Find exposed SCADA interfaces and IT vulnerabilities before they shut down production

Manufacturing has been the most-targeted sector for ransomware and intrusion for several years running, and the reason is structural: plants run flat networks, legacy equipment that can't be patched, and an expanding set of internet-facing systems bolted on for remote support and Industry 4.0. The headline risk isn't a hacker directly touching a PLC over the open internet — that's rare. It's the edge that exposes the path inward: VPN concentrators and SSL gateways (Fortinet, Cisco ASA, Ivanti/Pulse, SonicWall) running known-exploited CVEs, exposed RDP and remote-access tools left open for a vendor or a maintenance laptop, and HMI or SCADA web interfaces that someone published to the internet 'temporarily' and never took down.

The second layer is everything that supports the business, not the line. Manufacturers run a sprawl of ERP and MES portals (SAP, Epicor, Infor), EDI and supplier collaboration gateways, customer/dealer portals, and OEM-facing systems exchanging engineering data. These are public web apps with login pages, and they leak the usual way: missing security headers, expired or weakly-configured TLS, exposed .env / .git / config-backup files, and stale subdomains pointing at deprovisioned SaaS that an attacker can claim. The crown-jewel data here — CAD/CAM drawings, BOMs, process recipes, pricing, and contract terms — frequently ends up in misconfigured S3/Azure/GCS buckets shared with a contractor and never locked back down.

The third pattern is acquisition and sprawl. Manufacturers grow by buying plants and product lines, inheriting domains, IP ranges, and shadow IT no one has inventoried. A newly-acquired site brings its own forgotten VPN appliance, its own exposed jump host, its own typosquatted lookalike domains used in invoice-fraud and BEC against AP teams. External scanning is built precisely for this blind spot: it sees what an attacker sees from the public internet across all of those assets. It will not reach the PLCs, drives, or historians sitting behind the firewall — that needs internal/OT tooling — but it reliably finds the internet-facing doors that real-world manufacturing intrusions actually come through.
