Interpreting data effectively despite challenges in integration and support
If someone lacks the budget for a new SIEM tool with advanced capabilities, I would recommend ArcSight Enterprise Security Manager (ESM). However, if they have the budget, I would suggest looking into other options. Overall, I would give ArcSight Enterprise Security Manager (ESM) a rating of seven out of ten.

Quotes from Members

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

Pros

"The feature that I have found the most useful is that it can be deployed to the cloud."
"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."
"Feature-rich solution which provides better network visibility for improved security"
"ArcSight ESM allows us to find if someone is doing an administrative operation at inappropriate times of day or trying to do something they're not allowed to."
"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."
"I really like the correlation part and the way the logs are correlated. I have never faced issues with parsing in this product. I like the way it parses, and everything is so clear to me."
"There are many features that are good for clients who are looking for a good SIEM solution. They like the ease of creating a business that is effective and impressive."
"We utilize ArcSight ESM for real-time threat detection in our organization. We have custom rules that we've developed on top of the WAN services, along with scheduled licensing activities."
"The algorithm used in Seceon OTM is clear and logical, categorizing events as needed. This helps us identify and respond to threats effectively."
"We only recently started using Seceon, so we aren't taking advantage of all its features yet. We have enabled some proactive alerts about utilization and bottlenecks from high traffic."
"You can use different solutions in a single platform which is very easy and attractive for customers."
"The pricing of Seceon Open Threat Management Platform is very reasonable."
"The solution is very cost-effective compared to Splunk and LogRhythm."
"It is effective because it has threat intelligence from across the world and constantly checks and updates for new threats."
"It offers a holistic approach with multiple solutions blended into one platform."
"Seceon Open Threat Management Platform notifies only genuine alerts. It offers plenty of options that are suitable for MSPs."
 

Cons

"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."
"The initial setup could be more straightforward."
"The way that scaling is set up isn't very cost-effective."
"They need to develop NetFlow appliances that can be installed in the customer network on span ports, collect NetFlow, and send it to ArcSight without relying on the devices' NetFlow capability and their position in the network."
"Micro Focus does not have a physical presence here in Pakistan, although IBM does."
"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."
"Currently lacks SOAR feature."
"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."
"For future releases, integrating incident response tools and improving communication on incident reporting could be beneficial."
"Certain features, such as DLP, need to be improved as they are superficial and not in-depth."
"It would be better if they offered global coverage."
"It is a standalone solution now. They need to make it into a cloud-based subscription model. It needs more compatibility for co-managed solutions. It can also have more threats and deeper integration with Microsoft."
"Seceon Open Threat Management Platform sells some add-ons as part of the whole suite but not individually. If they sold them individually, they could potentially attract more business."
"We are at the client’s end, offering services. They don’t know about security rules and benchmarks. We are working on the discovery and remediation but we don’t really have the intelligence that was available while working with other tools. Human working is also very essential for the solution. The automatic session is impossible to play since it needs to touch Redfin for further analysis. No one has breached our clients."
"The product could be improved by including sandboxing capabilities in the next release."
"It would be ideal with the processing was more manageable. Not many customers are willing to have a dedicated server with two CPUs and one TB of memory. The cost of this is huge for a smaller organization."
 

Pricing and Cost Advice

"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"​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.​"
"The solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
"We're paying a fee for an MSSP, and the cost of the total cost of ArcSight ESM was approximately three to four million dollars a year. The price was less than similar solutions. We did not have additional fees."
"The product licenses are inexpensive."
"The cost of the solution is not very high, although hiring a qualified analyst to work with the product is expensive."
"The pricing model is expensive compared to open-source alternatives."
"The price is quite reasonable."
"We used the solution's trial version for two months and later purchased it."
"Seceon Open Threat Management Platform is cost-effective because it's a comprehensive platform that offers high availability."
"I find Seceon OTM's pricing to be reasonable, not too high or low, just okay for the market standards. I can't disclose specific figures, we pay on a quarterly basis under a service model. I would rate it eight out of ten. As a customer, I always hope for better pricing options."
"It has a per-asset model instead of an ingestion-based model, which gives predictable pricing. In terms of price, it is in the middle to lower range of SIEMs that it competes against. It is the most affordable solution that we have implemented so far. It was much more affordable than anything else I've implemented."
"The pricing is very competitive. It's not expensive."
"The solution is cheap and very competitive. It offers good tuning in terms of the pricing. Other solutions like Palo Alto and IBM are more expensive."
