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.

Cloud features enhance security measures and simplify network management
I've dealt with many firewalls, such as SonicWalls, UniFi, pfSense, and Cisco. We found SonicWall very confusing for the average network engineer or network administrator. I don't recommend SonicWall due to its hard-to-find auditing process for exploits. Although they have fewer exploits, when they do occur, they're significant. With Fortinet FortiGate, you can access the whole firewall, with no hidden spots. pfSense is great, however, it requires a lot of manual work and has no Cloud Connect or easy management from an MSP's perspective. Palo Alto is another option that's great, but their price point isn't for everyone, especially for medium and small businesses; a $10,000 investment doesn't necessarily fit into most budgets. UniFi is another product we've started to use more alongside Fortinet FortiGate, as they have almost all features without a license, with advanced rules that are relatively inexpensive compared to Fortinet FortiGate's $1,500 a year. Fortinet FortiGate and UniFi are the two firewalls we primarily deal with. My opinion is that UniFi has better integration and oversight of the environments compared to Fortinet FortiGate.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

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.
