Unmasking Insider Threats: How Investigative Security Helps Organizations Address Risk From Within

Q&A with Mick Pinneke, Vice President of Investigations & Threat Management Practice at Allied Universal® Enhanced Protection Services

Insider threats rarely begin as an obvious crisis. More often, they surface as a control failure, unusual behavior, missing information, a questionable vendor relationship, or activity outside the normal operating picture. By the time leadership recognizes the risk, the exposure is often broader than initially assumed.

That dynamic is what makes insider threat detection a critical component of modern security programs. Risk is no longer limited to physical theft or employee fraud. It now includes data misuse, sabotage, vendor collusion, intellectual property loss, and other issues that can quietly impact operations, reputation, and legal exposure over time.

Mick Pinneke, Vice President of Investigations & Threat Management Practice at Allied Universal® Enhanced Protection Services, explains how insider risk management works in practice and where organizations often underestimate the challenge.

What is typically happening inside an organization when leaders raise concerns about insider threats?

In most cases, they are already reacting to something. They may have identified unusual activity, a possible fraud issue, a data concern, or another signal that suggests internal risk. The key question is not whether something occurred — it is whether what they are seeing represents the full picture.

That is where the investigative process begins. The goal is not just to confirm an issue, but to define its scope, determine how far it extends, and understand the potential business and legal impact. What starts as a single data point often turns out to be part of a larger pattern once relationships, timelines, and third parties are examined.

What makes insider threat detection challenging?

The challenge is not just the threat itself — it is visibility.

Traditional cases such as theft, embezzlement, and fraud still exist, but many insider risks now develop in environments where activity is less visible and harder to interpret. Cyber misuse, access abuse, or data exfiltration may not present as a clear event, but as subtle deviations over time.

That creates a gap. Organizations may have strong controls, but not always the ability to connect signals across systems, functions, or timelines.

Speed is another factor. Once one pathway is restricted, a determined insider may shift tactics. Effective programs depend on continuous evaluation and the ability to recognize when isolated signals begin to form a pattern.

What does an effective investigations response look like?

It starts with disciplined fact development.

Before interviews or conclusions, investigators focus on what is known, how it is known, and where the gaps are. From there, the work centers on reconstructing the full picture — not just validating the initial concern.

That includes examining how the issue surfaced, identifying who may be connected, and determining whether external parties are involved. In practice, that often means moving beyond a single incident to evaluate broader activity across transactions, systems, and relationships.

A strong investigative file is not just thorough — it is actionable. Whether the outcome involves employment action, civil litigation, or referral to law enforcement, the findings must stand on their own and support the next step.

What should an insider threat program include before an incident happens?

It begins with alignment around what matters most.

Organizations need to understand which assets carry the greatest risk, where exposure exists, and how those risks could realistically materialize. From there, insider threat management becomes a cross-functional effort.
Security, legal, IT, and human resources each see different parts of the risk picture. Without coordination, critical signals can remain isolated. A formal threat management structure helps ensure those perspectives are brought together and evaluated consistently.

Just as important is regular reassessment. As organizations evolve — through new systems, vendors, or business lines — the risk environment changes with them.

What are the most important steps security leaders should take now to reduce insider risk?

Focus on the areas where insider cases are most often missed or misunderstood.

1. Define what triggers escalation. Many organizations collect indicators but lack a shared threshold for action. Without clear ownership and timelines, signals can remain unaddressed until the issue has expanded.
2. Pay close attention to transition points. Role changes, terminations, contractor offboarding, and disciplinary actions are often where access, motive, and opportunity converge. These moments require tighter oversight than routine operations.
3. Train managers to recognize and document patterns. Insider cases rarely hinge on a single event. They develop over time, and early context is often lost if it is not captured consistently.
4. Use every substantiated case to identify control gaps. The most valuable outcome of an investigation is not resolution — it is understanding what allowed the issue to occur and ensuring those conditions no longer exist.

The objective is to shorten the time between the first signal and the first informed decision — and to ensure each incident strengthens the organization’s ability to detect and respond to risk moving forward.
