# Incident Report: Guidance on Cybersecurity Disclosure and Response
## Executive Summary
This article outlines the critical importance of proper disclosure and adherence to regulatory requirements following a cyber incident, particularly within the UK jurisdiction, emphasizing the roles of legal counsel and cyber insurance. The primary focus is on the necessary immediate steps related to mandatory regulatory reporting (like to the ICO, FCA, or DoT) which must occur while investigation and recovery are ongoing. The key takeaway is that timely and accurate disclosure, often facilitated by specialized legal advice secured via cyber insurance, can mitigate financial penalties and reputational damage.

- **What could have been done better:** Lack of preparation for mandatory disclosure timelines or failure to engage specialized counsel.
## Recommendations
- Seek specialized legal advice immediately upon identifying a potentially material incident.
- Inform cyber insurers promptly to leverage provided services (legal, regulatory filing).
- Conduct regular cyber incident tabletop exercises to refine regulatory disclosure processes.
- Report to law enforcement, even if not mandatory, as they may possess intelligence aiding recovery (e.g., knowledge of decryptors).
- Understand and plan for sector-specific and general mandatory disclosure obligations across all relevant geographies.
