Cloud gateway has strengthened remote web security and now needs better Mac and ISP support

The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Browser security has strengthened web DLP and protects unmanaged devices from data exfiltration

SD-WAN capability is another solution, and it is not Prisma Access Browser; we do not have SD-WAN capability with Prisma Access Browser. I would like to improve the private access to do the ZTNA. I think that Palo Alto has released the versions and integrated the private access in Prisma Access Browser, but I'm not sure. The feature that is missing in Prisma Access Browser is the capability to monitor the private access where a user can access a private app with authentication, posture, and granular access. Regarding the pricing aspect, many customers find that the solution is a little bit expensive. Palo Alto should reconsider the pricing as it is a bit expensive.

Cloud security has transformed remote access and now supports zero trust for all users

The best features Zscaler Internet Access offers are Secure Web Gateway, URL filtering, SSL inspections, and policy-based access control. I find myself relying on Secure Web Gateway, URL filtering, SSL inspection, and policy-based access control the most because these are the main and top-most features I use regularly. Zscaler Internet Access has all of these types of features for securing all internet access and web inspections, allowing me to control all traffic through these features. Zscaler Internet Access features include a Secure Web Gateway for URL filtering, file type control, and inline SSL inspections. The second feature is a cloud firewall with Layer 3 to Layer 7 filtering control and stateful inspections. No hardware inspection or hardware firewall is required. I can also perform segmentations by users, location, and application. There is a cloud CASB solution available as well. Additionally, there is an advanced threat protection feature with signature-based behavioral detections, inline IPS, and zero-day threat protections. The cloud sandboxing solution scans unknown files and provides machine learning-based verdicts to prevent zero-day malware delivery in my environment. There is also a DNS security feature that provides DNS tunneling detections, malicious domain controls, and faster threat containment at the DNS layer. The data protection feature includes inline DLP and CASB-style cloud app control, data sovereignty enforcement, and browser isolation, which executes risky sites in isolated cloud browsers and prevents endpoint compromises. Zscaler Internet Access has positively impacted my organization by reducing the dependency on on-premises hardware and improving security posture, enabling faster user onboarding, and providing better performance for remote users. It has resulted in a drop in security incidents related to web threats and improved visibility into user activity. An area for improvement includes fine-grained troubleshooting tools, better policy simulations, and optimizations around initial configuration complexity.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I recommend iboss for organizations looking for strong cloud-based web security and centralized access control."

"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."

"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 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."

"Deploying iboss leads to good return on investment, estimated around 70% to 80%."

"It was a very easy product to install. It can be deployed very fast."

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

More iboss pros

"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."

"The most interesting use case that interests our customers is the DLP features on Prisma Access Browser; it is a great DLP solution with watermark and prevents data exfiltration."

"Prisma Access Browser is the most capable, advanced, and flexible product."

"Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income, improved our security environment control and endpoint protection, and it prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses."

"Zscaler covers all the features needed to replace a VPN or proxy solution; they are good, and they've been on the market for 15 years now, so they are mature enough."

"Zscaler offers a centralized DLP solution for web, endpoint, and email."

"It is easy to set up the solution."

"The scanning feature is impressive, because they do not introduce a big latency to the traffic."

"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote, so I have greater control site access and I minimize the number of compromises that we experience to almost none."

"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."

"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."

More Zscaler Internet Access pros

Cons

"The reporting feature needs improvement."

"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."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

"Its pricing could be better."

"To scale up, a new iboss Node Blade Chassis must be purchased."

"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."

"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."

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

More iboss cons

"The maturity of the product needs improvement as the implementation is very complex."

"On a scale of one to 10, I would rate Palo Alto's customer service or technical support as three. Their support is very poor."

"In the beginning, the solution may not be very user-friendly and could be complex."

"Regarding the pricing aspect, many customers find that the solution is a little bit expensive."

"The DLP part is quite crucial for this particular region."

"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."

"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."

"Zscaler Internet Access can improve by having more option for filtering policy which is currently only ip based (location policy)."

"There are a few features that are not compatible with the Azure cloud."

"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."

"The tool should improve the predefined dictionaries."

"The solution is quite expensive. It's around double what others are offering."

More Zscaler Internet Access cons

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."

"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."

"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."

"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

"The price of Zscaler Internet Access should improve, it is expensive."

"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."

"Our monthly fee is around R3000."

"It is costlier than other solutions."

"It is quite expensive. It does its job, but it is quite expensive for what we need."
