HarshBhardiya - PeerSpot reviewer
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 initial setup is straightforward."
"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."
"With AlienVault you get everything in one box."
"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."
"The most valuable feature is the logging capability."
"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."
"The most valuable aspects of CrowdStrike Falcon for me are its device observability, identification, and software and OS recognition."
"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."
"I like the vulnerability assessment and proactive hunting features of CrowdStrike Falcon."
"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."
"This solution consistently releases improvements. They have communicated their next two years of development which is powerful and covers all of our needs."
"Its integration capability is valuable. It integrates easily with any OS."
"It's ability to do threat hunting is really great, quite robust, and even allows you to do hygiene stuff."
"One of the most valuable features of CrowdStrike Falcon is when there are upgrades there are no additional fees."
 

Cons

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"They can add more compliance templates."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The user interface could be improved."
"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."
"The solution needs more integration with cyber intelligence systems."
"They respond quickly on the weekdays, but the weekend response times are slower."
"The console is a little cluttered and at times, finding what you're looking for is not intuitive."
"Unfortunately, native applications are not supported."
"A year and a half ago or more, if you put in a support request by email, then it wasn't timely addressed. It could be a day to three days before you received a response, which was a bit frustrating. There was a lot of customer feedback around this issue, which has been greatly refined."
"The pricing structure should allow for some flexibility."
"I would rate it an eight out of ten. It does what it needs to do but there's always room for improvement."
"I would like a centralized deployment where I could roll out or push it to all endpoints."
"CrowdStrike should add support for ransomware protection."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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 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."
"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."
"OSSIM is free."
"AlienVault OSSIM is free."
"The tool's licensing costs are yearly."
"CrowdStrike Falcon can be more expensive than some competitors, and its base price doesn't cover every feature."
"While CrowdStrike Falcon offers significant security benefits, its high price point might make it prohibitively expensive for many small and medium-sized businesses, including companies like ours."
"We are on an annual subscription for the solution. There are not any additional costs."
"CrowdStrike Falcon offers excellent value for the money for our organization, particularly given our lean IT team."
"It's an expensive solution but you get a very good product for the price. Compared to other products, SentinelOne is definitely cheaper and the Microsoft E5 package is probably more expensive. Not many companies are willing to purchase CrowdStrike Falcon in Turkey due to the cost, but the market is changing."
"The solution's pricing is great for us."
"There are three to four licensing models available to choose from for CrowdStrike Falcon. The price of CrowdStrike Falcon depends on the distributor and the reseller partner. The price we received was good."
"CrowdStrike Falcon is one of the more expensive endpoint solutions on the market."
