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.

Granular control over website access has lead to decreased bandwidth and increased performance
If you have previously worked on the product then it is quite simple. However, if you are new to it then the implementation is a little bit tricky. On the Cloud Proxy, the deployment takes less than one day. If you are using the ProxySG or the on-premises solution, it will take one to two weeks depending on the policy configuration, the size of the organization, and what kinds of policies are needed. The number of staff you need to maintain the solution depends on the size of the organization, and how many changes occur on a daily basis. If you have one thousand employees then you need at least one employee to look after it.

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.

Quotes from Members

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

Pros

"Technical support is pretty sharp and very responsive."
"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Content filtering is the most useful feature of iboss."
"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."
"iboss is definitely very good in terms of service."
"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."
"Technical support is pretty sharp and very responsive."
"Proxy Solution and ADN and their integration capability with Blue Coat director are positive features."
"Customer Service: Blue Touch support is top notch and very responsive when I opened service requests."
"It features intuitive proxy policy deployment using a VPN."
"It's a great solution for high load enterprise infrastructure to protect company networks from web threats."
"Since the implementation of this solution, the bandwidth has decreased and the performance in terms of Internet access has increased."
"Proxy Solution and ADN, specifically its integration capability with Blue Coat Director to apply seamless policy across all of Blue Coat, along with intuitive proxy policy deployment using VPN and the ability to forward-chain your proxy, make it overall a good solution though growth requires automation support."
"We were able to monitor users' social media behavior and control certain activities to be allowed on the social media, which helped to prevent data loss and other activities that could result in a negative impact to the organization."
"The functionality of this solution is one of the best, and it is leading the market."
"Zscaler offers the best service since you are protected wherever you are."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"The most valuable feature is the ability to drop packets."
"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
"The main benefit that we have seen is performance improvements based on not having to backhaul traffic and getting cloud services closer to the user."
"Zscaler covers all the features needed to replace a VPN or proxy solution. They are good. They've been on the market for 15 years now, so they are mature enough."
"The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
 

Cons

"iboss can be improved because the integration could be better; you need to import all the sites that you access today, and there are a few problems whenever you import thousands of websites, making the integration process messy for the users."
"The reporting feature needs improvement."
"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."
"Sometimes, obviously, there are bugs."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"The dashboards for local use could be better."
"They need to improve the intellectual analysis for APT vectors from web."
"We cannot automate the product since the IP address can only be assigned after acquisition of the serial number."
"Blue Coat advertises the ProxySG as a WAF, but it really isn’t."
"The GUI works, but could be better."
"It lacks deployment over multiple platforms and integration with SDN architecture."
"There were benefits but the evolution is slow, hence wanting to move on with the product."
"It would be great if the product had inbuilt queuing for Quality of Service."
"It would be great if the product had inbuilt queuing for Quality of Service."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"The solution is expensive. They recently revised the pricing and packaging."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective."
"Zscaler Internet Access can improve by having more option for filtering policy which is currently only ip based (location policy)."
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
 

Pricing and Cost Advice

"We had the cost of purchasing a new appliance along with the implementation and licensing costs. However, the following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs."
"The overall pricing for iboss is very competitive and transparent."
"It is not expensive, and it is also not cheap. iboss is priced right in the sweet spot for the number of features it offers."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"It is expensive compared to one of its competitors."
"It is probably in line with other solutions, but I do not deal with the financial side."
"Additional features, such as Flash Proxies, have their own licensing fees that depend on what the requirements are."
"We have found the solution to be expensive."
"It is a few pounds per user per month."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"It is costlier than other solutions."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"Zscaler is transparent about its pricing model."
"The price of Zscaler Internet Access should improve, it is expensive."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
