What is Proactive Data Loss Prevention? | Protect Sensitive Data From Leaving Your Organization
Ever wondered how sensitive data actually leaves an organization – and why traditional DLP tools only catch it after the damage is done?
This video breaks down Proactive Data Loss Prevention (DLP): what it is, how it works, and how it stops sensitive data before it ever leaves your network.
Every day, files move everywhere – emailed to the wrong person, uploaded to an unsecured portal, synced to a personal cloud drive, or copied to a USB stick.
Traditional DLP is reactive: it alerts you after the file has already moved. OPSWAT’s Proactive DLP scans content before the transfer happens, so sensitive data never gets the chance to leave in the first place.
In this video:
00:00:00 – Why sensitive data keeps leaking out of organizations
00:00:08 – Files move everywhere: the real risk surface
00:01:04 – 4 common ways sensitive data leaks happen
00:01:17 – Traditional (reactive) DLP vs. Proactive DLP
00:01:51 – Block, redact, or anonymize sensitive data automatically
00:02:15 – Detecting PII/PHI across file types (TXT, PDF, CSV, JPG, and more)
00:02:41 – AI-powered detection: OCR + content classification, multiple languages
00:03:44 – Mapping directly to PCI DSS, HIPAA, and GDPR
00:04:00 – Before vs. after: redaction in action
00:04:41 – Recap: what Proactive DLP changes for your organization
Frequently asked questions:
🔹What is Proactive DLP?
Proactive DLP Technology is OPSWAT’s approach to data loss prevention that inspects files for sensitive data – SSNs (Social Security Numbers), credit card numbers, PHI (Protected Health Information), API keys – before a transfer completes, rather than flagging it afterward.
🔹How is Proactive DLP different from traditional DLP?
Traditional DLP is reactive: it logs the event and alerts security teams after the file has already moved. Proactive DLP Technology inspects content before the transfer completes and can block, redact, or anonymize it on the spot.
🔹Can DLP detect sensitive data inside images and scanned documents?
Yes. Proactive DLP™ Technology uses OCR (Optical Character Recognition) to read text inside images and scanned PDFs, combined with AI-driven content classification to detect PII and PHI across 125+ supported file types.
🔹Does Proactive DLP help with compliance?
Yes. Proactive DLP detects and blocks regulated data types, including PII, PHI, and financial information, with customizable policies that help align with PCI-DSS, HIPAA, and GDPR requirements.
