The Telegraph has managed to access public Trello boards containing staff performance data of more than 900 Regus employees. Make sure your Trello boards, and any other collaboration tools aren't publicly accessible.
Job performance details about more than 900 employees of a major office-space provider have been published online by accident after a staff review. Sales staff at Regus had been recorded showing researchers posing as clients around office space available to rent. Information about the employees was later published on Trello, a task-management website. And a spreadsheet with names, address and job performance data was found via Google by the Telegraph newspaper.
