What Is a Data Diode? Learn About One of Our Core Technologies
If you've ever wondered about the science behind data diodes – such as how the technology outperforms firewalls and traditional intrusion detection/protection systems to safeguard critical networks – you're in for a real treat. In this post, we're going to explore how...
IEC 63452
Operational Technology (OT) networks are under increasing pressure to share data with enterprise systems, cloud analytics platforms, and security monitoring tools. At the same time, industrial operators must ensure that these connections do not introduce cyber risk...
Tactical Data Links
Tactical Data Links are a foundational element of modern military operations. They provide the mechanism by which platforms’ sensor tracks are exchanged and operators view time-critical information such as identification data, mission status, and command intent. By...
IT and OT Convergence: Bridging the Gap with IoT
Today’s businesses operating in industrial environments straddle two worlds: one is operational technology (OT), and the other, quickly expanding, is informational technology (IT). Up until recently, these areas were kept completely separate, sharing little...
Achieving OT to cloud convergence through cybersecurity
Did you miss our recent webinar where we explored OT to cloud convergence? Perhaps you'd like to watch the recording (available here) but you don't have time? No need to worry, I have you covered! The following is a written summary of our webinar and steps on how can...
Turning NATO’s digital backbone vision into reality, one trusted data flow at a time
When I moved from consulting and delivery into the secure data space, I didn’t expect my experience with complex, interdependent systems to be quite so relevant. But as NATO sets its sights on becoming a truly data-centric alliance, it’s clear that hands-on delivery...
Full Stream Ahead: Why Cross Domain Needs a Rethink
Since joining the 4Secure team, I’ve had the chance to dive deep into a subject that’s quickly gone from “that sounds interesting” to “why aren’t more people doing this already?”… streaming data securely between classified and sensitive domains. If you’ve worked in or...
Empowering Autonomous Defence through Secure Multi-Domain Interoperability
Autonomous systems such as drones, ground vehicles, naval assets, and satellites increasingly rely on secure, real-time data exchange to perform effectively. Seamless communication across classified and unclassified environments is critical to these systems’ ability...
AUKUS Pillar 2: Momentum without structure is a risk we can’t afford
When the AUKUS trilateral security partnership was announced in 2021, it understandably made global headlines. Much of the early focus centred on Pillar 1 – a landmark agreement to deliver conventionally armed, nuclear-powered submarines to Australia. But behind the...
