We build the adversary you are allowed to keep.
Nexich is a cyber AI company, founded in 2026 and based in the United States. We make one thing: an autonomous red teaming platform for OT, ICS and SCADA networks, running the full attack chain on hardware you own, without asking you to hand your network over to anyone. It is read-only on the plant floor, because the estates that most need testing are the ones least able to absorb a mistake.
Offensive testing stayed a scheduling problem.
Most organisations learn how they would actually be breached once or twice a year, for a week, from a team that has to be booked months ahead. In between, the network changes every day. The gap between what was tested and what is running is where real incidents live.
Scanners report. Adversaries prove.
A vulnerability list tells you what might be exploitable. It does not tell you whether an attacker can actually chain three ordinary weaknesses into access to the system that would end your quarter. That distance is where security budgets are spent guessing.
An operator that never sleeps.
Software that reasons about the terrain, drives findings toward real access, and stops only when it has proof.
It runs on your metal.
The most sensitive data in an engagement is the engagement itself. We built so that it never has to leave.
Three commitments, enforced in the product.
These are not values on a wall. Each one is a decision that constrains what we are willing to ship.
Your data does not travel.
Air-gapped is the default, not an enterprise upgrade. Run the reasoning on a local model and there is no cloud step in the loop.
No claim without evidence.
In the AI-driven modes a finding is reported only once it has been reproduced. We would rather show you less than show you something we cannot stand behind.
Safe against production, and against a process.
The platform is built to prove access, not to cause damage. Credential replay is rate-limited and lockout-safe. On the plant floor the write function codes are not implementable at all, a short list of channels can never receive a datagram, and every refusal is reported rather than made in silence.
Networks that cannot be handed over.
We build for industrial and critical-infrastructure operators first: manufacturing plants, energy and water utilities, substations, and the building and process estates attached to them. Around that sits everyone with the same constraint, where sending an internal network map to a third party is not an option: regulated industries, defence and public sector, and any security team that has to answer for exactly where its data sits.
The people who own the process network and have to answer for it staying up. They get an assessment that reads controllers rather than writing to them, states its findings by Purdue level, and records what it declined to do next to what it proved.
Teams that want continuous offensive coverage between external engagements, on their own schedule and without an external NDA for every test.
Red teamers who want the mechanical part of an engagement handled so their time goes to the judgement calls software should not be making.
Where things stand.
We are early, and we would rather say so than dress it up. Nexich is a young company with a finished product and a deliberately narrow focus.
Ask us the hard questions first.
We would rather spend an hour on what the platform will not do for you than sell you past it. Tell us what you run and what you are trying to find out.
