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.

Secure hybrid environments with robust cyber threat protection
The most valuable features are ZTNA 2.0, CASB, Threat Prevention, and Autonomous Digital Experience Management (ADAM). These features are security-driven, providing robust protection against increasing cyber threats by integrating NG Firewalls, SD WAN, and CASB, all within a fully cloud-native solution. This enables easy integration with both legacy and modern platforms, allowing enhanced leverage and scalability.

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

"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."
"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."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"The console is cloud-based, which is something I really appreciate."
"Our primary use case for this product is DLP,"
"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 has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."
"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"The most valuable feature is the ability to change the gateway. For example, if there's a problem with a specific region or vendor, we can make modifications. The solution is scalable, and there are different gateways that can be created depending on the demand."
"Palo Alto Firewall is one of the best firewalls in the world."
"Prisma Access by Palo Alto Networks makes our life easier because the firewall solution we had before was totally outdated and performing poorly. This solution has completely transformed our operations."
"A feature I've found very helpful is run time security because most of the products on the market will look at security during the build time, and they don't really look at what happens once you're going into production."
"Its frontend is user-friendly. It is easy to use for us."
"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."
"The Autonomous Digital Experience Management (ADEM) offered by Palo Alto is a good reporting tool. It gives insights into how things are going within the network. It takes all the data from the users' endpoints and does an analysis, and it suggests changes as well."
"It is easy to use, easy to integrate, and is stable. It's scalable as well."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"Zscaler Internet Access integrates effectively, especially with the high-level IP services."
"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."
"We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."
"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."
"There is no lag in service when accessing the internet."
"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."
 

Cons

"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"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."
"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."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"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 reporting feature needs improvement."
"Sometimes a third-party outage could impact the whole operability."
"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."
"It is a managed firewall. When you run into issues and have to troubleshoot, there is a fair amount of restriction. You run into a couple of restrictions where you don't have any visibility on what is happening on the Palo Alto managed infrastructure, and you need to get on a call to get technical assistance from Palo Alto's technical support. You have to get them to work with you to fix the problem. I would definitely like them to work on the visibility into what happens inside Palo Alto's infrastructure. It is not about getting our hands onto their infrastructure to do troubleshooting or fixing problems; it is just about getting more visibility. This will help us in guiding technical support folks to the area where they need to work."
"The frequency of updates could be reduced."
"Lacks a hybrid model which has API plus in-line security."
"When we deploy firewall rules via Panorama, we find it's a little bit slow. We have a global environment and might have 100 gateways or VPNs in the cloud. When we deploy something, it tries to deploy it one-by-one, and that can be slow."
"Its integration with non-Palo Alto products can be improved. Currently, it is easy to integrate it with other Palo Alto products such as Cortex XDR. It integrates well with other Palo Alto products. A major part of our network is based on Palo Alto products, but for those companies that use multi-vendor products in their infrastructure, Palo Alto should optimize the integration of Prisma Access with the network devices from other vendors."
"The solution’s stability could be improved."
"Sometimes, support isn't available."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"The OS capabilities and WSL support could be improved."
"Currently, the solution's interface is not that user-friendly."
"Zscaler Internet Access could improve by adding a VPN feature."
"In terms of user experience, it could be better."
"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP. This is a bit problematic."
"The tool should improve the predefined dictionaries."
 

Pricing and Cost Advice

"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."
"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."
"It is expensive compared to one of its competitors."
"The overall pricing for iboss is very competitive and transparent."
"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."
"As compared to other solutions, Prisma Access is much cheaper. It is probably 30% to 40% cheaper than other solutions, but I do not know the exact cost."
"There's no reason not to buy the enterprise version that gives you unlimited PoPs, but you must understand the limitations you impose on yourself if you do that. If you go crazy, that allowlist will be too big for Kubernetes clusters."
"Prisma Access is one of the best compared to other products on the market. The cost is favorable, and Palo Alto provides a simple architecture, so I recommend the solution to anyone using a different product. There are no hidden costs besides the license; what you see is what you get."
"The solution is expensive."
"Prisma Access is a little bit expensive."
"Compared to other products, the price is slightly high."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"The pricing for Zscaler Internet Access could be made cheaper."
"It is costlier than other solutions."
"The pricing is fair based on its competitive market."
"The price is competitive. It's not cheap and it's not expensive."
"We have found the solution to be expensive."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"The tool is moderately priced."
