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

"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"The initial setup is straightforward."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The initial setup was straightforward. I didn't have any problems."
"Technical support is excellent; they are very helpful and responsive."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The solution is very intuitive, it's easy to set up, is absolutely stable, and has a lot of integration with other security products."
"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."
"I definitely recommend Rapid7 InsightIDR."
"The solution is very cost-effective because they are not charging based on the EPS but on the number of assets."
"The product works well. Stability-wise, I rate the solution a ten out of ten."
"InsightIDR helps us investigate an environment to discover information about incidents."
"Features for user behavior analytics and the rules for attack review are good."
"Integration with threat modeling from the Metasploit and InsightIDR repositories."
 

Cons

"AlienVault OSSIM is costly."
"The solution is not scalable."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"AlienVault OSSIM gives unwanted notifications."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The incidence reporting could be better."
"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"I chose eight out of ten because of the analytical rules; they lack dynamic rules, and also due to the dashboard and reporting part."
"I would like the ability to adjust the threshold of certain existing alerts. Currently the only option is to change the notifications or create my own alert."
"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."
"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."
"The product allows us to make only 30 custom rules."
"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."
"Lacks a mobile application."
"They should add more configuration and security features to it."
 

Pricing and Cost Advice

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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 OSSIM is free."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"The solution is open source, so it's free to use."
"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."
"We are using the community version, which can be used for free."
"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."
"The pricing of the solution depends on the user. But there is a yearly licensing cost."
"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."
"Rapid7 InsightIDR is priced very well and is cost-effective."
"It is more reasonably priced than other vendors."
"​Accurately predict your licensing counts as this is a subscription based product.​"
"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."
"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."
