Tableau adds encryption and governance to its platform

By: Maryse Gros

No program changes on Tableau’s conference after the announcement of its acquisition by Salesforce. The addition of technologies and functionalities will continue in order to build, around the data visualization software, a complete platform for data preparation and governance to be deployed securely in enterprise projects. Nevertheless, the Seattle-based editor reassures its customers: it keeps its name and its independence.

Live from Berlin. The acquisition of Tableau for $15.7bn by Salesforce, announced just 8 days ago, does not disrupt the European conference of the data visualization tools editor currently being held in Berlin (June, 17th-19th). Out of more than 2,000 participants, the French delegation brings together about 200 people. In France, the editor counts among its big clients groups like La Poste, Schneider Electric, BNP Paribas, Auchan, EDF, Criteo, Blablacar or OVH.

Tableau’s offer has been greatly strengthened in recent months with the arrival of an in-memory column database engine (Hyper), data preparation tools (Prep and Conductor) and natural language query functions (Ask Data). The ambition to develop a complete platform - which will remain independent - continues with the McKinley project aimed to improve the reliability and scalability of deployments, with server monitoring tools across different environments and, on the security side, rest and retrieval data encryption

planned for the 2019.3 version. Tableau has also tackled self-service governance with the development of Catalog, which will provide data lineage functions by the end of the year. Concerning querying data, after Ask Data, the Explain Data engine will help users understand trends occurring in the data.

“We will continue to make Tableau more intuitive for users working with data, with self-service and deployments in all formats,” said Adam Selipsky, President and CEO of Tableau. (Credit: LMI/MG)

In Berlin, the acquisition by Salesforce was not tackled right away during the plenary session. After an introduction on the importance of developing a culture of data in the company, Adam Selipsky, president and CEO of Tableau, wanted however to reassure customers, especially those who have engaged in critical projects based on the technology of the Seattle-based editor and who could now be concerned about having to question them. If the acquisition by Salesforce certainly opens a “new chapter” to accelerate the evolution of the platform, “Tableau will keep his name and continue to operate independently,” he said yesterday morning in Berlin. “I remain CEO and in many ways, everything continues as before, but the best of both worlds offers many opportunities.” It is still too early to say more. “There are a lot of things we do not know,” the CEO acknowledged, but wanted the audience to consider how much the artificial intelligence and machine learning capabilities developed by Salesforce within Einstein could offer Tableau. Visualization software is already popular among Salesforce users. The two editors’ engineering teams will work to create natively integrated experiences between their platforms. As for the sales teams, they have enormous opportunities to collaborate in the field, welcomes Adam Selipsky.

75 connectors to multiple data sources

The two US editors have many users in common, but there are also many customers they do not share yet, told us, during an interview, Edouard Beaucourt, Director France and Southern Europe of Tableau. “We are technology partners and in many cases Tableau is embedded within Salesforce applications.” The data visualization specialist already offers 75 connectors to import data from various sources and “one of our unique values is to be agnostic,” emphasizes Edouard Beaucourt.

In France, major public service institutions and banks were among the first customers of Tableau, soon joined by many start-ups and recently created companies such as Kapten or Happn. Over the past 18 months, a real take-off has also occurred in middle market companies, said Edouard Beaucourt, Director France and Southern Europe of Tableau. (Credit: LMI/MG)

In France, the editor’s largest customer remains BNP Paribas, closely followed by Schneider Electric with thousands of users. “More recently, Auchan has placed its strategic trust in us in a complicated context,” quotes the French director, explaining that the agnostic side of Tableau motivated the choice of the retailer who deployed the solution on two projects: “on the one hand with Google’s Big Query, on the other hand with Oracle’s Essbase, with the same ease for both to benefit from the data.” Auchan counts now 7,000 users of the analysis software among its executives (middle and top management) in 600 stores in France.

In order to integrate its offer, the French subsidiary of Tableau has teamed up with around twenty partners including Deloitte, Keyrus, B&D/OBS, Mydral, ActInVision and The Information Lab. When asked about how the software is used, Edouard Beaucourt pointed out that the product is available on-premise, under Windows, Linux or MacOS, that it is deployed in the three main public clouds (AWS, Azure, GCP) or that it can be consumed in SaaS mode on the Tableau Cloud (installed on AWS).

Blueprint, a guide and practices for a successful project

In Berlin, in addition to the many functional additions expected in version 2019.3, Tableau also emphasizes its actions that can help companies to develop a data culture. In this field, the editor has compiled Blueprint, a guide to help its customers through the successive stages of defining a strategy, setting up a project, deploying it, monitoring and maintaining it, in a context designed to extend its scope. Blueprint also covers training and good practices, as well as the project promotion dimension, user engagement and support, which are essential to create a framework conducive to community building. The editor has 86,000 corporate customers worldwide, including more than 15,000 in Europe.
