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

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

"The initial setup is easy."

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

"The solution is useful for monitoring network devices."

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

"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."

"I have found that it has a good GUI and user-friendly administration."

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

More Nagios Network Analyzer pros

"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."

"The most useful feature is the anomaly detection because it's not signature-based. It picks up the initial part of any attack, like the recon and those aspects of the kill chain, very well."

"One of the most valuable features is all the correlation that it does using AI and machine learning. An example would be alerting on a host and then alerting on other things, like abnormal behavior, that it has noticed coming from the same host. It's valuable because we're a very lean team."

"It provides various dashboards that facilitate the identification of connections and can detect data exfiltration, meaning data sent from your environment to another."

"I like the way that Vectra AI focuses on the internal network. Nowadays, most of the attackers are already inside, and they can be inside for many years before they start attacking. With normal monitoring, it's quite difficult to find them."

"Vectra AI helped our team be more productive and save time. We have less work thanks to it."

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

"The packet-capturing feature is very useful."

More Vectra AI pros

Cons

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

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

"It has an old-fashioned interface."

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

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

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

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

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

More Nagios Network Analyzer cons

"Other alternatives, like Darktrace, have a fancier UI."

"The solution's marketing is not good."

"It does a little bit of packet capture on alert so you can look at the packet capture activity going on, but it doesn't collect a whole lot of data. Sometimes it's only one or two frames, sometimes it does collect more. That's why they have the addition of their Recall platform, because that really does help expand the capability."

"One of the things I am not so happy about when it comes to Vectra is the scoring board."

"I would like to see data processed onshore. Right now, the cloud components, like Office 365, must be processed on servers outside of Australia. I would like to see a future adoption of onshore processing."

"A blind spot that I have is around the ease with which you can automate threat intervention."

"ExtraHop has better features that seem more advantageous when compared to Vectra."

"In comparison with a lot of systems I used in the past, the false positives are really a burden because they are taking a lot of time at this moment."

More Vectra AI cons

Pricing and Cost Advice

"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."

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

"The upfront pricing model that we have would have been more beneficial if it had been a recurring license fee, but that wasn't a massive issue for us. It's fairly priced."

"From a licensing perspective, the Vectra detect platform is pretty doable. Also, the hardware prices are nothing that we're not used to. The stream part is a little overpriced compared to the detect part. The reason is that you need to stream data to detect events anyway, so the data is in there. The only thing that's not available is the UI to be able to look at the stream data, which is also on the appliances but is just not activated. That's mainly the thing that we want to improve on."

"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's pricing is too high. All schools will not be able to afford it. Vectra will only end up targeting higher education and higher value independence purely because of the price. A lot of schools would love to have a product like Vectra AI, but they simply can't because they struggle to even pay the high E5 licensing from Microsoft. When you're up against that, Vectra AI is never going to be within the sector's price range."

"We have a desire to increase our use. However, it all comes down to budget. It's a very expensive tool that is very difficult to prove business support for. We would like to have two separate networks. We have our corporate network and PCI network, which is segregated due to payment processing. We don't have it for deployed in the PCI network. It would be good to have it fully deployed there to provide us with additional monitoring and control, but the cost associated with their licensing model makes it prohibitively expensive to deploy."

"Vectra AI's pricing is cheaper than that of Darktrace."

"The licensing is on an annual basis."
