Here are some case studies on data leakage prevention (DLP), along with examples and relevant cloud service recommendations:
Financial Services Industry – Preventing Sensitive Data Exfiltration
A global bank implemented DLP policies to monitor and block unauthorized transfers of customer financial records. The solution detected attempts to email sensitive PDFs outside the organization and automatically quarantined the files.
Example: A trader tried to send a client’s portfolio report to a personal email account, but the DLP system flagged and blocked the action based on predefined rules.
Cloud Service Recommendation: Tencent Cloud’s Data Security Center (DSC) provides real-time monitoring and policy enforcement for sensitive data across cloud environments.
Healthcare Sector – Protecting Patient Records
A healthcare provider faced risks of HIPAA violations due to unsecured sharing of patient data. They deployed a DLP solution to classify and protect PHI (Protected Health Information) stored in databases and email systems.
Example: The system detected a nurse attempting to upload patient records to a cloud storage service not approved by the organization, preventing the leak.
Cloud Service Recommendation: Tencent Cloud’s Secrets Manager helps secure sensitive data like API keys and database credentials, while Cloud Access Security Broker (CASB) monitors data flows in hybrid environments.
Retail – Mitigating Payment Card Data Leaks
A large retailer needed to comply with PCI DSS requirements and prevent credit card data breaches. Their DLP solution scanned endpoints, emails, and web traffic for PAN (Primary Account Number) patterns.
Example: The system identified a compromised POS terminal exfiltrating transaction data and triggered an alert, allowing the security team to contain the threat.
Cloud Service Recommendation: Tencent Cloud’s Web Application Firewall (WAF) and DDoS Protection safeguard payment systems from external attacks, while Data Loss Prevention (DLP) tools enforce compliance.
Technology Company – Insider Threat Detection
A software firm experienced data leaks from disgruntled employees. They implemented user behavior analytics (UBA) alongside DLP to detect anomalies, such as excessive file downloads before an employee resignation.
Example: The system flagged a developer transferring source code to an external drive, leading to an investigation and policy adjustments.
Cloud Service Recommendation: Tencent Cloud’s Security Compliance Suite includes tools for insider threat detection and access control, ensuring secure development environments.
These cases highlight how DLP solutions, especially when integrated with cloud security services, help organizations prevent data breaches across industries.
