Enhances web security with a single pane of glass and flexible deployment
I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

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

"iboss is definitely very good in terms of service."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"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 console is cloud-based, which is something I really appreciate."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"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."
"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 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."
"It's secure and useful from an administrative point of view, with controllable login monitoring and so on."
"The product's installation phase was easy."
"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."
"We find the advanced license for the DLP to be particularly useful with this product."
"I feel that it is a user-friendly product that provides quick response to users."
"It's secure and useful from an administrative point of view, with controllable login monitoring and so on."
"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."
"Overall, we're very happy with our product."
"Zscaler offers the best service since you are protected wherever you are."
"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."
"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."
"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."
"Zscaler covers all the features needed to replace a VPN or proxy solution. They are good. They've been on the market for 15 years now, so they are mature enough."
"SSL inspection is a valuable feature."
"It is easy to set up the solution."
 

Cons

"SSL decryption: We had issues with learners using apps instead of using web browsers."
"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"It is stable, but due to growth, it can sometimes be less stable than wanted."
"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."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"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."
"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"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 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."
"What could help Trend Micro Web Security in terms of improvement is the addition of a DDoS protection feature."
"The stability of the product is an area of concern where improvements are required."
"There are multiple ways Web Security could improve, such as usability and web access to several programming modes."
"The system should generate reports when an attack has been stopped, contained, or removed."
"The licensing is paid annually. It is a little bit expensive when you compare it to the competition."
"Zscaler is one solution. It's a good solution, but it doesn't do everything."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"The price of the solution could be improved."
"Zscaler Internet Access can improve by having more option for filtering policy which is currently only ip based (location policy)."
"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."
"The interface for administration could be better. They should upgrade the management portal."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"The tool should improve the predefined dictionaries."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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 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."
"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 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."
"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."
"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."
"The license is yearly and user based."
"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."
"I don't remember the exact pricing, but I think that it is approximately $10.00 per user."
"Licenses are available on a per-host basis. Some features like sandboxing require an additional fee, but most standard features are included in the license."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The price of Zscaler Internet Access should improve, it is expensive."
"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).​"
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
"If we need any extra features, the price will increase."
"We have found the solution to be expensive."
