Network Detection and Response (NDR): What does it mean?

Posted on - by Stephen Tutterow

What is NDR?

This blog will focus on the hottest 3-letter acronym of 2020 & 2021—NDR. Network Detection and Response solutions must address an expanding list of non-malware threats that revolve around data exfiltration, lateral movement, and targeted user attacks. Teams must deploy solutions that learn and adapt to new patterns in real time to ensure they stay vigilant in this changing threat landscape. Plixer Scrutinizer allows network and security operations teams to address both sides of a problem within a single interface.

VeloCloud metadata monitoring in 2020

Posted on - by Stephen Tutterow

I’ve had the opportunity to work alongside two completed VeloCloud deployments over the past 6 months. This blog covers what I’ve learned about the setup and prerequisites within VMware’s VeloCloud interface and Plixer’s Scrutinizer interface for metadata/IPFIX analysis via flow collection. Once setup is complete, I will highlight how Plixer’s Scrutinizer platform uses that data to demystify the process of bandwidth allocation for carrier and edge selection.

4 must-have reports for network traffic analysis

Posted on - by Stephen Tutterow

Where do I start?

We all end up asking ourselves this question as we dive into a new platform and a sea of new processes. Whether your job requires you to seek out issues within the network or hunt for anomalies and threats, having some guidance goes a long way. Plixer’s Scrutinizer platform uses flow and metadata analysis to provide rich context with automatic template recognition, which means little to no upfront configuration. However, I still believe it’s crucial to know where to start because data can be daunting, even when it’s your own. I’ve had a few opportunities to ride shotgun on threat hunting and network slowdown events and in my experience, these reports will allow anyone to bubble up the right issues using Scrutinizer.

Better wireless impression tracking: how Scrutinizer correlates MAC ID, Token ID, RFID, and wireless metadata

Posted on - by Stephen Tutterow

If you use Cisco’s wireless solutions or Aruba Wireless, you already know how important impression tracking is. There are some strong IPFIX elements that Plixer supports for both platforms and one of the benefits becomes correlation of that data with other systems in the network. Jeff Morrison, one of the other engineers here at Plixer, discussed this in his blog last week and I would suggest reading that first.
