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.

Effective threat protection with room for cost and usability improvements

There are some drawbacks that I would mention. To be frank, enterprises always look for cost benefits, so Kaspersky could implement some price benefits. Additionally, regarding know-how, if I am an experienced person it's fine, but when someone novice is working with it, they need information about why certain actions are required. Security is a field that is very vast, and implications are not known to everyone. In future updates, a quick walk-through and know-how features would be beneficial, such as information text at relevant places. This will increase usability. Feature-wise, an impact analysis would be a really good addition.

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

"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."

"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."

"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."

"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 console is cloud-based, which is something I really appreciate."

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

"Our primary use case for this product is DLP,"

More iboss pros

"I would recommend it to others as it's easy to use."

"The password thing is very good, and the overall URL protection."

"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."

"The most valuable features of the solution are the antivirus and child protection features."

"The most valuable aspect for me is the user-friendly interface."

"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."

"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."

"SSL inspection is a valuable feature."

"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."

"The most valuable feature of Zscaler Internet Access is that it is a consolidated solution, it comes with many features, such as DLP."

"There is no lag in service when accessing the internet."

"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."

"The security is excellent."

"The solution is stable and reliable."

"Stability-wise, I rate the solution a nine and a half out of ten...The setup phase was easy."

More Zscaler Internet Access pros

Cons

"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."

"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."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"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."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

"Sometimes the agent stops working in iboss, and we have to reinstall the agent."

"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."

"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."

More iboss cons

"The customer support of the product is an area with shortcomings where improvements are required."

"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."

"There is room for improvement in terms of the pricing."

"When I do a configuration, I do not know what implication it will have downstream."

"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."

"I believe the absence of a procedure is the main issue."

"In different locations, they're priced differently, but that's mainly marketing rather than the product features."

"When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. "

"In every cloud service in the world, you have multiple upstream internet providers to create diversity so that if one of your providers fails, your network just continues. In South Africa, there is only one upstream provider, and that's not right. That that's a problem."

"They should enhance the audit reporting feature."

"We'd like to have more plugins and integration."

"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."

"Zscaler Internet Access can improve by adding traffic filtering based on the DNS."

"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."

"I don't know whether it's Zscaler or not, however, sometimes I can't access my time management. I need to wait and try again a few hours later. Typically, if I let some time pass, I can access it again."

Pricing and Cost Advice

"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."

"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."

"It is expensive."

"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."

"I am okay with the pricing."

"I would rate the pricing a seven out of ten, with ten being very expensive and one being cheap. It's neither too cheap nor too expensive."

"Personal computer licenses can be expensive if you were to scale the solution extensively. However, large companies will most likely use Endpoint solutions and not this one."

"I rate the product's price an eight on a scale of one to ten, where one is very cheap, and ten is very expensive."

"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."

"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."

"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."

"It is a few pounds per user per month."

"It is quite expensive. It does its job, but it is quite expensive for what we need."

"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."

"The pricing is fair based on its competitive market."

"The tool is moderately priced."

Reviews from Real Users

Below are some reviews and helpful feedback written by Zscaler Internet Access users.

A Service Manager at a construction company says, "There are a bunch of different capabilities that are valuable within the platform. We use quite a lot of them, but not everything. The ones that are most important to us are the URL Filtering and the application control. For our needs, the cloud-native proxy architecture is a very good solution. 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."

Owen N., Security Architect at Claro Enterprise Solutions, explains that the solution’s most valuable features include “The integration of the gateway that inspects all ports and protocols. So, there is threat prevention; The cloud sandbox; VNS security; Access control that will protect URL filtering and the cloud firewall; Data protection that will protect your gateway, like your CASB or your cloud DLP; The capabilities of this will point your traffic to Zscaler Cloud.”

An Architecture Senior Manager at an insurance company mentions, "The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go." He also adds, “The solution provides quick access to cloud services, securing our data and allowing us to inspect all our traffic.”
