Is your crisis communication physically separated?

When an incident hits, the NIS2 Directive requires organizations to stay operational. That includes coordinating actions and communication when standard infrastructure is no longer available.

And this is where many setups break.

A common risk is a Single Point of Failure - when a monitoring system tries to send alerts over the same network that has just failed. At the exact moment an alert matters most, it never reaches the people who need to act.

This is why physical separation and Out‑of‑Band (OOB) communication are essential.

In crisis scenarios - such as ransomware‑driven network paralysis, DDoS attacks, or BGP configuration errors - IP communication is disrupted first. Email, dashboards, and internal alerts disappear along with the network.

💡 Example:

A ransomware attack paralyzes the internal network, cutting the IT team off from standard alerts. The monitoring system detects critical anomalies but can’t send notifications through the compromised infrastructure. Because an OOB channel doesn’t share any points of failure with the internal network, the alert still reaches administrators via the GSM network - within the first minute of the incident.

That short time window allows teams to isolate systems immediately and limit the impact.

This is what operational continuity looks like in practice: not preventing incidents, but making sure critical information reaches the right people when standard channels fail.

SMSEagle supports this approach as a hardware gateway, delivering the most critical parameters - such as server‑room temperature, UPS status, or intrusion attempts - directly to a mobile phone, without relying on IP connectivity.

If your IT service provider relies only on cloud tools, an IP infrastructure failure on their end can cut you off from reacting.

How do you reduce this risk in practice?

Under NIS2, organizations have to implement measures proportional to the risk. In crisis communication, this usually means:

🔹 Shortening the chain of intermediaries in key processes.
🔹 Building alternative, independent communication channels.
🔹 Ensuring control over data and logs so you can show exactly what happened and when.

On‑premise solutions like SMSEagle gateways meet these requirements by limiting reliance on external communication services. They let you regain control over your critical alert channel.

💡 Example: During an incident, you decide to cut off part of your IT infrastructure from the outside network by air‑gapping it. Business systems, email, and messengers go down, but a local SMS gateway still works because it doesn't need the Internet to send alerts. This means your response procedure kicks off without delay and the tech team gets alerts instantly.

Reducing reliance on multi‑layered cloud services is a concrete step toward the operational resilience regulators require.

Because fewer intermediaries = higher security.

In regulated banking environments, reliability and control over message delivery are critical. Raiffeisen Bank uses SMSEagle to send operational SMS alerts from monitoring systems and deliver OTP messages with full local control.

No public cloud. No external SMS providers. Just predictable delivery, on-premise infrastructure, and compliance-ready communication.
