As part of our partnership with IT AWACS, we had the opportunity to take part in the IT Academy event in the Czech Republic. The meeting provided space for discussions on practical cybersecurity challenges and the role of effective communication in incident response. This naturally raises the question of which communication channels truly work in critical situations.
In incident response, success is not determined solely by advanced tools or detection systems. Very often, it is the simplicity and reliability of communication that decides whether a response happens on time.
This perspective was shared by Andrzej Kubala from the SMSEagle team, who focused on out‑of‑band (OOB) communication in cybersecurity. Rather than treating OOB communication as a phase that begins after an incident is detected, the presentation highlighted it as a deliberate, independent communication layer — designed to remain available even when primary systems or networks fail.
One of the examples discussed during the presentation was the well‑known Equifax security breach. It clearly showed that in many situations the problem is not the lack of alerts or detection systems. The real issue is an ineffective communication chain, where incident information does not reach the right people in time.

This is why communication independent of corporate networks, servers, and applications is critical. Andrzej described scenarios in which “in‑band” channels fail, while a simple and independent channel like SMS remains one of the most reliable ways to deliver alerts. Its independence makes it especially valuable in environments where other systems are disrupted, isolated, or deliberately shut down.

In industrial environments, Modbus TCP gets used to keep an eye on PLCs, sensors and automation systems. But the thing is, Modbus just doesn’t come with built-in notification tools that tell you when something has gone wrong. As a result, Modbus SMS alerts are usually handled by a separate layer that takes in register data & sends out SMS & voice alerts.
We are pleased to announce the introduction of a new hardware revision of our NXS-9700-5G device Revision 5 (Rev.5). This updated hardware platform will replace the previous Revision 4 (Rev.4) in regular production.
