Cloud gateway has strengthened remote web security and now needs better Mac and ISP support

The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

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.

"From a corporate perspective, I understand that it's important to keep the company data safe."

"The security aspect of the solution, particularly the malware behind it, is excellent."

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

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

"Technical support is pretty sharp and very responsive."

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

"Its initial setup was straightforward."

More iboss pros

"The primary advantage of Cisco Umbrella is its ability to safeguard our users no matter where they are working from - whether it's in the office or remotely, as per the new work model that has emerged globally. This integrated security solution has simplified our lives by combining all the necessary security measures in one product. Additionally, deploying the product is all it takes to protect all our users."

"Application performance has greatly improved and there are less operational issues. Productivity has been going up because we have less operational issues. Also, we have happy customers."

"I think recently with many people working from home, Cisco Umbrella has been very useful. For example, we can manage the device and the network when the employee is not working on the local host. Cisco Umbrella is very valuable for this kind of infrastructure."

"Using this solution has meant that we've needed to make fewer firewall changes."

"It is a good cloud-based solution for DNS security."

"The initial setup is very easy and takes only a few minutes."

"It provides centralized, device-agnostic management of the Internet experience."

"As far as the IT infrastructure team goes, we're all happy with the product; it definitely takes a lot of load off of our plate and it's been functioning very efficiently and effectively, doing everything we need it to do."

More Cisco Umbrella pros

"The best thing about Zscaler Internet Access is the website filtering. In the UAE it's quite an important feature because most of the malware comes through the SQL injection and through downloads from websites. Zscaler helps protect against that."

"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."

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

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

"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."

"We enjoy all of the proxy capabilities and the capability to integrate into the SIEM/SOC solution."

"The most valuable features of Zscaler Internet Access are it's on the cloud, high network performance, and the interception of users is very easy."

More Zscaler Internet Access pros

Cons

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."

"The dashboards for local use could be better."

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

"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."

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

"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."

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

More iboss cons

"In the next release, I would like to see the integration of VDI NSX with Cisco Umbrella."

"In terms of what can be improved, it should have more integrations with multiple end user OEMs."

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

"The design of the screens could be improved. Sometimes you're trying to look for information, for what you think is critical that should be on that first screen of the dashboard so that you can quickly take screenshots to have people help out, but you have to hop between screens to find little pieces of evidence."

"We would like them to add more features to Cisco Umbrella."

"If the virtual appliances could also gather traffic bandwidth reports, that would be great."

"Their support should be improved. It is necessary that the support is efficient. It is not really easy to get a resolution for an issue from Cisco support. They should be faster and more efficient."

"The detection of wireless attacks or targeted attacks reports many false rates. This is an area that needs some improvement."

More Cisco Umbrella cons

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

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

"The current reports can, therefore, be somewhat improved and simplified."

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

"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."

"With the pricing structure that they currently have, it is only for big customers."

"Sometimes it's not easy to use during large deployments of workstations."

"The admin UI and documentation for Zscaler Internet Access could be more intuitive for new users, specifically during initial rollout and advanced policy design."

More Zscaler Internet Access cons

Pricing and Cost Advice

"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."

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

"In the region I'm from, that of EMAR, Europe, the Middle East, Eastern Asia and Africa, our organizations do not have many liquid cash assets, so the price could be better."

"I think Cisco Umbrella is priced well. We have a mix of customers with different verticals such as education. We have clients in the commercial space as well. Umbrella is at a good price point for all of our customers."

"Its value exceeds its pricing."

"You can request an evaluation license."

"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."

"The price depends on the use case, and it's a bit linear. But it depends on the customer's strategy and how Cisco plans to optimize the costs."

"The price is quite good."

"I rate the tool's pricing a five out of ten."

More Cisco Umbrella pricing and cost advice

"We have found the solution to be expensive."

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

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

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

"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."

"The pricing for Zscaler Internet Access could be made cheaper."

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