Sqrrl is a graph database management system (DBMS) . It uses secure, adaptable NoSQL built from Apache Accumulo. Originally founded by former employees of the National Security Agency (NSA), Sqrrl focuses on cybersecurity.

The main product from Sqrrl is Sqrrl Enterprise, which is a solution for enterprise users on top of Accumulo that can handle massive structured and/or unstructured data sets. A Sqrrl whitepaper describes Sqrrl Enterprise as a threat hunting tool that uses large amounts of data with linked data analysis to aid users going through the 'hunting loop'. In particular, Sqrrl manages data and can display it to users raw or in the form of visualizations for analytics, finding threat patterns, or for further investigation.

Sqrrl has native Hadoop integration and supports multi-structured data.


Sqrrl development began in 2011. As a company, it was founded by Ely Kahn and Oren J. Falkowitz who worked in cybersecurity before creating Sqrrl. Sqrrl was built on Apache Accumulo. Customers using Sqrrl came from both the private and public sector.

In January of 2018, Sqrrl was acquired by Amazon Web Services (AWS). Existing users of Sqrrl were able to continue using the software without any changes. In late November 2018, Sqrrl co-founder Ely Kahn (who is now a Security Strategist at AWS) commented on the release of AWS Security Hub, which includes visualizations and security remediation recommendations. However, there were no statements made explicitly about Sqrrl's integration with AWS.

Query Interface

Custom API

Sqrrl Enterprise offers users a proprietary query language called SqrrlQL that is integrated with the cell-level security concept. Users are able to execute SQL-like queries (key-value), full-text queries, or graph searches.

Data Model

Key/Value Graph

After data is ingested, the Sqrrl Enterprise product details each piece at a cell level. Data can be a key/value pair or a field in a JSON document. Sqrrl then uses secondary indexing techniques to store the data in Apache Accumulo in its native form. This flat architecture allows Sqrrl to handle data of different structures.

In 2016, a presentation by Sqrrl stated that the version of Accumulo used by Sqrrl Enterprise stores sorted key-value pairs. The data model itself uses raw events and linked data. Sqrrl is also considered a graph DBMS because it represents data to users in a graphical format and is schema-free. Custom iterators for Accumulo developed by Sqrrl allow users to complete graph analysis on the data.
