Since the launch of, several subscribers have reached out to our team to understand the next steps or what-to-do after a data breach has been discovered. In this post, we will be discussing some of the strategies to understand the risks and some of the actions which could mitigate the risks.

To truly understand the effect of a data breach, it’s critical to understand what information has got compromised and what hackers can do with it. Let’s a couple of scenarios –

    • Change your account passwords immediately, and if possible, turn on 2-factor authentication
    • Change passwords of all other accounts using the same or similar password. Almost every leading email service provider such as Gmail, Yahoo, Office 365 supports 2-factor authentication and we highly recommend to turn them on

    • Monitor your credit card transaction diligently for any anomalies
