Enhances web security with a single pane of glass and flexible deployment
I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

Prisma Access browser enhances user security with isolation but demands improvements in customer support
The best feature of the Prisma Access Browser is browser isolation. Isolation makes the user experience very good and real-time, while the container is in a different zone. This is a great feature because if phishing or something happens, it doesn't impact the user's system. The same capability is provided by Zscaler with RBI and Netskope as well. Real-time threat monitoring for the Prisma Access Browser is good. It provides good data, and the customer was very happy. As part of the feedback, Palo Alto and I collected responses from them. They haven't faced any problems or false positives. The false positive scenario is less than 1% in Palo Alto.

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 pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Technical support is pretty sharp and very responsive."
"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."
"Prisma Access Browser improves security because the browser is one of the attack surfaces, it needs more security on the endpoint device and standardization of device usage, and it also helps standardize the access policy to the internet."
"Prisma Access Browser is the most capable, advanced, and flexible product."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"The initial setup is very straightforward."
"We don't have to buy equipment to use it. And when our engineers set it up on our side, we just configured a few settings and we were in."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"One on the main benefits is protection all time from anywhere."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
"The solution is stable."
"The solution is stable and reliable."
 

Cons

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"File integrity monitoring would be very advantageous as an additional feature."
"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 reporting feature needs improvement."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"In the beginning, the solution may not be very user-friendly and could be complex."
"The maturity of the product needs improvement as the implementation is very complex."
"Currently, the solution's interface is not that user-friendly."
"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."
"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."
"We'd like for them to include some sort of antivirus tool."
"One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."
"Cloud App’s database should be improved."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"The solution's pricing is on the higher side. It would be better if it could be lower."
 

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."
"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."
"It is probably in line with other solutions, but I do not deal with the financial side."
Information not available
"If we need any extra features, the price will increase."
"The price of Zscaler Internet Access should improve, it is expensive."
"We have found the solution to be expensive."
"It is a few pounds per user per month."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"Zscaler is transparent about its pricing model."
