Excels at performing regression and correlation on the data
ArcSight is a legacy technology, and many customers want AI-powered technologies integrated with it. That hasn't been done yet, but ArcSight needs to catch up with the newer solutions and technologies available in the market. It can't just rely on the legacy technology from 2010 or 2012. You can't run that in 2024. It's a legacy technology with its own limitations. Customers often face issues that other software or newer solutions can resolve easily. That's the main challenge we face from customers right now. So, the only concerns are that AI needs to be integrated and scalability improved. Those are the main areas to be improved.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"Once the rules are defined, it is capable of detecting minute changes in the systems, which are effectively based on the entries in the log.​"
"The solution is pretty stable."
"I would rate the ease of use for new users an eight out of ten, with ten being easy to use. It is a good tool."
"Once the rules are defined, it becomes easy to detect changes and generate automated logs."
"On the positive side, ArcSight ESM's performance was excellent. It was very fast when writing queries. It provided good performance monitoring and had built-in rules to show which rules triggered most often and impacted performance. This performance monitoring was well-implemented."
"The tool sends an automated mail to all the operators, which makes it easy to share the information and reporting.​"
"Feature-rich solution which provides better network visibility for improved security"
"​It is a vital tool for live monitoring and helps us to understand the traffic alerts of any major issue on the network, thereby reducing hacking attempts."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"ArcSight ESM is lacking cloud scalable technology."
"ArcSight is incredibly complex when configuring and deploying, and if your organization doesn't know what they want and what they need, ArcSight will be a challenge for them."
"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery."
"​In certain cases, this product does have false positives, which the company should work on."
"The way that scaling is set up isn't very cost-effective."
"I would like for them to integrate mobile devices. Integration or any kind of functionality which will act as a substitute for IBM so that we can really track our mobile devices as well as look at SIEM."
"The stability isn't quite perfect. We occasionally run into problems."
"The initial setup is very complex. We had to architect a deployment which allowed us to incorporate an ever growing number of customers into our hosted instance of ArcSight."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"The pricing is great compared to others."
"​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.​"
"HPE ArcSight pricing might be more expensive than other SIEM solutions, but in my opinion it has powerful features and great flexibility in developing complex use cases."
"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"Price-wise, ArcSight ESM was a bit high compared to competitors, which factored into our decision to switch to Splunk. It couldn't cover all our business needs for what we wanted to implement."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
"The solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"It’s a single license platform."
