Enhances web security with a single pane of glass and flexible deployment

I don't see any need for improvement; one of the really good things about iboss as a company is that they listen to customer feedback. I have suggested enhancements, and they are responsive, making changes for the better, and they do a lot of testing. To improve iboss, although we haven't used it, we considered the VPN solution that comes with the highest tier licensing, which includes DLP and various other add-ons. We prefer using another product which automatically logs you back onto your network when turning on your PC. With iboss, the connection is manual, which doesn't meet our needs. Additionally, sizing can be tricky because, although the initial recommendations may seem adequate, actual usage may require more gateways than anticipated.

Ensures internet navigation safety and boosts productivity

The features of Cisco Umbrella I prefer most are DNS protection and traffic redirect. With Cisco Talos's threat intelligence, we reduce the impact of malware traffic in our network, and we currently see the behavior of equipment and choose the correct sites. Cisco Talos has helped us reduce the impact of malware traffic. We can see the behavior and choose the correct sites. We're currently testing secure access with Umbrella in order to secure access to core applications. It's a product that the user doesn't even know is there, even though it is protecting them. It's not hard on the equipment. And, for us, it centralizes everything, which improves productivity. With the Experience Insights feature of Cisco Secure Access, we've seen impacts on the management of user connectivity by allowing us to deliver safe connectivity. We are testing the Secure Access product with Cisco Umbrella to improve our connectivity with our users in order to secure access to the corporate applications. Cisco Umbrella is in the cloud, which is nice.

Security and Continuity Manager at Rolinco NV

Deployment has been seamless with insightful data categorization and enhanced control

The features of Microsoft Defender for Cloud Apps that I have found most valuable include the overall portal view, with bubble graphs which give us insight into what goes where in the categorization, nowadays with Generative AI but all kinds of categorization, collaboration, etc. That central view of the portal is very useful for us. 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. Therefore, we can add more control, and we have already done so. This was not possible in the old solution, in the old CASB solution with Netskope. We now can see on the spot, and we do that almost weekly, what the end users are utilizing, which cloud providers or cloud apps they're using. The visibility into OAuth apps provided by Microsoft Defender for Cloud Apps is very good. The visibility into risk and risk management of our organization's Generative AI apps is very nice, as you can choose the category Generative AI and then see exactly what traffic has been going to and from Generative AI in the cloud. This makes us very insightful on what is used within the company. We have some policies on blocking specific Generative AI, and we use within our company one particular AI part, which is CoPilot of Microsoft. In this way, we can see what the end users are using other than CoPilot, and that makes us more in control. The effectiveness of the integration of Microsoft Defender for Cloud Apps with Defender XDR and defending against SaaS attacks is very intuitive. It works immediately if we create a new policy or in Purview or in Microsoft Defender for Cloud Apps, or when we make an app unsanctioned by blocking it, then it is almost immediately, or at least within a couple of hours, effective on all the endpoints where the EDR is running. This gives us much better control over things than before.

Quotes from Members

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

Pros

"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."

"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."

"Its initial setup was straightforward."

"We chose iboss for both zero trust and proxy (SWG) because their SWG was superior."

"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."

"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."

"The console is cloud-based, which is something I really appreciate."

More iboss pros

"The agent that gets installed on the endpoints or on people's laptops and devices is a Cisco AnyConnect Umbrella module. It's one of the most impressive things because you are able to protect your users anywhere they are."

"Provides dependable DNS monitoring of external devices."

"We can have a full overview and a quick overview of all the DNS requests. For us, it's quite important."

"We like Cisco Umbrella because of DNS security. It's one step ahead of whatever we are using for regular web filtering. In that way, it's more secure than other web filtering products."

"The customer service and technical support of Cisco Umbrella are great."

"When we have laptops that leave the building, they could connect to public WiFi before they establish a VPN connection back into the company. For that duration or that period of time when they're not docked in the network or on a VPN, they effectively don't have that full layer of security that I provide inside the building. This tool stands in during that period of time, and we extend the security settings through their basic firewall or their cloud-based firewall at that time. So, we do content filtering and control access, but they also are looking at new domains, IP addresses, and bad requests. They're blocking them on my behalf when a laptop is not sitting behind our security appliances."

