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.

Zero-trust access has improved remote security and now simplifies cloud-based firewall management
Regarding the integration part for Prisma Access by Palo Alto Networks, the integration with identity providers is pretty much good. It is basically firewall as a service, so it performs well. I completed the integration without any issues. What Palo Alto Networks can do better for Prisma Access by Palo Alto Networks is probably to have the point of presence available in more locations. The point of presence from the Serbia region has the nearest POP in Frankfurt, which is an issue since it is your gateway—when you start browsing the internet, you go through a commercial connection in Germany. They definitely need to spread the service in other countries.

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

"It was a very easy product to install. It can be deployed very fast."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"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."
"Technical support is pretty sharp and very responsive."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"It protects all app traffic so that users can gain access to all apps. Unlike other solutions that only work from ports 80 and 443, which are predominantly for web traffic, Prisma Access covers all protocols and works on all traffic patterns... The most sophisticated attacks can arise from sources that are not behind 80/443."
"There are plenty of features this solution provides and the most valuable would be the complete security protection we are receiving. We are provided with similar security that the Palo Alto AWS solution has. This includes features such as a firewall and machine learning AI."
"The solution also provides traffic analysis, threat prevention, URL filtering, and segmentation. That combination is important because it enhances the protection and makes the traffic more secure. It also keeps things more up-to-date, enabling us to deal with more of the current threats."
"It is easy to use, easy to integrate, and is stable. It's scalable as well."
"Customers are quite happy with Prisma Access by Palo Alto Networks because there is less spending on technologies."
"The initial setup is very straightforward."
"Its hands-off security and the fact that we don't have to maintain it are the most valuable features."
"Prisma helped us build a moat around our production systems. It's now impossible to log into our production from a non-MDM laptop. Prisma Access provides decent security overall."
"The initial setup is very straightforward."
"The solution's most valuable features are its reliability and availability, measured by the number of ports it offers."
"Tech support is good."
"Zscaler Internet Access's best feature is the granular policy controls."
"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."
"Zscaler Internet Access's roaming user feature is most valuable and is much better compared to other secure web gateways."
"The solution is stable and reliable."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
 

Cons

"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."
"I am currently doing a PoC of the zero trust aspect of it. Compared to other similar solutions, it is hard to get around each feature. It takes a while to get used to it."
"Its pricing could be better."
"The dashboards for local use could be better."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."
"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."
"There should be a dedicated portal or SASE-based solution. They're trying to add a plugin but it needs a dedicated portal because it is now an enterprise solution for multiple organizations. People should be able to directly log in to a dedicated page for Prisma Access, rather than going into a Panorama plugin, and always having to update the plugin."
"The documentation is generally good, but they could provide a more detailed description of all the configuration steps. I have to search for information or call support. Palo Alto could add more knowledge base articles about configuration with screenshots and walkthroughs. That would be helpful. When configuring a product, you want to see examples of how it is done."
"Better integration with the MDM solution would be useful."
"Though the monitoring is fine, the solution should improve its application graphs and interface monitoring."
"The Cloud Management application has room for improvement. There are a lot of things on the roadmap for that application; things are going to happen soon."
"Prisma's integration between operational technology and IT should be more seamless. Right now, it requires additional setup and maintenance."
"The licensing model isn't flexible enough. It's an all-or-nothing model. Other providers in the market allow you to buy modules or add-ons separately. With Prisma Access, you have to purchase the same module for all users."
"My clients are not satisfied with the technical support from Palo Alto Networks."
"Zscaler needs to add client-to-client communication. It's always client-to-server communication. The cloud and branch connectors could be improved because we're still dependent on traditional firewalls. They should eliminate this. They should also provide WAN devices should to compete with the SD-WAN solutions also."
"The OS capabilities and WSL support could be improved."
"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."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"We'd like for them to include some sort of antivirus tool."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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 expensive compared to one of its competitors."
"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 pretty expensive. We have to balance the cost of some features. They need to work on some of the services and products, price-wise."
"The pricing is very friendly. It's not confusing to figure out your workload and how much you'd be paying for the solution."
"The pricing for this solution is on the higher end."
"It's pricey, it's not cheap. But you get what you pay for."
"I'm still comparing, but the solution is quite expensive."
"In terms of pricing, considering that it is a two or three years old solution, they should apply big discounts for the next two or three years. This approach will be better for them to capture the market."
"We have to pay additional costs for maintenance and support services."
"The licensing fees are paid on a yearly basis and for what we get, the price is good."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"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."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"It is costlier than other solutions."
"The pricing is fair based on its competitive market."
"Zscaler is transparent about its pricing model."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
