Insider Threats in 2025: Detecting Risks Within

Introduction

Most companies focus on outside attackers, but some of the biggest risks come from within. In 2025, insider threats — whether malicious or accidental — are among the top causes of data breaches.

Types of Insider Threats
  • Malicious insiders – disgruntled employees stealing data.
  • Negligent insiders – careless mistakes like misconfigured files.
  • Compromised insiders – accounts hijacked by attackers.
Why Insider Threats Are Growing
  • Remote work makes employee oversight harder.
  • Increased use of cloud apps widens access points.
  • Sophisticated phishing compromises employee credentials.
How to Detect and Prevent Insider Threats
  1. User behavior analytics (UBA) to flag unusual activity.
  2. Least privilege access – only give employees what they need.
  3. Regular audits of file sharing and permissions.
  4. Culture of security – train employees to act responsibly.
Conclusion

The call is coming from inside the house. Proactive insider threat management protects not just your data, but your reputation and client trust.
