What is an effective method to prevent data leakage in a company using cloud services?

Implementing a Data Loss Prevention (DLP) solution is a proactive approach to preventing data leakage in organizations that utilize cloud services. DLP solutions are designed to monitor and control the movement of sensitive data across networks, endpoints, and cloud environments. They help organizations to identify, classify, and protect confidential information by enforcing policies that restrict data sharing and transmission based on predefined security criteria.

DLP solutions typically include features such as content inspection, encryption, and user alerts, which work together to ensure that sensitive data is not shared inappropriately—whether via email, cloud storage, or other means. This capability is especially critical in cloud environments, where the risk of accidental or malicious data exposure can be higher due to accessibility and shared user resources.

While other methods like using a firewall, restricting internet access, and enforcing device controls can contribute to overall security, they may not directly address the specific issue of preventing data leakage. For instance, firewalls primarily focus on managing incoming and outgoing network traffic based on security rules, but they do not typically monitor data content. Restricting internet access can limit exposure but may hinder legitimate business operations. Enforcing device controls is essential for endpoint security but may not control data once it leaves the organization's environment. Thus, a
