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

Saves us time, has good visibility, and a single dashboard
The solution is user-friendly and provides great visibility into threats. There are easy options available for specific workflow inspections. We can also get support by going through the Microsoft documentation, which is straightforward. Microsoft Defender for Cloud Apps helps us prioritize threats across our enterprise. It covers us from a compliance perspective and protects our organization's data. Data protection is a very important aspect of any new organization, as we need to protect our data from both external attacks and insider threats. Microsoft Defender for Cloud Apps helps us monitor for abnormal activity by insiders, which is one of the most important access points for attackers today. Additionally, the different cloud apps that Defender for Cloud Apps supports provide us with much more visibility into potential threats and activities on the internet. We have integrated Microsoft Defender for Cloud Apps alerts with Sentinel. The integration is straightforward. We can find the configuration details on Microsoft's official documentation website. If we are familiar with how Microsoft products work, we will be able to follow the instructions clearly. Microsoft Defender for Cloud Apps and Sentinel work natively together to deliver coordinated detection and response across our environment. Our integrated Microsoft solutions provide comprehensive threat protection, covering most of the tactics and techniques relevant to the MITRE ATT&CK framework. Sentinel allows us to ingest data from our entire ecosystem. When implementing an SIEM solution, there are always prerequisites such as Active Directory logs, security logs, firewall logs, and DNS logs. These are important logs that need to be ingested into the environment. Sentinel has many third-party connectors available that make integrations straightforward. Microsoft provides the configuration details in the Sentinel platform. It is important to integrate all relevant log sources into the SIEM solution so that we can detect and be alerted to any type of threat factor, whether it is from an internal or external source. Integrating third-party solutions into the platform requires a separate configuration, but Microsoft provides the necessary information. However, we need to have the appropriate permissions to execute these setups. Sentinel provides a centralized dashboard that covers threat management and configuration. It gives us complete insight into what entities are accessing, as well as full details for investigation. We can see how the alerts and threats are relevant to suspicious activities, whether they are related to malicious IP addresses, suspicious ASHAs, or any other indicators of compromise. All of this relevant data can be seen in a single pane. Recently, Microsoft introduced a new investigation experience in a single pane. This means that we can now get a lot of details in a single pane, without having to go there and execute a query. There are a lot of new insights being developed in the Sentinel platform these days. It has software intelligence. They recently introduced Microsoft Defender Threat Intelligence, which covers almost all IOCs. This protects organizational assets from threats and suspicious traffic associated with IOCs. If a match is found, alerts are generated. This is a very interesting feature. Another great feature is automation and logic apps. We can create a number of operations, such as posting in a team's channel if a severe incident occurs or sending an email notification. There are many operations available, so we can automate a lot of tasks. Microsoft Defender for Cloud Apps helps us stay compliant. It has predefined mechanisms in place to prevent attacks. For example, if an external user tries to access our SharePoint folders or files, an attack will be blocked. This is why it is important to give appropriate access to guest users. Microsoft Defender for Cloud Apps has many features and benefits. It provides a number of policies that can be configured to meet the specific needs of our security team. These policies can be used to customize cloud applications so that only authorized users can access them and perform operations that benefit the organization. In terms of safety and security, Microsoft Defender for Cloud Apps is top-notch. Using the solution's automation features, we can suppress false positive alerts. We can also close alerts, lower their severity from "high" to "low" or "informational," or close them immediately with the appropriate commands. This will depend on the configuration automation rule and the perspective from which we are testing. Microsoft Defender for Cloud Apps provides a single console. We are also provided with Microsoft templates to enable workbooks instantly. Alternatively, we can build our own customized workbooks to provide better insights and improve our SOC efficiency and overall performance. Consolidating all of our security data into one dashboard has saved our security operations team a significant amount of time. From an analyst's perspective, it is now much easier to correlate events, investigate alerts, and visualize specific entities. For example, an analyst can quickly see all of the alerts associated with a particular IP address, or they can view all of the activity for a specific entity over the past 24 hours or 7 days. This level of detail and insight would not be possible if our data were siloed in multiple dashboards. The single dashboard saves our operations approximately 20 hours per week by eliminating the need to access multiple consoles and tabs. Microsoft Defender for Cloud Apps threat intelligence can help us prepare for potential threats before they happen. However, it depends on how we develop the policies for the database to block or ignore things in our environment.

