The support quality could be improved.
Resolving issues promptly.
They are responsive and provide high-quality assistance.
 

Scalability Issues

Sentiment score
6.9
Fortinet FortiGate scales well when correctly sized, though design flaws and licensing issues can cause problems.
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
7.4
Palo Alto Networks VM-Series offers high scalability and adaptability, with some configuration challenges but generally positive user experiences.
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.
They are easy to upgrade, and with credit licensing, they scale effectively according to demand.
The solution is scalable and can easily handle an increase in the number of users.
It is easy to use with an excellent graphical user interface and extensive documentation, which contributes to its high scalability.
 

Stability Issues

Sentiment score
7.4
Fortinet FortiGate is praised for stability and reliability, with minor bugs, quickly addressed by regular firmware updates.
Sentiment score
7.2
KerioControl is stable and reliable, with minor hardware or update challenges, and performs well according to user assessments.
Sentiment score
8.1
Palo Alto Networks VM-Series is highly stable, with minor issues during updates, making it a robust choice for users.
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.
Hardware is generally very stable.
I have not experienced any major problems or downtime.
Perfection is unlikely as the dynamic nature of traffic and constant changes can result in occasional bugs despite regular updates.
 

Room For Improvement

Fortinet FortiGate needs simplified interface, expanded features, better stability, improved support, and competitive pricing for enhanced user experience.
KerioControl requires improvements in VPN, user interface, support, security, performance, and customization features for large networks.
Palo Alto Networks VM-Series needs UI, reporting, integration, cloud compatibility, scalable features, clear pricing, and enhanced AI capabilities.
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.
Integration with CSIRT across all use levels would make it easier for administrators to stay updated on the blocked entities without manual intervention.
Most customers go for partner-enabled support, which involves multiple layers, leading to delays.
When managing the firewall, it involves a Strata Cloud web browser that requires improvement to enhance deployment ease and call center efficiency.
 

Setup Cost

Fortinet FortiGate offers competitive pricing with clear licensing, value bundles, and cost-effective performance features for enterprise buyers.
KerioControl offers affordable pricing with complex licensing, appreciated features, but high annual fees can be challenging for small offices.
Palo Alto Networks VM-Series offers robust security and flexible pricing but requires careful licensing for cost-effectiveness.
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.
Palo Alto is expensive in terms of pricing, particularly when comparing features to cost.
The cost involves purchasing through a vendor, which might mark up due to the supply chain.
Pricing for Palo Alto Networks is higher than other OEMs, but considering the robustness and features, it gains customer trust.
 

Valuable Features

Fortinet FortiGate is favored for its security, VPN, ease of use, SD-WAN, advanced protection, and affordability.
KerioControl provides user-friendly navigation, robust security features, VPN support, and efficient network management with positive feedback on ease of use.
Palo Alto Networks VM-Series offers advanced threat management, scalability, and security for cloud and data center environments with intuitive 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.
We use these tools to prevent all known and unknown threats using Palo Alto Networks' Wildfire and other data filtering tools to gather information, analyze traffic, manage malicious traffic, and offer visibility, control, and attack prevention.
Palo Alto's robust threat intelligence supports new updates, and I can open cases directly with their Threat Intelligence team.
The DNS security significantly enhances security through visibility and detection, allowing control over crucial traffic like DNS, which is often exploited by ransomware.

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.
