Insider Threats – The Risk Within Your Own Walls

When most people think about cyberattacks, they imagine hackers working from the outside. But some of the most dangerous threats come from inside the organization—whether intentional or accidental.

Insider threats fall into three categories:

• Malicious Insiders – Employees who steal data for profit or revenge.
• Negligent Insiders – Staff who unknowingly expose data through careless actions.
• Compromised Insiders – Accounts hijacked by external attackers.

The cost of insider threats is significant, with global damages estimated in the tens of billions annually. These risks are especially challenging because insiders often have legitimate access to systems.

Preventing insider threats requires:

• Strict access controls and least-privilege policies
• Continuous monitoring of user behavior
• Security awareness training for employees
• Automated alerts for unusual activity

At Denti Systems, we help organizations detect and prevent insider threats through behavioral analytics, access monitoring, and policy development.

The hardest threats to stop are often the ones closest to you—but with the right safeguards, they don’t have to be.
