Cyber incident grab bag: Informing and supporting

How to inform and support staff, partners, residents and business during a cyber incident.


This section provides guidance on how to make sure that you are informing and supporting staff and partners, residents, and businesses effectively during a cyber incident. It focuses on communicating safely, transparently and empathetically to maintain trust with the public. See the ‘Coordinating with central government and law enforcement agencies’ and ‘Working with elected Members’ sections for guidance on communicating with these stakeholders.

Deciding whether to disclose

It is best practice to be honest, transparent and empathetic with the public when an incident occurs. In an incident, provide clear information that stakeholders, customers, and the media need to know, while also being careful not to disclose information that may heighten the risk to your organisation or customers. Even if the cause, impact, and nature of the incident is not fully understood, ensure key stakeholders are informed internally and externally using consistent messaging.  

When developing internal and external statements on the incident, consider using the Krebs Framework:

  • communicate what is known
  • communicate what is not known yet
  • explain what the organisation is doing
  • tell the public what they should do to safely continue accessing services
  • explain when, how and where more information will be available.

Your key strategic actions

(Note: these are a strategic guide, not an exhaustive list of every action you should take.)

To ensure that your communications and engagement support your response and recovery, and are helping rebuild trust, you should: 

  • Ensure clear responsibilities for your communications: confirm team roles, including the senior Gold strategic lead, Silver tactical, and Bronze operational command, and ensure the senior leadership team actively sponsors the communication response. Involve your comms team as part of the core response and use their expertise to guide your decisions and actions. 
  • Choose a safe and reliable way to communicate: establish a central source of truth (such as your council’s website or a temporary website if needed) and consider additional channels such a setting up a hotline number, designated email inbox, and social media. 
  • Agree key messages for the public and for internal staff: ensure all audiences receive timely and consistent information through appropriate and accessible channels. Keep comms as clear and jargon-free as possible and be clear in communicating what is known and what is unknown.  
  • Communicate clearly without increasing risk: be truthful and transparent, but avoid speculation, false reassurance or sharing information that could increase risk or cause unnecessary alarm.  
  • Establish a sustainable communication rhythm: set regular update points for staff, residents and businesses who are impacted by the incident. Use this to build confidence and trust in your response.
  • Identify where you may need to coordinate with other organisations: coordinate and align communications with suppliers and other affected councils/organisations, particularly in the event of a supply chain incident. This includes central government and agencies (the ‘coordinating with central government and law enforcement’ section contains more information about this).
  • Check with your insurers before releasing public communications: this is important to ensure that the information will not compromise contractual agreements or invalidate any potential claim. This applies even if you do not have specific cyber insurance (as other cover may still apply).
