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

Ensures security for remote workers
The Cisco Web Security Appliance provides DLP to organizations. It helps prevent the unauthorized transmission of sensitive information by blocking such attempts. Additionally, it safeguards against malware attacks, particularly on websites not authorized by our company. Its role in protecting us from malware is pivotal. The organization itself handles the configuration and management of Cisco Web Security Appliance. Cisco assists in deploying and configuring the appliance and managing all associated services. Integrating the Cisco Web Security Appliance with other solutions is quite challenging. For instance, when we tried to integrate Netscape KSP, we encountered difficulties retrieving logs. Additionally, our solution failed to interact with the Web Security Appliance. Overall, the integration process remains problematic, hindering the effectiveness of our security infrastructure. We have both the cloud version and the on-premises version. For clients who require data sovereignty, we offer the on-premises version, which includes a data sovereignty tool. This allows them to enforce policies that prevent the transfer of logs to third-party data centres, ensuring compliance with their country's regulations. Overall, I rate the solution a nine out of ten.

Helps maintain a consistent posture of internet security while getting rid of VPN and hovering into zero trust
There could be a better way for the tool to categorize the traffic. For example, the tool does exceptions and everything overall. If I want to give guest access or provide access to guest users or any other internet access and if it does not go through the SSL inspection because, in our company, we can't have the root certificate on a device that we don't manage, which can be called out as an exception or an exclusion, but that doesn't provide a proper reflection of the picture of what is happening in the environment. There are granularities bringing it down. The tool I used or still have is Zscaler Cloud Connector to protect the cloud environment, which can have a bit more user-friendly installation and setup, and it would help a lot. The deployment process of Zscaler Cloud Connector needs to be more user-friendly. Improvements are required in the exception category. For example, suppose I report on a monthly basis what the breaches and traffic violating the SSL inspection area are coming from. In that case, I may find that half of them may be coming through some guest network, meaning the tool doesn't differentiate between the guest or normal networks or the corporate networks. Having options to differentiate different networks would be ideal so that it can show a true picture of things to users, as half of the things in the tool are not in our control and are not of our concern.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"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."
"It was a very easy product to install. It can be deployed very fast."
"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."
"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."
"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."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Content filtering is the most useful feature of iboss."
"Cisco Web Security Appliance has very good security benefits for any company and is easy to integrate."
"The tool has good Umbrella DNS security."
"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 solution provides good web reputation and anti-malware protection."
"The initial setup is straightforward."
"It also has high availability."
"Since working with the tool, we have not found any threats in our organization."
"It also allows you to decrypt SSL traffic, and that's a really important feature as well, which is something I also configured."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"All internet access flows through the Zscaler proxy, regardless of whether people are in office or remote. I have greater control site access and I minimize the number of compromises that we experience to almost none."
"The solution replaces multiple vendor technologies with one which makes it worth the cost."
"Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability."
"One feature that is valuable to me from an implementation point of view is that it's very easy to implement."
"It is easy to set up the solution."
"The solution's most valuable features are its reliability and availability, measured by the number of ports it offers."
 

Cons

"To scale up, a new iboss Node Blade Chassis must be purchased."
"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."
"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."
"File integrity monitoring would be very advantageous as an additional feature."
"Sometimes, obviously, there are bugs."
"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."
"Its pricing could be better."
"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"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."
"There are certain shortcomings related to the product's management capabilities, where improvements are required. The solution needs to provide better management of the category of web pages."
"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."
"The solution is not very compatible with other products."
"The solution needs to be more user-friendly and easier to navigate."
"The tool needs to provide logs. They need to improve firewall threat defense."
"If a user wants to use it for other devices like mobile or smartphones, this product isn't so reliable."
"It should have a user-based quota, per-user quota, that can be defined on the appliance."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"The solution can be improved by advancing some of the newer technologies such as the DLP feature, and adding email security."
"If they can also integrate with the multi-factor authentication to prompt users to do another, second-factor authentication, that would be ideal."
"They should enhance the audit reporting feature."
"One thing that they could improve is the ability to import rules from other platforms."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage."
"The tool should improve the predefined dictionaries."
"It also needs better integration with other applications as well. There are some restrictions."
 

Pricing and Cost Advice

"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"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."
"I know from the manager that the price is too high and that other solutions offer the same features for less."
"I rate Cisco WSA a seven out of ten since it is costly."
"The solution has a standard license."
"There is a subscription-based license needed to use this solution."
"At the time, licensing fees were paid on an annual basis."
"The pricing is too high."
"This is an expensive solution."
"Cisco Web Security Appliance is not the cheapest solution on the market, but it's well worth it."
"We have found the solution to be expensive."
"The price is competitive. It's not cheap and it's not expensive."
"The tool is moderately priced."
"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."
"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."
"The pricing is fair based on its competitive market."
"We pay around 6,500 INR per user per year, which is very expensive. I would rate Zscaler's pricing one out of five."
