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.

Stable product with essential document tracking features
In my organization, we worked with around ten to fifteen different technologies, including Bitglass, and CASB was not among our top priorities. While CASB might benefit some organizations, it was optional for our specific setup, considering the other security measures and technologies we had in place. I found no particularly valuable features regarding CASB resolutions. There are other tools available that can achieve the same functionalities and perform similar tasks. For example, I can accomplish tasks like encryption or secure data movement from our office to the internet using alternative services like Zero Trust solutions. Because of this, our organization considered removing it from our system due to its limited benefits compared to other products.

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

"iboss is definitely very good in terms of service."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"It was a very easy product to install. It can be deployed very fast."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Our primary use case for this product is DLP,"
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"From stability and availability standpoints, it is pretty good."
"The product is stable."
"The quarantine feature is the solution's most valuable aspect."
"The quarantine feature is the solution's most valuable aspect."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"The most valuable feature is bandwidth control."
"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."
"The protection is most valuable."
"The solution’s customer service is good."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote, so I have greater control site access and I minimize the number of compromises that we experience to almost none."
"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
"What I like most about Zscaler Web Security is that we can have our users protected from internet threats and viruses even when they're not connected to our network."
 

Cons

"The area I would like to see improvement in is the ability within the reporter to navigate directly to the content the user is traversing."
"The dashboards for local use could be better."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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, and that is where in 2025 we had to migrate to the Palo Alto-based platform."
"The dashboards for local use could be better."
"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"I think some of the hiccups that we had were with the number of domains that we had and how that had to be implemented in Proofpoint."
"Proofpoint Cloud App Security Broker should be cheaper."
"They are priced significantly higher and less cost-effective than alternative options."
"The TLS encryption needs to be improved. It's not state of the art."
"The TLS encryption needs to be improved. It's not state of the art."
"I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again."
"Zscaler Internet Access could improve by adding a VPN feature."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"There are many functionalities in Zscaler Internet Access that need improvements, such as an advanced firewall and logging capabilities to track calls."
"Zscaler Internet Access can improve by having more option for filtering policy which is currently only ip based (location policy)."
"Zscaler is one solution. It's a good solution, but it doesn't do everything."
"Sometimes, support isn't available."
 

Pricing and Cost Advice

"It is expensive compared to one of its competitors."
"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
"The overall pricing for iboss is very competitive and transparent."
"It is probably in line with other solutions, but I do not deal with the financial side."
"We had an enterprise contract with them for about 32,000 users at that point, which has now grown."
"The tool's most valuable feature is reporting. It helps us understand what's going on in our environment."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"Zscaler is an expensive solution, but it's worth the price. Their services are unmatched by competitors. Some may come with half the features that Zscaler can offer and be much cheaper. However, they do not have the global coverage that Zscaler has, and they will not provide the same low latencies and the same speeds that Zscaler can."
"We have found the solution to be expensive."
"The tool is moderately priced."
"The pricing is fair based on its competitive market."
"If we need any extra features, the price will increase."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
