LogRhythm SIEM still needs improvement regarding stability, particularly in environments with heavy data consumption.
Security Engineer at Granicus Inc.
 

Room For Improvement

Fortinet FortiAnalyzer needs enhanced UX, report customization, third-party integration, competitive pricing, real-time monitoring, support, and predictive analytics.
LogRhythm SIEM needs improved integration, customization, performance, usability, better support, and enhanced documentation for optimal user experience.
When licensing, each device is licensed separately, such as the firewall, which can become expensive.
Network &Security Engineer at Natioanal Drug Authority Uganda
This would help in analyzing various security incidents and events more effectively by delivering a handful of relevant logs instead of thousands.
Product Manager at a comms service provider with 10,001+ employees
Enhanced deep inspection features would make troubleshooting easier.
Head of Technology at Techfruits
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.
Cyber Security Engineer at Diyar United Company
There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments.
Security Engineer at Granicus Inc.
If LogRhythm SIEM could make a lightweight version of their solution, that would be quite competitive because some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity.
Engineer Information Security at N-Able (Pvt) Ltd
 

Setup Cost

Fortinet FortiAnalyzer is cost-effective for mid to large organizations but can be expensive for smaller businesses.
LogRhythm SIEM offers competitive, transparent pricing suitable for medium to large businesses, with high initial setup 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.
Technical Engineer Technical Security at a tech services company with 10,001+ employees
In terms of pricing, FortiAnalyzer is not expensive.
Technology Consultant at 1ware
In the Indian market, Fortinet's pricing is very competitive, allowing us to win most of our deals.
Product Manager at a comms service provider with 10,001+ employees
The license cost is around $10 per MPS.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
I find LogRhythm SIEM affordable, as it is a bit less costly than QRadar.
Cyber Security Engineer at Diyar United Company
 

Valuable Features

Fortinet FortiAnalyzer provides centralized log management, customizable reporting, and integration with Fortinet devices for efficient network security management.
LogRhythm SIEM offers AI-powered features, seamless integration, and user-friendly dashboards for enhanced security and operational efficiency.
The advanced analytics capabilities aid in threat detection by providing visibility into indicators of compromise.
Information Security Engineer at a tech services company with 11-50 employees
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.
Head of Technology at Techfruits
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.
Senior Manager at ITX360 (Pvt) Ltd
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
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.
Cyber Security Engineer at Diyar United Company
This helps SOC analysts significantly as they can monitor all log sources through a dashboard, quickly identifying which sources haven't reported within their specified timeframes.
Security Engineer at Granicus Inc.

Amarnath Jaiswal - PeerSpot reviewer
Senior Manager at a manufacturing company with 501-1,000 employees
Comprehensive log analysis has improved traffic monitoring and streamlined risk mitigation
Fortinet FortiAnalyzer is a very comprehensive analyzer providing detailed analyzing features and customizable reports. I can get customization and custom reports, and there are many functions available. It is very good for any organization.Log management in Fortinet FortiAnalyzer is excellent, as it stores approximately two years of logs. Using Fortinet FortiAnalyzer, I analyze vulnerability risks and threats and sort out problems accordingly. I then create policies and mitigate the risk based on my findings. I have created many customizable reports in Fortinet FortiAnalyzer. I have customized the reports to schedule them and generate reports every day that are sent to my email. I am not using any SIEMs, but Fortinet FortiAnalyzer is the best and looks like a SIEM. I did not integrate Fortinet FortiAnalyzer with any security information and event management solutions. With Fortinet FortiAnalyzer, I have streamlined the process to mitigate risks and save time to get event information on any type of threats, risks, and unwanted traffic. Risk and time are saved, and it is valuable for any organization.
SumitKumar20 - PeerSpot reviewer
Security Engineer at Granicus Inc.
Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.
