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.

Consistent web protection has prevented incidents and supports flexible hybrid security models
I would rate Trend Micro Web Security a nine, but not because I have some issues in mind. I have only seen a bit better product. I was also a McAfee partner some time ago, when there was still McAfee. Some features definitely in McAfee were better than what I see in Trend Micro. I cannot tell what Trend Micro could learn from web security products of their competitors because this product has not existed for at least eight years now for McAfee, and I have no experience with other competitors. But relative to my experience and expertise, I should rate it a ten, but still I am a bit cautious because other products also have great features and these features are not covered 100% by Trend Micro. I cannot tell what additional features I would like to see in the next release, but when I see such a feature, it is very compelling. When you get into a new car and this car has something new and great, adaptive suspension, whatever, you just feel a nice feeling and you want this car. That is how I feel. I have not complained that something is missing from Trend Micro product, but I have seen in specific examples some great ideas in competition.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.

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."
"I would say iboss is a very good product; its scalability is very good, and it's seamless for the user."
"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."
"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"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."
"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"Threat protection solution with good stability and scalability. Installation is straightforward. Support for this product is good."
"The solution is stable."
"It's a stable solution."
"Overall, I would rate this solution a ten out of ten."
"It has just about everything we need at a good value."
"Trend Micro has a good portfolio for security solutions."
"It's secure and useful from an administrative point of view, with controllable login monitoring and so on."
"Trend Micro has a centralized mechanism where we can control and monitor all system protections. It includes detecting any wireless problems, which will be displayed on our portal. We plan to investigate the issues with those systems internally."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
"Zscaler Internet Access integrates effectively, especially with the high-level IP services."
"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."
"The policies are very intuitive and easy to configure, with very little possibility of messing things up."
"I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"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."
"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
 

Cons

"File integrity monitoring would be very advantageous as an additional feature."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"Its pricing could be better."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"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 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."
"I would like to see better scalability and better performance."
"The price of Trend Micro Web Security is the only area of concern where improvements are required. From an improvement perspective, the product should be made available to users at a cheaper rate."
"What could help Trend Micro Web Security in terms of improvement is the addition of a DDoS protection feature. It also needs to be more comprehensive to meet the needs of large-sized companies."
"The product's scalability is an area of concern where improvements are required."
"The product should be more secure and stable. It is also not flexible."
"The cons include it not being implemented in the mid-enterprise segment. For these organizations, it is an additional expense."
"There is room for improvement in the anti-malware capabilities."
"They could improve the platform's ability to control normal traffic and prevent attacks like SQL injection and cross-site scripting."
"The OS capabilities and WSL support could be improved."
"There are many functionalities in Zscaler Internet Access that need improvements, such as an advanced firewall and logging capabilities to track calls."
"Another thing that I would like to see is if Zscaler could have a separate product for direct access. I looked at a private access solution, but I understand there's a separate product that isn't integrated with this."
"The tool should improve the predefined dictionaries."
"The admin UI and documentation for Zscaler Internet Access could be more intuitive for new users, specifically during initial rollout and advanced policy design."
"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."
"The license is per user, and there's a minimum license per user per year. It's costly if you compare it to the traditional solutions like Symantec or Bluecoat."
"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."
 

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."
"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."
"It is expensive compared to one of its competitors."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The overall pricing for iboss is very competitive and transparent."
"It is probably in line with other solutions, but I do not deal with the financial side."
"The license is yearly and user based."
"We pay for the license on an annual basis."
"I rate the product price a three on a scale of one to ten, where one is cheap, and ten is expensive."
"It is pricey. Trend Micro has been in the field for 30 years, so you have to pay a premium amount for that."
"The solution is expensive in terms of deployment."
"I rate the product's price a five on a scale of one to ten, where one is low price and ten is high price."
"There's annual and monthly options for the license. When you're on the managed services option, it's monthly. They're also setting up an option via AWS where there will be a monthly option via the AWS shopfront."
"I don't remember the exact pricing, but I think that it is approximately $10.00 per user."
"The pricing is fair based on its competitive market."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"There are multiple bundles: enterprise, business, and transformation. Transformation includes all the features, but recently I've seen a few more line items that are additional costs. Overall, it's expensive."
"The price is competitive. It's not cheap and it's not expensive."
"It is costlier than other solutions."
