How Shared Vendor Accounts Put OT Uptime and Accountability at Risk

Shared vendor logins feel efficient, but they can obscure accountability and slow recovery when something goes wrong. This blog explores the operational risks of shared accounts and offers practical tips for how to control remote third-party access without disrupting production.

AI Agents in OT: How Shadow AI Creates Operational Security Risk

AI agents may already be operating in OT environments through trusted users, devices, and authenticated sessions. This “shadow AI access” can create operational and security risk, but strong identity and access controls, least privilege, and zero trust can help reduce its impact.

When AI Cyber Threats Evolve Faster Than Critical Infrastructure Can Adapt

AI-enabled cyber threats are evolving faster than critical infrastructure can safely adapt. Following OpenAI’s recent call for collective cyber defense, we examine the implications for OT security and explore how strong identity and access controls can protect legacy and hard-to-patch systems without disrupting essential operations.

How Viridor Gained Visibility, Control, and Speed Across a Distributed OT Environment

The Overlooked OT Security Risks Inside AI Data Centers

TrendAI researchers identified thousands of internet-exposed cyber-physical devices near U.S. data centers. Their findings underscore the importance of securing not just servers and networks but also the operational systems and remote access pathways that keep AI workloads running.

What OT Engineers Actually Want From Remote Vendor Access

A recent Reddit discussion among industrial automation professionals highlights a broader debate about OT remote vendor access and who should control it. The conversation offers a real-world look at different perspectives on secure remote access, vendor access management, and the role of solutions like Cyolo PRO (Privileged Remote Operations).

As AI Compresses the Time to Compromise, We Must Compress the Time to Contain

By making cyberattacks faster, cheaper, and easier to scale, AI is shrinking the time between compromise and impact. This article explores why cyber resilience increasingly depends on security architectures that can contain attacks just as quickly—especially in OT and critical infrastructure.

From Blind Spots to Full Control: The Future of Third-Party Access Security in OT and CPS

What does the future of secure third-party access look like? Rising connectivity demands, emerging AI-powered threats, and evolving operational demands are changing the expectations around secure remote access. Explore new research and analysis from Markets and Markets on the trends that are redefining OT and CPS security.

What the Minnesota Water Attacks Reveal About Securing Remote Access to Critical Infrastructure

Cyberattacks on critical infrastructure don't require advanced exploits. Using the recent Minnesota water attacks as an example, this article explains why strong access controls remain the first line of defense for operational technology and reveals how organizations can reduce their exposure to common attack paths.
