Client: National Logistics Company
Industry: Transportation/Supply Chain
Solution: Consistent Accountable Entry

The Challenge: A Shortcut Becomes a Serious Security Risk

A Director of Security at a national logistics company—spanning 48 states—grew concerned about piggybacking (also known as tailgating). Employees would badge through turnstiles, then pass the badge back through so someone else, sometimes a colleague, or other times an uncleared visitor could slip in behind them.

While this may look harmless, it creates major security, liability, and safety concerns, especially during emergencies. Without an accurate record of who is inside the facility, mustering becomes chaotic, and evacuation protocols risk failure.

The Solution: Two Changes. One Big Leap in Security.

Data Link worked directly with the client to enhance their access control system:

• Anti-passback features track entry so each badge can only enter once without a proper exit. If someone scans again without exiting correctly, access is immediately blocked.
• Anti-tailgating detection triggers an alert if the turnstile or door stays open too long, signaling potential unauthorized entry.

These features not only block repeated badge use but also send real-time alerts to security staff, enabling rapid intervention.

The Outcome: Fewer Breaches. Faster Response. Full Accountability.

• Immediate reduction in piggybacking incidents—unauthorized entry attempts dropped dramatically overnight.
• Proactive response: Security personnel now get instant alerts, allowing them to intercept attempts in real time.
• Accurate accountability: The system now keeps a live roster of who’s inside at any moment—essential for mustering and emergency evacuation.

Why It Matters

• Stronger security posture — unauthorized entry is shut down before it becomes a threat.
• Reduced liability and improved compliance — every access point is tracked, creating a clear audit trail.
• Reliable emergency readiness — with a live roster of occupants, evacuation and mustering run smoothly.

Client Takeaway

By addressing piggybacking—not by installing new hardware, but by reinforcing controls already built into their system—the logistics company elevated security without disrupting operations.
