Has supported real-time event detection and reporting accuracy while database integration has required extra effort
Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time. However, currently, it is not giving many challenges.It is difficult to integrate NetMon with other databases. We can customize NetMon's monitoring views, but it is done by the team who handles it, as it is outsourced.

Unified monitoring has improved end-to-end visibility and reduced detection time across apps
When we have too many detectors in place for one particular app, such as when I have created 50+ detectors through my account, the entire page becomes a bit loaded when creating the 51st detector, feeling heavy and taking time to load. Additionally, it throws random errors; for example, when we try to save one detector, it might throw some random error which is not even related, with something else being wrong, not that particular error, but the underlying root cause might be different. Sometimes the error is just "some problem occurred," and we are not able to point out what the real cause is. This mainly happens when we have too many detectors or too many alerts in place rather than a standard number. One more thing is in the alert rules; if we have a main general alert, and instead of creating a new detector, we are adding a new rule under one detector, when the number of rules also increases, such as when we have 10 or 15 rules under one generic detector, that again creates the same kind of problem, taking some time to save that particular newly added rule, and it might not save at times, just keeps on spinning. Those are the two drawbacks which I spotted recently; other than that, everything looks perfect.

Quotes from Members

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

Pros

"The analytics feature is the most valuable feature."
"Visibility is a valuable feature, the ability to see even if the traffic is not going into the firewall"
"LogRhythm NetMon's most impressive feature is that it's a bundled package, so you're not just relying on monthly data; you get a six-month view for more comprehensive indicators of compromise. This dual approach is precious. We implement LogRhythm NetMon in our cybersecurity strategy mainly for compliance and correlation of network, user, and decision activities, particularly for network firewalls and access control."
"It is a stable solution...It is a scalable solution."
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
"The initial setup is straightforward because we can deploy an open server."
"NetMon's best feature is traffic analysis."
"It has a very strong artificial intelligence engine."
"The vibrant dashboards are valuable."
"What I appreciate most about Splunk Observability Cloud is the correlation feature, specifically the ease of correlating logs and issues to those traces to see where within the path of the business function is failing."
"The solution's most valuable aspect is its ability to get information about all of the security measurements in my environment."
"The most valuable feature in this solution is the log searching."
"The most valuable thing that we have seen within our group is the ability to ingest all this raw data and have it organized in a certain way so that different groups can get effective alerting from this massive amount of raw data that is out there."
"Detectors are a powerful feature."
"I manage six tools, but Splunk Observability Cloud is one of my favorites, and I aspire to build my career specializing in it because it has great features, more attention in the market, and is a relatively new tool with promising growth."
"We utilize the APM and auto-detectors, as the core metrics and core alerts are available for us, which are the features of Splunk Observability Cloud that I appreciate the most."
 

Cons

"Could use a topology diagram which would help get an exact visual."
"Some of the automated tasks we can perform on QRadar cannot be performed on LogRhythm because the solution has limitations."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
"The main concern is that LogRhythm has not improved NetMon but instead introduced a separate product, which many customers, including us, would prefer to be integrated into a single platform for easier management."
"Sometimes it's hard to find the network devices' self-audit logs."
"LogRhythm NetMon's pricing model is an area of concern that should be made a little bit cheaper in comparison to the other players in the market currently."
"There is an issue with tunneling in relation to how the connectivity is established between the end devices and where NetMon is installed. On the console, I often observe that there's a difference of a few seconds or maybe a minute, and this lag time should not be there."
"The platform's integration features often need to be improved."
"They do not have all the features that I expect right now."
"The cost needs to be re-examined. It's extremely expensive to run. It's also expensive to expand. That's the number one complaint all of my customers have when it comes to Splunk. It's way too expensive compared to other solutions."
"If a customer utilizes third-party tools and wants to forward data from Splunk Observability Cloud, seamless integration would be beneficial."
"I've only experienced downtime, crashes, or performance issues when it isn't configured correctly."
"The feedback is that Splunk Observability Cloud is forcing me to modify my logs that I am ingesting in Splunk Observability Cloud in a specific format."
"The monitoring of workloads when using SignalFx could be improved."
"The implementation can be more user-friendly."
"In the next release, I would like to see more integration with other solutions."
 

Pricing and Cost Advice

"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."
"The product is expensive for smaller companies."
"I don't have visibility into the pricing of LogRhythm NetMon as it's handled through our commercial partnerships."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
"NetMon's licensing costs about $85k per year, with some extra costs for support."
"Pricing is okay. There were some competitors that were extremely expensive and there were some which were really inexpensive but LogRhythm stayed in the middle of them."
"Splunk Observability Cloud is expensive."
"The price of Splunk APM is less than some of its competitors."
"It appears to be expensive compared to competitors."
"Splunk APM is a very cost-efficient solution."
"The solution's pricing is costly."
"The product is a bit expensive considering the competition but the company may negotiate the price."
"Licensing cost is the biggest argument I get from those divesting from Splunk. There are those within our organization who say we are going to go to other tools since Splunk is too expensive."
"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
