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 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 initial setup is easy."

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

"The solution is useful for monitoring network devices."

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

"Its initial setup process is straightforward."

More Nagios Network Analyzer pros

"The fact that we get the visualization of what's happening on our network, which is a way of improving our security in-depth is most valuable."

"We particularly like the user experience around the dashboard, which we find to be much more straightforward than the dashboard of some of the competitive products... Vectra is a really easy system to understand and use to prioritize where we need to focus our security resources."

"The packet-capturing feature is very useful."

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

"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."

"Some valuable features of Vectra AI are that it is very intuitive and that there are only a small amount of false positives. Therefore, it's an effective solution."

"What I like best about Vectra AI is that it alerts you about suspicious activities."

"It's important for us that the user interface is easy to understand and that is the biggest benefit we see from Vectra AI."

Cons

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

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

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

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

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

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

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

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

More Nagios Network Analyzer cons

"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."

"Some of their integrations with other sources of data, like external threat feeds, took a bit more work than I had hoped to get integrated."

"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."

"For S&D account scans, it would be easier if Vectra AI could triage with users. If a client uses a lot of accounts, then it could indicate that these accounts are benign, for example. That would help a lot."

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

"One of the things that we are missing a bit is the capability to add our own rules to it. At the moment, the tech engine does its thing, but we have some cool ideas to make additional rules. There should be an option in the platform to add custom rules, or there should be some kind of user group where we can suggest them for the roadmap and see if they get evaluated and get transparent communication on whether they will be implemented in the product or not."

"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."

"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."

More Vectra AI cons

Pricing and Cost Advice

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

"The solution is cost-efficient."

"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's pricing was 50 percent lower than the other vendors shortlisted."

"At the time of purchase, we found the pricing acceptable. We had an urgency to get something in place because we had a minor breach that occurred at the tail end of 2016 to the beginning of 2017. This indicated we had a lack of ability to detect things on the network. Hence, why we moved quickly to get into the tool in place. We found things like Bitcoin mining and botnets which we closed quickly. In that regard, it was worth the money."

"The pricing is high."

"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."

"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."

"The solution is low-cost and affordable."

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