The 2021 Report: Breach Exposure of the FTSE 100 highlights the significant security risk posed by password reuse among employees, who frequently use corporate credentials as personal logins on third-party sites. This behavior can provide easy entry points for cybercriminals to gain access to corporate systems and networks. In addition to corporate credentials, data breaches also expose personal information that can be used to bypass security measures and compromise enterprise networks. The report provides an infographic of the FTSE 100's breach exposure, and maintains the world's largest repository of recovered stolen credentials and personally identifiable information (PII).
