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 among the few products providing inline filtering where no application is needed on the device."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."
"Technical support is pretty sharp and very responsive."
"Our primary use case for this product is DLP,"
"Its initial setup was straightforward."
"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."
"Content filtering is the most useful feature of iboss."
"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."
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
"The solution is stable and reliable."
"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."
"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 solution’s customer service is good."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"Zscaler Internet Access's best feature is the granular policy controls."
"Overall, we're very happy with our product."
 

Cons

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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."
"The maturity of the product needs improvement as the implementation is very complex."
"In the beginning, the solution may not be very user-friendly and could be complex."
"There are a few features that are not compatible with the Azure cloud."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"The admin UI and documentation for Zscaler Internet Access could be more intuitive for new users, specifically during initial rollout and advanced policy design."
"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."
"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."
"Currently, the solution's interface is not that user-friendly."
"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. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."
"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."
 

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."
"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."
"It is probably in line with other solutions, but I do not deal with the financial side."
"It is expensive compared to one of its competitors."
"The overall pricing for iboss is very competitive and transparent."
Information not available
"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."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"There are multiple bundles: enterprise, business, and transformation. Transformation includes all the features, but recently I've seen a few more line items that are additional costs. Overall, it's expensive."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
