7.5
Fortinet FortiGate is valued for affordability, cost savings, enhanced security, operational efficiency, quick implementation, and long-term ROI benefits.
Sentiment score
7.2
Cisco Secure Firewall offers improved security and efficiency, but cost and ROI vary based on deployment and usage.
Sentiment score
7.4

Clients are now comfortable and not wasting productive hours on IT support.
The automation part is giving us a cost benefit and speed; we can react faster.
It's a very useful tool to mitigate and protect your enterprise.
The biggest return on investment when using Cisco Secure Firewall is that there's no waste in any infrastructure cost and licensing costs for us.
From my point of view, the biggest return on investment when using Cisco Secure Firewall is the single pane of glass, which is a huge plus for us.
The biggest return on investment for me when using Cisco Secure Firewall is reliability and robust network design.
That is a reason to buy a firewall, and it is challenging to put a monetary value on security.
 

Customer Service

Sentiment score
7.0
Fortinet FortiGate's customer service varies, with praise for responsiveness but criticism for slow, sometimes inadequate technical support.
Sentiment score
7.5
Cisco Secure Firewall support is highly rated for knowledgeable assistance, though response times and access vary based on contracts.
Sentiment score
5.4
SonicWall TZ customer service varies; some praise efficiency and competence, while others note slow response and communication issues.
I would rate their support for FortiGate a nine out of ten.
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 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.
Customer service is excellent.
 

Scalability Issues

Sentiment score
7.3
Fortinet FortiGate scales well for diverse enterprises, though planning and licensing are crucial to avoid hardware limitations.
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
SonicWall TZ offers suitable scalability for small to medium businesses, but model selection is crucial for future growth planning.
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.
 

Stability Issues

Sentiment score
7.9
Fortinet FortiGate is generally stable and reliable, with minor issues arising from new features, firmware updates, or hardware constraints.
Sentiment score
7.2
Cisco Secure Firewall is highly reliable with minimal outages, though occasional upgrade issues are typically fixed with updates.
Sentiment score
7.6
SonicWall TZ is highly reliable and stable, though minor issues occur under heavy use or after updates.
We're experiencing 99.999% availability consistently.
I would rate the stability of Fortinet FortiGate a ten out of ten.
We have not had any problems with the operating systems or maintenance of subscriptions.
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.
In terms of stability, SonicWall doesn't have performance issues.
SonicWall TZ is definitely stable and offers a good value for money.
 

Room For Improvement

Fortinet FortiGate needs enhancements in firmware, usability, integration, support, reporting, VPN, cloud integration, and documentation for seamless use.
Cisco Secure Firewall faces criticism for its complex GUI, high costs, and demands better features, integration, and performance improvements.
SonicWall TZ needs an improved interface, reporting, security features, and more efficient support, licensing, and advanced options.
By providing an integrated solution, users would have access to all features and functionalities within a single window, eliminating the need to navigate through multiple windows.
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.
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.
Integration with other vendors, especially with VPNs, can be challenging and requires more effort when configuring.
SonicWall TZ could benefit from newer technology.
The VPN license should be improved by providing more free SSL VPN licenses.
 

Setup Cost

Fortinet FortiGate offers competitive pricing with upfront affordability, simple licensing, and long-term value, despite potentially high renewal costs.
Cisco Secure Firewall is costly but offers robust support and reliability; licensing complexity can be mitigated by smart licensing.
Buyers find SonicWall TZ pricing competitive but potentially high due to additional subscription and licensing fees, affecting affordability.
The most expensive part is the renewal of the license subscription.
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'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.
More licenses are required to purchase the perpetual license for SSL VPN and Global VPN.
When comparing similar products across vendors, there may be a small difference in cost.
I would also position its pricing as a three, where one is the lowest price and ten is the highest.
 

Valuable Features

Fortinet FortiGate delivers robust security features and intuitive management, offering scalable and affordable network protection solutions.
Cisco Secure Firewall provides robust security, scalability, and central management, with intuitive tools for efficient threat protection and network monitoring.
SonicWall TZ offers user-friendly management, robust security features, and scalability, making it ideal for small to medium enterprises.
The firewall, IPS, and VPN functions are the most valuable features.
FortiGate provides solid protection against viruses, malware, and other threats.
In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable.
What stands out positively about Cisco is their training and support, which has effectively prepared engineers to work with their products.
This is very important to my organization, as we work extensively with security because we are a bank, so we can keep the data safe.
Cisco Secure Firewall allows me to safeguard Layer 7 or Layer 3 and manage the security rules with the business needs of my organization.
For SMB segments, SonicWall performs well.
It was beneficial during COVID for remote work through its VPN functionality.
The advanced gateway security features such as web filter, application control filter, IPS, ideas, gateway antivirus, anti-spyware, and botnet filter are valuable.

Jorge Martínez - PeerSpot reviewer
Offers good SD-WAN capabilities and integrates easily with Fortinet devices
I am not part of the initial setup or deployment process since I work in presales. The setup or deployment is quite easy, as you can do a one-touch deployment that automatically connects to the FortiManager cloud when you connect it to a broadband or dynamic IP, allowing you to start the configuration from that point. We usually sell it for on-premises setups. It's on the cloud only when the client has virtual machines or their own service. Sometimes they have a service on the cloud like AWS, but it's more difficult to sell now because AWS has an e-commerce option where you can buy FortiGate directly. The only thing you need is someone to manage and configure.
Carlos Reis - PeerSpot reviewer
Proven reliability and strong support spark trust but system updates slow and complex
The Cisco Secure Firewall product in general has room for improvement. I had a problem this weekend working with one of them, and I think it's very specific, though I'm going to be more general with my answer. Cisco has the FMC as a centralized tool, but sometimes they have too many dependencies. I faced a problem this weekend because while trying to solve an issue with one of the company's firewall management centers, I couldn't update or install an update on the platform due to a remote site being down. The device got stuck in my queue. I had to cancel my maintenance because of that. Everyone was expecting me to fix many bugs, but because of one device, I had to cancel everything. Sometimes the ID is nice around Cisco, but another area they need to improve is the capability to manage multiple devices. The FMC manages many devices, but if I put too many, around 300 devices, it becomes very slow, and the system becomes heavy. When you compare that with solutions such as Palo Alto, Palo Alto can manage many more devices on the same type of platform. Cisco is better at managing things such as RMAs. They do that exceptionally, even with the support. However, when we're talking about the FMC itself, sometimes they have some small issues; the platform is very slow and has too many bugs in the versions. We constantly need to update the platform to maintain stability.
Rias Majeed - PeerSpot reviewer
Robust VPN integration stands out despite needing enhanced vendor compatibility
The integrated VPN functionality is working well with the global VPN client, which is a fast client, though it comes at a cost. SonicWall TZ is functional depending on the service level taken by the user. For SMB segments, SonicWall performs well. Despite lacking certain features, it is still considered a good product. The appliance itself is functional and stable, offering integrated solutions.

Cisco ASA vs. Palo Alto Networks
Cisco ASA vs. Palo Alto: Management Goodies You often have comparisons of both firewalls concerning security components. Of course, a firewall must block attacks, scan for viruses, build VPNs, etc. However, in this post I am discussing the advantages and disadvantages from both vendors concerning…
