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.

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

"Technical support is pretty sharp and very responsive."
"The console is cloud-based, which is something I really appreciate."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"From a corporate perspective, I understand that it's important to keep the company data safe."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"Its initial setup was straightforward."
"We have found this product to be very cost effective."
"Currently, many applications are hosted on the web. They are hosted in multiple clouds and tenants. Organizations with different geolocations and users require a very secure WAF solution. For enterprise companies, it is essential to secure their networks and applications."
"The security of Trend Micro Web Security is good."
"We find the advanced license for the DLP to be particularly useful with this product."
"The real-time threat detection capability of Trend Micro Web Security has had a positive impact on our security."
"Trend Micro Web Security is used for web filtering and protects the environment from web threats and malicious sites."
"It prevents phishing attacks, ransomware attacks, and other threats that can compromise data."
"The EDR feature is very good; it's one of the better features of security and can protect a large percentage of the company."
"From the top to bottom, Zscaler Internet Access is a great security product that protects my end users and remote users in the cloud."
"It securely transfers internet connectivity seamlessly, without any problems or issues."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."
"We don't have to buy equipment to use it. And when our engineers set it up on our side, we just configured a few settings and we were in."
"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."
"Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality."
"The solution is stable and reliable."
 

Cons

"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"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."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"The reporting feature needs improvement."
"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."
"I would rate the technical support by Trend Micro a three. The response time is poor."
"The ease of use depends on the blacklisting of the sites. Some of the authorized sites have been blacklisted, which requires a request to unblock the site."
"The costs are a bit high in terms of licensing."
"The interface could be improved; we need it to be more user-friendly."
"The system should generate reports when an attack has been stopped, contained, or removed."
"The product should be more secure and stable. It is also not flexible."
"They could improve the platform's ability to control normal traffic and prevent attacks like SQL injection and cross-site scripting."
"The solution's scalability could be better."
"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."
"I would like to see more training and video documentation."
"The price of the solution could be improved."
"There are a few features that are not compatible with the Azure cloud."
"The solution's pricing is on the higher side. It would be better if it could be lower."
"Do not expect to pay for the service and start using it, like Gmail. Zscaler requires a proper implementation to be done to make it successful."
"They could provide more time for the onboarding the training of an IT person."
"Sometimes, support isn't available."
 

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."
"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."
"I rate the product price a three on a scale of one to ten, where one is cheap, and ten is expensive."
"The solution is expensive in terms of deployment."
"We pay for the license on an annual basis."
"We have found this product to be very cost effective. The endpoint product costs roughly $20, and when purchasing the endpoint product, there are multiple other features included."
"I don't remember the exact pricing, but I think that it is approximately $10.00 per user."
"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 rate the product's price a five on a scale of one to ten, where one is low price and ten is high price."
"The license is yearly and user based."
"If we need any extra features, the price will increase."
"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."
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"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."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"Our monthly fee is around R3000."
