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

"The paid version of the solution has reporting and better scalability options."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"Network traffic analysis is highly efficient."
"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."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"With AlienVault you get everything in one box."
"This solution integrates easily and very well with other technologies."
"The tool's effectiveness depends on how you define your log sources. To build visibility of incoming and outgoing traffic, you need logs from perimeter defense, firewalls, web application firewalls, and endpoint protection. With good traffic visibility, incident response time is really quick."
"The solution's technical support is great."
"It can be easily deployed with the other solutions."
"We are quite happy with the product and its stability, but the problem is the lack of support, which is one of the major issues that we are facing."
"It blocks the things which are not to be allowed. It has an adaptive mode where it learns for itself."
"The solution is 100% stable. We really have had a great time working with it. It hasn't let us down."
"We now have a better view of our security posture from an external and internal point of view."
 

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"The user interface could be improved."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Sometimes it takes very long for your issue to get resolved."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The user interface needs to be friendlier across the board."
"I would like to see good analytics in future releases."
"It is more difficult to operate Trellix ESM than other solutions."
"McAfee is no more providing security updates on this product, and the enhancements to this product seem to have stopped. Moreover, we don't get proper support, and we struggle to get its support. It would be good if they can add some AI engine and out of the box use cases because it is currently limited to the same scenario and the same setup. I have done a POC for Securonix, LogRhythm. These products are much more ahead as compared to McAfee ESM. They have included multiple modules in the same solution. Correlation is very easy. If McAfee ESM can improve, especially in such implementations, then I believe it would be much better."
"Yes, sometimes it seems that versions with major upgrades come with some bugs and regressions that affected stability."
"McAfee has many issues with integration. I am looking for an end-to-end integration such as EDR, and Next-Generation SOC 2.0."
"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."
"The support from McAfee ESM could improve. They could improve the speed."
"There's no software support from McAfee."
 

Pricing and Cost Advice

"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
"AlienVault OSSIM is free."
"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."
"The solution is open source, so it's free to use."
"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."
"When compared to IBM Security QRadar and other similar platforms, the pricing of McAfee ESM is reasonable and comparatively less expensive."
"The cost is dependent on the customer's environment and requirements."
"You should buy the distributed option instead of the all-in-one for environments with more than 1000 end points."
"The pricing is good, and they are competitive compared to providers such as RSA and IBM QRadar."
"We pay for our licensing fees on a yearly basis, and there are no costs in addition to the standard licensing fees."
"We renew our license annually."
"The price of McAfee ESM is higher than some of the other solutions. There are additional features that can be added at an additional fee."
"The cost is all included. The finance department handles the financial part, and we mostly don't get involved in it."
