Milwaukee firms run controllers in other people's plants and payments for other people's banks.
Southeastern Wisconsin sells industrial automation to plants worldwide, runs core and card processing for financial institutions, and writes insurance. Each business holds keys to systems it does not own. Our Milwaukee work tends to start with a list of who outside the company can get in, and how.

In Milwaukee we work with industrial manufacturers, payments and fintech firms, insurers and health systems.
The work covers vendor and remote access into OT networks, machine credentials across bank and processor integrations, identity controls that meet Wisconsin's insurer cybersecurity statute, and governed clinical data. Cohash is based in Frisco, Texas, supports Wisconsin teams remotely and travels in for workshops and launches.
Cohash has no Wisconsin office. Our US headquarters is in Frisco, Texas, so Milwaukee projects run remotely, and we travel to plants, data centers and hospital campuses for discovery workshops, cutovers and launches.

source ↗Who we work with in Milwaukee, and the rules they work under
-
Industrial automation and machinery
Equipment builders support installed machines through remote sessions, cloud dashboards and field service laptops. Those paths reach straight into customer plant networks. We put vendor remote access behind brokered, recorded sessions with per-customer approval, and we give engineering service accounts named owners and rotation schedules.
-
Payments and core banking technology
Processors and core providers hold connections to hundreds of client banks and credit unions, each with its own keys, certificates and file transfer accounts. We inventory those machine identities, map each to a client contract, and move them into a vault so rotation does not depend on one engineer's memory.
-
Life, property and casualty insurance
Insurers domiciled in Wisconsin answer to the state's insurance data security law, which asks for a written program, third-party oversight and a three-business-day notice clock. We build the access reviews, privileged account controls and detection that give the security team its evidence and the speed to meet that clock.
-
Academic medicine and health systems
A teaching hospital mixes clinicians, residents, medical school researchers and students in one identity directory. Research data access tends to outlive the study. We tie access to IRB approvals and credentialing records and scope research warehouse roles per project.
-
Wisconsin breach notification, Wis. Stat. §134.98 ↗
Entities must notify affected people within a reasonable time, not to exceed 45 days after learning of the acquisition. Wisconsin's definition of personal information includes DNA profiles and unique biometric data such as fingerprints and voice prints. Incidents needing 1,000 or more notices also go to the nationwide consumer reporting agencies.
-
Wisconsin insurance data security, Wis. Stat. §601.954 ↗
Created by 2021 Wisconsin Act 73. A licensee notifies the insurance commissioner electronically within 3 business days of determining a cybersecurity event occurred. Wisconsin-domiciled licensees also certify compliance each year by 1 March.
-
FTC Safeguards Rule breach reporting ↗
Covers non-bank financial institutions under FTC jurisdiction, which can include some payments and lending businesses. A breach of unencrypted data on at least 500 consumers goes to the FTC within 30 days of discovery.

01Our service techs need remote access to machines at customer sites. How do we control that?
Route every session through a broker that the customer can see and approve, with recording and a time limit, and retire shared vendor logins. We also help you publish a short access policy for customers, since many plants now ask equipment suppliers for one during purchasing.
02Does Wisconsin's 3-business-day insurer notice apply to us if we're domiciled elsewhere?
It can. Section 601.954 also covers events involving nonpublic information of 250 or more Wisconsin consumers when another notice duty applies or material harm is likely. Confirm with counsel, then make sure your incident runbook can identify affected Wisconsin residents fast.
03Does Wisconsin have a comprehensive consumer privacy law?
Not as of October 2026. A consumer data protection bill, AB 172, cleared an Assembly committee in January 2026 and then failed to pass on 23 March 2026. Your main state duties remain the breach statute and, for insurers, the insurance data security law.
04We run integrations with hundreds of client banks. Where do the credentials go first?
Into an inventory. We scan repositories, file transfer servers and config stores, match each credential to a client, then plan rotation in batches so no bank sees an outage during the move to a vault.
05Can you work on site in Milwaukee?
For workshops, plant walk-throughs and cutover nights, yes. Most design and build happens remotely from Frisco.