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

"The solution has massively improved our security posture, giving us full visibility into what our staff does online."
"Content filtering is the most useful feature of iboss."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"It was a very easy product to install. It can be deployed very fast."
"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."
"Its initial setup was straightforward."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"iboss is easy to use despite its complexity. Multiple engineers manage it, but it's significantly more straightforward to administer than traditional VPNs and web proxies."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"The most effective features for data protection are data loss prevention (DLP) and data classification."
"The integration within the entire Defender suite is highly valuable because it allows for communication between different components and offers pretty decent correlations."
"The impact of Microsoft Defender for Cloud Apps on our organization's ability to assess and manage app related risks has been significant because we have more visibility."
"On-demand scanning is the most valuable feature. In addition, it's a fairly fluid product. It syncs back to the cloud and provides metrics. It's pretty intelligent."
"Defender helps us control which applications are being used and gain more security insight into remote and hybrid users based on user identity and log in location. You can also integrate Defender for Cloud Apps with Defender for Endpoint to extend its capabilities."
"Threat detection is its key feature, and that's why we use this tool. It gives an alert if a PC is attacked or there is any kind of anomaly, such as there is a spike in sending emails or we see an unauthorized website being accessed. So, it keeps us on our toes. We get to know that there is something wrong, and we can isolate the user and find any issues with it. So, threat detection is very robust in this tool."
"Better logging allows us to find problems and take appropriate steps to lock them out."
"The solution is scalable and stable."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"The solution has reduced cyberattacks."
"Whether you are in a hotel somewhere, or in Africa, it does not matter. You will get the Zscaler protection presence anywhere."
"Zscaler Web Security protects our users in remote locations from internet threats - even if they are not connected to our network."
"In terms of management and visibility, there is a single panel where you can configure the policies for your entire organisation worldwide."
"The initial setup is very straightforward."
"The solution is stable."
 

Cons

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."
"The dashboards for local use could be better."
"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."
"Sometimes, obviously, there are bugs."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"Their on-premise hardware's network interface is capped at one gigabit, which is sort of a problem. If you stand a filter up where all traffic flows through that, according to them, in order to go above a gigabit, you have to have multiple devices, which in today's IT seems a little bit silly. They could easily put in an SFP port into their device that could accommodate 10 gigs or at least offer a box."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"File integrity monitoring would be very advantageous as an additional feature."
"The response time could be better. It will be helpful if the alerts are even more proactive and we can see more data. Currently, the data is a little bit weak. It is not complete. I can't just see it and completely know which user or which device it is. It takes some effort and time on my part to investigate and isolate a user. It would be great if it is more user-friendly or easy for people to understand."
"The technical support team has room for improvement."
"Currently, reporting is not very straightforward and it needs to be enhanced. Specific reports are not included and you need to run a query, drill down, and then export it and share it. I would love to have reports with more fine-tuning or granularity, and more predefined reports."
"An area of Microsoft Defender for Cloud Apps that needs to be improved or enhanced is the reporting function. In the beginning, there was a good reporting function which gave us a sort of monthly overview report. But that has gone away."
"The interface needs to be more user-friendly."
"I would prefer to have filtering options incorporated within the policies, enabling the solution to perform tasks beyond mere blocking or allowing."
"I would like to see them include more features in the older licenses. There are some features that are not available, such as preventing or analyzing cloud attacks."
"It doesn't actually decrease the time to respond. This has been an issue with Microsoft recently. Sometimes, there is a delay when it comes to getting an alert policy email... Sometimes it takes two or three hours for that email to be sent."
"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."
"It also needs better integration with other applications as well. There are some restrictions."
"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."
"It needs better integration with other applications. It takes a fair amount of regular activity to apply the by-passes because it is very strict in its restrictions and frequently you have to go in and open things up to allow the workforce to work."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
"The OS capabilities and WSL support could be improved."
"The tool should improve the predefined dictionaries."
"The response time and engagement model for technical support could be improved to handle complex outages more efficiently."
 

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 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."
"It is expensive compared to one of its competitors."
"It has pretty good pricing."
"We are an MST and we do not pay for the solution. However, the price of the solution could be better."
"Where we are right now, this is an acceptable pricing. I would like to see more transparency given to the end user. The end user given to us is via the cloud service provider. There are different programs and license models. Some include this, and some include that. It is all over the place. There can be a little more consistency or simplification in the pricing so that your parts list is not ten pages long, and you are not trying to determine, "If I have an E3, does this cover that?", or "Do I need to pay separately for the license?" Simplification would probably be better."
"This product is not expensive."
"Microsoft offers bundle discounts and a pay-as-you-go option."
"The price could be better and should be reconsidered."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
"We have an educational licensing agreement. It's a customer agreement for multiple years."
"The tool is moderately priced."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"It is costlier than other solutions."
"Price-wise, the tool is reasonable compared to the other products in the market but it is not a very low-priced tool. The solution does provide value for money."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
