A 45‑Day Pilot Plan for Browser DLP
Monitor → Warn → Block. Without slowing down the business.
The philosophy
Rushing to block mode creates friction and shadow workarounds. A phased approach builds trust with users while generating the data you need to tune policies.
"Start with visibility. End with enforcement. Skip the panic."
The 45‑Day Timeline
Days 1‑14: Monitor
Establish Baseline
- Deploy in audit‑only mode to a pilot group (50‑100 users)
- Log all events without blocking
- Identify high‑risk workflows and data types
- Generate first risk report for stakeholders
Days 15‑28: Warn
Educate Users
- Enable warning dialogs for high‑risk actions
- Add "justification" prompts for business‑critical exceptions
- Send weekly summary emails to pilot users
- Refine policies based on false positive feedback
Days 29‑42: Block
Enforce Policy
- Enable blocking for clearly critical patterns (SSNs, API keys)
- Maintain warn‑only for gray‑area scenarios
- Review and tune exception requests
- Prepare rollout plan for wider deployment
Days 43‑45: Review
Measure & Report
- Compile audit‑ready evidence package
- Calculate ROI: incidents prevented vs. productivity impact
- Present to leadership with recommendation
- Plan company‑wide rollout or expand pilot
Success metrics
Track these KPIs throughout the pilot:
- Event volume: How many risky actions per day/week?
- Data types: Which categories trigger most alerts?
- User feedback: Are warnings clear and actionable?
- False positives: Is legitimate work being blocked?
- Policy coverage: Are high‑risk scenarios caught?
Common pitfalls to avoid
- Starting in block mode (users panic, find workarounds)
- Pilot group too small (insufficient data)
- Ignoring feedback (policies become draconian)
- No executive sponsor (pilot dies in committee)
