A Reflection on Freedom in OT

As we leave behind the Fourth of July, my thoughts, like many of yours, have been about appreciating freedom (even if you are not from the US, freedom is pretty darn important these days). Barbecues, fireworks, and time with family and friends are all part of celebrating the independence and liberties we cherish. But beyond the traditional celebrations, I find myself ruminating on a different kind of freedom, one that's increasingly vital in our digital age: freedom in our Operational Technology (OT) environments.

For too long, our critical infrastructure has been held captive by outdated security paradigms. I've been thinking about the freedoms we fight for in the OT space, and how BlastWave is helping to secure that independence.

Freedom from Passwords

Think about the sheer burden of passwords. They're a necessary evil in IT, but in OT, where systems are often legacy, air-gapped (or thought to be), contain default passwords or no authentication at all, and are managed by operators who aren't cybersecurity experts, they become a huge vulnerability. Passwords can be stolen, guessed, or simply forgotten, creating entry points for attackers to exploit.

At BlastWave, we believe in freedom from passwords. Our approach eliminates the need for them entirely, replacing them with a robust, cryptographically enforced identity and access management system. Imagine an OT environment where access is granted based on trusted identities and policies, not easily compromised strings of characters. This shift removes a significant portion of the attack surface, liberating operators from the constant worry of password hygiene.

Freedom from Hacking Scans

One of the first steps for any attacker is reconnaissance – scanning your network to map out devices, identify open ports, and find vulnerabilities. In traditional networks, this is often like walking into a brightly lit room; everything is visible, making it easy for adversaries to plan their moves.

Our core innovation, network cloaking, delivers freedom from hacking scans. We create a secure overlay network that makes your underlying OT infrastructure virtually invisible to unauthorized entities. If an attacker tries to scan your network, they'll find... nothing. No responses, no pings, no open ports to exploit. It's like turning off the lights and becoming undetectable. This "virtual air gap" means that even if an attacker somehow breaches your perimeter, they can't see what's inside, effectively making reconnaissance hopeless.

Freedom from Malware Spreading

Perhaps one of the most terrifying scenarios in OT is malware spreading laterally. A single infected workstation or compromised device can quickly propagate malicious code across an entire industrial network, leading to widespread disruption, safety hazards, and catastrophic downtime. The traditional "flat" network architecture often allows malware to move unchecked once it's inside.

BlastWave provides freedom from malware spreading through granular microsegmentation and strict policy enforcement. In our secure overlay, every device, every connection, is explicitly authorized. If a piece of malware attempts to move from one compromised point to another unauthorized system, it simply can't. The secure overlay acts like a series of individual, air-gapped compartments. It even prevents egress OUT of your environment if it isn’t explicitly authorized, meaning command and control backdoors have no way to “phone home”. (Recall the recent story about Solar power inverters having a built-in software kill switch that could be remotely activated.) If an entity gets infected, the malware is contained, unable to spread and wreak havoc across your entire OT environment. This drastically limits the blast radius of any attack, giving you the control and resilience needed to maintain operations.

Securing Our Digital Independence

This Fourth of July, as we reflect on the hard-won freedoms of the past, let's also look to the future of digital freedom. Our industrial control systems, our critical infrastructure, and the very fabric of our modern society depend on robust, proactive security. The old ways of defending a perimeter are no longer enough.

At BlastWave, we are committed to delivering true digital independence for OT environments – freedom from the vulnerabilities of passwords, freedom from the constant threat of hacking scans, and freedom from the devastating impact of malware spreading. We believe that by making hacking hopeless, we can help secure a more resilient and free future for all.
