7.5
Cisco Secure Firewall support is highly rated for knowledgeable assistance, though response times and access vary based on contracts.
Sentiment score
7.8
Fortinet FortiOS support is helpful but inconsistent, with quick basic solutions, delays on complex issues, and documentation needing improvement.
Sentiment score
8.0
Meraki MX customer service is praised for efficiency, 24/7 availability, quick resolutions, and knowledgeable staff, with overall satisfaction.
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 to provide many logs, yet problems remain unresolved, often requiring workarounds rather than solutions.
I have been working with them on firewalls, wireless, switching, and routing, and the support is the best.
They have expertise and provide solutions for the most difficult problems.
I would rate them nine or ten out of ten.
Fortinet technical support is very responsive and helpful.
Support engineers sometimes lack eagerness to assist with issues such as the memory problem.
When we raise a ticket with Meraki MX, they instantly become available to support us for configurations or troubleshooting.
 

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
7.2
Cisco Secure Firewall offers scalability and integration, though licensing complexity and scalability challenges in growth may concern some users.
Sentiment score
8.6
Fortinet FortiOS offers scalable solutions for varying business sizes, though some hardware upgrades may be needed for expansion.
Sentiment score
7.5
Meraki MX is scalable for SMBs, but major enterprises may require upgrades; it integrates well within Meraki products.
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.
Scalability presents a challenge.
Compared to FortiGate and Palo Alto, it lags in configuration and other aspects.
Even with the highest one, the 4600, we still face issues, particularly when transitioning between screens; it becomes very slow.
When customers' networks grow and needs expand, we can easily switch between models to trade up devices.
It allows for the expansion of users and devices without additional licensing costs.
Fortinet FortiOS is scalable, allowing the addition of users and firewalls as required.
When you have hundreds of thousands of people it is very difficult to scale in Meraki.
We have Juniper solutions, and I would say the Juniper solutions can scale better, however, this solution is still very scalable.
 

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
Cisco Secure Firewall is highly reliable with minimal outages, though occasional upgrade issues are typically fixed with updates.
Sentiment score
7.5
Fortinet FortiOS is stable and reliable, outperforming alternatives, with any issues mainly due to configuration challenges.
Sentiment score
8.4
Meraki MX is stable with minor issues, quickly resolved; redundancy features enhance reliability in configured environments.
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.
We have often encountered split-brain scenarios during failover processes and code upgrades, which have been persistent problems for us.
We work with a cluster with high availability, so if something goes wrong, we have it functioning.
Cisco Secure Firewall offers exceptional performance and stability.
While the product is largely stable, it sometimes faces memory issues in specific versions like 11 OE, which can be disruptive.
Stability is a seven out of ten because during version migrations, and sometimes with new versions, Fortinet is not as good.
I would rate the stability of FortiOS as an eight out of ten.
 

Room For Improvement

Fortinet FortiGate struggles with integration, user complexity, support inefficiencies, high costs, and feature performance, needing improved documentation and security.
Cisco Secure Firewall faces criticism for its complex GUI, high costs, and demands better features, integration, and performance improvements.
Fortinet FortiOS users want improved usability, better management, enhanced security features, and more efficient support, especially for 60D models.
Meraki MX needs better load balancing, integration, VPN capabilities, pricing, scalability, and advanced features for improved competitiveness.
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.
My ongoing complaint for the last six years has been the lack of CLI functionality, which hinders my ability to work on the firewall, alongside concerns regarding deployment time.
Firepower Management Center is quite out of date compared to other vendors.
The integration between Cisco products themselves presents difficulties, such as SD-WAN configuration.
Fortinet FortiOS faces memory issues, which can lead to unexpected downtimes.
There should be more documentation on how to use the CLI or how to perform CLI versions of tasks that can be done through the GUI.
Compared to other market leaders like Palo Alto and Check Point, FortiOS has many bugs in its initial releases.
It should automatically remediate and find out the issue and then resolve it on its own without interrupting the work of the employees.
Data is the only path, so optimization is essential.
 

Setup Cost

Fortinet FortiGate offers competitive, cost-effective pricing, appealing to small-medium businesses with flexible licensing and valued security solutions.
Cisco Secure Firewall is costly but offers robust support and reliability; licensing complexity can be mitigated by smart licensing.
Fortinet FortiOS pricing is moderate and scalable, with renewal costs potentially high despite competitive initial bundling offers.
Meraki MX offers cloud management value; despite high costs, ease of setup and low management justify competitive ownership expenses.
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.
It's good to have them, however, it costs us a lot.
It's considered a premium, but people pay that price for Cisco.
There are a lot of in-place contracts for us that provide the benefit of discounts.
It is an affordable solution for us.
Fortinet products are somewhat pricey, similar to Cisco equivalents, however, they have justified their price point.
I am satisfied with the pricing, licensing, and setup costs of FortiOS, rating it nine out of ten compared to other familiar leading firewalls.
I get it for $25,000, a device that can connect up to 75-100 users, whereas in Meraki MX, it goes to 75,000-80,000 per access point.
In terms of pricing, I would say it is not the cheapest, but it was comparable to the others.
It is neither expensive nor cheap.

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.
Phil Shiflett - PeerSpot reviewer
Unified policies streamline network management but complex licensing requires attention
Cisco Secure Firewall has some growth opportunities in terms of visibility and control capabilities regarding managing encrypted traffic. It has the ability to analyze encrypted traffic, and there is potential for more integration with APIs and AI to enhance these capabilities. Cisco Secure Firewall needs improvement in deployment time and the capability to access the CLI during support calls. I often encounter issues when technical support uses a CLI that is not familiar to me while troubleshooting through the GUI. My ongoing complaint for the last six years has been the lack of CLI functionality, which hinders my ability to work on the firewall, alongside concerns regarding deployment time. For the next release, they should look at the features offered by competitors such as Fortinet, including the ability to perform packet capture directly from the interface. If they enhanced their troubleshooting efficiency related to packet capture for each specific rule, it would simplify the process significantly.
Harshama Silva - PeerSpot reviewer
We have improved network security with user-friendly controls and high threat intelligence
FortiOS is very user-friendly and easy to configure for L1, L2, and L3 personnel. Its web filtering, application control, and IPS features are very user-friendly, easy to manage, and deploy. The threat intelligence in FortiOS is very high, and the system is scalable without additional licensing costs. FortiOS allows us to expand the number of users and devices as our network needs grow.
MURALI NIDAMANURI - PeerSpot reviewer
Experience improved network management with flexible and secure connections
I recommend that Meraki MX should improve to be a better solution for the next release by being more competent so that we can offer it as a primary solution among all other brands, although I don't have any specific feedback, while the competitors are also ahead of these solutions. Enhancing user experience is always required. Enhancing the seamless connectivity is crucial and user experience enhancement is needed daily, otherwise people find it outdated. New features should look and be dynamically connected, and users should not be bothered frequently when connectivity issues occur. It should automatically remediate and find out the issue and then resolve it on its own without interrupting the work of the employees.
