Storage Visibility and Risk Prioritization Made Easy
Understand what’s happening across your storage environment. Monitor activity, identify exposed resources, and focus on the risks that actually matter.
Fast deployment, immediate visibility
Get up and running in minutes with a guided CloudFormation setup. Connect your environment and start seeing activity without managing infrastructure or slowing teams down.
See who’s accessing your data
Know exactly who did what, when, and where. Track reads, writes, deletes, and configuration changes across your storage. Whether it’s normal usage, unusual access patterns, or something more serious, you can see it clearly and investigate without guesswork.
Detect real threats, not just anomalies
From unusual access patterns to coordinated activity across accounts, DataDefender surfaces behavior that actually matters. You’re not just seeing anomalies, you’re understanding what’s happening and why.
Scanning Overview
Find what’s exposed and control it
Public storage is where things break. DataDefender surfaces all publicly accessible resources in one place, shows what data they contain, and lets you quickly review, approve, or flag them as violations at scale.
Know what actually matters
Not all data carries the same risk. Identify sensitive data across your storage and understand where it lives so you can focus on the issues that actually impact your business.
Cut through the noise
You don’t need more alerts. You need the right ones. DataDefender surfaces the issues that matter most so your team can focus on what needs attention now instead of sorting through thousands of low-value signals.
Investigate without slowing down
When something happens, you can answer the important questions fast. Search across activity, users, and resources to understand what happened and how it unfolded.
- Who accessed this data
- What actions were taken
- What changed over time
Get structured, exportable results to support investigations and reporting.

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.
