I work as a project team leader in cybersecurity for a payments platform. My enthusiasm for the job has waned as a number of my warnings on critical security issues have gone unheeded. I am looking elsewhere for work, most likely in fintech, but I am aware that any eventual security breaches in my current job could tarnish my reputation. Given that I will have to sign a confidentiality agreement upon departure, what is the best course of action to take to protect my reputation in the long term?
