Stop Tailgating Before It Becomes a Security Incident

Cobalt Monitoring Intelligence detects unauthorized access at badge-controlled doors, enforces badge compliance through automated messaging, and gives your team measurable data to reduce tailgating over time.

Tailgating Is a Silent Threat

Most organizations know tailgating happens. Almost none can measure it, enforce against it, or prove it’s improving.

Undetected Unauthorized Access

Badge readers track who badged in — not who walked in behind them. Traditional access control systems have no way to flag when an unauthorized person follows a badged employee through a secured door, leaving gaps in your perimeter that grow with every shift change.

No Accountability, No Behavior Change

When employees allow tailgaters, there are no consequences and no feedback loop. Without enforcement, badge-holding culture erodes over time. Security teams are left writing policies that no one follows because no one knows when they’re being violated.

Zero Visibility Into Scope

Which doors are worst? What time of day? How many per week? Without data, you can’t prioritize resources, justify investment, or measure whether your interventions are working. Tailgating remains an anecdotal problem — impossible to manage.

AI-Powered Tailgating Prevention

From detection to enforcement to measurable behavior change — Cobalt Monitoring Intelligence turns tailgating from an invisible problem into a manageable one.

1. Real-Time Tailgating Detection

   Video analytics at badge-controlled doors detect when multiple people pass through on a single badge event. Each detection is logged with video evidence, timestamp, and door location — giving your team a verified record, not just an access log.

2. Automated Enforcement Messaging

   When a tailgating event is confirmed, Cobalt Monitoring Intelligence can automatically send a notification to the badge holder via text, email, or Slack. This creates an immediate accountability loop without requiring security staff to manually follow up.

3. Behavioral Change at Scale

   Enterprise deployment data shows that organizations sending automated messages to employees who allow tailgaters see an immediate decrease in tailgating incidents. The notification itself becomes the intervention — changing behavior without confrontation.

4. Trend Analysis & Door-Level Metrics

   Every tailgating event feeds into the dashboard, where security leaders can track tailgating rates by door, by day, and over time. Identify your highest-risk access points, measure the impact of enforcement policies, and report results to leadership.

The Tailgating Handler

Each tailgating event follows a dedicated Handler workflow — from initial detection through automated resolution.

Detect
Video analytics at a badge-controlled door identifies that more than one person passed through on a single badge event.

Reason
The Handler reviews the video clip, confirms the tailgating event, and identifies the badge holder associated with the access event.

Act
An automated notification is sent to the badge holder. If escalation criteria are met, the Handler routes to a security operator for review.

Resolve
The event is logged with video evidence, badge holder details, and outcome — feeding into trend dashboards for ongoing measurement.

Measuring What Was Previously Invisible

Every organization’s tailgating risks are different. Monitoring specific access points enables data-driven adjustments that manual processes can’t achieve.

What Your Security Team Gets Back

Tailgating prevention frees your team to focus on higher-value work — while giving leadership the data to prove your program is working.

From Reactive to Proactive

Instead of discovering tailgating after an incident, your team has continuous visibility into unauthorized access — enabling prevention rather than investigation.

Enforcement Without Confrontation

Automated messaging creates accountability without requiring guards at doorways. Badge compliance improves passively, and your team spends less time on manual follow-ups.

Data for Leadership Reporting

Quantified tailgating trends give security leaders the evidence they need to justify investments, adjust policies, and demonstrate measurable improvement to executive stakeholders.

How It Works

Common Tailgating & Unauthorized Entry Scenarios

Shift Change Surges

High-traffic entry points during shift changes are the most common source of tailgating. Cobalt Monitoring Intelligence monitors these peak windows, identifies repeat patterns, and flags doors with the highest tailgating rates — enabling targeted enforcement where it matters most.

After-Hours Unauthorized Access

A badge event at 2 AM followed by a second person entering is a fundamentally different risk than lunchtime tailgating. Handlers apply contextual rules — after-hours tailgating at a restricted area triggers immediate escalation to a security operator, not just an automated message.

Visitor & Delivery Tailgating

Contractors, visitors, and delivery personnel following employees through badge-controlled doors bypass your visitor management system entirely. Cobalt Monitoring Intelligence detects these events and can trigger specific workflows — visitor desk notification, contractor badge verification, or security dispatch.

Executive & Restricted Area Access

Certain doors require zero-tolerance enforcement — server rooms, executive floors, research labs. Handlers can apply elevated response protocols for these access points, including immediate security operator review and PACS lockdown if warranted.

Frequently Asked Questions

How does Cobalt Monitoring Intelligence detect tailgating?

Cobalt Monitoring Intelligence uses video analytics at badge-controlled doors to identify when more than one person passes through on a single badge event. Each detection is verified with video evidence and logged with the associated badge holder, timestamp, and door location.

Can automated messages really reduce tailgating?

Yes. Enterprise deployment data shows that organizations sending automated notifications to badge holders who allow tailgaters see an immediate decrease in tailgating incidents.

Can Handlers apply different rules to different doors?

Yes. Each access point can have its own escalation criteria. A lobby door during business hours might trigger an automated message, while a server room door after hours triggers immediate escalation to a security operator with PACS lockdown capabilities.
