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.

User access is simplified and secured through central core functionalities
The simplicity and logical structure of Zscaler make it easy to use and administer. It allows grouping, enabling en masse access conveniently. Unlike the BlueCoat proxy, which was more prescriptive and individual-focused, Zscaler offers group access. Additionally, Zscaler's modern tools enhance the network architecture by passing everything through a central core of security, ensuring everything is secure before accessing the internet.

Pros

"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 security aspect of the solution, particularly the malware behind it, is excellent. That's something that really helped us out. It's not just a simple proxy that just blocks the insights of potential threats that come on behind it. They do malware detection and that helps us a lot."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"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."
"Its initial setup was straightforward."
"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."
"Defender's integration with our identity solutions is critical in our current setup."
"The most valuable feature is the alerting system."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"The most valuable feature of Microsoft Defender for Cloud Apps is that we are primarily using only the Defender for Cloud on the Azure Cloud."
"Defender for Cloud Apps has given us good visibility regarding what we've allowed into our environment until now."
"Microsoft Defender for Cloud Apps is very comprehensive, providing a complete 360-degree view of applications within an organization."
"There are a lot of features with benefits, including discovery, investigation, and putting controls around things. You can't say that you like the investigation part but not the discovery. Everything is correlated; that's how the tool works."
"The most effective features for data protection are data loss prevention (DLP) and data classification."
"Zscaler Private Access (ZPA) is more secure than these particular VPN solutions."
"Zscaler Private Access helps by resolving network choke issues, allowing application access from public networks without needing to integrate with internal networks."
"Zscaler Private Access (ZPA) is the most mature compared to other vendors in terms of features and stability."
"Zscaler ZPA is easy to administer and is organized in a straightforward and logical manner."
"The scalability is amazing. Whenever we need to upgrade the users, it increases immediately."
"Zscaler Private Access helps by resolving network choke issues, allowing application access from public networks without needing to integrate with internal networks."
"Zscaler has allowed an easy, secure way for us to access our internal resources from outside."
"It provides security and has a great service user experience."
 

Cons

"The reporting feature needs improvement."
"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"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."
"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."
"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 dashboards for local use could be better."
"Our biggest problem with their service was it did not recognize the device and filtering did not always work correctly."
"We sometimes get errors when we create policies, which is somewhat annoying because some policies stop working due to misconfigurations. We find this challenging because it limits our options for troubleshooting an issue."
"I believe it's only set to be integrated with Microsoft Defender for identity and identity protection. I would like to see it available for use with something like Office 365 Defender. I don't think it's integrated with that yet."
"We are having trouble with our continuous reporting configuration and struggling with configuring the collector properly with our log parsing."
"There could be more granular roles that are out of the box included in the product."
"There are some features, such as user navigation content filtering, that are disabled by default, and it probably makes sense to enable them by default."
"I want them to enhance in-session policy."
"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."
"I would like more customization of notifications. Currently, you either get everything or you get limited information. I would like to have something in between where we can customize the data that is included in notifications."
"There are some bugs in the solution."
"One area for improvement is setting posture profiles for vendor machines."
"Zscaler restricts customization to a maximum of 256 customizable rules, which can be a limitation for us."
"There are some bugs in the solution, which they are clearly working on, and they are still not resolving them. So it's taking some time."
"Sometimes connection errors occur when users are unable to connect to the particular cloud."
"The lack of control over the 700+ external IPs through which traffic exits Zscaler is problematic."
"The price is a concern as it increases every year and becomes more expensive, driving customers and other vendors to look for alternatives."
"Customer service and support are rated seven or eight out of ten, needing improvement in quality and response time."
 

Pricing and Cost Advice

"It is expensive compared to one of its competitors."
"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."
"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 a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."
"The E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."
"The price could be better and should be reconsidered."
"Its pricing is on the higher side. Its price is definitely very high for a small-scale company. As an enterprise client, we do get benefits from Microsoft. We get a discounted price because of the number of users we have in our company. We have a premier package, and with that, we do get a lot of discounts. There are no additional costs. It only comes in the top-tier packages. Generally, the top-tier license is the best license that you can get for your organization. If you want, you can buy it separately, but that's not a good idea."
"Microsoft offers bundle discounts and a pay-as-you-go option."
"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."
"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
"This product is not expensive."
