SOC 2 for Precision Contract Manufacturers

Office IT systems get patched, monitored, and access-reviewed the way any modern company's infrastructure would be. Shop-floor OT systems often run on older, sometimes unsupported software because replacing a working CNC controller is expensive and disruptive, and because some equipment simply can't be patched the way a cloud server can. A SOC 2 auditor evaluating your office environment against modern controls, then finding a shop-floor system running unsupported software, needs a clear answer for why that system is scoped the way it is, network-segmented and isolated from the systems actually in scope, rather than an unaddressed gap. Getting that answer wrong, or not having one ready, is a more common finding for manufacturers than any single missing control, since it signals the scoping decision itself wasn't deliberate.

Vanta's broad integration support and standardized templates fit the office IT side of a manufacturer well, design file storage, order management systems, the identity provider staff use, without much custom configuration. Drata's continuous infrastructure testing is useful if the office side runs across multiple cloud environments with automated deployment, less common for a manufacturer than a software company, but increasingly true for firms that have built custom quality management or production planning systems. Secureframe's auditor-assisted model is worth considering specifically for the OT scoping conversation, since getting the network segmentation story right between shop floor and office IT benefits from someone who's navigated that exact question before. None of the three has purpose-built OT evaluation capability, so the choice here mostly comes down to which platform fits the office side best and whether you want direct help with the scoping conversation rather than working it out with a generalist auditor alone.

A general operations manager, who at many manufacturers already owns quality systems and vendor relationships, often ends up as the practical owner of a SOC 2 program even without a security title. The median national wage for general and operations managers is about $105,770¹, a reasonable anchor if you're deciding whether to formalize this into part of an existing operations role rather than hiring a dedicated compliance position, which is rarely justified at this scale until the customer base grows significantly.

It's tempting to scope a SOC 2 audit to the office network and call the shop floor out of scope entirely, especially since compliance platforms are built mainly for cloud and SaaS systems and offer limited native support for OT. This works only if the shop floor genuinely has no path to the data and systems in scope, meaning it's properly network-segmented, not just conceptually separate while actually sharing a flat network. Verify the segmentation technically before asserting it as a scoping boundary; an auditor or a customer's security team that finds an undocumented path between shop floor and office network will treat the whole scoping decision as unreliable, not just that one gap.

Before scoping the shop floor out of a SOC 2 audit, confirm that:

• The shop floor has no path to the data and systems in scope, and the segmentation is technically verified, not just conceptual.
• The segmentation is documented so an auditor can see why OT systems fall outside the boundary.
• Your scoping decision has been discussed with your auditor before the audit starts.
• Customer security reviews, especially in aerospace or defense-adjacent work, are not likely to reach into shop-floor systems.

Manufacturers working with defense-adjacent customers sometimes get asked about ITAR compliance or CMMC alongside SOC 2, and quality-focused customers ask about ISO 9001. ITAR, CMMC and ISO 9001 are each separate frameworks with their own requirements, and only some of the underlying security hygiene overlaps with SOC 2 (CMMC Level 2 is built on NIST SP 800-171, whose access control and audit logging requirements map partly to SOC 2 criteria); in ITAR and CMMC's case there are also legal obligations around export control and controlled unclassified information. Don't let a customer's SOC 2 request stand in for these conversations if your work actually touches that territory.
