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.

We need to improve Trellix ESM by making sure that most of the logging devices available in the global market should be covered, and if there is any device which is not covered, there should not be any additional charges for writing the custom parsers on that. We can add some new features regarding AI in the future for Trellix ESM, but the maturity will take a longer time. There are many false positives that happen in an environment during the first couple of months, or around six months, so the system analyst is not able to identify whether the event which has occurred is a true positive or a false positive.

Quotes from Members

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

Pros

"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"Network traffic analysis is highly efficient."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"AlienVault OSSIM's GUI is very user-friendly."
"The most valuable feature is the logging capability."
"Better than other SIEM solutions because almost everything can be integrated."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The product works better than other vendors available in the market."
"The product is worth the price."
"The most valuable feature is the capability to correlate different events from different platforms that we feed into it."
"VirusScan Enterprise provides protection against real-time malware attacks."
"It is user-friendly. The notification part of McAfee ESM is very easy."
"The most valuable feature is that if the scanning does find something, it quarantines it. Then you can decide what you are going to do with it."
"McAfee as a whole is a good solution."
"The solution is 100% stable. We really have had a great time working with it. It hasn't let us down."
 

Cons

"I would advise others to not implement it for any enterprise-level organization."
"The initial setup was not so easy, partly because the documentation was not up to date."
"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"The solution is not scalable."
"The correlation engine needs to be improved."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"AlienVault OSSIM is costly."
"There are always multiple bugs in the product."
"The user interface could be more user-friendly."
"The initial setup is difficult and could improve."
"The disk space needed for events is not clear. In all clients, we had at least more than 100GB free that we could not use."
"Yes, sometimes it seems that versions with major upgrades come with some bugs and regressions that affected stability."
"It is more difficult to operate Trellix ESM than other solutions."
"The solution needs to improve case management. The UI is confusing."
"Tech support is required each time there is a system update of the solution."
 

Pricing and Cost Advice

"The tool's licensing costs are yearly."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is an open-source solution."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"The pricing is fair."
"It is an inexpensive product. We purchase its yearly license."
