Insider security breaches have become a costly and frequent reality for enterprises. Recent studies show that insider-led incidents are increasing in both frequency and financial impact – $400 million for the most recent Coinbase breach.

Let’s be real—insider threats are one of the biggest problems in cybersecurity today. You don’t always need an outside hacker to cause chaos. Sometimes, the threat is sitting right inside your own company. In fact, about 3 out of every 4 breaches last year involved people inside companies. And those breaches? They’re not cheap. The average one tied to insider activity cost companies almost $5 million.

In May, Coinbase disclosed a massive breach, one that exposed the personal data of over 69,000 users and could cost the company up to $400 million. The attackers didn’t break through firewalls or exploit zero days.
