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.

Offers good reliability and availability to users
Sometimes, cost is one component that customers complain about, especially if they compare it with some of its competitors. Zscaler's pricing seems to be a bit on the higher side. I think the pricing model is also something that the tool can probably look into to optimize or improve for the customer so that it can be a competitive tool commercially. The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas.

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."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"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 solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Technical support is pretty sharp and very responsive."
"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."
"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."
"I would recommend this solution to others."
"The product is stable."
"What we liked best about it was the ability to apply policy to either a user ID or an IP-based network."
"The most valuable feature of Cisco Web Security Appliance is the provided anti-malware functionality and URL categorization. I can block access to malicious websites. 99 percent of the cases are related to a malicious website. If I cannot browse those malicious websites, then we are 99 percent protected."
"Great for assisting with connections to networks or apps."
"The most valuable features of the solution are the functions of proxy for the users who use the internet and the security it offers against the not-so-secure web pages."
"The best feature of Cisco Web Security Appliance is its policy framing. It also has a good UI and it can handle traffic well. Cisco Web Security Appliance is a good product."
"Cisco regularly upgrades features for the customer's security requirements."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"Zscaler excels in security protection and the cloud is always up-to-date. It does not matter if you are a small or big organisation, you will receive the same security quality."
"The most valuable features I found in Zscaler Internet Access are the restriction of users for a particular URL, the security feature related to stopping DDoS, and the VPN."
"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 security is excellent."
"Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."
"The protection is most valuable."
 

Cons

"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."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"File integrity monitoring would be very advantageous as an additional feature."
"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"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."
"Its pricing could be better."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"The tool needs to provide logs. They need to improve firewall threat defense."
"The reporting needs improvement."
"The one thing I don't like about Cisco is that they are very much fragmented in terms of providing the complete solution. They keep on breaking their different feature sets into different boxes."
"The solution could improve the graphical user interface. It is not up to the regular standard of what we would expect from Cisco. Additionally, they need to improve the categorization when blocking in the settings. The CLI could have a better view than the graphical user interface but I did not investigate further."
"As Cisco Web Security Appliance is eight years old, though it's simple to access its UI, the UI needs a little bit of updating. If it could be more interactive similar to the latest gen solutions, that would improve the product. Adding a few more integrations would also make Cisco Web Security Appliance better."
"The solution is priced high."
"The support for this solution could be improved. We have experienced issues with their SMARTnet support system."
"The tool needs to provide logs. They need to improve firewall threat defense."
"The solution is expensive. They recently revised the pricing and packaging. Some of our existing customers have been asking for alternate solutions for a lower price."
"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."
"Zscaler Internet Access's troubleshooting is very limited, and their textbook logs need to be more informative."
"In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution."
"In terms of user experience, it could be better."
"The solution's pricing is on the higher side. It would be better if it could be lower."
"The tool should improve the predefined dictionaries."
"There are a few features that are not compatible with the Azure cloud."
 

Pricing and Cost Advice

"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 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."
"It is probably in line with other solutions, but I do not deal with the financial side."
"I rate Cisco WSA a seven out of ten since it is costly."
"The pricing is too high."
"I rate the product price a ten on a scale of one to ten, where one is low price and ten is high price."
"I rate Cisco WSA a seven out of ten since it is costly."
"I know from the manager that the price is too high and that other solutions offer the same features for less."
"This is an expensive solution."
"Cisco Web Security Appliance is not the cheapest solution on the market, but it's well worth it."
"The tool's licensing is yearly."
"The pricing is an issue. It is expensive compared to other firewalls on the market."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"It is costlier than other solutions."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
"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."
"If we need any extra features, the price will increase."
"We have found the solution to be expensive."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
