How we built Tablo’s best-in-class data architecture

Outset Medical leads the digital health revolution in nephrology, which is made possible by our diverse team and unique technology.

While we are a medical device company, many of our team members come from non-medical, consumer-focused backgrounds like Walmart eCommerce, Google, Apple, GoPro, and Nvidia. This was by design. We wanted to build a technology-driven innovation engine that reduces cost and dramatically elevates the patient care experience.

From the outset, we had a strong focus on data. We selected best in class technologies to support future growth and spent a lot of time designing a dynamically scalable, performant, and highly available architecture. That has been our mission – to build a data-driven organization that empowers customers and helps them achieve operational excellence.

The sentiment of one of my favorite quotes is the foundation of our vision.

“In God we trust, all others must bring data.” – W. Edwards Deming

What’s different about Tablo’s data ecosystem?

Tablo has lots of smart components and sensors that constantly transmit data.  Tablo’s software collects data from different sensors while orchestrating treatment.  The system also sends more than half a million data points per treatment in real time to Tablo Cloud, which analyzes the data with streaming analytics in real-time to provide insights to our customers and field engineers. 

Tablo is the only dialysis machine that can transmit detailed machine and treatment data in real time.

The Tablo ecosystem is designed with state of the art technologies for unlimited scale and speed.  The platform uses Kafka messaging platform (developed by large streamer Netflix) and a real-time data pipeline to easily manage and route large volumes of data.  Cloud infrastructure is hosted on Amazon Web Services (AWS) for secure, scalable, and highly available architecture.  All applications use restAPI to interface with different computing resources for better performance.

Secure Cloud Data Flows - Tablo Cloud Architecture

We keep data secure with industry-leading encryptions 

Security is paramount for any industry, but more important in the healthcare industry due to sensitive patient data.  

Outset has developed HIPAA-compliant architecture, which ensures the security of the data during storage and transmission using the best security algorithm possible. We use AES-256 bit encryption, also used by the Department of Defense, Google, and other trusted organizations. Breaking a symmetric 256-bit key by brute force requires fifty supercomputers that could check a billion billion (1018) AES keys per second (if such a device could ever be made) and would, in theory, require about 3×1051 years to exhaust the 256-bit keyspace.

Just to be sure, we hired a third-party qualified hacker from Rapid7, a multi-billion dollar market cap firm, to break into our system. After a week of trying different ways, they could not break into the Tablo device or Tablo Cloud to capture any data (much less sensitive data).  

What this means for providers and patients

We’re continuing to build a powerful, industry-leading data foundation with robust security architecture. Over the next few weeks, I’ll continue to shed some light on how our customers are using Tablo’s data to improve their dialysis programs.
