An affordable product with great integration capabilities

Plixer Core Platform is a valuable feature and a good software. Plixer Scrutinizer uses NetFlow analysis to monitor whatever is there in a network. Price-wise, Plixer Scrutinizer is not an expensive product. Basically, Plixer Scrutinizer is an affordable product. Plixer Scrutinizer is a tool that allows for customization, especially in scenarios where customers need new product features. Plixer Scrutinizer is a tool that can integrate with any other brand or product in the market, so it is not an area of concern.

Quotes from Members

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

Pros

"Nagios Core is very configurable. Whatever you want, you can do it."

"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."

"The poller is really good, I can easily implement new stuff and it is scalable."

"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."

"The most valuable feature is the performance parameters of the system."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."

"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."

More Nagios Core pros

"As a network engineer, the ability to identify what traffic on the link is consuming all the bandwidth at any given time, and provide immediate feedback to the business, is the most valuable feature."

"I honestly don't think there are many areas where Scrutinizer could be improved; it's a pretty robust, out-of-the-box solution."

"We have had many requests to understand in the network which devices are connected to others. Most people don't have this information or are able to establish a map of data flow everywhere around the network. Scrutinizer can really help with this. We are using it to understand who is talking to what, how, and which protocols can help us to improve security and analyze flow."

"Plixer Scrutinizer is an affordable product. Plixer Scrutinizer is a tool that allows for customization, especially in scenarios where customers need new product features."

"Visualization of the network traffic is the most valuable feature. It allows you to drill into information quite quickly."

"The most valuable features of Plixer Scrutinizer are its ease of use, accessibility, and UI."

"The most valuable features of the solution are the ability to track what a device is doing and to go back historically. It is also able to go down to, and identify, very low levels of traffic."

"My boss and I have been very happy with the product."

More Plixer Scrutinizer pros

Cons

"Nagios Core would benefit from aggregations if a particular server goes down."

"Lessening the price point would be an improvement."

"This is the open source product, so it's a toolkit rather than a complete solution."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."

"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."

More Nagios Core cons

"Data retention needs improvement. Data retention is a thing where we are looking for a better way to collect flow data for a longer time to do forensic research on security incidents. By default, data retention is quite low. We need detailed data in safe storage for a longer time, e.g., for a couple of months. An improvement would be a way to export data into a secure long-term storage."

"It would be useful if there was a way to back up the configuration information. E.g., if you wanted to deploy a new instance or disaster recovery, you could quite easily deploy and restore the config, as opposed to having to restore all the NetFlow data. If there was just a button that said "backup config information", that would be good."

"Though Plixer Scrutinizer has network detection and response, it's an area that needs just a little more rounding out."

"We couldn't get it set up properly."

"There was a price lift because previously the product was privately owned, and now there is some external capital in the organization, so pricing could be lower, though, for Plixer Scrutinizer, there is almost no competition at this price point."

"Though Plixer Scrutinizer has network detection and response, it's an area that needs just a little more rounding out. Another room for improvement in the solution is its lack of SaaS offering which some customers were looking for. My company deals in small to medium businesses, mid-market, and some customers wanted the SaaS feature which Plixer Scrutinizer doesn't offer. What I'd like to see in the next release of the solution is for it to have a SaaS offering because my company also deals with educational spaces and smaller businesses that just don't have the staff that can implement this. If there's either a managed service or SaaS-based offering to just make it a little easier for those types of customers, it would be a great addition to Plixer Scrutinizer."

"For updating the Scrutinizer platform, when we have the actual data, it never happens in one day."

"The visual acuity of how it presents data can sometimes be confusing. It takes a bit for people to spin up how to look at the graphs."

Pricing and Cost Advice

"The product is cheaply priced."

"Lessening the price point would be an improvement."

"Nagios Core is a cheap solution."

"We are using the free version of Nagios Core."

"We are using the open-source, unpaid version."

"We are using the free version."

"It's free."

"I would rate the solution's pricing an eight out of ten."

More Nagios Core pricing and cost advice

"We pay our one-off cost for the licenses, per device, in blocks of 50. And then we pay an annual maintenance fee of about $15,000 Australian, which is, at this point in time, about $9,000 US, for those 250 devices. The upfront costs for the 250-license use, were about $50,000 Australian, which is about $32,000 US."

"We have increased the license over time. We have added more licenses as the network has grown."

"We recently bought a license upgrade, so we will integrate more exporters. We upgraded from a 25 exporter license to a 50 exporter license. Therefore, there will be more flows, and this will be an extension. I don't know when we will purchase a faster server, because the server that we have is quite new."

"There is a recurring maintenance fee after the initial purchase or if we want the license upgrade."

"Our entire solution, amortized over five years, is in the vicinity of $40,000 to $50,000 a year."

"It's about €10,000 a year for initial license and yearly maintenance costs. In addition, the hardware costs are about €10,000 once every five years."

"The licensing cost for Plixer Scrutinizer is in the middle. It's not the cheapest, but it's not the most expensive. Its licensing model is based on how many exporters, how many devices export information to the system. Plixer Scrutinizer has different modules you could add such as the security module which would cost extra."

"Compared to some of the other tools we have, it's incredibly reasonably priced."
