Featured Reviews

Michael Wenn - PeerSpot reviewer
Has cloud-first architecture with SIEM technology to run security operations
When it comes to scale, they're architected quite well. They handle some of the biggest customers globally, with significant throughput on their platform, managing thousands of customers. One of the most impressive aspects of Devo is its customer community. A large majority, over 80 percent of their customers, actively participate on a Devo-specific community page. They're contributing to product development and support, events, and user group information, helping each other out. This high level of engagement is rare and demonstrates both the loyalty of their customer base and the quality of their product. They offer a range of small, medium, and large options to cater to everyone. I sold Devo products while working with them, focusing on enterprise solutions. However, as a small reseller, my customers were typically smaller businesses. I rate the solution's scalability a nine out of ten.
Ramnesh  Dubey - PeerSpot reviewer
Allows for monitoring logs according to industry standards within ESM but has a total capacity capped at 12 TB, limiting real-time data retention periods
The first limitation is with the ArcSight Data Storage Manager (ADSM). ArcSight's total capacity is currently capped at 12 TB. This becomes an issue if a customer needs a longer real-time data retention period, such as exceeding 90 days or reaching a year or even ten months. Increasing the disk space beyond 12 TB is not currently possible. So, increasing the storage capacity is one area for improvement. Additionally, the real-time data retention is limited due to the 12 TB restriction. Depending on the Events Per Second (EPS) you receive, you might only be able to retain data for seven to ten days. Overall, the 12 TB limit is the main issue we face in terms of maximizing real-time data storage. Moreover, there are a few improvements I would like to see in future releases. My main suggestion for ArcSight is to simplify the deployment process. Currently, the installation process is quite complex. There are various components involved, including transformations, multiple installations, and containerization for various components. Ideally, I'd recommend that ArcSight allow the entire installation, including the ESM and database, to be completed within a single unified setup process for a streamlined experience. Additionally, having readily available and well-organized documentation for the step-by-step installation process would be incredibly helpful. I would also like to see better support.

Quotes from Members

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

Pros

"It's very, very versatile."
"In traditional BI solutions, you need to wait a lot of time to have the ability to create visualizations with the data and to do searches. With this kind of platform, you have that information in real-time."
"One of the biggest features of the UI is that you see the actual code of what you're doing in the graphical user interface, in a little window on the side. Whatever you're doing, you see the code, what's happening. And you can really quickly switch between using the GUI and using the code. That's really useful."
"The most valuable feature is that it has native MSSP capabilities and maintains perfect data separation. It does all of that in a very easy-to-manage cloud-based solution."
"Devo has a really good website for creating custom configurations."
"The querying and the log-retention capabilities are pretty powerful. Those provide some of the biggest value-add for us."
"The alerting is much better than I anticipated. We don't get as many alerts as I thought we would, but that nobody's fault, it's just the way it is."
"Being able to build and modify dashboards on the fly with Activeboards streamlines my analyst time because my analysts aren't doing it across spreadsheets or five different tools to try to build a timeline out themselves. They can just ingest it all, build a timeline out across all the logging, and all the different information sources in one dashboard. So, it's a huge time saver. It also has the accuracy of being able to look at all those data sources in one view. The log analysis, which would take 40 hours, we can probably get through it in about five to eight hours using Devo."
"The reports that we are from getting from ArcSight are very valuable. The reporting in ArcSight is good. Our regulators ask us for the reports on a regular basis, and we have been able to provide the required data. Its overall functionality in terms of log analysis and the speed at which it does that is also valuable. It is very quick. Whatever alerts we had configured were extremely fast. We immediately get alerts when there is unauthorized access or unknown access, or even positive access. This is where we found the difference between ArcSight and other solutions."
"The most important feature is ArcSight's event correlation capabilities. It's powerful and easy. I also like the flex connector capability. It's easy to develop a new connector that isn't fully supported out of the box. For example, say you created a solution internally that's completely different, and it's not unsupported by the solution. You can write your own connector using the flex connector."
"This process has helped to improve our organization because we have centralized the intra-group security equipment logs."
"SmartConnector: Normalization parses raw logs and converts them into CEF (common event format). This is the core of the product."
"It is a very useful tool for intelligence building because it has many use cases and many rule sets."
"ESM has valuable features for event prediction and security analysis."
"It makes maintenance very easy."
"The correlation feature is good."
 

