Johnny Suleiman - PeerSpot reviewer
Scalability is a key feature as it allows easy scaling of the platform without downtime
OpenSearch is used as a search engine for specific logs, mainly in e-commerce and monitoring the logs themselves. It is very valuable for e-commerce, enabling data analysis on application logs and customer behavior, and can be integrated with other services, including AI and machine learning…

Quotes from Members

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

Pros

"This service already sorts data like vectors. They have classified the storage pre-defined."
"The initial set up is very easy...We really appreciate Amazon!"
"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."
"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."
"We retrieve historical data with just a click of a button to move it from cold to hot or warm because it's already stored in the backend storage"
"The business analytics capabilities are the most important feature it provides."
"Our customers have seen tangible benefits from Amazon OpenSearch Service, especially in terms of their applications running smoothly, so they do get a return on investment."
"It's a good log management platform. In terms of infrastructure management, it's good."
"The asset discovery and inventory capabilities in USM Anywhere is quite good."
"Any unusual behaviour, we can monitor. We have alerts set up to be sent when we receive signs of any unusual behaviour."
"The solution has all the features that we need, however they do not work correctly."
"Its powerful correlation engine helps reduce time in manually correlating events."
"What I find the most valuable about USM Anywhere is its compliance. It shows a list of all the administrators logged on and does it quite well. There are no whistles and bells, it's reliable and simple to use."
"AT&T AlienVault USM is good for ELK Stack, the user experience is great because of its architecture. The ELK has a great performance and it has very good speed in the search and Kibana. Additionally, the visuals and dashboards and very nice and customizable."
"The asset management functionality (active and passive scans) is also really important. You can't protect what you do not know about, so having an inventory of all your devices and software is critical to a security management program."
"Asset discovery and vulnerability scanner are good features. The integration between this solution and OTX, which is an AlienVault platform for Open Threat Exchange, is also a valuable feature. It is also quick and easy to deploy, so you can quickly engage with a customer's environment."
 

Cons

"The configuration should be more straightforward because we had to select a lot of things."
"One improvement I would like to see is support for auto-scaling."
"I would say that, basically, the configuration part is an area with a shortcoming...Some upgradation is required on the configuration side so that we can get to use it."
"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."
"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."
"Amazon Elasticsearch can improve the bullion in the near search and the ease of integration with Kibana. Additionally, there could be more flexibility in the configuration and documentation."
"They can enhance data visualization."
"One glaring issue was with our mapping configuration as the system accepted the data we posted, but after a few months, when we attempted complex queries, we realized the date formatting had become problematic."
"AlienVault must improve their correlation feature. Some of the events do not match with the correlation rules and some of the correlation events are false-positive."
"The AT&T AlienVault USM is okay, but the relational database is not very good for large amounts of data. For example, many logs cannot be processed. It has been very slow for the queries and some data which are large, it is not very good in this case."
"I've been told that AlienVault doesn't have a full version of NES running in there, but I'm not sure if that's accurate or if my engineer made it that way. I'm not sure he was completely honest either because we had NES in the environment before. Those tools could be improved because AlienVault is a SIEM, and it added all these other features."
"We've had some stability problems, not a lot, but a few. Updates seem to be the worst. That seems to be when the stability problems come up."
"The vulnerability reporting needs to have options to be able to sort or customize the output."
"I want to see more compliance management capability. The quality of integrations seems to be a little bit low."
"The reporting module could be a little easier to handle, as it requires quite some trial and error until you get the reports you want. Also, it would be great to have a graphical interface for the Network Intrusion Detection System's rule management."
"Adding a parsing interface for the customers would make AT&T AlienVault USM better."
 

Pricing and Cost Advice

"The solution is not expensive, but priced averagely, I will say."
"You only pay for what you use."
"Compared to other cloud platforms, it is manageable and not very expensive."
"There is a community edition available and the price of the commercial offering is reasonable."
"QRadar, ArcSight and Splunk are some of the most expensive SIEM products out there in the market and not everyone has the budget to buy them. In such cases, AV USM is a very cost effective alternative."
"​The vulnerability management solution is worse than buying a Nessus Professional license.​"
"We checked out several competitors. For what it can do and the cost, it was the best option!"
"It is affordable, and it also has many features that the premium products such as ArcSight and QRadar have. It is a very good platform for a SIEM solution. Everything is included in the price."
"Its price is in the medium to upper range."
"It's affordable for most customers."
"The ROI is quite good."
"AlienVault is certainly not nearly as expensive as Splunk or QRadar. It's decently priced, but I don't have the exact figure."
