A low endpoint rate means little if your technicians still cover nights, investigate alerts and coordinate recovery. For MSP owners, CFOs and IT directors, the useful comparison is not the headline rate but what the service covers and what work stays in-house. Every dollar figure below is a hypothetical U.S.-dollar assumption or calculation, not a published price or market benchmark.

HMI security protects the operator-facing system against unauthorized access, credential misuse, malware, lateral movement and tampering while preserving safe visibility and operational continuity. In PC-based deployments, the OEM-managed application and the Windows or Linux workstation beneath it require separate controls. This guide is for OT and automation engineers, SCADA administrators and plant leaders responsible for HMI availability.

Quick definitionManaged detection and response (MDR) is a managed security service that provides human-led monitoring, investigation and agreed response actions through a remotely operated security operations center.Extended detection and response (XDR) is a technology platform that correlates security telemetry across multiple domains and provides investigation tools and automated response capabilities for security teams.

This October, that journey reaches its most practical phase yet. Acronis Events Acronis Accelerate: Time to act Register now.

OT vulnerability management for Windows and Linux workstations means discovering, assessing, prioritizing and remediating, or deliberately mitigating, software flaws on the general-purpose computers that run supervisory control, historian and engineering functions inside a plant, without disrupting the physical process those computers support. That definition already implies a second, separate layer: the PLCs, RTUs and field devices that this same approach cannot safely touch.

SCADA operations depend on recoverable servers and workstations as well as protected networks and controllers. A failed supervisory host can extend downtime even when field control remains intact. This guide maps the complete SCADA security stack and shows where PC-based backup and recovery fit without presenting Acronis as a SCADA network security platform. For broader OT and ICS foundations, see Acronis' OT and ICS cybersecurity guide.

Australian MSPs have no shortage of technology vendors. The difficult part is deciding which relationships will make the business stronger after the contract is signed. A product can perform well and still create friction if the commercial model is hard to explain, enablement is generic or support disappears when an opportunity becomes complicated. A strong vendor relationship connects technology, operations and go-to-market execution.

This guide is written for controls and automation engineers, OT infrastructure owners and plant leaders responsible for recovering PC-based SCADA systems, including SCADA servers and clients, HMI and engineering workstations, and historians. It does not cover native backup of PLC or RTU logic and firmware; those assets remain within the automation vendor's engineering and lifecycle-management tools. A SCADA server, HMI or historian cannot be recovered like an ordinary IT workload.

With most cyberattacks, the problem announces itself. A service goes down. A user cannot log in. An alert fires. Denial-of-wallet is different. The application keeps working normally while the cost of running it climbs in the background. That is what makes it a security problem and not only a budgeting one. The goal is not to take a system offline. It is to make the system do expensive work that nobody asked for.

For MSPs supporting industrial clients, business leaders responsible for operational risk and OT engineers implementing the standard, IEC 62443 is ultimately about securing OT and ICS environments without undermining availability or safety. Unplanned downtime, legacy systems that cannot be patched, air-gapped facilities with limited or no local IT support, and the need for predictable recovery are the day-to-day realities behind requests to demonstrate IEC 62443 alignment.
