Data Access and Exploration

Do you have trouble accessing data on the go?

Visualization tools and summary reports are great. But, as the saying goes, “the devil is in the …” Sometimes, you need the data for detailed analysis when you’re not connected and to share specifics when you’re back online.

Data Security

Your Data is Not Secure.

You protect your data repository. You protect your network.  Yet, thousands of data files are extracted and downloaded from your repository. These CSV and XLS files reside on your network drives, on employee machines, in the public cloud, and in employees email. These data files are the most vulnerable point of attack for malicious actors.

Data Efficiency

​Access Data Faster.

Transferring and uploading large data sets is slow.  What if you could access data orders of magnitude faster than now?  What if hours were compressed to seconds?

.BIG Integration for Enterprise Software

Your users routinely download data. They generate CSVs which sit unprotected, take up vast space, and are impractical for exploration (over 1mm rows).


Augmenting an Enterprise Solution with .BIG file generation vastly enhances a customer user’s ability to extract detailed data from the system. Users can download millions, 10s of millions, or 100s of millions of rows of data. The data is highly compressed (3-4x better than zipped CSVs), easily accessed, and fully secure.

.BIG files are much more than a replacement for CSV. .BIG integration extends your solution with secure data files that can be administered through your platform.
