to run 24/7.

So manufacturers get caught between two bad options. Ignore OT security and stay exposed, and increasingly, your customers and insurers won't let you. Or hire a generalist who treats your control network like an IT network and risks taking down production to "secure" it. Meanwhile the real risks, flat networks where office and factory share the same space, remote-access paths left open for vendors, legacy systems nobody dares touch, sit there unaddressed because the person assessing them doesn't understand the environment well enough to fix them safely.

Most security consultants are tourists in it.

What we do

We assess your operational technology the way someone who's lived in it would, because I have. My background runs from the plant floor up: PLCs, manufacturing execution systems, and the full path into ERP. I've been the solution architect connecting the factory to the business systems. So when I look at your environment, I'm not learning what a control system is on your time, I already know how it behaves, what'll break it, and what won't.

That means we can do the thing generalists can't: find and fix the real exposures without putting production at risk. We assess safely, around your operational constraints, not against them. We look at the places that actually matter in an OT environment: how the network is segmented (or isn't), where IT and OT meet, how remote access works, how legacy systems are isolated, how a problem on the business side could reach the factory and vice versa. And we give you a remediation plan that respects uptime: sequenced, realistic, and built for a place that can't just reboot.

What you get

A clear picture of your OT security posture, assessed without disrupting production. The real risks identified and prioritized, segmentation gaps, IT/OT boundary exposures, remote-access paths, legacy-system isolation, in language that makes sense to both your plant people and your executives. And a remediation roadmap sequenced around your operations: what to fix, in what order, without the line going dark to do it.

Who this is for

You run or oversee a manufacturing operation, discrete, process, or somewhere in between. Your customers, your insurer, or your own leadership are asking harder questions about cybersecurity, and you know the office-IT playbook doesn't safely apply to the factory. You've been burned by, or are wary of, consultants who don't understand that downtime isn't an acceptable cost of "security." You want someone who gets both halves: the production reality and the security need.

Engagement

The OT assessment is scoped to your environment and your operational constraints, with the approach agreed up front so there are no surprises on the floor. We'll start with a conversation about how your operation runs.
