Strengthening insider risk detection in a leading Nordic bank

The Customer

A leading Northern European bank serving millions of customers across the Nordic region operates in one of the world's most highly regulated and trust-dependent industries. With thousands of employees, access to sensitive financial data, and responsibility for critical digital infrastructure, the bank must meet stringent regulatory compliance requirements while defending against an increasingly complex cyber threat landscape. As insider risks continue to grow in sophistication, safeguarding customer data, maintaining operational integrity, and preserving customer trust remain top priorities.

The Challenge

Like many financial institutions, the bank operates in an environment where cyber threats, regulatory compliance and reputational risk are constant concerns. While traditional security tools are effectively detecting many external threats, identifying and mitigating insider risk remains a far greater challenge. One particularly serious indicator of insider risk is employees accessing child sexual abuse material (CSAM) on corporate devices. Beyond illegal, such activity can expose the bank to significant reputational damage, regulatory penalties, and legal consequences. It also signals elevated security risks, as individuals engaging in this behavior can become vulnerable to blackmail, coercion, or other forms of exploitation.

The bank's security team needed a way to:

• Detect high-risk, compromising employee behaviors before they become an insider risk.
• Reduce the risk for employees to become vulnerable to coercion, blackmail, or exploitation.
• Strengthen governance and demonstrate proactive risk management.
• Protect the bank's reputation and maintain the trust of customers, regulators, and shareholders.

The Solution

The bank implemented NetClean ProActive as part of its insider risk and security operations strategy.

By continuously monitoring corporate devices for verified indicators of high-risk behavior, NetClean ProActive provides high-confidence intelligence that helps identify potential insider threats and compromised users at an early stage.

Unlike traditional monitoring tools, NetClean delivers verified detections with no extra noise, allowing investigators to focus efforts on genuine risk signals. The solution integrates seamlessly into existing SOC and SIEM environments, enabling analysts to correlate NetClean intelligence with other security indicators.
