Kroll is the largest global incident response provider with unrivalled expertise and frontline threat intel to protect, detect, and respond against cyberattacks.

No matter the type of data loss or cybercrime, Kroll has the experience and resources (human and technology) to move quickly, to discern, isolate and secure valuable relevant data and investigate the digital trail, wherever it may lead. For example, in the case of malicious insiders, we can combine computer forensic expertise with traditional investigative methodology, including interviews and surveillance, to retrace the behavior of people who may have had access to protected or proprietary information.

In the event of digital attacks, such as malware, ransomware or an email account compromise, Kroll’s cyber investigation teams can collect and examine physical and digital evidence to uncover important information, such as where, when and how an incident occurred—and if systems are still at risk. We will determine what data was compromised and whether digital evidence was erased or modified. We will also work with your teams to recover data, whenever possible, and recreate events and exchanges so that you have an accurate diagnosis to develop an effective recovery plan.


With the rising concerns of ransomware and intrusions that leverage data exfiltration, Kroll’s incident response teams have not only the experience to properly investigate the many aspects of risk to data, but also the technical understanding of how to properly contain the threat and eject active actors from compromised networks.

Case Study – Insider Threat Investigation

Insider Threat Investigation
Watch Michael Quinn, a managing director in our practice, recount an insider threat investigation his team conducted.

A global software company based in Europe received an email from an anonymous source stating the sender had access to personally identifiable information, confidential financial data and IP source code for one of its subsidiaries. The sender gave Kroll’s client two weeks to pay a ransom of one million euros in bitcoin before it was leaked. Kroll's forensic investigators ascertained that an insider threat was the source of the infiltration, identified the individual responsible and provided the necessary evidence to assist with a prosecution.
