Project Sonar started in September of 2013 with the goal of improving security through the active analysis of public networks. While the first few months focused almost entirely on SSL, DNS, and HTTP enumeration, the discoveries and insights derived from these datasets, especially around the identification of systems unknown to IT teams, led to the expansion of Project Sonar to include the scanning of UDP services.
Today, Project Sonar conducts internet-wide surveys across more than 70 different services and protocols to gain insights into global exposure to common vulnerabilities. In turn, this informs Rapid7’s more focused studies such as the Quarterly Threat Reports and the National Exposure Index, as well as our product development and related research. The datasets are available to the public at opendata.rapid7.com in an effort to enable further security research.
For endpoint studies, Project Sonar gathers data in two stages: In the first stage, all public IPv4 addresses (about 3.6 billion of them, excluding those opted-out) are scanned in an attempt to determine which have the respective service port open. Endpoints identified as having this port and protocol open are then communicated with, with the hope of extracting useful intelligence. As part of these activities, Sonar discovers names that might represent DNS records. For example, Sonar will obtain names from HTML links discovered during HTTP studies, and will extract the Common Name and other names included as part of SSL certificates. Sonar then performs weekly DNS studies using nearly 3 billion names as input, asking for several different DNS record types with useful intelligence.
Using this data, Project Sonar helps security practitioners and researchers:
While Project Sonar exists to ultimately improve our collective security posture, you may opt to whitelist or blacklist the subnets from which it scans by emailing email@example.com with your CIDR blocks/list of IP addresses and affiliation.

Our team makes Project Sonar datasets available to the public, so that you can get started on your own security research.
The National Exposure Index aims to better understand the nature of internet exposure around the world. See where your country stacks up in 2018.

In this video, Bob Rudis, Chief Data Scientist at Rapid7, digs deeper into how Project Sonar data is being put to use by the Labs team, including a recent (and pretty impressive) impact story.
In this week’s Whiteboard Wednesday, Bob Rudis, chief data scientist at Rapid7, revisits the presentation he gave at Rapid7’s 2017 UNITED conference. He digs deeper into how the data from Project Sonar and Heisenberg Cloud are being put to use by the Rapid7 Labs team, as well as the upcoming launch of a new study on headless browser HTTP scans.
