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.

Ensures comprehensive protection with seamless threat logging and efficient policy management

My favorite feature of Cisco Umbrella is probably just the DNS and the fact that when a security threat happens, all of that gets logged in their Umbrella portal, and it's very easy to find who's been accessing the site and how many people have accessed it, so that we can go to them and make sure they're not compromised. The features of Cisco Umbrella benefit my company by providing less time to search for things through logs, to look for what we need. It's just one place to go, and we just search for it, and we find it really fast. The fact that there's a virtual database that has all that information is great on our portal.

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

"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."

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"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."

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

"iboss is definitely very good in terms of service."

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

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

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

More iboss pros

"The various powerful query options are the most valuable features of this product to me."

"Go for it; there is no better way to secure guest networks without any headaches."

"The weekly reportings are great, the investigation is super and the application management is equally great."

"Overall, Cisco Umbrella is pretty easy to use, pretty easy to deploy, and it does what we want it to do."

"I have found the malware protection feature valuable. It is helpful and deliverable and is able to protect my entire organization from getting compromised. It also prevents us from visiting any malicious sites which are not visible to the users."

"Cisco Umbrella is a very good product as of now as there is no competition."

"The security and access control features."

"The biggest return on investment when using Cisco Umbrella for me is the ease of use of the fact that we've deployed this with our Cisco VPN Secure Client, so every computer has the Umbrella module in it."

More Cisco Umbrella pros

"This solution helps you establish a secure connection from your laptop to the closest Zscaler point of presence, so you have protection anywhere in the world."

"The solution is stable and reliable."

"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."

"The solution is scalable, we have around 70,000 total users across various environments."

"The protection is most valuable."

"After a proper implementation, the maintenance is very low."

"The initial setup is very straightforward."

"Zscaler Internet Access integrates effectively, especially with the high-level IP services."

More Zscaler Internet Access pros

Cons

"Its pricing could be better."

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

"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."

"The endpoint-type solution is an area that needs some improvement."

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

"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 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."

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."

More iboss cons

"It would be good if the more complex versions of Umbrella are simplified so that we can offer them in a more standardized way. We, as a telco, do not operate the same as a traditional integration partner would, who can sell all its services. We try to have a standardized approach as much as we can so that we can sell the solution with as many services added to it as possible. If you look at the structure of businesses in Switzerland, 95% of them have 10 persons or less, and they do not have a security specialist. Therefore, the higher the automated and standardized features, the better it is for them."

"Actually, we recently switched over to Zscaler because it has more features and it's more scalable than Cisco Umbrella."

"Overall, I'm quite happy with Cisco products, but there could be one place where you can check what's going on. There could be one place where you get all the information about these products so that you don't need to look around. You get the status, information about what lately happened, and if there was anything on the machine in one single place."

"I would like to see DLP integration in the next release of this solution."

"The channel of support needs improvement. It is not under normal Cisco support, and I cannot simply call for support."

"If a hardware platform were provided for Umbrella, that would definitely improve the market for it. Especially when we are addressing governmental customers, they hesitate to connect to the cloud."

"They should provide more integrations and bring things together so that there is a more standard feel to their platform. We also use Cisco ISE, and it has a very different feel from Cisco Umbrella."

"The rule-making process for blocking sites or for blocking characteristics can use some simplification."

More Cisco Umbrella cons

"They block Zscaler IPs when the traffic origin is from Zscaler IPs. They've been blocked by certain government organizations so the end users are not able to visit those websites unless we ask them to unblock those IP."

"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."

"The DLP part is quite crucial for this particular region."

"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."

"Zscale is providing a proxy IP, and most government sites will block traffic from a proxy. Also, we see some performance issues on the cloud side during DC failover."

"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."

"The OS capabilities and WSL support could be improved."

"The solution is expensive. They recently revised the pricing and packaging."

More Zscaler Internet Access cons

Pricing and Cost Advice

"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 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."

"As an educational partner, we get better licensing structures. We are very happy with that. It has been very nice that Cisco has partnered with the educational sector to bring that."

"It has a reasonable price. It is certainly not as expensive as it used to be. It is in line with other offerings on the market. There are a number of different flavors of Umbrella. They could bring Umbrella SIG down a bit because its price is a little bit high for what it does, but I also understand why its price is high."

"There is a subscription cost."

"The pricing is pretty fair. It's good."

"We were using the free version, and we implemented the paid version about two months ago. I'm paying a fair price, but everything is negotiable with Cisco. One of the benefits that I got by having Cisco Umbrella is the licensing of the Cisco AnyConnect VPN client."

"In terms of licensing, we're not able to be extremely clear with the customer because it's based on their reporting. It's not based on the actual traffic. If they say they have 50 users but they have 80, we'll just buy for 50 users. That's something where we'd like to have more flexibility."

"Our licensing fees are on a yearly basis."

"I think it's worth the money."

More Cisco Umbrella pricing and cost advice

"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."

"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."

"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."

"Zscaler is transparent about its pricing model."

"If we need any extra features, the price will increase."

"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."

"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."

"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."

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.”
