Executive SummaryUpdated on Sep 18, 2024

Review summaries and opinions

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

ROI

Sentiment score
1.0
Fortinet FortiSIEM delivers security improvements and customer satisfaction, leading to positive financial outcomes despite no explicit ROI measurement.
Sentiment score
5.7
LogRhythm SIEM enhances detection, response times, productivity, and security posture, offering cost-effectiveness and resource savings for medium-sized organizations.
 

Customer Service

Sentiment score
7.4
Fortinet FortiSIEM's customer service is seen as professional but has mixed reviews on response times and support accessibility.
Sentiment score
5.4
LogRhythm SIEM's support excels in expertise and quick resolutions, earning high satisfaction despite occasional delays.
There is a knowledgeable, though small, team of support engineers around the world.
Local tech support is available, however, for more critical or technical issues, we depend on the OEM directly, especially when it comes to on-prem solutions.
They take some time to respond because they need logs and investigations, which delays the response time.
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
7.2
Fortinet FortiSIEM scales well, accommodating different business sizes but faces challenges with licensing, architecture, and configuration complexities.
Sentiment score
7.8
LogRhythm SIEM is highly scalable, easily expands across environments, and integrates well, suitable for medium to large enterprises.
Fortinet FortiSIEM is highly scalable.
At any point in time, when network devices increase or there is a change in the infrastructure, we can add more workers and collectors to expand our infrastructure setup.
Fortinet FortiSIEM is easy to scale.
LogRhythm SIEM is scalable; it can handle about 200 or 500 devices without much difference.
The scalability of LogRhythm SIEM is good enough, warranting an eight out of ten rating.
LogRhythm SIEM is highly scalable as it has modular components allowing me to expand storage, indexing, or other resources as needed.
 

Stability Issues

Sentiment score
5.6
Fortinet FortiSIEM is reliable and stable, handling updates well, with users rating its performance highly despite occasional bugs.
Sentiment score
4.7
LogRhythm SIEM is stable with high uptime, strong support, handling large data, though updates may affect stability.
It stabilizes itself in an appropriate time, so its uptime is good.
Some stability issues occur, but Fortinet's technical support team provides assistance.
These issues may cause unusual errors and user interface issues.
The platform needs regular updates to fix problems encountered with each quarterly patch and version release.
LogRhythm SIEM still needs improvement regarding stability, particularly in environments with heavy data consumption.
 

Room For Improvement

Fortinet FortiSIEM needs improvements in integration, user interface, support, cost, and features like AI and automated responses.
LogRhythm SIEM needs improved integration, user interface, automation, scalability, documentation, and compatibility with non-mainstream platforms and Linux.
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management.
Enhancing the completeness of its APIs could aid in better external integrations.
Recently, they revised it to a subscription-based, all-inclusive license.
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.
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.
A more user-friendly user interface with drag-and-drop features, similar to key competitors like Splunk, would be beneficial.
 

Setup Cost

Fortinet FortiSIEM provides flexible pricing that can be cost-effective, but costs may increase with additional modules and scalability.
LogRhythm SIEM is cost-effective for enterprises, offering transparent pricing and flexible licensing, yet incurs higher professional service fees.
Windows agent licenses cost around 3,000 Rupees per device per year.
Setting it up for oneself as an enterprise-licensed product can be quite expensive.
The revised model is subscription-based and more flexible.
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 FortiSIEM provides automation, analytics, and integration with a user-friendly interface for efficient threat detection and network monitoring.
LogRhythm SIEM offers advanced threat detection, user-friendly interface, comprehensive log management, and automated alerts for enhanced security efficiency.
It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security.
I find the real-time monitoring and correlation capabilities effective for security alerts.
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.
The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient.
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.

Systems monitoring enhanced by firewall and intrusion detection features
My primary use case for Fortinet FortiSIEM is systems monitoring and alerting. I use it for standard functions like log monitoring, incident detection, and notification.  My customers are mostly medium-sized enterprises ranging from engineering companies, mining companies, independent schools, and…
SumitKumar20 - PeerSpot reviewer
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.
