The alert fatigue and false positive rates have just plummeted, which is really exciting.
empow has a few areas of improvement as with any other technology, such as continuing to drive innovation in the dashboard. While we've been extremely impressed with the dashboard's ease of use, flexibility, ability to drill down deeply, and focus very intently on an area of interest, there will always be opportunities to be more innovative and open it up to a wider audience than just the operations group, for example. With reporting, there is always a desire to have custom reporting for every client of empow. Relative to keeping up with the sheer pace of cloud-native technologies, it should provide more options for clients to deploy their technologies in unique ways. This is an area that I recommend that they maintain focus.

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

Pros

"From a monitoring and incident response perspective, empow is the most valuable asset we have in our toolkit."
"As a result of the automation, we are able to manage SIEM with a small security team. I'm in a unique position where we have been growing the security organization quite rapidly over the last three and a half years. But, as a direct result of the empow transition and legacy collection of tools towards the empow platform, we've been able to keep that head count flat. We've been able to redirect a lot of the security team's time away from the wash, rinse, repeat activities of responding to alarms where we have a high degree of confidence that they will be false positives, adjusting the rules accordingly. This can be a bit frustrating for the analyst when they have to spend hours a day dealing with these types of probable false positives. So, it has helped not only us keep our headcount flat relative to the resources necessary to provide the assurances that our executives expect of us for monitoring, but allows our analyst team to spend the majority of their time doing what they love. They are spending their time meaningfully with a higher degree of confidence and enjoying getting into the incident response type activity."
"The main menu: You can see everything there, what is happening on the servers, and in the logs, you can view more details of each event."
"The asset management of nodes has been a large help in terms of being able to track applications with more detail and have changes made being monitored into one source."
"The USM is a work horse, no matter what devices or the number of logs we throw at it, the system processes them in real time, correlates the events, and alerts on only events that need human review."
"Its powerful correlation engine helps reduce time in manually correlating events."
"AlienVault has provided a nice, unified system for monitoring and reporting."
"The feature that I liked the most is that they have a vulnerability assessment package that comes along with the SIEM solution. So, whenever I find any threat or alert for any of the devices or servers, I could immediately initiate a vulnerability assessment scan on that machine. That is one of a kind. The price at which AlienVault operates is also valuable."
"ATT AlienVault USM support is very good, they respond quickly to our needs."
"The all-in-one source for the needs of compliance has put everything into one location without the need of other applications and tools to accomplish the tasks."
 

Cons

"Relative to keeping up with the sheer pace of cloud-native technologies, it should provide more options for clients to deploy their technologies in unique ways. This is an area that I recommend that they maintain focus."
"One of the problems we had with stability was a problem of our own."
"ROI has not yet been measured."
"I'd like to see built in support to detect more security incidents."
"The next release will include cloud security and it will support a hybrid IT environment, furthermore the OTX has a great added value but it will help when there is more OTX information in the database."
"The reporting aspect could be improved. While there are a lot of different options available, there are still pieces which are missing."
"It needs to be easier to deploy switch monitoring."
"Pay attention to false-positive event automatic correlations."
"Sometimes the log is unclear, and the report is a bit ambiguous."
 

Pricing and Cost Advice

"I don't have to put up with any longer with these hypercomplex licensing agreements. Every time I want to add some additional reporting as a compliance centric or regulatory specific, e.g., GDPR, PCI, or Sarbanes-Oxley, many providers would have an additional license for this, which felt a bit ridiculous to me. With the simplified licensing architecture, there were no hidden "gotchas" down the road with empow. Something I have experienced with other providers that I've worked with in the past."
"With a higher degree of fidelity in the alarms, we were able to avoid adding additional resources to our teams. We take into account the cost of security resources in the market and the significantly higher fidelity from the alarms that are being generated. This drove down our costs with our MSSP. It drove down my cost for human capital internally. It drove down our need to have multiple resources supporting the underlying infrastructure and health and maintenance of empow as a platform from several resources down to one. Therefore, human capital costs were significantly reduced. Our operating expenses were significantly reduced. Our capital costs were significantly reduced while tripling our capacity and our run rate reduced. It was almost a "too good to be true" situation. Fortunately, for us, it worked out very nicely."
"Use the AlienVault team. They are helpful and the documentation that they provide is second to none."
"The licensing fees are dependent on usage."
"Its price is much lower than McAfee ESM."
"Negotiate the best package for your environment."
"The price for this solution is very good, but since the features do not work the price is expensive."
"It's very reasonably priced. It was one of the lowest among the ones I looked at. Licensing is pretty flexible. They can do a two-year or a three-year, even a one-year, perhaps."
"​The vulnerability management solution is worse than buying a Nessus Professional license.​"
"They charge a license based on the storage. ATT AlienVault USM is a less expensive solution than IBM QRadar."
