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.

I do not have any areas for improvement in ArcSight Enterprise Security Manager (ESM) as I have not delved deeply into it; overall, it is a good package. I would like to see the detection and response features included in the next release of ArcSight Enterprise Security Manager (ESM), as security orchestration and automation are increasingly important.

Pros

"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."
"From a monitoring and incident response perspective, empow is the most valuable asset we have in our toolkit."
"The feature that I have found the most useful is that it can be deployed to the cloud."
"The reports that we are from getting from ArcSight are very valuable. The reporting in ArcSight is good. Our regulators ask us for the reports on a regular basis, and we have been able to provide the required data. Its overall functionality in terms of log analysis and the speed at which it does that is also valuable. It is very quick. Whatever alerts we had configured were extremely fast. We immediately get alerts when there is unauthorized access or unknown access, or even positive access. This is where we found the difference between ArcSight and other solutions."
"ArcSight functions to integrate all network and security logs, and it's very easy to use so real-time monitoring has become easy by implementing active channels with all correlated alerts."
"Correlation and data normalization via CEF: The speed of ArcSight's correlation engine, together with data enrichment, makes it a great tool for exploring vast amounts of data."
"It greatly changed our work habits in the organization allowing us to not only trace back security threats, but also to generate usage trends, discover anomalies and so many other usages."
"ArcSight is better than them all when it comes to filtering, normalization, aggregation, dashboards, reporting and correlation, multi-tenancy and custom devices support."
"The product's log management and event management capabilities are excellent."
"The most valuable features are flexible setup of the architecture and large coverage of devices."
 

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."
"It's very expensive in its licensing model."
"The deployment typology could be improved. If you want to scale across all the different lines of businesses, it should be easy to do that and it's not."
"The correlation engine effectively connects different events, significantly improving our detection reach. However, limitations exist with non-default alerts, where additional costs arise for integration."
"I rate ArcSight three out of 10. I would never recommend it."
"I tried to learn the syntax in order to customize the software (connectors and agents) for a particular device, and it was a nightmare."
"Could benefit from a more modern interface."
"Best SIEM product but it's high on pricing and licensing."
"What could be improved in ArcSight Enterprise Security Manager (ESM) is its analytics feature."
 

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."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
"The licensing cost is affordable if you get an enterprise license. The licensing is based on EPS, so you can probably provide a package of license for multiple ESMs with their correlational end fees. It is cost-effective."
"​It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders.​"
"The pricing is great compared to others."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
"Aggregation can help a lot in pushing down licensing costs."
"It's a good price, it's one of the cheaper solutions."
"The pricing model is expensive compared to open-source alternatives."
