Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Unified security has protected diverse environments and supports consistent policies everywhere
I would say 8 out of 10 regarding the stability of Fortinet FortiGate. It requires a lot of bug fixing and what I understand, Fortinet is fast enough to provide bug fixes and patches, but usually I suggest Fortinet should do thorough testing of their releases and software releases and once probably they can reduce the frequency of new releases but make it stable. That's what my recommendation is. As far as the core objective of Fortinet FortiGate is concerned, I think they are meeting the targets but I guess for rolling out new features and new updates, they are doing a bit of hurry just to cope with the market dynamics. But possibly, I understand that they are compromising on the quality of the software and stability. So over there they have to improve. Rest of the aspects, I guess they are doing pretty good. We are happy. Regarding my experience with Fortinet FortiGate in comparison to maybe some other vendors such as CyberArk, Fortinet is in the top three and they give a lot of competition to their nearest peers in the market. But I guess Fortinet is really struggling in software-defined LAN, Wi-Fi, and FortiSwitches space. So they have to make their products more affordable in Forti-switching and Forti-WiFi space. They are not able to compete effectively with the nearest competitor HP Enterprise and HP Aruba.

Cloud security has transformed remote access and now supports zero trust for all users
The best features Zscaler Internet Access offers are Secure Web Gateway, URL filtering, SSL inspections, and policy-based access control. I find myself relying on Secure Web Gateway, URL filtering, SSL inspection, and policy-based access control the most because these are the main and top-most features I use regularly. Zscaler Internet Access has all of these types of features for securing all internet access and web inspections, allowing me to control all traffic through these features. Zscaler Internet Access features include a Secure Web Gateway for URL filtering, file type control, and inline SSL inspections. The second feature is a cloud firewall with Layer 3 to Layer 7 filtering control and stateful inspections. No hardware inspection or hardware firewall is required. I can also perform segmentations by users, location, and application. There is a cloud CASB solution available as well. Additionally, there is an advanced threat protection feature with signature-based behavioral detections, inline IPS, and zero-day threat protections. The cloud sandboxing solution scans unknown files and provides machine learning-based verdicts to prevent zero-day malware delivery in my environment. There is also a DNS security feature that provides DNS tunneling detections, malicious domain controls, and faster threat containment at the DNS layer. The data protection feature includes inline DLP and CASB-style cloud app control, data sovereignty enforcement, and browser isolation, which executes risky sites in isolated cloud browsers and prevents endpoint compromises. Zscaler Internet Access has positively impacted my organization by reducing the dependency on on-premises hardware and improving security posture, enabling faster user onboarding, and providing better performance for remote users. It has resulted in a drop in security incidents related to web threats and improved visibility into user activity. An area for improvement includes fine-grained troubleshooting tools, better policy simulations, and optimizations around initial configuration complexity.

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…

IT really depends on the type of business you had currently. These days almost all security vendors are offering Virtual Appliances so it's a preference based decision. Almost all vendors are offering basic features with some add-ons / additional features with differences among others competitors. Look at 1. FortiGate, 2. Cisco Meraki, 3. SOPHOS Products they all provide you flexibility to have...

There are several factors to consider: · In-house expertise to manage a physical firewall · Number of locations requiring a firewall · Current and planned linkage between office locations · Value of the information you want to protect I’m personally a fan of on-premise physical firewalls for high $ information to protect. However, if the $ risk is not particularly high, your in-house expertise to manage firewalls is low, and you have multiple locations to protect, I would recommend a security gateway service with VPN connections between your offices and the location of the security provider. I cannot recommend one supplier over another. If you choose to go with a physical firewall, Fortigate has a good reputation. Regards,

Depending what is your goal and where offices are based. When you want to protect your users in offices, then you would want to have kind of perimeter firewall (usually appliance) - standard (old) way. Fortinet is affordable and OK. When you wan't better check Palo Alto Networks. In case your offices are close (in milliseconds) to Zscaler cloud then you could also use this. Ask them to share information of their "cloud" locations and measure RTT from your offices. Note that all your traffic will go via Zscaler cloud (privacy, confidentiality). With Fortinet or similar appliance, you have possibilty to have VPN for your users with home office. Not sure when it's feasible with cloud solution from Zscaler. Like said really depends on where you are, what kind of business you are doing.
