Exclusive: DataWalk Explained by Chris Westphal

July 9, 2019

An Interview with Chris Westphal” provides an in-depth review of a company now disrupting the analytic and investigative software landscape.

DataWalk is a company shaped by a patented method for making sense of different types of data. The technique is novel and makes it possible for analysts to extract high value insights from large flows of data in near real time with an unprecedented ease of use.

DarkCyber interviewed in late June 2019 Chris Westphal, the innovator who co-founded Visual Analytics. That company’s combination of analytics methods and visualizations was acquired by Raytheon in 2013. Now Westphal is applying his talents to a new venture DataWalk.

Westphal, who monitors advanced analytics, learned about DataWalk and joined the firm in 2017 as the Chief Analytics Officer. The company has grown rapidly and now has client relationships with corporations, governments, and ministries throughout the world. Applications of the DataWalk technology include investigators focused on fraud, corruption, and serious crimes.

Unlike most investigative and analytics systems, users can obtain actionable outputs by pointing and clicking. The system captures these clicks on a ribbon. The actions on the ribbon can be modified, replayed, and shared.

In an exclusive interview with Mr. Westphal, DarkCyber learned:

The [DataWalk] system gets “smarter” by encoding the analytical workflows used to query the data; it stores the steps, values, and filters to produce results thereby delivering more consistency and reliability while minimizing the training time for new users. These workflows (aka “easy buttons”) represent domain or mission-specific knowledge acquired directly from the client’s operations and derived from their own data; a perfect trifecta!

One of the differentiating features of DataWalk’s platform is that it squarely addresses the shortage of trained analysts and investigators in many organizations. Westphal pointed out:

…The workflow idea is one of the ingredients in the DataWalk secret sauce. Not only do these workflows capture the domain expertise of the users and offer management insights and metrics into their operations such as utilization, performance, and throughput, they also form the basis for scoring any entity in the system. DataWalk allows users to create risk scores for any combination of workflows, each with a user-defined weight, to produce an overall, aggregated score for every entity. Want to find the most suspicious person? Easy, just select the person with the highest risk-score and review which workflows were activated. Simple. Adaptable. Efficient.

Another problem some investigative and analytic system developers face is user criticism. According to Westphal, DataWalk takes a different approach:

We listen carefully to our end-user community. We actively solicit their feedback and we prioritize their inputs. We try to solve problems versus selling licenses… DataWalk is focused on interfacing to a wide range of data providers and other technology companies. We want to create a seamless user experience that maximizes the utility of the system in the context of our client’s operational environments.