"The initial setup is very easy and takes only a few minutes."

"The core business of Cisco Umbrella is non-malware. That's all it does: block the malware on the gateway."

More Cisco Umbrella pros

"The most valuable feature of Microsoft Defender for Cloud Apps is to stop shadow IT."

"The compliance capabilities of Microsoft Defender for Cloud Apps are quite extensive."

"Better logging allows us to find problems and take appropriate steps to lock them out."

"The solution does not affect a user's workflow."

"Defender's integration with our identity solutions is critical in our current setup."

"It's very easy to install and it includes the Intune portal from Microsoft where I can control all the devices from one place."

"It does a great job of monitoring and maintaining a security baseline. For us, that is a key element. The notifications are pretty good."

"If your business requirements are relatively simple, it can get the job done."

More Microsoft Defender for Cloud Apps pros

Cons

"The reporting feature needs improvement. It doesn't give you the expected results. It is quite difficult to get the specific reports needed, and it is not as intuitive as the rest of the platform."

"If they could implement an extra security layer preventing access to iboss from the open internet, it would be great."

"File integrity monitoring would be very advantageous as an additional feature."

"SSL decryption: We had issues with learners using apps instead of using web browsers. This type of encryption is tough for any appliance in a BYOD environment."

"The dashboards for local use could be better."

"To scale up, a new iboss Node Blade Chassis must be purchased."

"Sometimes, obviously, there are bugs."

"The reporting feature needs improvement."

More iboss cons

"It would be good to have more extensions to third-party products and a client for other device types."

"I would like them to make some videos, practical videos, the kind with steps that people can use to learn and deploy"

"They can maybe simplify the configuration. For example, sometimes, the proxy part is quite difficult, and that's why we didn't deploy that."

"From my perspective, I would Cisco Umbrella to give more exposure to my sales engineers. I know I can call them whenever I have an issue, however, more frequent meetings would be awesome."

"I would like to see more integrability with other products."

"The pricing is a bit high. Being outside of the USA, we have issues with the exchange rate."

"Cisco Umbrella should add some more documentation on proxies."

"Missing a real data leakage prevention solution."

More Cisco Umbrella cons

"Microsoft Defender for Cloud Apps' initial setup was quite technical but we were prepared. The time of the implementation depends on the job and how many users are being set up."

"The integration with macOS operating systems needs to be better."

"There are challenges with detection and there are challenges with false-positive rates."

"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."

"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."

"It takes some time to scan and apply the policies when there is some sensitive information. After it applies the policies, it works, but there is a delay. This is something for which we are working with Microsoft."

"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."

"We are having trouble with our continuous reporting configuration and struggling with configuring the collector properly with our log parsing."

More Microsoft Defender for Cloud Apps cons

Pricing and Cost Advice

"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 expensive compared to one of its competitors."

"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 probably in line with other solutions, but I do not deal with the financial side."

"The pricing is pretty fair. It's good."

"Its value exceeds its pricing."

"The licensing part for Umbrella is really flexible."

"Pricing depends on the automation requirements of the organization."

"Cisco solutions are generally perceived to be rather expensive. We have constant internal discussions as to whether we should offer lower-priced security solutions from some of the competitors."

"I think Cisco Umbrella is priced well. We have a mix of customers with different verticals such as education. We have clients in the commercial space as well. Umbrella is at a good price point for all of our customers."

"Our costs were negotiated, and they are okay."

"Cisco has a model called ELA. With ELA, if you buy the solution you will have the complete security portfolio and you can pay it yearly or after three years, it depends on the contract."

More Cisco Umbrella pricing and cost advice

"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."

"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."

"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."

"The pricing is in the middle. It isn't too cheap or expensive compared to other antivirus or security products. It is priced according to industry standards."

"The E5 license offers everything bundled. People are moving to Microsoft because you buy one license and it gives you everything."

"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
