External communication is an essential part of incident response. It involves communicating with customers, partners, regulators, media, and law enforcement who are impacted or interested in the incident. To protect your reputation and comply with legal and ethical obligations, you should communicate in a timely, transparent, and consistent manner. To do so, it’s important to prepare a communication plan and a crisis communication team before an incident occurs. Identify the key messages, audiences, channels, and spokespersons for different scenarios and incidents. Additionally, you should communicate early and often with the affected parties and the public. Acknowledge the incident, apologize for any inconvenience caused, explain the impact and actions taken, and provide updates as the situation evolves. Moreover, be sure to communicate accurately and honestly with regulators and law enforcement. Report the incident as required by relevant laws and regulations, cooperate with investigations, and follow the recommendations or instructions given.
