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

"Its initial setup was straightforward."
"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."
"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."
"The console is cloud-based, which is something I really appreciate."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"The security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"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."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"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."
"SSL inspection is a valuable feature."
"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"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."
"Zscaler Internet Access's best feature is the granular policy controls."
 

Cons

"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"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 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."
"The dashboards for local use could be better."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"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."
"The solution is expensive. They recently revised the pricing and packaging. Some of our existing customers have been asking for alternate solutions for a lower price."
"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
"The solution's pricing is on the higher side. It would be better if it could be lower."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"They could provide more time for the onboarding the training of an IT person."
"Zscaler Internet Access could improve by adding a VPN feature."
"In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution."
"We'd like to have more plugins and integration."
 

Pricing and Cost Advice

"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."
"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 expensive compared to one of its competitors."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
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."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"The pricing is fair based on its competitive market."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The tool is moderately priced."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"​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 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."
