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 would rate the technical support of iboss a solid 10 without a shadow of a doubt."

"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."

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

"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."

"Our primary use case for this product is DLP,"

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

"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 students were always protected, and the content filtering worked very well, seeming to work better than other products we had tried previously."

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."

"The most valuable features of Zscaler Internet Access include its capacity to scale, the security implementation capabilities, the ability to integrate public IPs related to clients so traffic presents on the internet as a client, and the facility to interoperate with SSEs while maintaining the same security mechanisms from on-premises to cloud environments."

"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."

"After a proper implementation, the maintenance is very low."

"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."

"The cloud proxy and integration are some of the key features. Since there is cloud waste, we can quickly provision it and start working on the configuration. On top of that, they have added a few more features. They have integrated CASB, and file sandboxing is part of it."

"Zscaler Internet Access has positively impacted our organization by improving our overall security posture, providing better visibility into the internet traffic our employees access, and protecting users from web-based threats such as phishing websites, malicious downloads, and suspicious sites."

"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."

"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."

More Zscaler Internet Access pros

Cons

"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."

"The endpoint-type solution is an area that needs some improvement."

"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."

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

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

"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."

"I have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."

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

More iboss cons

"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."

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

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

"We use other similar products and find them to be a bit more preferable to Zscaler."

"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."

"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."

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

"The solution's pricing is on the higher side. It would be better if it could be lower."

"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."

"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."

"The current reports can, therefore, be somewhat improved and simplified."

More Zscaler Internet Access cons

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."

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

"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."

Information not available

"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."

"If we need any extra features, the price will increase."

"The pricing is an issue. It is expensive compared to other firewalls on the market."

"The pricing is fair based on its competitive market."

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

"It is a few pounds per user per month."

"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."

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