How It Works
Security Vulnerability Assessment
​1. Private Intake Call
​
A short, confidential conversation to understand your concerns, timeline, and environment.
​
2. On‑Site Sweep & Assessment
​
We deploy in person to conduct a methodical counter‑surveillance sweep using professional methodology and operational discipline.
​
3. Findings & Recommendations
​
You receive a clear, actionable briefing. If issues are found, we outline next steps immediately.
​
No unnecessary reports. No jargon. Just clarity.
