7.4
Cisco IOS Security offers scalable, enterprise-level solutions but may increase costs and limit universality due to required hardware.
Sentiment score
7.3
Cisco Secure Firewall offers scalable solutions with adaptable clustering, despite some licensing concerns, enhancing integration and management ease.
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.

Sentiment score
7.7
Fortinet FortiGate is praised for its dependable stability, minimal downtime, and robust performance, especially with regular firmware updates.
Sentiment score
7.6

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 find Cisco products stable and thoroughly tested before new software or firmware versions are released.
I find Cisco IOS Security to be a very stable product.
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.
 

Room For Improvement

Users seek improvements in FortiGate's performance, web interface, reporting, documentation, licensing, and training resources.
Cisco IOS Security struggles with integration, usability, cost, lacking features, complex licensing, performance, and requires enhancement and support.
Cisco Secure Firewall is hindered by complex UI, licensing issues, outdated features, and needs improvements in scalability and integration.
Investing in a solution that can accommodate such growth would be more cost-effective than repeatedly purchasing new hardware.
While Fortinet claims to offer a comprehensive network solution, it falls short in addressing computer application issues, particularly server security.
When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
Cisco changes their licensing policy quite frequently, which is becoming confusing and complicated.
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.
 

Setup Cost

Fortinet FortiGate offers robust features at a competitive price but can be costly, especially with licenses; long-term pricing negotiation advised.
Cisco IOS Security is costly, favoring medium to large enterprises with longer-term savings over SMB challenges.
Cisco Secure Firewall has high pricing and complex licensing, with significant ongoing costs despite potential discounts.
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 offers cost savings as it is generally cheaper than the competition.
It is about 20% cheaper.
The cost of Cisco IOS Security for customers is on the higher end of pricing compared to the competition, depending on the targeted customers.
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.
 

Valuable Features

Fortinet FortiGate provides robust security, seamless integration, user-friendly interface, and cost-effective advanced threat management for diverse network environments.
Cisco IOS Security offers scalable, stable solutions with VPN, AAA, firewall integration, and user-friendly management for high-demand environments.

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.
The best features of Cisco IOS Security are its integration with software management tools such as Cisco DNA Center and Cisco ICE, which provide centralized policy and network access control.
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.

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.
Danijel Cerovecki - PeerSpot reviewer
Have faced challenges in keeping licensing clear and consistent while ensuring reliable network protection
We are a Gold Partner with Cisco. Our customers come from various industries, including service providers, and we target service providers and enterprise customers.We do not extensively use Zone-Based Firewalls in Cisco IOS Security, instead typically deploying standalone firewalls such as Cisco FTDs or Cisco ASA devices. For threat analytics and vulnerability scanning, we utilize third-party vendors with dedicated devices and software. We use products such as Tenable from Nessus for this type of analysis. We have implemented Secure Access Control Server in Cisco IOS Security, which combines multiple security mechanisms including AAA, 802.1X for network access control with Cisco ICE, TrustSec for identity-based segmentation, and Cisco DNA Center. Cisco IOS Security's VPN support is comprehensive and increasingly important in daily communication, from basic site-to-site tunnels to remote access VPNs and SD-WAN secure VPNs. Protecting and encrypting communication is essential in modern networks. The challenges with Cisco IOS Security are more operational than product-related. There is an understaffing issue, making automation and orchestration capabilities particularly valuable. For the products themselves, we only encounter routine operational matters such as addressing new vulnerabilities and patching. For those considering Cisco IOS Security, it is important to understand that Cisco offers a complete ecosystem. When embracing the Cisco ecosystem fully, customers receive excellent products and comprehensive solutions. On a scale of 1-10, I rate Cisco IOS Security a 9.

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.
