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.

Yashokanth Partkunan

Managed Services Engineer at Loop1 Systems

Has supported client needs efficiently but requires deeper analysis features and faster support

The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment. More modification and enhancements are required on the dashboard side in order to make it closer to optimal performance. From observation and feedback from users, they need more functionality related to monitoring, and in-depth analyzing needs to be improved.

Quotes from Members

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

Pros

"Network traffic analysis is highly efficient."

"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."

"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."

"The paid version of the solution has reporting and better scalability options."

"The initial setup is straightforward."

"Asset discovery is good."

"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."

"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."

More AlienVault OSSIM pros

"It supports high availability, which is very helpful."

"SolarWinds is easy to configure, and it provides timely alerts."

"The most valuable feature of this solution is the visibility into both attempted and failed logins."

"The out of the box reports and dashboard. It was easy to trim down these windows to something we could quickly use."

"It has in-depth monitoring capabilities and an easy way for setting up dashboards. I can expand in various areas, or I can reduce areas. It supports different types of breakdowns, filters, and rules. It is very simple for an out-of-the-box type of product. It doesn't take a lot of time to figure it out, which is unlike some of the solutions that I have looked at. It meets all the aspects."

"It performs network behavior monitoring, log monitoring, and disaster recovery monitoring."

"We had to integrate with other teams, and the infrastructure deployment didn't take long. The integration involves learning with different teams, networking, and configuring various network devices and servers. Infrastructure deployment only took one or two days."

"The product's most effective part in improving security stems from the fact that the solution is deployed for event management, log viewing, and information management."

More SolarWinds Security Event Manager pros

Cons

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

"The incidence reporting could be better."

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."

"Sometimes technical issues take very long to get resolved."

"The price of this solution is very high and it could be cheaper."

"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."

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"The solution is not scalable."

More AlienVault OSSIM cons

"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."

"I imagine we will have to develop our own reports soon, this seems to be more cumbersome."

"There are no multiple dashboards which would allow you to see information side-by-side."

"The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment."

"I would like to have a more customizable dashboard."

"The reporting could be more robust. It can be a lot more granular and that will make it a lot more useful in comparison to how it is incorporated at the moment."

"Training for this solution needs to be improved, as new employees are sometimes unfamiliar with the product."

"The solution's technical support is okay, but we don't have an SLA, and sometimes the response times are very slow."

More SolarWinds Security Event Manager cons

Pricing and Cost Advice

"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."

"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."

"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."

"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 tool's licensing costs are yearly."

"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."

More AlienVault OSSIM pricing and cost advice

"The tool is available at a good price for customers compared to other solutions in the market. I rate the product's price as an eight out of ten."

"The pricing model would benefit from having package deals with other SolarWinds products."

"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."

"We do a yearly license renewal. For a year, the solution costs roughly $500,000 USD. There are no costs beyond this yearly fee."

"The price of SolarWinds Security Event Manager is reasonable."

"Licensing is on devices, so if you have many, then this may be high."

"Licenses can only be purchased in blocks of fifty at a time."

OSSIM

SolarWinds LEM, Solarwinds SIEM, TriGeo, Log and Event Manager

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

When TriGeo was acquired by SolarWinds, TriGeo SIM became known as SolarWinds Log & Event Manager. This product is a leading Security Information and Event Management (SIEM) product and log management solution, which provides log collection, analysis, and real-time correlation.
