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 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."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"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."
"As I mentioned, the return on investment is significant, as it saved our office locations' bandwidth because when you are working remotely at home, your internet traffic routes directly to iboss and will not go to your office building, saving bandwidth bottlenecks and ensuring that issues with our building internet circuits will not impact your internet connectivity because you are directly going to the iboss data center."
"iboss is definitely very good in terms of service."
"The security aspect of the solution, particularly the malware behind it, is excellent."
"It was a very easy product to install. It can be deployed very fast."
"The solution is stable."
"Trend Micro Web Security is a great product; it is compatible with anything on the market in my opinion, very competitive and very flexible, and for at least 20 years it has always been top of the line."
"It has just about everything we need at a good value."
"The product's installation phase was easy."
"Trend Micro Web Security is used to protect the organizations from shoulder surfing and it also does certain classifications to provide protection not only from a security point of view, but also from a GRC (governance, risk, and compliance) point of view."
"The real-time threat detection capability of Trend Micro Web Security has had a positive impact on our security."
"The solution's technical support team is responsive."
"It prevents phishing attacks, ransomware attacks, and other threats that can compromise data."
"The solution’s customer service is good."
"Because it is well integrated and mature, it's faster, cheaper, and better for the company."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"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 enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"We have seen an ROI; this is a well published product, and you get value for your money."
"Zscaler has helped to reduce the time we spend managing security policies, significantly lowered the number of FTEs needed to manage the environment, and has definitely helped reduce the number of infected devices in our organization by proactively preventing attacks."
 

Cons

"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."
"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 endpoint-type solution is an area that needs some improvement."
"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."
"The dashboards for local use could be better."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"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."
"I would rate the technical support by Trend Micro a three. The response time is poor."
"The cons include it not being implemented in the mid-enterprise segment. For these organizations, it is an additional expense."
"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."
"The stability of the product is an area of concern where improvements are required."
"The costs are a bit high in terms of licensing."
"I would like to see better scalability and better performance."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"The solution is quite expensive. It's around double what others are offering."
"I would like to see the ability to choose a pool of IPs for my company, set up rules based on them, and know that those IPs are not used by other companies."
"The current reports can, therefore, be somewhat improved and simplified."
"The price of the solution could be improved."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage."
"One thing that they could improve is the ability to import rules from other platforms."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
 

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 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 license is yearly and user based."
"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."
"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."
"The solution is expensive in terms of deployment."
"I don't remember the exact pricing, but I think that it is approximately $10.00 per user."
"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."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"We have found the solution to be expensive."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"It is costlier than other solutions."
"The tool is moderately priced."
"The pricing for Zscaler Internet Access could be made cheaper."
"Zscaler is transparent about its pricing model."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
