Sentiment score
7.4
Palo Alto Networks VM-Series offers high scalability and adaptability, with some configuration challenges but generally positive user experiences.
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.
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.
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.

8.1
Palo Alto Networks VM-Series is highly stable, with minor issues during updates, making it a robust choice for users.
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.
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

Cisco Secure Firewall faces criticism for its complex GUI, high costs, and demands better features, integration, and performance improvements.
Fortinet FortiGate struggles with integration, user complexity, support inefficiencies, high costs, and feature performance, needing improved documentation and security.
Palo Alto Networks VM-Series needs UI, reporting, integration, cloud compatibility, scalable features, clear pricing, and enhanced AI capabilities.
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.
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

Cisco Secure Firewall is costly but offers robust support and reliability; licensing complexity can be mitigated by smart licensing.
Fortinet FortiGate offers competitive, cost-effective pricing, appealing to small-medium businesses with flexible licensing and valued security solutions.
Palo Alto Networks VM-Series offers robust security and flexible pricing but requires careful licensing for cost-effectiveness.
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.
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.
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.

Fortinet FortiGate is user-friendly, cost-effective, and offers high-performance comprehensive security with advanced threat protection features.
Palo Alto Networks VM-Series offers advanced threat management, scalability, and security for cloud and data center environments with intuitive features.
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.
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.
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.

Featured Reviews

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.
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.

User-friendly CLI and efficient dashboard streamline operations with robust security features
I find Palo Alto Networks VM-Series easy to deploy, and none of my customers have had significant complaints. My customers have high certifications provided by Palo Alto Networks. The friendly dashboard and the ability to easily command and use the CLI make Palo Alto Networks VM-Series a better product. It offers robust solutions, making it valuable to my customers.

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…
