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

"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"AlienVault OSSIM's GUI is very user-friendly."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"What I like about this product, is that it is a fully-fledged solution."
"The log aggregation and storage provided by InsightIDR has shown no issues with scalability; aggregating over one hundred millions events daily."
"The solution is easy to use, and the interface is intuitive."
"I have seen that Rapid7 InsightIDR provides security to the networks and endpoints in the company."
"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 alerting to drive investigations and remediation has been its most valuable feature, plus the ability to quickly search multiple logs makes investigations easier."
"Log search allows us to dive deep into aggregated logs and query all event types at once.​"
"Enables the use of honey pots, honey users, and honey files to monitor for suspicious patterns."
"Previously, when something happened, such as when a hacker was attacking one of our customers, we were always behind, or we did not know that we were hacked until the ransomware started, but with the Rapid7 solution, at every step, we could online see what a person was doing, and we could prevent ransomware."
 

Cons

"The user interface could be improved."
"AlienVault OSSIM gives unwanted notifications."
"The initial setup was not so easy, partly because the documentation was not up to date."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"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 initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The biggest thing I always complain about is that the user intake is a very old version."
"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."
"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."
"The APIs can be further improved in Rapid7."
"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."
"Currently, it lacks the functionalities provided by Rapid7's User Behavior Analytics (UBA)."
"The interface for doing investigation needs to be enhanced with minor improvements that would make it more useful."
"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 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."
 

Pricing and Cost Advice

"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."
"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 licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"We are using the community version, which can be used for 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."
"AlienVault OSSIM is an open-source solution."
"We are using a free version of the solution. If you purchase a license there are more features available but the price is a little high. The solution should be cheaper to allow more customers to be able to afford it."
"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."
"The solution has a mid-range price point in the market"
"It is on a yearly basis. For our own company, for about 250 users, it was 16,000 euros a year."
"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."
"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."
"It is more reasonably priced than other vendors."
"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."
