Why the Lack of Cloud Monitoring Causes Data Breaches
In the past 6 months, a number of high-profile data breaches, namely cryptocurrency exchange Coinbase, have resulted in the loss of millions of records and millions of dollars in fines, pipeline depletion, and restitution for the affected customers. In many ways, these data breaches are not the result of a lack of commitment to security by these companies, but are rather indicative of the evolving (and improving) tactics utilized by bad actors.

Preventing Internal and External Data Breaches with DataDefender
In the first half of 2025, Casmer Labs, Cloud Storage Security's internal threat laboratory, observed numerous high-profile data breaches and cybersecurity incidents that could be attributed to the lack of proactive activity monitoring. In the eyes of the press, the most popular example was the Coinbase attack, where overseas support staff exfiltrated sensitive data on behalf of cyber actors. On May 15, 2025, the day of its public disclosure, Coinbase (COIN) shares dropped 7% due to concerns about internal policies and an ongoing SEC investigation.
