Unified log analysis has strengthened incident detection and supports continuous attack simulation
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.
SohailHyder - PeerSpot reviewer
Head Of Cyber Security at Super Secure
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

"I am satisfied with the solution's stability."
"It's a fantastic product and highly configurable, but it needs nothing less than a seasoned cyber security professional with serious engineering expertise and a real desire to provide meaningful use cases."
"The feature that I have found the most useful is that it can be deployed to the cloud."
"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."
"The stability of the solution is very good; it's pretty perfect, actually, as we don't have crashes, it doesn't freeze, there aren't bugs or glitches, and it's completely reliable."
"The most valuable feature of ArcSight ESM is its ease of use."
"The real-time analysis adds value."
"This process has helped to improve our organization because we have centralized the intra-group security equipment logs."
"Features for user behavior analytics and the rules for attack review are good."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"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."
"The technical support is a solid 10 out of 10 as they take the time to answer any questions or problems which may arise in a reasonable time frame."
"This is a great product and the team is very willing to work with companies."
"Simple configuration and automatically syncs to the cloud platform."
"The ability to ingest Office 365 log files, then process them into events and display them on a map."
"I've used other products such as QRadar and other SIEM solutions and I find this solution is much more simplified and user-friendly."
 

Cons

"When we need to consume old events, we have to wait for a long time. ArcSight should improve the database capability to reply to queries faster. It would also be interesting if they implemented network visibility. For example, they could add a feature like NetWitness with a model just for looking through the packets."
"The roadmap is not clear."
"The first limitation is with the ArcSight Data Storage Manager (ADSM). ArcSight's total capacity is currently capped at 12 TB. This becomes an issue if a customer needs a longer real-time data retention period, such as exceeding 90 days or reaching a year or even ten months. Increasing the disk space beyond 12 TB is not currently possible."
"There are SO MANY things you can do in AS, and there is a lack of really in-depth documentation on a lot of it."
"The stability isn't quite perfect. We occasionally run into problems."
"Support is slow and doesn't always have the required skill set to solve the issues."
"They need to fix some bugs and increase the search performance speed."
"The analytics feature is not reliable and needs improvement for more detailed analysis.​"
"The APIs can be further improved in Rapid7."
"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."
"The ability to tune the collector for custom logs would greatly help."
"The reporting is the weakest aspect. There needs to be multi-level grouping for events (for example, group by user and destination). Right now, we can do a group by user and a separate table or group by destination. But I'd be more interested in where a person was logging into instead of who was logging in or where he was logging in."
"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."
"Cloud risk assessment is one area where I think they need a lot of improvement."
"There is a future in AI with Rapid7, however, it is not fully operated. There are certain limitations with Rapid7 that I am working on."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
 

Pricing and Cost Advice

"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."
"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."
"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."
"The product licenses are inexpensive."
"The pricing is great compared to others."
"Pricing is good, I'd rate the pricing a seven out of ten, with ten being low price. It's better than Splunk and IBM QRadar because their pricing is based on EPS."
"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."
"Aggregation can help a lot in pushing down licensing costs."
"The solution has a mid-range price point in the market"
"It is more reasonably priced than other vendors."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"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 is good, and it is not very expensive."
