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

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Technical support is pretty sharp and very responsive."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"Its initial setup was straightforward."
"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."
"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."
"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 is stable, but due to growth, it can sometimes be less stable than wanted."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"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."
"File integrity monitoring would be very advantageous as an additional feature."
"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."
"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."
"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."
"Although the number of AV engines is good, it could 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."
 

Pricing and Cost Advice

"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."
"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."
"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."
Information not available
"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
