Customer Service

Sentiment score
6.4
Fortinet FortiGate's customer support is generally positive but varies in responsiveness and expertise, influenced by region and support tier.
Sentiment score
5.3
KerioControl support receives mixed reviews, with some praise but many report slow responses and reliance on online communities.
Sentiment score
7.2
WatchGuard Firebox support is praised for quick, knowledgeable service, though some delays occur in different time zones.
They offer very accurate solutions.
The quick resolution of issues with Fortinet FortiGate is due to the support of the company and the fact that the equipment is easy to work with.
I would rate the technical support for Fortinet FortiGate a ten out of ten.
I have never needed to contact customer support as the product is easy to use.
On a scale of one to 10, I would rate the technical support of the WatchGuard Firebox a 10.
The technical support is good.
 

Scalability Issues

Sentiment score
6.9
Fortinet FortiGate effectively supports scalable deployments, offering adaptability despite potential hardware limits and integration and licensing concerns.
Sentiment score
6.7
KerioControl suits small to medium businesses but faces scalability issues in larger enterprises, requiring hardware upgrades for increased capacity.
Sentiment score
8.1
WatchGuard Firebox is scalable for various needs, with upgrading options, though choices affect its scalability and performance.
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.
KerioControl has met some of the network infrastructure needs yet could improve in terms of scalability.
If we're going for more concurrent users, we need to change the entire box.
I find the WatchGuard Firebox scalable, as it's easy to change configurations from this product to another one.
 

Stability Issues

Sentiment score
7.4
FortiGate is praised for stability and performance, with minor challenges managed by updates, proper sizing, and support.
Sentiment score
7.2
KerioControl is stable and reliable, with minor hardware or update challenges, and performs well according to user assessments.
Sentiment score
8.6
WatchGuard Firebox is highly stable and reliable, with few issues, frequent updates, and high user satisfaction ratings.
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.
 

Room For Improvement

Fortinet FortiGate struggles with integration, user complexity, support inefficiencies, high costs, and feature performance, needing improved documentation and security.
KerioControl requires improvements in VPN, user interface, support, security, performance, and customization features for large networks.
WatchGuard Firebox needs a modern interface, better integration, enhanced features, and competitive pricing to improve user experience and marketability.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
The constant daily revisions necessitate meticulous identification of the relevant documents to prevent the use of outdated information that could jeopardize our environment.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
The cost for renewal after three years is 75% of the hardware cost, which is a significant problem.
When implementing a rule using a group of IPs, it is not possible to do that directly.
The WatchGuard Firebox has certain features, but the challenge is that we have some clients who don't have a network or are only mobile users, which leads us to think the future is in SASE products, not in the WatchGuard Firebox.
 

Setup Cost

Fortinet FortiGate offers competitive, cost-effective pricing, appealing to small-medium businesses with flexible licensing and valued security solutions.
KerioControl offers affordable pricing with complex licensing, appreciated features, but high annual fees can be challenging for small offices.
WatchGuard Firebox offers cost-effective pricing, especially for multi-year plans, with discounts and value for budget-conscious enterprises.
FortiGate is priced lower than Palo Alto.
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 is about 20% cheaper.
The price for the product is rated as ten out of ten.
When we tried to renew the Palo Alto license, the cost was beyond any reasonable range.
It's expensive us here.
I have faced challenges with the WatchGuard Firebox regarding price since we work with customers who use the Stormshield product, which is less expensive and French-made.
 

Valuable Features

Fortinet FortiGate is user-friendly, cost-effective, and offers high-performance comprehensive security with advanced threat protection features.
KerioControl provides user-friendly navigation, robust security features, VPN support, and efficient network management with positive feedback on ease of use.
WatchGuard Firebox offers user-friendly setup, robust security, excellent tech support, and scalable performance with comprehensive management features.
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.
The most valuable features include geo-tagging, which blocks all other IPs except for the specified accounts, and web filtering.
The Firebox offers valuable features such as network security, URL filtering, UTM features, intrusion prevention and detection, and authentication.
Basically, we have received a good return on investment.
I utilize AI within the WatchGuard Firebox, as we use the interconnection with threat syncs, and AI is implemented.

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.

Efficient bandwidth management and secure network access with a strong firewall
