Scalability Issues

7.1

Sentiment score
7.5
Cisco IOS Security is praised for scalability and efficiency but may require additional hardware and specific Cisco equipment.
Sentiment score
7.6
Palo Alto Networks VM-Series is scalable, satisfying users despite some cloud integration challenges, and suitable for diverse enterprises.
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.

Sentiment score
7.7
Cisco IOS Security is praised for stability and reliability, with few integration issues reported when not using Cisco equipment.
Sentiment score
8.3
Palo Alto Networks VM-Series is praised for stability and reliability, despite occasional bugs and manual interventions during upgrades.
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.
I find Cisco IOS Security to be a very stable product.
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 could improve its UI, stability, integration, and support, with high costs and complex setups being challenges.
Cisco IOS Security needs more intuitive management, better performance, advanced features, and improved integration, usability, and support.
Palo Alto Networks VM-Series needs better integration, scalability, documentation, cloud compatibility, and improved features to address user concerns and performance.
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 cost-effective pricing with competitive long-term contracts, appealing to small and medium-sized enterprises.
Cisco IOS Security is pricey, subscription-based, aimed at medium-to-large enterprises, with recent SMB options, often seen as expensive.
Palo Alto Networks' VM-Series pricing is high but justified by advanced security features, with flexible licensing aiding budget management.
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.
 

Valuable Features

Fortinet FortiGate provides advanced security features, user-friendly management, and enhanced network performance with cost-effective, regularly updated solutions.
Cisco IOS Security enhances network security with robust features, user-friendly interface, and strong performance, preferred over competitors.
Palo Alto Networks VM-Series excels in threat prevention, scalability, and user-friendly management, integrating advanced security features and cloud services.
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.
This solution, called Network Access Controller, handles authentication, authorization, and accounting for devices accessing the network.
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.

Rrobust network security and device authentication with advanced access control features
This solution should be implemented for most enterprise-level customers. It ensures that users accessing the corporate network or wireless network with their own devices are authenticated and authorized. As a network administrator, I can track who is accessing the network, what devices they are…

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.
