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

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

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

"Its initial setup was straightforward."

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

"We were impressed by the solution's mental health function, which can detect if someone needs help. It scans what users are browsing and flags warning signs so we can check to see if they are okay. We've had to use it a couple of times."

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

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

"From a corporate perspective, I understand that it's important to keep the company data safe."

More iboss pros

"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."

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

"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."

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

"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."

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

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

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

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

"The most valuable features of Zscaler Internet Access are it's on the cloud, high network performance, and the interception of users is very easy."

"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."

"Overall, it's a good solution; we had very few issues during implementation, technical support is quite helpful and responsive once you get a hold of them, it has private access and has a lot of features inbuilt including DLP and CASB, and the solution is scalable and stable."

"The solution’s customer service is good."

"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."

"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."

More Zscaler Internet Access pros

Cons

"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."

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

"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."

"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."

"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."

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

More iboss cons

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

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

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

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

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

"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."

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

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

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

"The DLP part is quite crucial for this particular region."

"The solution is expensive. They recently revised the pricing and packaging. Some of our existing customers have been asking for alternate solutions for a lower price."

"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."

"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."

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

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."

"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."

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

"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."

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

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

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

"We have found the solution to be expensive."

"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."

"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."

"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."

"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."

"Our monthly fee is around R3000."
