It's easy to roll out, and their understanding of our business made it seamless

One aspect we value about iboss is its simplicity. Their customer service is brilliant, and they are super responsive and knowledgeable. It's easy to roll out, and their understanding of our business made it seamless. 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 user interface is highly intuitive. Our IT team picked it up with minimal training. It's arranged so that it's easy to find where things are. Another advantage is the single pane of glass console, which gives you visibility into what's happening. We're not fully there yet because we haven't implemented zero trust, but we're excited about the possibilities from the demos we've seen. We launched a POC of iboss' ChatGPT Risk Protection feature two weeks ago. AI is a great tool, but you need to be careful what you put into it. My biggest fear is employees inputting sensitive corporate information or customer PII data into one of these chatbots. I was impressed by our trial of the feature. It's exactly what we wanted. Now, when a user goes to ChatGPT, there's a banner warning them not to share information, and we can block conversations containing customer data like bank details and email addresses. I don't want to stop people from using it, but we need visibility. We've only tried it on a test group of 15 people. You can configure it to look for specific keywords or integrate it with your DLP policy if you have that configured

Schedule the timing for the kids to get onto the internet and easy to use

In different locations, they're priced differently, but that's mainly marketing rather than the product features. I managed to get a cheaper one, so I'm fine with that. Maybe they have too many packages. It's very difficult to differentiate among their own packages. They should have guidance on how the customer would decide. Kaspersky do has some information, but to me, it's not explanatory. Moreover, people are getting internet smart homes and all that. So total security that would cover all those would be good. We have all the connected devices right now. I'm not sure how they're gonna do it, but having a way to help me scan and expose vulnerabilities on those devices would be great. Right now, it protects the PCs, not the IP cameras that we use. And all those things in your home are connected. I don't see that. Maybe I'm not aware if they have any offering, but they probably should think about it. So, I would like to have total coverage for the individual household that would include all of the connected devices.

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

"iboss is among the few products providing inline filtering where no application is needed on the device."

"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."

"From a use-case scenario, what I like the most is the plug-in. I like the fact that we can do the filtering of these devices offsite independent of the network they are connected to, and we do not have to have traffic coming back inside our network."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"iboss has significantly lowered the number of security incidents. It is crazy how much it blocks and how much it is aware of the outside danger."

"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."

"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."

More iboss pros

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

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

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

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

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

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

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

"The URL filtering has been the most valuable feature."

"Zscaler offers a centralized DLP solution for web, endpoint, and email."

"Overall, we're very happy with our product."

"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."

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

"The solution replaces multiple vendor technologies with one which makes it worth the cost."

"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."

"The product's initial setup phase is a bit easy, as one doesn't need high technical expertise."

More Zscaler Internet Access pros

Cons

"Its pricing could be better."

"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."

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

"Sometimes, obviously, there are bugs."

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

"To scale up, a new iboss Node Blade Chassis must be purchased."

"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 solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."

More iboss cons

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

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

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

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

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

"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."

"There are many functionalities in Zscaler Internet Access that need improvements, such as an advanced firewall and logging capabilities to track calls."

"There are a few features that are not compatible with the Azure cloud."

"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."

"Zscaler Internet Access could improve by adding a VPN feature."

"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."

"What could be improved in Zscaler Internet Access is its price. It could be cheaper."

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

"The admin console needs improvement as it loads slowly and sometimes takes two to five minutes to open."

More Zscaler Internet Access cons

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."

"It is expensive compared to one of its competitors."

"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."

"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."

"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."

"It is expensive."

"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."

"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."

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

"The price is competitive. It's not cheap and it's not expensive."

"The price of Zscaler Internet Access should improve, it is expensive."

"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."

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

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

"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 pricing is an issue. It is expensive compared to other firewalls on the market."

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

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.”
