Why DLP Matters
Data is your most valuable asset. DLP prevents sensitive information from leaving the organization through unauthorized channels—whether accidentally or maliciously.
The Data Risk
- 83% of data loss involves insider actions
- $165 per record breach cost
- 277 days average to identify a breach
Three Pillars of DLP
DLP Coverage Areas
Endpoint DLP
USB, print, clipboard
Network DLP
Email, web, transfers
Cloud DLP
SaaS, storage, APIs
Discovery
Find and classify data
Implementation Roadmap
DLP Deployment Phases
Phase 1: Discovery (M 1-2)
Data inventory, sensitive data discovery, risk prioritization
Phase 2: Policy (M 3-4)
Define data patterns, create rules, configure exceptions
Phase 3: Monitor (M 5-7)
Deploy in monitor mode, analyze hits, tune rules
Phase 4: Enforce (M 8+)
Enable enforcement, incident response, optimization
Monitor First
Always deploy in monitor mode first. Analyze policy hits, tune rules, and train users before enabling blocking to avoid business disruption.
