Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
5.7
Users find Fortinet FortiGate cost-effective, enhancing security and productivity while reducing operational costs and manpower needs.
Sentiment score
8.1
Cisco IOS Security offers high ROI through improved efficiency, reduced risks, cost savings, and a beneficial subscription model.
Sentiment score
6.7
Sophos XG offers comprehensive security and cost-efficiency, with reduced personnel costs and simplified configurations, despite initial expenses.
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 graphical interface of Sophos XG simplifies configurations, saving time in support and troubleshooting compared to the Linux-based solution I previously used.
We purchased endpoint security for the first time last year, and even without endpoint security, it provides comprehensive security.
It's good, but I would still say it's higher by about 10-15 percent compared to other market products with similar configurations.
 

Customer Service

Sentiment score
6.4
Fortinet FortiGate's customer support is generally positive but varies in responsiveness and expertise, influenced by region and support tier.
Sentiment score
7.0
Cisco IOS Security offers expert support but faces criticism for slow responses and communication challenges, remaining a strong choice.
Sentiment score
6.4
Sophos XG support receives mixed reviews, praised for expertise but criticized for delays and inconsistent service from external centers.
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.
They are professional, respond quickly, and help resolve issues effectively.
I rate the technical support a ten out of ten.
Their team was quick to diagnose and resolve the problem by exchanging the equipment within two weeks.
 

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
7.5
Cisco IOS Security is praised for scalability and efficiency but may require additional hardware and specific Cisco equipment.
Sentiment score
7.0
Sophos XG scales for different organizations with cloud-based flexibility, despite hardware limits, supporting small to medium businesses effectively.
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.
You can scale up to multiple firewalls with centralized management.
You can't upgrade memory or storage on a specific model, which limits scalability.
I rate the scalability a nine out of ten.
 

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
7.7
Cisco IOS Security is praised for stability and reliability, with few integration issues reported when not using Cisco equipment.
Sentiment score
7.9
Sophos XG is praised for strong stability and reliability, despite occasional bugs and increased resource demands with updates.
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.
Sophos XG is very stable, even when serving as a DHCP server.
Sophos XG is resource-greedy, affecting performance even on newer computers.
It's on 24/7 and has consistently been reliable over the years.
 

Room For Improvement

Fortinet FortiGate struggles with integration, user complexity, support inefficiencies, high costs, and feature performance, needing improved documentation and security.
Cisco IOS Security needs more intuitive management, better performance, advanced features, and improved integration, usability, and support.
Sophos XG users seek improved UI, integration, performance, VPN setup, support, reporting, protection, SD-WAN capabilities, pricing, and documentation.
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.
The solution should have the ability to be up to date with the most recent threats.
This suggests a vulnerability that needs addressing to ensure administrators can update patches without losing access.
Business cannot stop just because of issues with support.
 

Setup Cost

Fortinet FortiGate offers competitive, cost-effective pricing, appealing to small-medium businesses with flexible licensing and valued security solutions.
Cisco IOS Security is pricey, subscription-based, aimed at medium-to-large enterprises, with recent SMB options, often seen as expensive.
Sophos XG offers competitive pricing, especially with bundles and discounts, though some users dislike recurring annual licenses.
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.
I rate the pricing a ten out of ten.
Currently, it costs about four million shillings in Kenya.
The cost depends on the package you are in, such as full threat management or basic.
 

Valuable Features

Fortinet FortiGate is user-friendly, cost-effective, and offers high-performance comprehensive security with advanced threat protection features.
Cisco IOS Security enhances network security with robust features, user-friendly interface, and strong performance, preferred over competitors.
Sophos XG boasts intuitive interface, efficient filtering, VPN flexibility, centralized management, cloud support, and robust security features.
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.
I particularly like the visibility it provides into network traffic, allowing us to identify and address issues efficiently.
The firewall feature of Sophos XG has been the most effective for threat prevention.
Integration with endpoint security products ensures seamless traffic flow and rule enforcement, even when endpoints are not directly connected to the firewall.

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.
Binoob John - PeerSpot reviewer
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…
TarunPanchal - PeerSpot reviewer
Decades of expertise lead to seamless installations and robust security
I typically use the Sophos XG Firewall to enhance my cybersecurity by using all layers. The intrusion prevention system impacts my security posture effectively, as we have not faced any ransomware or cyber threats. I have more than 800 servers live from Sophos. The synchronized security feature has proven to be very beneficial, and I have not encountered any issues. Sophos XG Firewall has contributed to reducing overall costs because it helps save money. We purchased endpoint security for the first time last year, and even without endpoint security, it provides comprehensive security. Sophos XG uses AI effectively to enhance threat detection and response, securing from AI at the packet level.
