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.

Granular control over website access has lead to decreased bandwidth and increased performance

If you have previously worked on the product then it is quite simple. However, if you are new to it then the implementation is a little bit tricky. On the Cloud Proxy, the deployment takes less than one day. If you are using the ProxySG or the on-premises solution, it will take one to two weeks depending on the policy configuration, the size of the organization, and what kinds of policies are needed. The number of staff you need to maintain the solution depends on the size of the organization, and how many changes occur on a daily basis. If you have one thousand employees then you need at least one employee to look after it.

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

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

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

"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."

"Its initial setup was straightforward."

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

"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."

"Technical support is pretty sharp and very responsive."

"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

"It features intuitive proxy policy deployment using a VPN."

"Proxy Solution and ADN and their integration capability with Blue Coat director are positive features."

"Proxy Solution and ADN, specifically its integration capability with Blue Coat Director to apply seamless policy across all of Blue Coat, along with intuitive proxy policy deployment using VPN and the ability to forward-chain your proxy, make it overall a good solution though growth requires automation support."

"Since the implementation of this solution, the bandwidth has decreased and the performance in terms of Internet access has increased."

"It's a great solution for high load enterprise infrastructure to protect company networks from web threats."

"The functionality of this solution is one of the best, and it is leading the market."

"We were able to monitor users' social media behavior and control certain activities to be allowed on the social media, which helped to prevent data loss and other activities that could result in a negative impact to the organization."

"Customer Service: Blue Touch support is top notch and very responsive when I opened service requests."

"Zscaler is an expensive solution, but it's worth the price."

"The policies are very intuitive and easy to configure, with very little possibility of messing things up."

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

"We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."

"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."

"The most valuable feature is bandwidth control."

"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."

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

Cons

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

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

"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."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

"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."

"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."

"It is stable, but due to growth, it can sometimes be less stable than wanted."

More iboss cons

"Blue Coat advertises the ProxySG as a WAF, but it really isn’t."

"The GUI works, but could be better."

"We cannot automate the product since the IP address can only be assigned after acquisition of the serial number."

"It lacks deployment over multiple platforms and integration with SDN architecture."

"It would be great if the product had inbuilt queuing for Quality of Service."

"They need to improve the intellectual analysis for APT vectors from web."

"There were benefits but the evolution is slow, hence wanting to move on with the product."

"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 reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."

"The interface for administration could be better. They should upgrade the management portal."

"The admin UI and documentation for Zscaler Internet Access could be more intuitive for new users, specifically during initial rollout and advanced policy design."

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

"Regarding improvements in Zscaler Internet Access, the admin console can sometimes be slow, particularly when navigating through reports or policy configuration."

"We'd like to have more plugins and integration."

Pricing and Cost Advice

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"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."

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

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

"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."

"Additional features, such as Flash Proxies, have their own licensing fees that depend on what the requirements are."

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

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

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

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

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

"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."

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.

What are the most important features of Iboss?

- AI Security and Visibility: conversation capture, shadow-AI discovery, AI DLP, and agent governance across Claude, Co-Work, ChatGPT, Gemini, and Grok, and emerging services.

- Data Security and Visibility: full SSL/TLS decryption, deep content inspection, MIP label compliance, and one-click compliance reporting.

- App Visibility and Control: signatureless CASB, dual risk scoring, in-app controls, and SSPM for major SaaS.

- Containerized Zero Trust SASE: dedicated containers, isolated SSL keys, one console, one policy engine, one data lake.

- Access fabric: ZTNA, VPN replacement, and SD-WAN under the same platform.

What benefits should users consider in reviews?

- Complete visibility over AI, data, and applications from one platform instead of separate point tools.

- Encrypted traffic is inspected by default so data decisions use content and context together.

- Shadow SaaS and new web tools appear as they are used, with enforceable controls in one console.

- Native data sovereignty through dedicated containers, in-region inspection, and per-customer SSL key custody.
