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."

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

"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."

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

"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."

"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."

"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."

More iboss pros

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

"The customer experience is very good, and the product improves security posture."

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

"It has improved our organization from a security posture perspective. We feel more confident now knowing that we can block phishing attempts or any type of malware that is DNS-related. This is a very nice feature that provides peace of mind."

"I haven't found any issues related to latency or any other issue."

"We can have a full overview and a quick overview of all the DNS requests. For us, it's quite important."

"The most valuable thing is how easy it is to deploy. We did it with 9,000 users at my last job, and it took a week to get to all the endpoints. Doing that without having to physically touch all those endpoints was very simple."

"Cisco Umbrella is specifically designed for DNS protection, with features including a user-friendly console and the easiest installation, and it offers very prominent threat feeding from different Talos sources, securing multiple platforms while helping protect from malware and unsafe sites and mitigating DNS attacks to ensure secure browsing for end users."

More Cisco Umbrella pros

"Zscaler Internet Access's best feature is the granular policy controls."

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

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

"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."

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

"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."

"The scanning feature is impressive, because they do not introduce a big latency to the traffic."

"The policies are very intuitive and easy to configure, with very little possibility of messing things up."

More Zscaler Internet Access pros

Cons

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

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

"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."

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

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

"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."

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

More iboss cons

"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 main issue that we have is with the final steps or the full integration and getting rid of Zscaler. The company still has to fall back to Zscaler when something in Umbrella is not working as expected, such as when we enable SSL inspection. When something is not working 100%, the company is falling back to Zscaler."

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

"Support for multiple domains is important to us."

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

"Data reporting could be improved."

"Missing a real data leakage prevention solution."

"In my experience with Umbrella support, sometimes the response times take a bit more time than we would like... sometimes, if you go through email, it can take quite a while to get a response."

More Cisco Umbrella cons

"The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas."

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

"Cloud App’s database should be improved."

"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."

"One thing that needs to be improved is their presence in China. I'm not sure if that's a Zscaler thing or if it's a problem with all vendors in this space, but it would be nice to have better coverage in China. This concern is a common one for vendors across the board when dealing with the Chinese market."

"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."

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

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

More Zscaler Internet Access cons

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."

"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."

"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."

"We have not priced the solution recently, but they were competitive with other vendors in the past."

"There are no hidden costs with Umbrella. Everything is included in the package."

"Our licensing fees are on a yearly basis."

"The price is fair, and the licensing cost is based on the number of users. We have seen a good ROI."

"Cisco uses subscription models for the pricing and there are three subscription plans."

"We have a security Enterprise Agreement with Cisco, so the pricing is good."

"The pricing was marvelous."

"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."

"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."

More Cisco Umbrella pricing and cost advice

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

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

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

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

"Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc)."

"Zscaler is transparent about its pricing model."

"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.”
