Are You in Control of Who is Accessing Your Critical Systems?

Remote access has become essential. However, for most industrial organizations, it’s also become the most dangerous blind spot in their cybersecurity posture. 

The tools many teams still rely on VPNs, jump servers, and shared logins that were never built for today’s OT and IT environments. These legacy systems were designed decades ago, when connectivity was simpler and threats were fewer. 

But today, 88% of industrial sites identify remote access as their most significant cybersecurity risk¹. And attackers know it. 

The Problem: Fragmented Access = Expanding Risk

If you can’t clearly answer who’s accessing what, when, and from where, then you’re exposed unnecessarily. Not just to cyber threats, but to downtime, operational delays, and compliance gaps. 

Legacy tools like VPNs and jump servers introduce serious risk because: 

Real-World Example: What Can Go Wrong?

A natural gas-fired power plant relied on outdated, fragmented remote access tools. User authentication was inconsistent and visibility limited. As a result, unauthorized users were able to access operational systems, triggering major security and compliance concerns. 

The impact? 

After implementing a secure access platform, the plant centralized authentication, enforced role-based access, and gained real-time visibility eliminating blind spots and regaining control. 

The Shift to Modern Access Control

Modern OT and critical infrastructure teams need more than perimeter security; they need access control that is: 

A strong access control framework allows you to: 

Don’t Wait for a Breach to Take Back Control

Most access failures aren’t about firewalls; they’re about trusting the wrong things by default. It’s time to rethink how your teams and partners connect to your most critical systems. 

  1. Evaluate your current remote access policies
  2. Identify gaps in visibility, enforcement, and auditability
  3. Start exploring secure access solutions purpose-built for industrial environments
