Manufacturing Security That Works With Your Reality

It depends on the SIEM. Blumira monitors the IT side of manufacturing environments: cloud platforms, identity providers, endpoints, firewalls, and business applications. It does not natively monitor OT protocols like Modbus, BACnet, or EtherNet/IP. For organizations that need visibility into programmable logic controllers (PLCs), SCADA systems, or industrial IoT devices, a dedicated OT monitoring tool like Claroty, Dragos, or Nozomi Networks is the right choice. Blumira protects the IT infrastructure that connects to and controls the OT environment, which is where most manufacturing cyberattacks originate.

NIST SP 800-171 is required for manufacturers in the Department of Defense supply chain, and CMMC 2.0 is the certification framework that enforces it. NIST CSF (Cybersecurity Framework) is widely adopted voluntarily across all manufacturing sectors. Both frameworks require continuous monitoring, audit logging, and incident response capabilities. Blumira maps its detections and compliance reporting to NIST 800-171, CMMC 2.0, and NIST CSF controls, and provides 1 year of searchable log retention to satisfy audit requirements.

Most manufacturers run IT teams of 2 to 5 people responsible for everything from help desk to production floor networking. Blumira is built for exactly this situation. Detection rules are written and maintained by Blumira's 24/7 SecOps team, so your IT staff does not need security engineering expertise. Alerts come with guided response playbooks, and automated response actions can contain threats without waiting for human intervention. The platform deploys in a single afternoon and connects to existing infrastructure through pre-built integrations. Manufacturers without dedicated security staff can also deploy Blumira through a managed service provider (MSP).

Manufacturing was the most targeted industry for cyberattacks in 2023 for the third consecutive year, according to IBM X-Force's 2024 Threat Intelligence Index. Attackers target manufacturers because production downtime creates immediate financial pressure to pay ransoms. Common attack vectors include phishing emails, compromised remote access tools (especially VPNs and RDP), and supply chain software vulnerabilities. Blumira detects the precursors to these attacks, including credential theft, lateral movement across networks, privilege escalation, and data staging for exfiltration, and automated response actions can contain the threat before it reaches production systems.

Large manufacturers and defense contractors increasingly require their suppliers to demonstrate cybersecurity controls as a condition of doing business. CMMC 2.0 formalizes this for the DOD supply chain, but private-sector primes like Boeing, Lockheed Martin, and automotive OEMs have similar expectations. A SIEM provides the continuous monitoring, audit logging, and incident detection that supply chain assessors look for. Blumira's compliance reporting maps to NIST 800-171 and CMMC controls, and 1 year of searchable log retention provides the audit trail that assessors require.

Blumira monitors the IT systems present in both environments: firewalls, switches, Windows servers, endpoints, cloud platforms, and identity providers. If your production floor uses standard IT networking equipment that forwards syslog or integrates via API, Blumira can ingest those logs. However, Blumira does not decode or inspect OT-specific protocols used by industrial control systems. The recommended approach for converged OT/IT environments is to pair Blumira for IT-layer detection with an OT-specific monitoring tool for protocol-level ICS visibility.

Blumira is not the right fit if your primary need is native OT protocol monitoring, deep packet inspection of industrial control system traffic, or asset inventory of PLCs and SCADA controllers. Those requirements call for a dedicated OT security platform. Blumira is also less customizable than enterprise SIEMs like Splunk, so manufacturers with large security teams that want to write custom correlation rules and build bespoke dashboards may prefer a platform that offers in-platform query languages. For manufacturers with small IT teams focused on meeting compliance requirements and stopping ransomware before it hits production, Blumira is purpose-built.
