One of the biggest complaints that’s heard across the industry is that of cost. “Too expensive” or “untenable pricing scale” are things we have been hearing from colleagues at conferences and on forums for years. Years! Yet we’re still stuck with this extremely frustrating pricing model that disincentivizes people from using the very tool they purchased. What do I mean? Let’s dive in.

DNS auditing is an integral part of any I.T. security program. Name resolutions can act as a great tip for discovering malware, command and control streams, or misbehaving employees. Acquiring DNS audit data can be difficult with some DNS servers (*cough* Windows *cough*); for this post we are going to show an extremely easy method of getting DNS audit data directly into Gravwell.

Gravwell Community Edition is perfect for monitoring your home network. With a generous 2GB/day ingest quota, you can capture netflow records, DNS requests, WiFi hotspot associations, and more. In this blog post, we’ll show how to ingest and analyze netflow records. We’ll assume you’ve already set up a Gravwell instance as described in the quickstart (https://dev.gravwell.io/docs/#!quickstart/community-edition.md); for this post, we’ll assume the Gravwell instance is at 192.168.1.52. Your instance will almost certainly be different, so be sure to substitute your own information.

Gravwell Community Edition

Back when we released the first version of Gravwell we immediately began sharing with friends and colleagues. Those initial testers primarily used Gravwell to monitor their home networks. They found rogue devices, neighbors leaching WiFi, poorly behaving IOT devices, and even some children that were playing video games when they should have been in bed. There was one problem, our friends wanted to give Gravwell to their friends but we aren't really a consumer software company. Our from-scratch secret sauce is what enables such game-changing pricing for larger enterprises but because we don't price on the data drip model it doesn't work for very small deployments. All that changes with the community edition...

Gravwell in the ICS Village and announcing Nozomi Integration

Jun 7, 2018 6:11:20 PM / by Corey Thuen posted in OT Analytics, Integrations

0 Comments

We're excited to join with Nozomi Networks in announcing our integration partnership which was piloted in the ICS Village at the RSA Sandbox in San Francisco earlier this year. Attendees at RSA were also able to see the first glimpse of the newly unveiled ICS Village. For those unfamiliar with conference villages, the idea is to create a hands-on learning environment for security professionals to learn, hack, or break equipment and software that they may not experience on a day-to-day basis. The Gravwell founders have a long history in the ICS space and we believe in the village mission as we think that ICS/SCADA (more so than most industries) could benefit from some disruption and fresh ideas. The ICS Village can be found at many events this year including DEFCON and EnergySec (full event schedule can be found at https://www.icsvillage.com/events).

With the release of Gravwell 2.0, Gravwell customers can now deploy multiple webservers tied to a central storage system. This means you can deploy multiple webservers behind a load balancer for better search performance; the webservers synchronize resources, user accounts, dashboards, and search history behind the scenes so users don’t need to worry about which server they’re actually using.
