The solution is useful for monitoring network devices, but the interface is old-fashioned

The solution is useful for monitoring network devices We use it for up-and-down monitoring features. It’s an old solution. It has an old-fashioned interface. The product must provide a compliance testing feature. I have been using the solution for six years. I rate the tool’s stability a ten…

Innovative detection features enhance monitoring

The advantages of the integration are not entirely out-of-the-box. You have to do it manually. When I'm doing tier response, an out-of-the-box solution is not available. You need to have a Linux server, and from the Linux server, you must perform AI tasks, and there is a lot to be handled in the back end. This is a major consideration about them. The recall feature, if it can be placed in some areas instead of the cloud, and charged for, would be better. Recall the storage where you watch all the traffic, and you can recall it and try to analyze it in the back end. It’s cloud-based. If they offer it on-prem, it would be better. I think they have a solution, but I have never tested it, to be honest with you.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The initial setup is easy."

"Network tracking is the most valuable feature of Network Analyzer."

"The network monitoring feature, especially, stands out to me."

"The solution offers very good system monitoring. It's easy to manage your network, as well as your hardware and software. It's really useful."

"The solution is useful for monitoring network devices."

"Its initial setup process is straightforward."

"It is highly customizable and can be integrated well with third-party software."

"The tool's UI is user-friendly, and pricing is affordable. It is very easy to deploy and learn."

More Nagios Network Analyzer pros

"The solution's ability to reduce alerts, by rolling up numerous alerts to create a single incident or campaign, helps in that it collapses all the events to a particular host, or a particular detection to a set of hosts. So it doesn't generate too many alerts. By and large, whatever alerts it generates are actionable, and actionable within the day."

"Scalability wise, we have many sensors, and Vectra AI seems to handle them all very well."

"One of the key advantages for us is we define a 24/7 service around it. We use far more of Vectra alerts than we do with our SIEM product because we understand that when we get an alert from Vectra we actually need to do something about it."

"One of the things that we didn't expect to happen was that our network team also jumped on it faster than we thought. In most cases, if it's a security tool that's working on the network part, they can also use it to find out certain flaws that have been in the system. Certain flaws, related to some legacy stuff, were already there for quite a few years, which they couldn't explain at first, but we could explain them based on the timing of certain things."

"Using this tool for automation has provided more benefits to our processes."

"It gives you access, with Recall, to instant visibility into your network through something like a SIEM solution. For us, being able to correlate all of this network data without having to manage it, has provided immediate value. It gives us the ability to really work on the stuff where I and my team have expertise, instead of having to manage a SIEM solution..."

"Vectra AI generates relevant information."

"The core product provides excellent visibility, but my favorite feature is Vectra Recall."

Cons

"There are some loopholes you need to be aware of from a security perspective."

"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."

"The graphics and reports can be a little bit better."

"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."

"They need to have some automation models embedded in them."

"There is room for improvement on the setup side."

"I think the reports can be improved. They're adopted."

"The bandwidth for its front-end version needs enhancement."

More Nagios Network Analyzer cons

"We would like to see more information with the syslogs. The syslogs that they send to our SIEM are a bit short compared to what you can see. It would be helpful if they send us more data that we can incorporate into our SIEM, then can correlate with other events."

"Some of the customization could be improved. Everything is provided for you as an easy solution to use, but working with it and doing specific development could be worked on a bit more in the scope of an incident response team."

"We are using SMB 3.0, which is an encrypted protocol. When we get some alerts or something, we cannot go deep into the protocol to see what's wrong because it's encrypted. We need to decrypt the protocol in another way, which is quite difficult. We might go back to SMB 2.0 just for this reason, but that's not a good solution."

"Multiple appliances are required for Vectra AI, making it less convenient compared to competitors."

"I would like more integrations with IOCs and threats currently on the Internet. I would also like to know which threats are based on zero-day attacks, current botnets, etc. Therefore, I would like more information on external threats."

"I would like to see a bit more strategic metrics instead of technical data. Information that I could show to my executive management team or board would be valuable."

"One area where there's room for improvement is the absence of a comprehensive TCP recording and replay feature."

"In education as a sector, we are looking at AI a lot in terms of how it can be used as part of the teaching and learning side of things. It would be great to have Vectra AI look at a better way to enhance the security posture related to the AI tools in our portfolio."

Pricing and Cost Advice

"I rate Nagios Network Analyzer's pricing a six out of ten."

"They charge around ten thousand per month for one thousand nodes. That is their overall cost, but it differs on which company you are applying to, whether you are a service provider or an enterprise."

"The solution is cost-efficient."

"The pricing is very good. It's less expensive than many of the tools out there."

"The license is based on the concurrent IP addresses that it's investigating. We have 9,800 to 10,000 IP addresses."

"Their licensing model is antiquated. I'm not a fan of their licensing model. We have to pay for licensing based on four different things. You have to pay based on the number of unique IPs, the number of logs that we send through Recall and Stream, and the size of our environment. They need to simplify their licensing down to just one thing. It should be based on the amount of data, the number of devices, or something else, but there should be just one thing for everything. That's what they need to base their licensing on. Cost-wise, they're not cheap. They were definitely the most expensive option, but you get what you pay for. They're not the cheapest option."

"Vectra's licensing model could scale to our research network, which has multiple, 100-gigabit links."

"Cost is a big factor, as always. However, I think we have a very good price–performance ratio."

"There are additional features that can be purchased in addition to the standard licensing fee, such as Cognito Recall and Stream."

"My company pays for the Vectra AI licensing fee yearly. I know the figure because my company recently renewed the license, and it's okay, at least for the financial sector."

"Vectra is a bit on the higher side in terms of price, but they have always been transparent. The reason that they are this good is that they invest, so they need to charge accordingly."
