Step 1: Initial filtering
We hosted the source data in a single-tenancy environment where the client had both exclusive use of the hardware and software, as well as a dedicated physical space in a London data centre.
Step 2: General review
The client’s qualifying documents were then moved to a multi-tenanted system, where their data was kept separate from other projects by standard eDiscovery processes.
Dealing with highly confidential data
The client regarded the source data as both highly confidential and highly commercially sensitive – in addition, this data was originally located outside of the EU.
The initial filtering of the data (first-pass review and redactions) needed to be completed on an isolated system with dedicated review software.
The client did not wish the data to sit alongside other client data in a multi-tenanted environment, so we waited for the data gleaned from this initial filtering to be cleared for confidentiality (or if appropriate, redacted) before transferring it to a standard multi-tenanted system.
This methodology allowed for both a high level of security during the filtering stage and flexibility once the data was transferred.
