Quick response

A Relativity case can be set up in a matter of hours, and review can start while data is being added to the platform in the background. Together with our FTS colleagues from around the world, we can support a 24/7 review, if so desired, to tackle even the most high-pressure incidents.

Scalable and flexible

We are trained in tailoring Relativity to the needs of projects of all shapes and sizes. Projects we support range from a few hundred documents and one reviewer, to millions of documents involving 100+ reviewers from all over the world. We host projects for companies in and outside Switzerland, both online and stand-alone, with only part of the data shared with reviewers abroad – if data privacy laws so dictate.

Examples of our work

We have worked with many leading companies to deal with integrity issues and investigate allegations of fraud and corruption.

An industrial company had to investigate bribery allegations made against them

We were on site for the first crisis meeting within 1 hour of the initial call and addressed the biggest challenge: how to acquire data from high placed individuals in 12 countries with minimal business disruption.

Together with local FTS resources, we simultaneously imaged the personal devices and scanned the hardcopy documents of 35 custodians in Europe, the Middle East, Asia and Africa, returning each custodian’s devices within 4 hours. Additionally, we acquired over 20,000,000 emails, documents and financial records from both legacy and current (cloud-based) ERP systems.

While the collection was ongoing, data was transported to Zurich for processing and hosting on the Swiss review platform, where over 30 lawyers were reviewing files from within Germany, Ireland, the USA and Switzerland. 

FINMA ordered an AML review on 20,000 accounts within six months

We installed a server and more than 100 reviewer PCs in a stand-alone network on the client’s premises. The server ran a customised review platform, allowing for fine-grained review (based on language, access to client systems and experience) over multiple levels. We created a secure and user-friendly tool on the client’s network through which reviewers could ask the respective relationship managers questions about accounts.

A sports association suspected a dismissed executive of deleting files from the company’s IT equipment prior to handing it over to Human Resources

We performed a forensic analysis on the equipment and were able to confirm specialised wiping and file shredding software was used after the executive’s dismissal. We found evidence that an external hard disk, which was regularly connected to the executive’s laptop, had not been handed over. We found that the flash drives submitted had been connected to another device, only days before being handed over. Our client is using these findings in ongoing court proceedings.

A client received confidential financial information about their operations from an unknown email address

We were onsite a few hours after the initial call to set up a plan to find out how this data was leaked, and by whom. Data analytics specialists analysed the log files of the ERP system the data originated from; colleagues from Computer Forensics analysed the laptops of key custodians, and our eDiscovery team captured and analysed email and Internet traffic data to narrow down the list of suspects. A call-home email was sent back to the unknown email address to capture the perpetrator’s IP address. Our client is using our findings in ongoing legal proceedings, and to improve the security of their IT ecosystem.
