Featured Reviews

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

"Support is very good."
"The tool sends an automated mail to all the operators, which makes it easy to share the information and reporting.​"
"The solution has gone beyond signature-based monitoring and analysis and is AI-powered. It is good enough to cover the full range of cybersecurity services."
"The most valuable features of ArcSight ESM are ease of use and readily usable components."
"The most valuable features of ArcSight ESM are the dashboards, ease of management for anyone, and simple for teams to provide reports related to cyber security. There are a lot of good features that are provided."
"I would rate the ease of use for new users an eight out of ten, with ten being easy to use. It is a good tool."
"Some of the benefits of using this solution are rapid correlation and near-time response on alerts."
"It prevented my users from getting infected by ransomware. It can also pinpoint the story behind every virus or network attack to our environment."
"It's easy to manage. There's a web interface and a command line, depending on what the user is comfortable with. There's a large knowledge base available, and the support is timely."
"Fortinet FortiSIEM is easy to use."
"Real-time monitoring makes life quite easy for me."
"Our customer did not have security monitoring in the first place. With this solution, it provided security posture management and visibility about the security landscape and threats that they had."
"The most valuable features for us are the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation."
"Its automated response feature has benefited our customer communication. Analysts feel more confident in providing timely responses."
"The stability is very reliable. It offers very good performance."
"FortiSIEM is a great tool for making security processes transparent."
 

Cons

"They should try to include business logic vulnerabilities in the SIEM tool."
"When we need to consume old events, we have to wait for a long time. ArcSight should improve the database capability to reply to queries faster. It would also be interesting if they implemented network visibility. For example, they could add a feature like NetWitness with a model just for looking through the packets."
"Customer service and support is our biggest challenge."
"I would like for them to integrate mobile devices. Integration or any kind of functionality which will act as a substitute for IBM so that we can really track our mobile devices as well as look at SIEM."
"Deployment typology could be improved. Difficult to scale across all the different lines of businesses."
"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery."
"The centralized dashboard for the hybrid cloud environment needs to be more focused. It needs to be redefined because it's missing most of the information. It should be a little bit easy to use. Currently, integration with various applications and connectors is not that easy. Deployment is easy, but integration is not that easy. ArcSight also has a very high bandwidth consumption to pull the local servers. It should have some kind of better process or ability to transfer files from on-premises to the cloud, from the cloud to on-premises, and from a cloud to another cloud."
"The only concern is that AI needs to be integrated"
"I would like to see easier implementation in the future."
"We expect the latest patch from Fortinet FortiSIEM to give the ability to work with signature files."
"It would be good if the solution offered even more configuration options, especially in relation to the VPN so that it continues to be a very flexible option."
"Areas for improvement would be the ease of use and the integration with Fortinet's own products."
"There could be more AI features included in the product."
"It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there."
"The UI could improve in Fortinet FortiSIEM. Humans view the UI frequently for data and if it was more visually pleasing it would be beneficial."
"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
 

Pricing and Cost Advice

"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"The product licenses are inexpensive."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"Aggregation can help a lot in pushing down licensing costs."
"The licensing cost is affordable if you get an enterprise license. The licensing is based on EPS, so you can probably provide a package of license for multiple ESMs with their correlational end fees. It is cost-effective."
"The pricing is great compared to others."
"It's a good price, it's one of the cheaper solutions."
"There is a license required for this solution."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"There are additional features that cost more than the standard licensing fees."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"The price is competitive."
"The solution is available for both, perpetual and subscription licenses."
"Fortinet's products are not expensive, it is less than the competition."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
