A Quick Primer on Insider Threats to Organizations

When we talk about threats to organizations, we often picture cybercriminals, violent actors, and organized groups.  But increasingly, some of the most damaging threats originate from within.  Whether intentional or accidental, insider threats are a growing risk that organizations cannot afford to ignore.

This blog kicks off a new blog series from Convoy Group, where we break down the insider threat problem, share real-world case studies, and offer practical, intelligence-led strategies for reducing risk.  Whether you are in corporate security, Human Resources (HR), Information Technology (IT), or leadership, this series is for you.

The Insider Threat Problem

Insider threats are not always high-profile cases like Edward Snowden or Chelsea Manning.  More often than not, insider threats originate from everyday employees who make small mistakes – or carry big grievances.

An insider threat is any risk posed by a person with legitimate access to your organization’s assets – whether physical, digital, or informational.  This includes employees, contractors, vendors, and partners.  The threat might be intentional or accidental, but the impact can be just as damaging.

Data About Insider Threats is Clear: It’s a Real Issue

According to the Department of Homeland Security, insider threats remain one of the most persistent and underestimated security risks in both the public and private sectors.  Many incidents go undetected for months, and some are never uncovered at all.

A great resource to explore this further is the Cybersecurity & Infrastructure Security Agency’s Insider Threat Mitigation Guide, which outlines common behaviors, indicators, and response strategies organizations can implement.

But the cost of insider threat’s to organizations is not just financial.  Insider threats can erode trust, damage reputation, and in some cases – especially in critical infrastructure, healthcare, or education – they can put lives at risk.

Why Insider Threats Are Growing

Several factors contribute to the rising threat:

• Remote and hybrid work have expanded attack surfaces.
• Third-party vendors blur the line between internal and external.
• Cultural tensions or unresolved workplace grievances can lead to retaliation.
• Sophisticated social engineering tactics can make people easier to target than systems.
• Compromising information can be publicly available and relatively easy to find.

These evolving conditions make it harder than ever to maintain visibility and control – especially when access is not always limited to full-time employees.

Insider Risk is Everyone’s Problem

Security teams cannot mitigate this risk alone.  HR, IT, legal, and leadership all have a role in building a culture where insider risks are taken seriously and addressed early.

That means that organizations need to approach this problem from multiple angles –training, clear policies, cross-department collaboration, and perhaps most importantly, they must prioritize making decisions based on good intelligence, not just instinct.

At Convoy Group, we help organizations approach this risk to organizations holistically.  Insider threats are often a symptom of deeper structural or cultural issues – and we believe you can’t solve what you can’t see.

What’s Next in the Series?

In the next blog, we’ll break down the three core types of insider threats – malicious, negligent, and unintentional – and share what to watch for before a mistake turns into a headline.
