7.0

Sentiment score
7.2
Splunk User Behavior Analytics is scalable and adaptable across environments, though storage limitations may affect scalability.
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
Splunk User Behavior Analytics is highly scalable, designed for enterprise scalability, allowing expansion of data ingestion, indexing, and search capabilities as log volumes grow.
 

Stability Issues

Sentiment score
7.5
Fortinet FortiGate is highly stable and reliable, excelling in continuous operation with effective network management, despite occasional update issues.
Sentiment score
7.8
Splunk User Behavior Analytics offers reliable performance and stability, with 99.9% uptime and ease of configuration in enterprises.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
Currently, we are experiencing a general outage of one of the main internet service providers of the Dominican Republic, and we have not been impacted in our operations because with SD-WAN, we have another internet service provider and we are working with the second WAN connection without any disruption.
With built-in redundancy across zones and regions, 99.9% uptime is achievable.
Splunk User Behavior Analytics is a one hundred percent stable solution.
Splunk User Behavior Analytics is highly stable and reliable, even in large-scale enterprise environments with high log injection rates.
 

Room For Improvement

Users express concern over Fortinet FortiGate's interface stability, functionality, performance issues, and call for improved support and features.
Splunk User Behavior Analytics needs better pricing, integration, user-friendly interfaces, enhanced features, and improved scalability and infrastructure.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
Global reach allows deployment of apps and services closer to users worldwide, but data sovereignty concerns exist and region selection must align with compliance requirements.
I encountered several issues while trying to create solutions for this advanced version, which seem unrelated to query or data issues.
High data ingestion costs can be an issue, especially for large enterprises, as Splunk charges based on the amount of data processed.
 

Setup Cost

Fortinet FortiGate offers high initial costs but competitive pricing, valued features, and flexible licensing compared to competitors.
Enterprise buyers find Splunk's User Behavior Analytics costly, with variable pricing based on data, hardware, and additional applications.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
It offers cost savings as it is generally cheaper than the competition.
It is about 20% cheaper.
Reserved instances with one or three-year commitments offer lower rates, providing up to 70% savings.
Comparing with the competitors, it's a bit expensive.
The pricing is based on the amount of data processed, and it is considered a high-level investment for enterprises.
 

Valuable Features

Fortinet FortiGate offers robust, affordable security with user-friendly interface, centralized management, and efficient SD-WAN capabilities.
Splunk User Behavior Analytics provides scalable, user-friendly threat detection with advanced analytics, machine learning, and seamless data integration and reporting.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
FortiGate has helped reduce the risk of cyberattacks that might disrupt our client's production.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.
I also utilize it for anomaly detection and behavior analysis, particularly using Splunk's machine learning environment.
Features like alerts and auto report generation are valuable.
Splunk User Behavior Analytics offers several beneficial features, such as Insider Threat Detection, account compromise detection, risk scoring, threat detection, and machine anomaly detection.

Featured Reviews

Vasu Gala - PeerSpot reviewer
A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Automatic reports streamline tasks and offers easy report gathering
The dashboard part could be improved. While using it, I noticed two options: Classic, which is adequate yet only in black and white, and another one that is more advanced or smart, though I forgot the exact term. I encountered several issues while trying to create solutions for this advanced version, which seem unrelated to query or data issues.

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
