Here is a list of the top 10 data leaks that have cost even Fortune 500 companies dearly – and how such tragedies can be averted.
Due to the COVID-19 Pandemic crisis, more and more organizations are shifting to the remote mode of operations. While this has ensured continuity of work, it has also given rise to cybersecurity risks and data breaches.
According to a security report, as much as 8.4 billion records have been compromised in the first quarter itself. This is a 213% increase when compared to the data breaches last year first quarter.
