By addressing the unique challenges of cloud data protection, such as data residency and compliance requirements, Cloud DLP helps your organization maintain the confidentiality and integrity of sensitive data in the cloud.


Main causes of data leakage

Data leakage can occur due to several causes, including insider threats, employee negligence, and policy violations.

Insider threats are a major concern, as employees with malicious intent may intentionally leak sensitive data for personal gain or to harm the organization. This could include sharing confidential information with competitors or selling data on the dark web.

Employee negligence, on the other hand, involves accidental data leaks due to carelessness or lack of proper training. This can happen through misaddressed emails, lost devices, or sharing login credentials inadvertently.

Policy violations occur when employees knowingly or unknowingly disregard data security policies and procedures, leading to unauthorized data access or sharing.



How DLP tools work

DLP tools operate by leveraging sophisticated detection technologies to oversee data activities, thwart unauthorized access, and perform data audits to verify adherence to security policies.

These tools utilize a range of mechanisms, including keyword scanning, data fingerprinting, and regular expression matching to pinpoint sensitive data. They are capable of scrutinizing data in motion, at rest, and in use across endpoints, network traffic, and cloud services.

Additionally, DLP tools seamlessly connect with encryption technologies to safeguard data both at rest and in transit. By continuously monitoring and analyzing data patterns, anomalies, and user behavior, these tools are adept at proactively identifying and preventing data breaches.
