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

"The iboss solution gives me the ability to scan the traffic through all the ports, through all the 131,000 PCP and UDP ports, and with this ability, we have the granularity also for consults over social media and applications on mobile, and this is an advantage that the customers are looking for right now."

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

"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."

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

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

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

"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."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

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 data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go."

"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."

"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."

"The most valuable feature is the ability to drop packets."

"The solution has reduced cyberattacks."

"Zscaler has helped protect our employees wherever they are working, by delivering safe web access."

"Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."

"The solution is scalable and stable."

More Zscaler Internet Access pros

Cons

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

"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, and that is where in 2025 we had to migrate to the Palo Alto-based platform."

"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."

"iboss can be improved because the integration could be better; you need to import all the sites that you access today, and there are a few problems whenever you import thousands of websites, making the integration process messy for the users."

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"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."

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

"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."

More iboss cons

"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."

"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."

"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."

"In terms of user experience, it could be better."

"I would really like to see the elimination of these confusing PAC files for how Zscaler Internet Access could be improved."

"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."

"We'd like for them to include some sort of antivirus tool."

"They could provide more time for the onboarding the training of an IT person."

"It also needs better integration with other applications as well. There are some restrictions."

"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."

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."

"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."

Information not available

"Our monthly fee is around R3000."

"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."

"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."

"The price is competitive. It's not cheap and it's not expensive."

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

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

"We have found the solution to be expensive."

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