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

Advanced protection features offer robust security while integration process presents challenges
With the WebAssign integration, it is not easy when I am integrating policies within the company, especially with NAND and wireless policies. The challenge arises when traffic is blocked from either wireless or wired connections. Although implementing it as a standalone is quicker, integrating BYOD with Cisco I and FTB can be tiring. Once it is done correctly, the functionality and reports become valuable, although the implementation part can still be challenging.

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

"Valuable features: Within the filter: Controls (Web categories, applications, and Allow/Block list) and Network (local Subnets). Within the reporter: Logs (Event Log) and Reports."
"I would definitely recommend iboss for web filtering purposes to other organizations or individuals."
"iboss is among the few products providing inline filtering where no application is needed on the device. It operates on the network side and is not device-based. This feature was one of the main reasons why we stayed with them for so long."
"Content filtering is the most useful feature of iboss."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"Its initial setup was straightforward."
"The solution provides good web reputation and anti-malware protection."
"Great for assisting with connections to networks or apps."
"I would recommend this solution to others."
"Cisco is the best in giving technical support. There is no doubt about that."
"The solution offers content filtering and micro-content controls, such as regulating the types of images and their resolution."
"The features I like most are the DLP functionality for web security and malware protection."
"Since working with the tool, we have not found any threats in our organization."
"Cisco regularly upgrades features for the customer's security requirements."
"One on the main benefits is protection all time from anywhere."
"The most valuable feature of the solution is SWG traffic."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"The scanning feature is impressive, because they do not introduce a big latency to the traffic."
"Zscaler Internet Access protects using data loss prevention. If you have a CASB exposing your cloud out into the network, then Zscaler Internet Access will go ahead and control that unknown cloud application in the CASB, protecting it. There is also data detection with exact data match. This improves the data coming into your cloud so you are protecting it."
"Zscaler Internet Access's roaming user feature is most valuable and is much better compared to other secure web gateways."
"The security is excellent."
 

Cons

"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"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."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"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."
"File integrity monitoring would be very advantageous as an additional feature."
"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."
"The transparent proxy is quite difficult to enforce on smartphones and tablets."
"Setting up Cisco Web Security Appliance is highly complex and it takes about a week. We have to connect it to the Active Directory and configure all the policies for end users. It takes a long time to configure rules for our company data like port forwarding and separating the public and local components."
"Sometimes reporting is a little bit short."
"The support for this solution could be improved. We have experienced issues with their SMARTnet support system."
"They need a better graphical interface, and they need a better ISE mechanism."
"I would like more automation."
"Technical support needs to be improved because they take a very long time and there is no communication or notification."
"It should have a user-based quota, per-user quota, that can be defined on the appliance."
"In terms of user experience, it could be better."
"The pricing is an issue. It is expensive if you have all of your users in the same location. It is expensive compared to other firewalls on the market."
"They should enhance the audit reporting feature."
"It also needs better integration with other applications as well. There are some restrictions."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"Zscaler should continue to make the user interface better. They should also improve the backup network and continue to expand it so that it can handle larger numbers of customers."
"We'd like for them to include some sort of antivirus tool."
"The tool should improve the predefined dictionaries."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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 overall pricing for iboss is very competitive and transparent."
"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."
"I rate the product price a ten on a scale of one to ten, where one is low price and ten is high price."
"At the time, licensing fees were paid on an annual basis."
"Licensing fees are based on the number of users."
"I rate Cisco WSA a seven out of ten since it is costly."
"Regarding Cisco price-wise, it is always on a bit on the higher side."
"Cisco Web Security Appliance is not the cheapest solution on the market, but it's well worth it."
"When you compare the price of this solution to the price of FortiGate, it's high."
"The licensing options begin with 100 users and this is a high threshold for smaller networks."
"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."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"The pricing for Zscaler Internet Access could be made cheaper."
"If we need any extra features, the price will increase."
"The pricing is fair based on its competitive 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).​"
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"We have found the solution to be expensive."
