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.

OT ransomware is not IT ransomware with an industrial label. An encrypted HMI, engineering workstation, SCADA server or virtualization host can remove operator visibility and force a controlled shutdown even when PLCs continue running. Recovery ends only when operations, engineering, safety and security agree that restored systems and the physical process are trustworthy.

A reliable service desk earns confidence. A trusted business partner earns a place in decisions about risk, growth and continuity. For Australian MSPs, that distinction matters because clients increasingly need more than a list of tools. They need clear advice about which risks to address, which outcomes to prioritise and how technology supports the business. Australian Cyber Security Centre guidance encourages organizations to scrutinize the cybersecurity measures used in outsourced ICT services.

There is no shortage of guidance available to MSPs on how they should secure customer environments. Security frameworks, industry standards, regulatory requirements and insurance obligations all provide recommendations on the controls organizations should have in place. Yet despite this abundance of guidance, cyber incidents remain common and continue to increase. At the same time, requirements are becoming more complex.

Email remains the primary entry point for cyberattacks, making effective email security more critical than ever. That’s why we’re especially proud that customers ranked Acronis Cyber Protect Cloud in the G2 Fall 2026 Cloud Email Security Grid Report. Because G2 rankings are based on verified customer reviews, this recognition reflects the experience of the organizations and service providers that rely on Acronis to protect their users, data and business communications every day.

Security teams rarely lack alerts. The harder problem is working out which ones belong to the same attack — and doing it quickly enough to stop the damage. An endpoint tool may flag suspicious activity on a device. An identity platform may record an unusual sign-in. An email security product may spot a malicious message. When those systems operate separately, each one shows only part of the incident.

Acronis Cyber Protect Cloud has once again earned the highest possible score in AV-TEST’s business Windows endpoint protection evaluation, achieving 18 out of 18 points in the May–June 2026 test. The latest result also extends a consistent record in AV-TEST’s business Windows evaluations. Acronis achieved the same 18/18 result in the February and April 2026 tests, making the May–June evaluation its third consecutive perfect overall score in 2026.

AI DLP (artificial intelligence data loss prevention) is a category of data protection that inspects the prompts and file uploads an employee sends to a generative AI tool, before that content reaches the model, which is what separates it from file-based or network-based DLP.

Shadow AI is the use of generative AI tools by employees without the knowledge, approval or oversight of an organization's IT or security teams.
