An open-source solution that gave us insight into our clients' network traffic flow
We use the solution for packet capture sampling. We offer it as part of our managed service. It's so we can identify east-west traffic on a customer's network Corelight is low-cost and made on open-source, and the code is Zeek. It's an easy way for us to get visibility in a client's environment.…

Cyber Security Senior Technical Consultant at a consultancy with 11-50 employees
Built faster threat response and improved visibility with real-time monitoring and flexible deployment
TrendAI Vision One allows us to monitor attacks in real time, which is a significant benefit. We can quickly see where the attack is coming from. TrendAI Vision One enables us to use different products with a flexible license. For example, if a customer is using endpoint security and wants to switch to another solution, they can instantly use a different Trend Micro product, such as email. TrendAI Vision One has helped to reduce the time to detect and respond to different threats, as it can respond to attacks very quickly. With playbook templates, in cases of recurring attacks, responses can be made quickly using predefined playbooks. TrendAI Vision One has helped to reduce noise from false positives. There have been false positives before, but it was due to the customer not telling us which app they were using. Best practice configurations must be applied properly to avoid such issues. TrendAI Vision One helps customers consolidate the use of security vendors and reduce silos by offering one platform for all product management.

Quotes from Members

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

Pros

"Corelight makes much easier the remediation of cyber attacks; instead of facing a chaotic amount of logs, Corelight provides correlated metrics that allow pivoting to find, in seconds, all the data related to an alert, detection, or asset."
"It's easy to create additional dashboards specific to supporting specific tasks."
"The most valuable feature is the embedded IDS from Suricata."
"It is easy to deploy and easy to handle."
"It is easy to deploy and easy to handle."
"Corelight is easy to use."
"It's an easy way for us to get visibility in a client's environment."
"Technical support seems to be good."
"I appreciate the value of real-time activity monitoring."
"The versatility of TrendAI Vision One is what I like the most; we have a lot of options."
"This full security posture positions us well for our future security roadmap."
"XDR provided a much more deep view into what is actually happening."
"TrendAI Vision One is very effective and very market competitive, which is why we are using it."
"The Trend hunting feature is beneficial, providing the opportunity to investigate and see what's happening, using frameworks such as MITRE ATT&CK to analyze logs."
"It is a stable product. It works very well."
"When we purchased Vision One, what set it apart was that it wasn't a traditional signature-based antivirus. It's a process-aware solution that provides real-time protection. That was a big differentiator three years ago, but now it's a given that every AV provider should be doing that. It combines signature-based telemetry with behavioral awareness and a detection-based solution, making it a good solution for us."
 

Cons

"In the next release, building a graphical user interface would be helpful."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Machine learning could be a good improvement, but it's very costly."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"Machine learning could be a good improvement, but it's very costly."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"Corelight hasn’t added features in a long time."
"It's an expensive solution and the price could be reduced."
"In terms of improving Trend Vision One, it might sound silly, yet it seems notoriously uncooperative with middle clicks and opening sections in new tabs. I'm a big tab browser, and it feels hitting a brick wall when I have to refresh in a new tab or make a copy of a tab to move forward."
"A room for improvement is Trend Micro XDR's website. It's a very complicated website since finding the right point one wants to see is difficult."
"The only downside to Trend Vision One is its complexity."
"While the continuous addition of features is commendable, the sheer volume of changes makes it difficult to stay abreast of the latest developments."
"TrendAI Vision One is expensive."
"Vision One's functional capabilities are excellent, but the platform can be upgraded and simplified in many ways. We use multiple playbooks to automate many things, but I'm not sure there are mature cybersecurity applications. There are several external alerts, and their behavior changes daily, so I'm not sure automation can help you that much. We're using the playbooks, but it might require some improvement."
"Our developers were understandably frustrated that they couldn’t debug code for a month and a half, which impacted our project timelines."
"We'd like to see more use of AI around analytics and controls."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"The pricing is competitive, and the cost aligns with the features we receive."
"The pricing is fair and not on the higher side."
"Trend Micro solutions are very expensive compared to other solutions. Even though everything is in one console, each feature requires a separate license."
"Trend Vision One offers a competitive price-to-value ratio."
"It's relatively well-priced."
"When we have a good product such as Trend Vision One, the price is fine."
"It is costly. It is not that affordable for a small organization. Only big organizations can afford it. It is a new feature that has been added, so its price is fair. Its licensing is probably subscription-based. It is for one or two years."
"The price for Trend Vision One is reasonable compared to Microsoft and Symantec."
