Nyansa Releases Voyance IOT Security

Recently, I was invited into the Nyansa office to take a look at something new being released. With the growth of IoT devices on networks, Nyansa saw an opportunity to provide a comprehensive set of security and device analytics of IoT devices.

Innovations with IoT devices have resulted in shadow IT deployments in enterprises, hospitals, higher education, and more. Many of the IoT devices solve a critical business need but the devices themselves often lack sophisticated security implementation and are susceptible to vulnerabilities.

Voyance IoT Security leverages the same platform driving the Voyance analytics platform. Included with Voyance IoT Security is:

  • Classification of IoT devices
  • Baselining for behavior assessment
  • Automation of security enforcement through 3rd parties such as Cisco ISE or Aruba Clearpass
  • Utilization tracking for further anomaly detection

Nyansa is coming out of the gate with multiple 3rd party integrations which include:

  • NAC and identity systems: Cisco ISE, Aruba/HPE ClearPass, FreeRADIUS, Microsoft RADIUS
  • Security threat control platforms: Cisco’s Platform Exchange Grid (pxGrid). Voyance is a certified solution on the Cisco pxGrid ecosystem
  • Wireless LAN: Cisco, Aruba/HPE, and Extreme Networks
  • CMDB: ServiceNow native integration
  • SIEM: Splunk and others via extensible Voyance platform APIs
  • Netflow

CTS 141: Analytics Data & Wi-Fi

Nyansa provides visibility into your Wi-Fi network. What can you do with it?

Analytics Data & Wi-Fi

Coming off Mobility Field Day 3 (MFD3), Nyansa brings a couple of updates. There’s a lot of data collected and presented onto the dashboard. What could be challenging is understanding all the data you’re able to see. And it’s not just data from the Wi-Fi equipment. Nyansa’s product will gather information from other systems of your network such as RADIUS servers, DNS servers, and other data collected from SPAN ports.

As we all know, Wi-Fi issues are often not Wi-Fi at all. Collecting this much data really gives you a broad look at how the network is performing for the clients.

Where Nyansa can shine further is by providing data correlation to show you what’s the most critical issue or most impact there is on the network. The data is there in the dashboard but if there’s specific troubleshooting you’re trying to perform, you can dig into further based on clients, APs, DNS servers, etc.

Full Client Experience

What are we trying to get at with all this data collection and analytics? We want to understand how the clients are doing on our Wi-Fi networks. Down from Layer 1 and 2 all the way up to the Application performance. All these stats are collected within Nyansa and analyzed.

Nyansa now has the a client agent which can be installed on macOS and Windows. So much of the data we have been seeing from many solution providers is the point of view of an access point. Now with a Nyansa client agent, we can get a full picture of how clients are performing.

The ability to look at this information as a third party rather than from the vendor’s point of view can sound compelling. In a way we can actually begin holding various vendors responsible for their claims or help to improve client drivers, for example.

White Papers

Where Nyansa can really stand out is by providing white papers containing analysis of how Wi-Fi is performing based on vendor/drivers/applications and more. Recently, Nyansa released information gathered across their client base which shows the impact of the Cisco and Apple partnership. Do we see better roaming with Apple devices because of this partnership?

This is the kind of data which can create an impact in the industry. It might not be the actual direction Nyansa wants to go as a company but that type of information is at their grasp.

Final Thoughts

Nyansa collects a mind blowing amount of data. Where they can improve is in providing better root cause analysis to help point an operator to an actionable result. Having this amount of data at your fingertips allows someone to get detailed information into how their clients are interacting with the network and how that experience is for the user. Where Nyansa may have a missed opportunity is in analyzing different vendors, drivers and even security. We haven’t really seen Nyansa utilize AI to the extent with other vendors but there’s potential. Overall, more information collected the better but can lead to information overload if not handled properly.

Wi-Fi Analytics with Nyansa Voyance

I wanted to look back at what Nyansa has been doing with Voyance since Mobility Field Day 2. Nyansa has been around since 2013 and their focus has been on using network analytics to drive next steps with troubleshooting and trending Wi-Fi data.

To review Voyance, I was able to get access to a demo account. Within the product I grabbed many screenshots to share with you. The information presented is interesting and getting to root causes of various Wi-Fi issues is very helpful.

The Recommendation Engine is an interesting view to look at Wi-Fi issues.

A new addition to Voyance is the Service Desk view. This is for your help desk or service desk folks to view different clients and what issues they may be having.

Nyansa added a global view to the dashboards. If there are multiple sites you have to manage you can overlay them on a map and have quick views into any potential problems. All looks good here.

Charts are a great way to represent data. This is viewing a specific AP.

CTS 071: Wi-Fi Analytics with Nyansa

Our special guest, Anand Srinivas of Nyansa, joins the show to discuss Wi-Fi analytics with their platform Nyansa Voyance. As many organizations are shifting towards getting data usage on the Wi-Fi networks, Nyansa helps fill that void. Anand provides us his insight into analyzing data from our wireless networks.

Wi-Fi Analytics with Nyansa Voyance

Anand Srinivas is the co-founder and CTO of Nyansa, headquartered in Palo Alto, CA. He has his masters and PhD from MIT in wireless and algorithms. Anand has held previous roles at Airvana, Plexxi, Overture and now finally at Nyansa. The focus of Nyansa is to enable enterprises in different verticals to get a handle and insights into user experience on wireless networks.

Anand’s team takes a look at various wireless client transactions with the network, applications, etc. and analyzes all of the collected data to bring user experience into a visual dashboard.

I wanted to bring Anand onto the podcast to talk about Wi-Fi analysis because of this trend where many organizations are trying to get more data out of the network and what the users are doing on that network.

Here are the topics we talk about on the podcast:

  • How Nyansa gets visibility
  • Taking the client perspective
  • Looking across the entire stack
  • Using real clients transactions as ‘sensors’
  • What is “network analytics”, “big data”, “machine learning”, etc.?
  • Every vendor says they do analytics. How do you define or view analytics differently? Or do you? What makes Nyansa unique in this space?
  • How do enterprises justify the cost or value of your analytics system?
  • What packets, fields are analyzed by Nyansa to perform the analysis?
  • Interesting story from people using Nyansa.