Cons

"Some third-parties don't have specific API connectors built, so we had to work with Devo to get the logs and parse the data using custom parsers, rather than an out-of-the-box solution."
"Their documentation could be better. They are growing quickly and need to have someone focused on tech writing to ensure that all the different updates, how to use them, and all the new features and functionality are properly documented."
"There's always room to reduce the learning curve over how to deal with events and machine data. They could make the machine data simpler."
"Some of the documentation could be improved a little bit. A lot of times it doesn't go as deep into some of the critical issues you might run into. They've been really good to shore us up with support, but some of the documentation could be a little bit better."
"An admin who is trying to audit user activity usually cannot go beyond a day in the UI. I would like to have access to pages and pages of that data, going back as far as the storage we have, so I could look at every command or search or deletion or anything that a user has run. As an admin, that would really help. Going back just a day in the UI is not going to help, and that means I have to find a different way to do that."
"The price is one problem with Devo."
"My opinion on the solution's technical support is not as great as it could be because of the issues I have faced regarding the service management element."
"From our experience, the Devo agent needs some work. They built it on top of OS Query's open-source framework. It seems like it wasn't tuned properly to handle a large volume of Windows event logs. In our experience, there would definitely be some room for improvement. A lot of SIEMs on the market have their own agent infrastructure. I think Devo's working towards that, but I think that it needs some improvement as far as keeping up with high-volume environments."
"ArcSight ESM could improve the alerts for the storage capacities or actions."
"It would be nice to have it on the cloud so that you can deploy it easily, saving time and resources."
"They should try to include business logic vulnerabilities in the SIEM tool."
"Deployment typology could be improved. Difficult to scale across all the different lines of businesses."
"I would like to have a feature that gives us an entire report listing what devices are integrated."
"It would be nice if the interface were more user-friendly, with, for example, a minimal number of tabs to navigate."
"It is quite complex and could use a better UI. So the improvement would be a simplification. It is pretty complicated to use. The architecture is not complex but the setup and use are."
"ArcSight is incredibly complex when configuring and deploying, and if your organization doesn't know what they want and what they need, ArcSight will be a challenge for them."
 

Pricing and Cost Advice

"Be cautious of metadata inclusion for log types in pricing, as there are some "gotchas" with that."
"Our licensing fees are billed annually and per terabyte."
"It's a per gigabyte cost for ingestion of data. For every gigabyte that you ingest, it's whatever you negotiated your price for. Compared to other contracts that we've had for cloud providers, it's significantly less."
"Pricing is based on the number of gigabytes of ingestion by volume, and it's on a 30-day average. If you go over one day, that's not a big deal as long as the average is what you expected it to be."
"I rate the pricing a four on a scale of one to ten, where one is cheap, and ten is expensive."
"It's very competitive. That was also a primary draw for us. Some of the licensing models with solutions like Splunk and Sentinel were attractive upfront, but there were so many micro-charges and services we would've had to add on to make them what we wanted. We had to include things like SOAR and extended capabilities, whereas all those capabilities are completely included with the Devo platform. I haven't seen any additional fee."
"Devo is definitely cheaper than Splunk. There's no doubt about that. The value from Devo is good. It's definitely more valuable to me than QRadar or LogRhythm or any of the old, traditional SIEMs."
"I like the pricing very much. They keep it simple. It is a single price based on data ingested, and they do it on an average. If you get a spike of data that flows in, they will not stick it to you or charge you for that. They are very fair about that."
"There is a license required for this solution."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
"Price-wise, ArcSight ESM was a bit high compared to competitors, which factored into our decision to switch to Splunk. It couldn't cover all our business needs for what we wanted to implement."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"Aggregation can help a lot in pushing down licensing costs."
"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"​It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders.​"
"Pricing is good, I'd rate the pricing a seven out of ten, with ten being low price. It's better than Splunk and IBM QRadar because their pricing is based on EPS."
