In part one and part two of this series, we've introduced the concept of where to draw the line between on-premise technology and cloud-based technology when building a modern and efficient e-discovery architecture that takes advantage of today's technology. In this final part, I want to discuss why a hybrid approach of on-premises software and a private hosted platform is the best solution for e-discovery-review.

Two key factors in making the decision about whether to put e-discovery technology behind the firewall or in a hosted solution such as cloud are cost-effectiveness and the ability to create an efficient and defensible process.

The nature of e-discovery review—the last major phase of e-discovery—is that of sharing and collaboration with outside counsel and others. Doing this in a completely secure and efficient manner is critical, which makes this phase a candidate for leveraging both on-premises software and a private hosted cloud review service.
