Discrete and process manufacturers run on MES, PLM, SCADA, and a fast-growing stack of IIoT firmware. ISA/IEC 62443, NIS2, and CISA OT directives turn every shared dependency into an audit obligation across every plant. Safeguard makes that obligation a live, cross-plant query against signed evidence.
OT/IT convergence, IP protection, and cross-plant regulator scrutiny are collapsing into one continuous evidence requirement.
MES, PLM, and shop-floor SCADA are no longer separate islands. They share libraries, share authentication, and increasingly share network paths. A CVE in a shared component can light up the entire plant in one move.
Twenty plants, a dozen MES vendors, hundreds of shop-floor controllers — and no single rollup. Without cross-plant aggregation, the same vulnerable library can sit unpatched in plant A while plant B has already remediated.
Design data, recipe data, and process IP move through CAD plugins, MES integrations, and contract-manufacturer interfaces. A compromised dependency in any of them is an IP loss event, not a CVE event.
Auditors and insurers now expect segmentation that holds against real adversaries, not just network diagrams. Reachability evidence from the SBOM is what closes the gap between policy and posture.
Every build at every plant emits a signed CycloneDX SBOM. Cross-plant rollup surfaces the same vulnerable library across sites, regions, and contract manufacturers in a single queryable view.
Reachability analysis on IIoT and shop-floor firmware distinguishes the library that actually reaches the control bus from the one that ships dormant. Patch windows go to where they earn their downtime.
Every assembly-line software version is attested at build time, hash-pinned, and tied to the SBOM that produced it. Field engineers verify a controller image against its signed bill of materials before flashing.
Shop-floor SaaS — MES, quality, traceability — increasingly runs in vendor cloud. Continuous TPRM with concentration risk surfaces single-point-of-failure components before procurement signs the next renewal.
Pre-mapped control narratives and evidence in the formats your plant auditor and industrial regulator already accept.
Per-plant DMZ control plane, central audit log aggregation, OT-segment-aware policy enforcement, and a vendor trust packet for shop-floor SaaS — all under the manufacturer's control.
Each plant runs a local control plane in its DMZ with one-way data paths to OT. No cross-plant traffic, no shared key material, no shared scanner credentials.
Signed events from every plant stream into a central SIEM in JSON and CycloneDX. Chain-of-custody survives a multi-site audit and a regulator's cross-plant query.
Policy gates respect the plant's OT segmentation model. A library reachable from a corporate API is treated differently from one reachable only from an isolated cell.
Read-only attestation portal for MES, PLM, and shop-floor SaaS vendors. SBOMs, VEX, signed provenance — exposed to procurement and the auditor on demand.
Long-lived PLC and HMI firmware with deep transitive dependencies creates a 10+ year vulnerability tail. Without signed provenance, you cannot tell a benign update from a tampered one.
A single MES vendor compromise touches every plant on the same release. Without cross-plant SBOM rollup, the same vulnerable library can stay unpatched at half the sites for months.
Third-party CAD plugins and PLM integrations are an underrated IP exfiltration vector. A compromised dependency lifts design files before any DLP signature catches the move.
Ransomware targeting shop-floor controllers and MES propagates through trusted update paths. The blast radius is throughput and recipe integrity, not just IT.
Numbers from production deployments inside multi-plant manufacturers. Same vendor stack, same OT, dramatically less spreadsheet.
