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.

I would say the solution is stable. We've deployed it here for one year, and for the moment, we've had no issues
I would rate the product as seven out of 10. The product needs maintenance only if something is wrong with the configuration. If so, we are always available to reconfigure or make some adjustments, and the app system numbers are very available. Anytime we need them, they're there for us. The last time I called the engineer in charge of the product, he told me everything was fine apart from the setup. They want to add more ports about a dedicated service that he cannot do for us. I asked him to take a snapshot and send it to me so I can forward it to the system group. The solution can be deployed in companies of any size. One thing I would recommend to anyone contemplating implementing the product would be, don't be put off because Clearswift Secure Web Gateway is not at the top on Gartner. That does not mean it's not a good solution. I think all the solutions are equal. It all depends on how you deploy the solution and where you put it.

Helpful support, and useful dashboards
They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.

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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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 easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."
"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."
"Content filtering is the most useful feature of iboss."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"Deploying iboss leads to good return on investment, estimated around 70% to 80%."
"With the Clearswift Secure Web Gateway, we have three antivirus engines searching the cloud web for any heuristics, malware, and viruses that may be contained on a URL or in a document attached to your emails or your traffic."
"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"The sanitization is very good."
 

Cons

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."
"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."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"I appreciate that iboss's single pane of glass console gives centralized visibility into web traffic, user activity, security policies, and alerts from one dashboard, allowing us to quickly investigate incidents and monitor policy violations without switching between multiple tools, improving operational efficiency; however, the dashboard customization and reporting could be more flexible."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"I think iboss could be improved by making reporting and dashboard customization more flexible, and simplifying troubleshooting policy issues."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"if we could add a firewall policy to this process, it would be better."
"Most of our clients want to use a web proxy integrated with other functionalities, like reverse proxies, and if we could add a firewall policy to this process, it would be better."
"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."
"The DLP should be upgraded and has room for improvement."
"Although the number of AV engines is good, it could be better."
 

Pricing and Cost Advice

"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"It is expensive compared to one of its competitors."
"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"The overall pricing for iboss is very competitive and transparent."
Information not available
"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
