ROI

Sentiment score
7.4
Fortinet FortiAnalyzer offers favorable ROI through competitive pricing, effective problem resolution, network visibility, and significant cost savings.
Sentiment score
8.0
LogRhythm SIEM boosts ROI, visibility, and security compliance, offering cost-effective risk management and productivity benefits, especially for medium enterprises.
The impact of the tool is low when the functionalities are inaccessible due to resource consumption.
Fortinet is highly efficient for moderate deployments and provides a secure platform for medium-sized networks and data centers.
I have seen a return on investment with Fortinet FortiAnalyzer due to its competitive pricing and straightforward licensing model based on the amount of log data processed per day.
 

Customer Service

Sentiment score
7.4
Fortinet FortiAnalyzer support is mixed, with varying satisfaction due to response times and regional differences in effectiveness.
Sentiment score
6.9
LogRhythm SIEM's support is knowledgeable and responsive, though consistency and initial response times need improvement.
Customer service and support for Fortinet FortiAnalyzer are quite helpful and responsive.
Technical support is good, and I rate it ten out of ten.
The support service is very slow and incompetent.
The technical support is good; we have a separate portal for partners, and since we are paying for the service, they provide a response timeframe based on severity—critical issues are addressed within four hours, medium issues within one day, and non-urgent issues may take a couple of days.
Customer support is very helpful and effectively solves my problems.
 

Scalability Issues

Sentiment score
7.3
Fortinet FortiAnalyzer is scalable and flexible, but sizing and cost can affect performance, especially with high log volumes.
Sentiment score
7.6
LogRhythm SIEM is praised for its strong scalability and effectiveness in accommodating expanding demands across diverse environments.
Fortinet FortiAnalyzer is scalable, especially for the VM versions, as additional space can be provisioned from the servers as needed.
FortiAnalyzer is a scalable product.
It typically handles three to five years of expansion effectively.
LogRhythm SIEM is highly scalable as it has modular components allowing me to expand storage, indexing, or other resources as needed.
LogRhythm SIEM is scalable; it can handle about 200 or 500 devices without much difference.
 

Stability Issues

Sentiment score
8.4
Fortinet FortiAnalyzer is praised for its stability and reliability, though some experience occasional performance issues with resource limits.
Sentiment score
4.4
LogRhythm SIEM is generally stable, reliable, and efficient, with some performance issues resolved through updates and proper resource allocation.
We faced some CPU consumption issues, which caused the machine to slow down and required a restart of FortiAnalyzer.
It remains stable during implementation for one or two years.
It provides a reliable solution for managing network-wide data.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
 

Room For Improvement

Users want Fortinet FortiAnalyzer to improve its interface, third-party integrations, cloud technology support, and cost efficiency.
LogRhythm SIEM needs better integration, UI improvements, enhanced reports, and Linux-based support for efficiency and tool integration.
When licensing, each device is licensed separately, such as the firewall, which can become expensive.
This would help in analyzing various security incidents and events more effectively by delivering a handful of relevant logs instead of thousands.
Enhanced deep inspection features would make troubleshooting easier.
I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
 

Setup Cost

Fortinet FortiAnalyzer pricing ranges from $11,000 to $50,000 annually, with calls for adjustments for smaller enterprises.
LogRhythm SIEM offers competitive pricing with comprehensive features, though scalability and additional features may increase costs.
Its licensing model is based on the amount of log data processed per day, making it more cost-effective compared to QRadar, which is EPS and device-based.
In terms of pricing, FortiAnalyzer is not expensive.
In the Indian market, Fortinet's pricing is very competitive, allowing us to win most of our deals.
The license cost is around $10 per MPS.
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.
 

Valuable Features

Fortinet FortiAnalyzer offers robust reporting, real-time monitoring, and advanced analytics for comprehensive network visibility and simplified security tasks.
LogRhythm SIEM excels in threat detection, user-friendly interface, and integration, offering centralized logs and customizable alerts.
The advanced analytics capabilities aid in threat detection by providing visibility into indicators of compromise.
The most valuable feature of Fortinet FortiAnalyzer is its ability to simplify and display logs clearly, providing details like which IPs are accessing the system, the destination, and the policies applied.
The log management is useful as we have connected around two hundred eighty-five walls and around fifteen to twenty plus firewalls with Fortinet FortiAnalyzer, making it highly beneficial compared to logging into each individual firewall.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
We have enough budget for cloud deployment, but we choose to keep it on-prem to ensure data privacy; cyberattacks are a concern, but data privacy is the foremost priority due to sensitive government information.
