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.

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

"The security aspect of the solution, particularly the malware behind it, is excellent."

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

"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."

"This product is solid, fairly easy to use, and reliable."

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

"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."

More iboss pros

"The solution's stability is good."

"It helps to secure the networks at the DNA level and ensure proper identification and filtering of DNS traffic."

"We can use Fortinet FortiProxy configuration for your network."

"The most valuable feature is intrusion prevention (IPS) and antivirus profiles. These features help control user activity, ensuring that they access only permitted websites and protects from downloading viruses."

"The most valuable features of Fortinet FortiProxy are its simplicity and performance."

"The App Control feature in the Fortinet FortiProxy Deep Packet Inspection (DPI): FortiProxy analyzes traffic at the application layer to detect applications even if they use non-standard ports or are encrypted."

"The tool's most valuable feature is traffic inspections."

"It seamlessly integrates with various security products, enhancing threat intelligence and improving indicators of compromise."

More Fortinet FortiProxy pros

"Zscaler Internet Access gives visibility, which is important to have, and the fact that it is usable everywhere is a significant advantage."

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

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

"The ROI of the solution is excellent."

"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 VPN is valuable, as the whole technology is very different from a traditional VPN."

"There is no lag in service when accessing the internet."

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

More Zscaler Internet Access pros

Cons

"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."

"Sometimes, obviously, there are bugs."

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

"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."

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

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

"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."

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

More iboss cons

"Its power supply process for some of the proxies needs improvement."

"Integration with existing infrastructure was generally easy, especially if you had tools like LDAP. However, I had to go through a lot of documentation as it was my first time working with a proxy server. We did experience some issues with certain web applications not working properly after implementing Fortinet FortiProxy."

"For me it may be the wildcards for URLs whitelist or blacklist, somehow the page loads."

"Fortinet FortiProxy should improve by adding more documentation and guides."

"I see that the solution's interface is not in French...It would be good for our company if we could have the tool interface in French."

"Fortinet FortiProxy should integrate AI/ML technologies. Its pricing needs to be more flexible."

"Its web filtering capabilities could be improved."

"For IT administrators and managers, the reporting features are the main issues that should be addressed in order to improve the performance, security, and effective utilization of the product."

More Fortinet FortiProxy cons

"Every client decided to purchase professional services because deploying Zscaler Internet Access is too complex."

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

"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."

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

"An improvement would be if they could provide an out-of-the-box experience, like 20 to 30 features all ready to go. In comparison, LogRhythm offers out-of-the-box features. With Zscaler Internet Access, there is firewall IPS, multiple security services, filtering, DLP, and CASB browser isolation. These are things that all users are going to be using. However, when an administrator or architect would start building this, I would definitely need to engage professional services to help clients do it."

"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."

"What could be improved in Zscaler Internet Access is its price. It could be cheaper."

"The performance needs improvement. Some areas create performance issues and, depending on the use cases, require reconfiguration to perform again."
