When Groupon was accused of trademark infringement involving website metadata and SEO practices, they turned to Natsar for expert analysis and testimony. After conducting an in-depth technical investigation and presenting clear, evidence-based findings, the court ruled in Groupon’s favor and awarded them $325,000 in legal fees.
When one of the largest university medical centers in the United States uncovered an insider threat accessing highly confidential research and personnel information, Natsar was engaged to conduct a comprehensive forensic investigation.
Our work included forensic analysis of multiple devices, examination of cloud-based security logs in collaboration with the organization’s information security team, and acquisition of evidence from diverse sources. By aggregating and correlating this data, we were able to build a complete picture of the insider’s activities.
The investigation confirmed the unauthorized access, established a precise timeline of events, and identified exactly what information had been compromised. Natsar’s expert report provided the foundation for subsequent action and ultimately led to an FBI criminal investigation.
For the first time in our history, computer forensic evidence from Mr. Moulin has been used in legal hearings and provided proof of employee misconduct. To date, 100 percent of our cases have resulted in successful resolutions for our company, potentially saving thousands of dollars in unemployment and other legal claims.
Chief Financial Officer, National Security Sector
Mr. Moulin was assigned to conduct computer forensics on city equipment. His investigation resulted in obtaining critical information that led to two employees voluntarily resigning their positions with the city. His efforts also brought to light problems that need to be addressed to assure that the integrity of the Information Services Department is not compromised in the future.
