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.

The logs and the reports allow me to have an overview of what is going on in my environment

The UI and the logs are a bit old school. I know that there is a plan to change some of those and update them to a newer view which will provide a better look and feel. I requested some changes to move buttons from one place to another so that the platform has more logic.

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 definitely recommend iboss for web filtering purposes to other organizations or individuals."

"As I mentioned, the return on investment is significant, as it saved our office locations' bandwidth because when you are working remotely at home, your internet traffic routes directly to iboss and will not go to your office building, saving bandwidth bottlenecks and ensuring that issues with our building internet circuits will not impact your internet connectivity because you are directly going to the iboss data center."

"The iboss system is highly reliable. The false positive rates are small compared to some other systems we've experienced through other partner agencies who use competing solutions."

"Technical support is pretty sharp and very responsive."

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

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

"iboss is definitely very good in terms of service."

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

More iboss pros

"The logs and the reports allow me to have an overview of what is going on in my environment."

"Cyren is simple to configure and deploy in all manners, saved us money, and for this type of service, this is value for money."

"The email service doesn't require any effort to configure, with no agents or internal virtual appliances."

"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."

"SSL inspection is a valuable feature."

"In summary, this is a good product and I completely recommend it."

"It securely transfers internet connectivity seamlessly, without any problems or issues."

"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."

"We have seen a lot of traction in the market and a lot of users adopting this solution, and we're able to control or manage all the remote locations from one place."

"The solution is stable."

"I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."

Cons

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

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

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

"I would like to see simpler dashboards, more detailed reporting, and faster performance in iboss."

"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."

"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."

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

More iboss cons

"The UI and the logs are a bit old school."

"One feature I am missing is the ability to connect automatically to internal monitoring systems."

"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."

"Currently, the solution's interface is not that user-friendly."

"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 tool should improve the predefined dictionaries."

"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."

"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."

"One thing that they could improve is the ability to import rules from other platforms."

Pricing and Cost Advice

"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."

"It is expensive compared to one of its competitors."

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

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

"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."

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

"We have found the solution to be expensive."

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

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

"The pricing for Zscaler Internet Access could be made cheaper."

Overview

iboss is the Zero Trust SASE platform that gives organizations complete visibility and governance over their AI, data, and applications through one unified platform, one console, one policy engine, and one data lake.

Your endpoints may already stop malware. Your data and application activity can still be invisible. iboss decrypts and understands every connection, then turns that signal into answers security leaders can act on.

The platform leads with three capabilities in this order: AI Security and Visibility, Data Security and Visibility, and App Visibility and Control. Zero Trust Network Access, VPN replacement, and SD-WAN sit underneath as the access fabric that carries those three. Trusted by global enterprises and government agencies.
