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

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

"The solution is useful for monitoring network devices."

"Its initial setup process is straightforward."

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

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

"The initial setup is easy."

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

More Nagios Network Analyzer pros

"It has reduced the time it takes to respond to attacks. That comes back to the proactive point. It makes us able to lower down in the kill chain, we can react now, rather than reacting to incidents that happened, we can see an instant, in some cases, as it's being implemented, or as it's being launched."

"Vectra AI is the best. It is a major product in our cybersecurity."

"The automatic filtering that they provide is valuable. The logic inside that makes some detections instead of us is very useful. We are confident that if we are just looking into it and there is nothing, nothing could happen."

"We discovered a lot of things in our network and are correcting several misconfigurations. We are learning how some apps work together and how some things shouldn't happen. It's also easier for us to identify the source of a brute force, whereas before, we didn't even know we had a brute force."

"It keeps up with the network traffic, which is a good thing. It provides more context to plain alerts compared to using an older system. So, it helps an analyst reduce the information overload."

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

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

"The solution provide visibility into behaviors across the full lifecycle of an attack in our network, beyond just the Internet gateway. It makes our security operations much more effective because we are now looking not just at traffic on the border, but we're looking at east-west internal traffic. Now, not only will we see if an exploit kit is being downloaded, but we would be able to see then if that exploit kit was then laterally distributed into our environment."

Cons

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

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

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

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

"It has an old-fashioned interface."

"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."

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

More Nagios Network Analyzer cons

"They use a proprietary logging format that is probably 90% similar to Bro Logs. Their biggest area of improvement is finishing out the remaining 10%. That 10% might not be beneficial to their ML engine, but that's fine. The industry standard is Zeek Logs or Bro Logs, or Bro or Zeek, depending on how old you are. While they have 90% of those fields, they're still missing some fields. In very rare instances, some community rules do not have the fields that they need, and we had to modify community rules for our logs. So, their biggest area of improvement would be to just finish their matching of the Zeek standard."

"We have had a few issues with the integration of Vectra AI with EDR. Some filters have not been working. We've also had issues with the brain not being powerful enough."

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

"The main improvement I can see would be to integrate with more external solutions."

"Neither Vectra nor Darktrace have a function like a status health check on my log sources and traffic sources."

"There is room for improvement in the documentation. We would like to have more details on how it detects what we see."

"There could be an option where Vectra manages the solution remotely, and when there is an attack, there could be a notification center to give us information about the attack."

"Vectra Recall could be utilized much more, and I'm seeing some indications of that today with the investigative components. I use the Visualize feature to visualize components and dashboards a lot. I'm interested in new ways to build automated searches or having them leveraged already from Vectra."

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."

"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."

"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."

"Its cost is too much. It's an investment that we can afford. It's a lot, but it's worth it."

"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."

"From a pricing perspective, they are very commercially competitive. From a licensing perspective, just be conscious that some of their future cloud solutions come with additional subscriptions. Also, if you're outside of the US, you will get charged freight for the device back to your country."

"It is an expensive solution, but it's not the most expensive we've seen. We also know how much we're going to pay, unlike with some other providers where all of a sudden our license explodes."

"The pricing is high."

"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."
