Network Security Engineer at Ensure Support Services Limited
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.

Head of Technology at Techfruits
It provides a reliable solution for managing network-wide data.
Technical Engineer - Technical Security at a tech services company with 1,001-5,000 employees

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

Room For Improvement

Users recommend enhancing FortiAnalyzer's interface, integration, support, and AI while addressing high costs and setup complexity.
LogRhythm SIEM needs improved integration, user interface, automation, scalability, documentation, and compatibility with non-mainstream platforms and Linux.
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 Analyst 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.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
Product Development - Security Solutions Manager at Aplikanusa Lintasarta
 

Setup Cost

Enterprise buyers find Fortinet FortiAnalyzer pricing varies, with competitive rates but high costs for extensive licensing and setups.
LogRhythm SIEM is cost-effective for enterprises, offering transparent pricing and flexible licensing, yet incurs higher professional service fees.
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 1,001-5,000 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.

Valuable Features

Fortinet FortiAnalyzer offers centralized analysis with real-time logs, customizable dashboards, and automation for effective network management.
LogRhythm SIEM offers advanced threat detection, user-friendly interface, comprehensive log management, and automated alerts for enhanced security 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 Analyst 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.

Simplifying log management by displaying detailed access information
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. This visualization and detail make managing logs more straightforward. In conjunction with our VMware setup, Fortinet FortiAnalyzer enhances organizational efficiency, meeting the standard log retention period for up to a year.

Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. 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.
