The Air Gap Is a Lie: Securing Legacy Water Systems

Industry 4.0 has arrived, bringing critical infrastructure into the internet age whether it was ready or not. You are now managing a complex web of on-premise staff, hybrid employees, and third-party vendors who all need remote access to keep the pumps running. The problem? Industrial machinery that is decades old can’t natively support modern networking features or cyber security best practices.
Using a VPN to secure a HMI, PLC, or SCADA system is like using a screen door on a submarine. It might feel safe, but it won’t hold up under pressure. With government regulations tightening and cyber threats escalating, you cannot afford to rely on porous defenses. Join us to learn how to apply modern identity security to your legacy hardware without ripping and replacing a single controller.
Webinar Highlights
The Speaker
Don Bowman, CEO at Agilicus
Founder and CEO of Agilicus, Don Bowman is an expert in cloud, security, and networking with 30 years of experience in global Internet, technology, public policy.
The days of relying on obscurity for security are over. When you connect a PLC or HMI to the network, you expose infrastructure that was never designed to defend itself. Relying on VPNs or jumpboxes merely extends your perimeter to wherever your vendor is sitting – and that is a risk you cannot control. If they get breached, you get breached. In fact, CISA data shows that nearly 70% of breaches involve valid credentials, meaning the attackers are walking right through the front door.
You do not need to upgrade your hardware to get top of line security. We will show you how to wrap legacy operational technology in a protective layer of multi-factor authentication and single sign-on. This approach allows you to verify the identity of every user, whether it is a specialized contractor or a shift supervisor.
In this session, we will cover:
- Why VPNs and remote desktops are broken models for critical infrastructure defense.
- How to implement Zero Trust access controls that stop lateral movement instantly.
- Practical methods to inject identity-based security into “dumb” legacy devices.
- Strategies to satisfy new government regulations without disrupting your facility’s operations.
