BP
Independent Contractor at a comms service provider with 5,001-10,000 employees
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.
CK
Technical Lead at a transportation company with 1,001-5,000 employees
Simplified detection rules and SOAR workflows have improved compliance-focused operations
One improvement I am looking for is silent log source monitoring. If some feed or some host went offline or was not pulling any logs into Google Security Operations, I would want better visibility. Silent host monitoring would make a significant difference because it is very hard to track which host went down, and there are many false positives as a result. I think there is a lot of room for scalability improvements, particularly in the integration of third-party applications. Currently, I have to write a script and use a cloud run function to pull logs. If there were direct ingestion by simply providing an API key and some sort of client certificate, it would be much easier.

Quotes from Members

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

Pros

"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"What I like about this product, is that it is a fully-fledged solution."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"The product is easy to use."
"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 most valuable feature of Siemplify is the playbooks that can be created."
"The playbooks feature in Siemplify is crucial for automation. We've utilized both standard and custom integrations with other security operation solutions, enhancing our flexibility. The user interface is generally straightforward, although recent changes may require some adjustment and Siemplify's integrations and capabilities offer potential support for various compliance requirements."
"Without hyperbole, I have never, in my entire career, encountered a vendor or a vendor community as awesome as Siemplify. Siemplify and the Siemplify Community quite literally made it possible for our SOC to increase almost five-fold in our number of clients and number of analysts and to go from a Monday to Friday 9-5 shop to a 24/7 shop all in the span of under a year and a half and all while continually adding capabilities and improving the services we offer to our clients."
"Google Security Operations helps meet all the important regulatory compliance across all verticals."
"Google SecOps is extremely useful for threat detection and hunting."
"The valuable parts of Google Security Operations include how easy it is to write parsers or detection rules, and it is well-advanced in the analytical part."
"Overall, Google SecOps is a very useful service for security operations."
 

Cons

"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."
"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 should improve the deployment and make it unified like the USM."
"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."
"The incidence reporting could be better."
"They can add more compliance templates."
"The user interface could be improved."
"Building the playbooks could be easier and the integration could improve. It is a difficult process, such as what API connections need to be made."
"We often encounter minor issues that could be improved, but we maintain communication with the developers and submit feature requests. Recently, I requested enhancements such as improved search functionality within playbooks and expanded options for exporting case data."
"I'm inclined to say that I'd love to see some Machine Learning capabilities integrated into the platform, however, I just attended a demo this morning where Siemplify gave a sneak peek into some Machine Learning capabilities that they are currently developing and have roadmapped for release soon."
"The main improvement could be in the accuracy and detail provided in threat descriptions."
"I can give customer service a rating of six because it is very hard sometimes to keep up with the support."
 

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."
"OSSIM is free."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"AlienVault OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"We are using the community version, which can be used for free."
