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.

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 recommend it due to the experience of the people running it."

"You can customize the dashboards as well as the reporting."

"AlienVault OSSIM's GUI is very user-friendly."

"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."

"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."

"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

More AlienVault OSSIM pros

"InsightIDR’s ability to process millions of transactions per day, and to notify me of the most critical ones, is priceless. InsightIDR has the alerts tuned, and has the ability to quickly drill down to determine the threat level."

"Dashboards, including the main screen, provide much-needed information at a glance, without hours of coding and sifting through logs to find it. In case of an actual security incident, I have faith that insightIDR has retained all logs in a secure manner that prevents log tampering as well."

"The alerting to drive investigations and remediation has been its most valuable feature."

"The solution is easy to use, and the interface is intuitive."

"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."

"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."

"It improved my organization by building a security alerting program."

"Rapid7 is easy to use and deploy. It is a simple solution and has easy data pulling."

More Rapid7 InsightIDR pros

Cons

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"They can add more compliance templates."

"Lacking in depth of reporting."

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"I don't like to work on OSSIM because it is unpredictable."

"AlienVault OSSIM’s configuration and integration could be a little easier."

"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."

"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."

More AlienVault OSSIM cons

"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."

"Rapid7 doesn't integrate well with all our security tools from various vendors, so we plan to switch. Many of our solutions work with Rapid7, but some do not. We are already searching for a replacement already."

"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."

"There are certain limitations with Rapid7 that I am working on."

"If we pitch Rapid7 InsightIDR against solutions such as SIEMs from Splunk or LogRhythm, it is not as customizable as a SIEM solution is."

"The searching feature in Rapid7 InsightIDR needs to evolve"

"Currently, it lacks the functionalities provided by Rapid7's User Behavior Analytics (UBA)."

"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."

More Rapid7 InsightIDR cons

Pricing and Cost Advice

"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."

"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."

"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."

"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."

"AlienVault OSSIM is an open-source solution."

More AlienVault OSSIM pricing and cost advice

"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 pricing is good, and it is not very expensive."

"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."

"It is a reasonably priced solution."

"I rate Rapid7 InsightIDR's price a four on a scale of one to ten, where one is cheap, and ten is expensive."

"I am sure that there are cheaper products out there, but none that meet so many of our needs whilst maintaining stability and usability."

"The pricing and licensing are competitive."

Overview

AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.

AT&T

Parsing hundreds of trivial alerts. Managing a mountain of data. Manually forwarding info from your endpoints. Forget that. InsightIDR instantly arms you with the insight you need to make better decisions across the incident detection and response lifecycle, faster.
