A manufacturer's IT problem is usually an OT problem. Machines on the shop floor run controllers no one wants to patch during a production run, often on operating systems the vendor stopped supporting years ago, and an hour of downtime is measured in lost output rather than lost email.
NIST 800-171 and CMMC where defense work is in the supply chain, ISO 27001 where customers demand it, and segmentation between the business network and the plant floor as a matter of basic practice rather than compliance.
Drawn from the providers ranked on Best IT MSP's Connecticut city listings and filtered to those whose own recorded data names manufacturing. Specialization is never inferred. Entries are deduplicated to one per company and ordered by the same confidence-weighted rating the city listings use. Paid placement is labelled and excluded from the structured data.
28 providers ranked in Connecticut record manufacturing among the industries they serve. Each company is counted once.
Yes. It is drawn from the providers ranked on Best IT MSP's Connecticut city listings, filtered to those whose own data names manufacturing.
NIST 800-171 and CMMC where defense work is in the supply chain, ISO 27001 where customers demand it, and segmentation between the business network and the plant floor as a matter of basic practice rather than compliance.
How do you segment the plant floor from the business network, and can you show it?; What is your approach to machines running unsupported operating systems we cannot replace?; What does your response look like at 2am when a line goes down?
By a confidence-weighted rating that accounts for review volume, so a 5.0 average on four reviews does not outrank a 4.9 on two hundred and fifty. Paid placement is labelled and never mixed into the earned order.
