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.

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

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"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."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"Its initial setup was straightforward."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"Content filtering is the most useful feature of iboss."
"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."
"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"The most valuable feature is the ease of management. It's important."
"If your business requirements are relatively simple, it can get the job done."
"The product helps us with privileged identity management to control who has access to what and for how long."
"It's very easy to install and it includes the Intune portal from Microsoft where I can control all the devices from one place."
"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."
"We have become more aware of what services our users are using, how often they are using them, and what data is being sent out of the organization and to which services. So, it is really a lot about visibility and helping us make decisions based on that. It drives some of our policy decisions for adding extra security controls."
"I like the web GUI/the management interface. I also like the security of Microsoft. As compared to other manufacturers, it's less complex and easy to understand and work with."
"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 most valuable features of Zscaler Internet Access are it's on the cloud, high network performance, and the interception of users is very easy."
"The URL filtering has been the most valuable feature."
"The VPN is valuable, as the whole technology is very different from a traditional VPN."
"We use ZIA for outbound internet connectivity. The internet traffic of on-prem users will be directed to the ZIA cloud for security checks and web filtering."
"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
"The solution offers a distributed organization to master and to control all of the endpoints."
 

Cons

"Sometimes, obviously, there are bugs."
"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."
"Sometimes the agent stops working in iboss, and we have to reinstall the agent."
"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."
"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."
"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."
"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."
"Sometimes, we'll get false positive alarms. For example, when a SharePoint path has no file sharing, but there is an external user, it will trigger an alarm that the file has been shared with an external user... the alerting mechanism should be more precise when giving you an alert about what activity has been done with the file..."
"They need to improve the attack surface reduction (ASR) rules. In the latest version, you can implement ASR rules, which are quite useful, but you have to enable those because if they're not enabled, they flag false positives. In the Defender portal, it logs a block for WMI processes and PowerShell. Apparently, it's because ASR rules are not configured. So, you generally have to enable them to exclude, for example, WMI queries or PowerShell because they have a habit of blocking your security scanners. It's a bit weird that they have to be enabled to be configured, and it's not the other way around."
"The documentation could be improved as it is not updated immediately when Microsoft makes changes. Users must wait a few weeks for the changes to be reflected in the documentation."
"We are having trouble with our continuous reporting configuration and struggling with configuring the collector properly with our log parsing."
"We would like to get more information from the endpoint. I don't get enough detailed information right now on why something failed. There is not enough visibility."
"The integration with macOS operating systems needs to be better."
"They should continue integration with all other Microsoft security-related products. The integration with all the other products is still ongoing."
"Zscaler needs to add client-to-client communication. It's always client-to-server communication. The cloud and branch connectors could be improved because we're still dependent on traditional firewalls. They should eliminate this. They should also provide WAN devices should to compete with the SD-WAN solutions also."
"Technical support could be better."
"What could be improved in Zscaler Internet Access is its price. It could be cheaper."
"The main issue with Zscaler Internet Access is proxy IP detection, which sometimes makes sites inaccessible."
"Currently, the solution's interface is not that user-friendly."
"One thing that they could improve is the ability to import rules from other platforms."
"​When you have appliances, SSL inspection is always a headache due to poor performance and/or lack of ciphers implemented. ​"
"They could provide more time for the onboarding the training of an IT person."
 

Pricing and Cost Advice

"The overall pricing for iboss is very competitive and transparent."
"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."
"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 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."
"The pricing is fair."
"This product is not expensive."
"We have an educational licensing agreement. It's a customer agreement for multiple years."
"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."
"I'm not totally involved in the pricing part, but I think its pricing is quite aggressive, and its price is quite similar to Netskope. Netskope has separate licensing fees or additional charges if you want to monitor certain SaaS services, whereas, with MCAS, you get 5,000 applications with their Office 365. It is all bundled, and there's no cost for using that. You only have the operational costs. In the country I am in, it is a bit difficult to get people with the required skill sets."
"Microsoft offers bundle discounts and a pay-as-you-go option."
"It has pretty good pricing."
"The pricing is a little bit high but right now, we are okay with it because of the compatibility with Office 365, Teams, and Azure AD."
"It is costlier than other solutions."
"If we need any extra features, the price will increase."
"​Be aware that you will need to invest some time and money to adapt your environment for Zscaler (traffic redirection, software deployment, authentication, etc).​"
"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."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"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."
"It is a few pounds per user per month."
"ZIA follows a subscription model pricing and charges you based on the number of users. I would say its price is good."
