Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.

Has supported compliance needs for mid-sized organizations but lacks customization and advanced integration
If we pitch Rapid7 InsightIDR against solutions such as SIEMs from Splunk or LogRhythm, it is not as customizable as a SIEM solution is. This is where it can improve if we keep in front the feature sets of a complete SIEM solution. Most common in the market is QRadar, but it is depleting now. It has been taken over by some other products such as Splunk and LogRhythm. If we compare these things with Rapid7 InsightIDR, then there are definitely some gaps that need to be filled. Data retention is also one concern because Rapid7 InsightIDR is cloud-based and operates on a subscription model. Whatever data you want to retain, it has to be paid for separately or it has a cost. Other solutions that are on-premises can have their own infrastructure or they provide some data retention for a month or in some capacity-wise, they provide that solution to them which makes them more attractive.

Quotes from Members

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

Pros

"Support is very good."
"ArcSight is customizable. You can integrate just about anything. I also like the ease of use."
"We utilize ArcSight ESM for real-time threat detection in our organization. We have custom rules that we've developed on top of the WAN services, along with scheduled licensing activities."
"The most valuable features of ArcSight ESM are ease of use and readily usable components."
"The solution has gone beyond signature-based monitoring and analysis and is AI-powered. It is good enough to cover the full range of cybersecurity services."
"The filters and the ability to do what you want are the most valuable features. There is nothing that you cannot do in this solution. It has all the features, which makes it very dynamic."
"When WannaCry attacks I can minimize the damage. My company had no protection at the time. We get alerts in ArcSight and then whenever a user got a copy of WannaCry and the WannaCry malware wants to connect to the mother ship, it alerts me in the ArcSight dashboard, and that helps us a lot. We then just go to the user and erase the malware."
"The tool is good for correlation and aggregation. We use it as a collection platform."
"It improves because several sensors are deployed within the on-premise environment. It can be very efficient if the customer implements and operates it effectively."
"During simulations or demonstrations, the tool generates alerts, providing details such as the specific application, its origin, and potential threats. For instance, it can identify if an application belongs to a known ransomware group. The system rates the threat, offering a clear detection ratio, such as 97 out of 100. It not only identifies threats but also illustrates the associated behaviors, helping us understand the potential risk to a particular endpoint."
"The ability to ingest Office 365 log files, then process them into events and display them on a map."
"The product works well. Stability-wise, I rate the solution a ten out of ten."
"Great coverage of all systems within our network from endpoint to firewall."
"Rapid7's reporting is more robust than Tenable's."
"If you were on other solutions, you would notice that they use agents from third-party, from open-source, from a native OS, or from other tools. Here, however, it is an agent from Rapid7 itself. This adds to the solution's overall capabilities."
"Rapid7 InsightIDR is budget-friendly and has a good market position because not everybody can afford to go for LogRhythm or Splunk or QRadar."
 

Cons

"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."
"In other products, I have found that they use some kind of GUI that is drag and drop. While in ArcSight they use still scripting. They should keep scripting because some people prefer scripting but they should have the option for those who prefer using drag and drop."
"The dashboard looks a bit cumbersome."
"HPE ArcSight has a quite steep learning curve."
"They also could improve the product by integrating user and identity behavior analytics."
"The way that scaling is set up isn't very cost-effective."
"The API integration could be better, and I'd like to see more machine-learning capabilities in the future."
"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."
"There are certain limitations with Rapid7 that I am working on."
"The searching feature in Rapid7 InsightIDR needs to evolve"
"The solution needs improvement in threat intelligence. Increasing the depth of intelligence to help users understand more about threats is a possibility. My suggestion is to expand access to other websites or resources."
"InsightIDR is only available in a cloud version. Some of our customers prefer an on-prem solution because they want to manage the security within their environment."
"Customised alert recipients need to be added to allow better first-line action and quicker response. Configurable honeypots would be a welcome addition."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
"One of the things that could be better is digital forensics. It is there, but it can be better. They could provide more on the endpoint detection level."
"Rapid7 InsightIDR is not intuitive to search for logs. It should be more user-friendly and improve the dashboards. We should be able to use ready-made templates instead of having to build one."
 

Pricing and Cost Advice

"The product licenses are inexpensive."
"There is a license required for this solution."
"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"Aggregation can help a lot in pushing down licensing costs."
"The pricing is great compared to others."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"ArcSight can be a little bit expensive because of the area that we work in and the cost. Licensing is mostly on a yearly basis, not monthly."
"It's a good price, it's one of the cheaper solutions."
"Rapid7 InsightIDR is a cheaply priced product. On a scale of one to ten, where one is very expensive, and ten is very cheap, I rate the product's price at seven or eight."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"The pricing is good, and it is not very expensive."
"The pricing and licensing are competitive."
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"Rapid7 InsightIDR's pricing is reasonable but we have challenges with the Minimum Order Quantity. It is not reasonable for customers who have less than one hundred devices. If they can reduce Minimum Order Quantity, it is good. You have to pay around 5000-6000 dollars per year for the product. The pricing includes maintenance and support costs."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
