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

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

"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."

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

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

"Content filtering is the most useful feature of iboss."

"This product is solid, fairly easy to use, and reliable."

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

More iboss pros

"It offers good visibility for the Administrator. The administrator has full visibility of what is blocked or has the knowledge of where users go when they are surfing the internet."

"It will protect, give you more robustness, and faster responses, compared to any firewalls or any of the proxy web servers."

"It blocks malicious DNS queries daily which is very beneficial."

"My overall rating for Cisco Umbrella is ten out of ten."

"Meraki features and cloud-based functionality are advanced and easy to manage centrally."

"Helps block personal email accounts."

"Umbrella has been a godsend for that."

"It has the ability to quickly block new threats."

More Cisco Umbrella pros

"I like the granularity of the control of all the traffic, including SSL inspection. I also like the fact that the user interface is intuitive. The latencies with Zscaler are minimal compared to those of any other competitor. Other competitors do not really have the global scale that Zscaler has and cannot promise low latencies."

"Zscaler covers all the features needed to replace a VPN or proxy solution; they are good, and they've been on the market for 15 years now, so they are mature enough."

"For our needs, the cloud-native proxy architecture is a very good solution. We are moving away from on-prem appliances and moving more toward cloud-based solutions. Zscaler is a good fit for our strategy. 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."

"The most valuable features of Zscaler Internet Access include its capacity to scale, the security implementation capabilities, the ability to integrate public IPs related to clients so traffic presents on the internet as a client, and the facility to interoperate with SSEs while maintaining the same security mechanisms from on-premises to cloud environments."

"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."

"Zscaler Internet Access is very scalable, and requests for scalable solutions are met quickly."

"Having a centralized firewall that protects the whole topography is quite awesome when you also have users that are not on the plan because it actually improves visibility of those users."

"The solution is scalable and stable."

More Zscaler Internet Access pros

Cons

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

"One thing I would like to see differently with their Zero Trust platform is that some of the AI aspects related to high-risk activities have more false positives."

"Sometimes when you call in support, you get someone who is just following a sheet. It feels like a runaround. You feel that you are running into that support wall."

"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 have heard they are doing DDoS filtering, but I am not certain if they are implementing it correctly."

"File integrity monitoring would be very advantageous as an additional feature."

"Our iboss subscription access should be more secure with an OTP or VPN etc. It is easy to gain access if, for example, hackers obtain my username and password."

"The dashboards for local use could be better."

More iboss cons

"Security, overall, can always be improved."

"Lower costs including licensing, support, and renewals would be beneficial."

"There are a couple of interface issues. I know that they say that there are feature enhancements that are noted. For example, we've got the Cisco Meraki security appliances, and there, we geofence our company to where we're allowed to send and receive traffic. So, in our case, by default, we only allow traffic to six different countries, which allows us to effectively prevent traffic for the majority of bad players in the world, but they don't give you an easy way to do that in Cisco Umbrella. With Cisco Meraki, I can specify or pick the countries. I can say that I want to only allow traffic from these six countries, and I'm done. With Cisco Umbrella, I have to rely on the fact that they're going to prevent traffic to other countries. They're going to decide if it's good or bad."

"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."

"The product has been rejected by business due to the pricing; no ROI as such."

"I would like to have more applications being recorded."

"While the way the solution works with the functions is fantastic, updates or the ability to secure the vault while offline for cloud-based services should be addressed."

"The only thing I can think of is that I'd like to see a little more flexibility in policy creation. The way that policy is currently structured is like a "first hit succeeds" kind of policy. It would be nice if it were more hierarchical."

More Cisco Umbrella cons

"The tool should improve the predefined dictionaries."

"The price of the solution could be improved."

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

"Every client decided to purchase professional services because deploying Zscaler Internet Access is too complex."

"Zscaler Internet Access can improve by having more option for filtering policy which is currently only ip based (location policy)."

"Zscaler should provide adjacent services, which would be complementary to their current offering that could be more pragmatic for a customer."

"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."

"The reporting functionality could be a bit easier to use. There is a reporting function, but it's quite hard to do any good reporting, from a user-management perspective. For example, if a department manager wants to know how his department is using the web, there is a way to get the data, but it's quite cumbersome to get it and show it well. And that's true for comparing between departments."

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."

"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."

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

"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."

"The pricing is fair."

"Pricing depends on the automation requirements of the organization."

"You get what you pay for if you break the solution up into tiers."

"Pricing and licensing of Cisco Umbrella is a bit confusing because you have to separate the DNS solution and the full-feature solution. Cisco in Portugal helped us understand which one was the right one for us."

"Its value exceeds its pricing."

"It was a little bit expensive on a per seat basis, but the company I was running was only a midsize Australian company, and it was a reasonable budget per computer for that system. It started off being a free product, and then Cisco bought it, and it went to a reasonable price. I was using Cisco AMP as well. So, my per computer cost was reasonably high, but for a small company, it was within an acceptable level."

"The solution’s pricing is reasonable."

"The pricing is great and very competitive with the rest of the market."

More Cisco Umbrella pricing and cost advice

"We have found the solution to be expensive."

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

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

"The tool is moderately priced."

"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."

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

"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."

"It is costlier than other solutions."

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."
