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

"ArcSight gives us better visibility into threats that were unknown earlier."
"ArcSight ESM helps us stop security incidents by detecting them early before they can cause more damage."
"SmartConnector: Normalization parses raw logs and converts them into CEF (common event format). This is the core of the product."
"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."
"This product has helped us and our customer for monitoring the security of different applications as well as different hardware devices."
"We use ArcSight ESM for log analysis and security alerts. It warns us of threats and then helps us conduct a forensic investigation of a cyber attack or internal incident after it happens."
"The most valuable features of ArcSight ESM are the dashboards, ease of management for anyone, and simple for teams to provide reports related to cyber security. There are a lot of good features that are provided."
"Stable solution with good customer service support."
"Very intuitive and easy to set up."
"I am able to run automated actions based on the output of reports, leaving me extra time to focus on more pressing matters."
"The ability to ingest Office 365 log files, then process them into events and display them on a map."
"The solution provides satisfying native integration features"
"Scalability-wise, I rate the solution a ten out of ten. As a cloud tool, the product is highly scalable."
"The biggest reason why we chose Rapid7 was to gain value in a really quick time. Its deployment doesn't take months. It just takes a few days."
"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."
"The most valuable features have to do with ease-of-use, as it is easy to check the events, investigate suspicious activities, and do forensic analysis, and the web interface is great — very useful and user-friendly."
 

Cons

"It is quite complex and could use a better UI. So the improvement would be a simplification. It is pretty complicated to use. The architecture is not complex but the setup and use are."
"I tried to learn the syntax in order to customize the software (connectors and agents) for a particular device, and it was a nightmare."
"The initial setup could be more straightforward."
"User behavior analytics is too pricey but an essential tool."
"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."
"ArcSight ESM could improve by adding more features and documentation. There needs to be more documentation."
"For somebody who is new and just starting with this product, they find it really tough."
"It would be nice to have it on the cloud so that you can deploy it easily, saving time and resources."
"Inability to get access to compliance reports within the solution."
"I'd like to see a mobile application included and some feature related to the generality of segregation for internal users that access the application."
"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."
"Sometimes, it is hard to get the right queries to use. Currently, the tool lacks a pre-made set of queries."
"It takes time for the product's support team to resolve issues, making it an area of concern where improvements are required."
"If we pitch Rapid7 InsightIDR against solutions such as SIEMs from Splunk or LogRhythm, it is not as customizable as a SIEM solution is."
"I would like to see more development in InsightIDR towards building their SIEM solution and converting it to XDR."
"Tenable Nessus is easier to deal with. It's more efficient and accurate. InsightIDR is heavier than Tenable in terms of performance and scanning. Rapid7 would be much easier to use if it had a network connector like Tenable. Tenable's connector allows continuous monitoring over the B caps."
 

Pricing and Cost Advice

"There is a license required for this solution."
"Aggregation can help a lot in pushing down licensing costs."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"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."
"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 solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
"ArcSight is pretty expensive compared with its competitors. I believe that is fine as it provides value."
"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"The team is very willing to work with companies. My suggestion is to call the Rapid7 sales department and see how they can help.​"
"​Accurately predict your licensing counts as this is a subscription based product.​"
"Licensing is by endpoint and amount of retention time (at least ours is). Default retention was one year, but we are able to push the retention further if needed. There's also a provide-your-own-S3 option for longer retention if you don't want to pay for the additional retention years in your Rapid7 agreement."
"The solution has a mid-range price point in the market"
"Rapid7 InsightIDR is priced very well and is cost-effective."
"The pricing and licensing are competitive."
