An open-source solution that provide good detection and more visibility
The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.
Waleed Omar - PeerSpot reviewer
Provides effective real-time threat detection with potential for cost optimization
Some features such as device control, firewall management, and file analysis are standalone products that we need to purchase separately. If these features came out of the box within the product, it would be much more beneficial for us. Other providers such as SentinelOne include these features in their base product. We attended a CrowdStrike Falcon event where they discussed some shallow AI features, but we cannot see these in our panel yet. We work with different solutions such as Darktrace and SocRadar, where AI features are automatically displayed in our dashboards after release. However, for CrowdStrike Falcon, we cannot see these features.

Quotes from Members

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

Pros

"Asset discovery is good."
"The product is easy to use."
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"Network traffic analysis is highly efficient."
"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."
"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 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."
"CrowdStrike enables the infrastructure managers to visualize all the events and get information about the network."
"Everything we've done with CrowdStrike is due to Arctic Wolf. We don't even need to get alerts from CrowdStrike anymore. It'll send those to Arctic Wolf, and then Arctic Wolf analyzes those and let us know if there's a major issue."
"The solution offers great stability."
"We have seen a reduction to the performance hit to our operating systems."
"The detection and response console is the most valuable feature."
"Cyberattack detection is very good. We use it for detecting different vulnerabilities, such as ransomware, virus, and malware. It is a good product today when compared to Symantec that we used previously."
"The threat intelligence is the most valuable feature."
"Probably the most valuable thing to me is the real-time response piece. The fact that I can connect to an endpoint as long as it is on the Internet, no matter where it is globally. I can remove files from the endpoint, drop files on the endpoint, stop processes, reboot it, run custom scripts, and deploy software. Pretty much no other tool can do all that."
 

Cons

"The incidence reporting could be better."
"The price of this solution is very high and it could be cheaper."
"Sometimes technical issues take very long to get resolved."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"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 could improve by having better integration with some of the newer tools."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"Improvement is always possible. It's challenging to gauge how much future mitigation is provided, especially since we've only been using the product for about one and a half years. Every product faces this challenge because nothing is ever completely foolproof. So, besides relying on technology, we also focus on increasing our staff's awareness of security issues. Feedback from my colleagues suggests that the reporting and dashboarding of incidents could be improved."
"They respond quickly on the weekdays, but the weekend response times are slower."
"Sometimes CrowdStrike changes the GUI, and they need to be better at informing us and providing guidance concerning that."
"The dashboard area must be improved. We have integration with Splunk, and we are creating a dashboard there. Their dashboard area must be up to date. It should have more details and more options to create the reports and things like that."
"The solution isn't known in my market. The brand isn't as recognizable. Their shortcomings are more on the marketing side."
"The technical support could improve because I am in India and the support I receive is from the UK or Australia. It is difficult to manage the time difference. The service could be faster. However, when we do have the support they are knowledgeable."
"The malware analysis could be improved, as that's what we use the solution for the most and that change would make it a better EDR tool."
"They need to strengthen the forensic capabilities of this product, for e-discovery."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"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."
"AlienVault OSSIM is free."
"OSSIM is free."
"AlienVault OSSIM is an open-source solution."
"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."
"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."
"It is an expensive product, but I think it is well worth the investment."
"The price is high in comparison to similar brands."
"The solution isn't very costly; it's affordable."
"The pricing on CrowdStrike is per license. It was about $42 per seat yearly."
"The solution's pricing is great for us."
"Pricing and licensing seem to be in line with what they offer. We are a smaller organization, so pricing is important. Obviously, we would make a business case if it is something we really needed or felt that we needed. So, the pricing is in line with what we are getting from a product standpoint."
"We bought a very small number of licenses, then ran it for a year. We bought a 100 licenses for a year, so we didn't actually do a proof of concept. We just bought them. Then, the next year, we bought 10,000 licenses."
"We pay between $30-50 per user for a yearly license, which is more expensive than SentinelOne or Bitdefender. However, CrowdStrike gives better value for money."
