Enables cost-effective security management for small businesses
Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

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 security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"What I like about this product, is that it is a fully-fledged solution."
"The most valuable feature is the logging capability."
"The dashboard is the solution's most valuable aspect; it brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on," and the solution works well and allows me to have visibility into anomalous events."
"Asset discovery is good."
"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."
"Better than other SIEM solutions because almost everything can be integrated."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"The product's initial setup phase was not at all difficult."
"Setting up NetWitness is straightforward; there are multiple connectors, including standard and specialized connectors, with enhanced capability to integrate custom applications, and from there you can consider the correlation rules, integrate the different log sources, and easily create correlation rules and backlog reports."
"The most valuable feature is the security that it provides."
"Alerting Module: It provides real-time event processing language on all the logs/packets stream for advanced alerting, i.e., using SQL LIKE statements."
"In my opinion, the solution's most valuable feature is its capacity to monitor network traffic, logs from devices within the network, and network captures. This capability extends beyond logs to include full network capturing."
"It gives the ability to investigate into network traffic in the Net and the organization what we couldn't do before."
"Packet Solution: Allows analyst proactive hunting and alerting on daily sophisticated APTs."
"It gives the capability for the incident response team to correlate logs to identify any kind of problem like malware and incidents in a general sense, both for logs and packets."
 

Cons

"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The incidence reporting could be better."
"The user interface needs to be friendlier across the board."
"They can add more compliance templates."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The biggest thing I always complain about is that the user intake is a very old version."
"It's so hard to configure and explore something new on it."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"An area for improvement would be better automation and more inbuilt use cases."
"They should implement algorithms to digest that data and produce additional, more advanced reporting, alerting and support of internal security teams."
"We have encountered issues with unresolved crashes."
"The implementation needs assistance."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
"Sometimes, it gives me static when integrating Windows-based systems. This solution should trigger a meaningful log or message indicating the reason the user or implementer can't get into the machine."
"The initial setup was complex because it takes a lot of time to complete the implementation."
"The solution should have more integration capabilities with different platforms."
 

Pricing and Cost Advice

"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."
"AlienVault OSSIM is an open-source solution."
"AlienVault OSSIM is expensive compared to its competitors."
"The solution is open source, so it's free to use."
"The tool's licensing costs are yearly."
"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"This is a pricey solution; it's not cheap."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"It is cheap."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"The licenses are good but the cost is very expensive."
"It provides tools to assist in selecting the appropriate license and usage scenarios."
