Enables cost-effective security management for small businesses
Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

Centralized threat hunting has improved alert accuracy and simplifies incident investigations
I would say there are two areas for improvement: the reporting dashboard that provides insights or reports weekly or monthly lacks detailed information about how logs are being ingested. While the details are there, they could be more concise and easier to understand for any level of authority. The second area is alert tuning; compared to Microsoft Sentinel, Rapid7 InsightIDR provides fewer alerts with more static alert functionality and lacks dynamic alerting exposures. There could be improvements to learn from past alert activities for more dynamic alert configurations. These two areas are the main areas for improvement; everything else is good.

Quotes from Members

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

Pros

"You can customize the dashboards as well as the reporting."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"I have deployed it widely because I find that it gives value for money."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"Great coverage of all systems within our network from endpoint to firewall."
"The solution is very stable and works very well for what I need it to do."
"Rapid7 InsightIDR is budget-friendly and has a good market position because not everybody can afford to go for LogRhythm or Splunk or QRadar."
"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."
"I've used other products such as QRadar and other SIEM solutions and I find this solution is much more simplified and user-friendly."
"It is a very stable solution."
"It gives all the advantages of a SIEM, however, using clever AI, it looks for patterns of behavior rather than just flooding me with all the alerts."
"The solution provides satisfying native integration features"
 

Cons

"The initial setup was not so easy, partly because the documentation was not up to date."
"The biggest thing I always complain about is that the user intake is a very old version."
"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"AlienVault OSSIM gives unwanted notifications."
"I don't like to work on OSSIM because it is unpredictable."
"ArcSight works better than AlienVault right now."
"It takes time for the product's support team to resolve issues, making it an area of concern where improvements are required."
"The searching feature in Rapid7 InsightIDR needs to evolve"
"One thing that springs to mind is easier API integration with ITSMs. We are evaluating a new ITSM and I would like to have InsightIDR create a ticket when an attack is identified, and the ticket would be closed in InsightIDR when the ITSM resolution is completed. This would take out the "single point of failure" we currently have, if the email recipient is somehow absent, in recording the risk appetite for the incident and the actions taken to mitigate or not."
"Rapid7's customer support is awful. They didn't respond at all."
"The main problem lies in the processes within the client's operating systems."
"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."
"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."
"The APIs can be further improved in Rapid7."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
"The solution is open source, so it's free to use."
"We are using the community version, which can be used for free."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"​I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability.​"
"Licensing is straightforward. If, for some reason, you don’t meet the minimum licensing requirements, there is a third-party managed service that can help."
"The pricing and licensing are competitive."
"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."
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"Rapid7 InsightIDR charges us based on the endpoints we connect to."
"It is more reasonably priced than other vendors."
