Why London Businesses Need Incident Response

London is the United Kingdom's capital and one of the world's leading financial centres. the City of London and Canary Wharf, the London Stock Exchange, Tech City around Shoreditch concentrate the activity that attackers actually follow.

CBEST threat-intelligence-led testing applies to systemically important financial institutions, and Cyber Essentials certification is a precondition for many UK public sector contracts.

Organisations here answer to the Information Commissioner's Office (ICO) under the UK GDPR and Data Protection Act 2018, which requires breach notification within 72 hours to the ICO. incident response is scoped to produce the evidence that obligation demands.

Sector supervision adds a second layer: FCA for financial services, Bank of England for banking, NCSC for national cyber security. Findings are mapped to UK GDPR, Cyber Essentials / Cyber Essentials Plus, ISO 27001 so they are usable in an audit rather than only in a security review.
