Critical Incidents including cyber-attacks and the knock-on effect to your cyber and operational resilience
NCSC: "During a cyber incident, your usual communications channels may not be available.
You may need to establish alternative ways to keep in touch with staff, stakeholders and
customers, using phone lines, messaging apps or social media platforms"
"Consider options for secure or alternative communications in event of a sensitive incident,
or where normal channels are unavailable due to network/email/phone system outage"
