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.

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."

"Content filtering is the most useful feature of iboss."

"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."

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

"Granular setup, which was able to set different levels of filters using the OUs in the AD."

"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."

"Because of iboss, I did not have to assign web filtering tasks to my techs on a daily basis."

"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."

More iboss pros

"The Global Block List is one of the most valuable features because it's really easy to block domain names as well as URLs. Sometimes you don't want to block the whole site, you just want to block one URL. The Global Block and Allow Lists are the best features for us."

"Threats never come close to your network with security at the DNS level."

"Cisco Umbrella offers DNS layer security, a secure web gateway, and cloud access security broker functionality."

"Stability-wise, it's good. I have never encountered any bugs."

"The most valuable feature of this solution is its reliability."

"One of the most important features is the security posture check which Umbrella offers when a user accesses any website. That is one of the most unique features that it offers."

"Cisco Umbrella is easy to monitor, manage, and deploy."

"It blocks malicious DNS queries daily which is very beneficial."

More Cisco Umbrella pros

"The most valuable feature is its policy implementation."

"I would rate it a ten because I have not experienced any stability issues so far with Defender for Cloud Apps."

"The most effective features for data protection are data loss prevention (DLP) and data classification."

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

"The most valuable features of Microsoft Defender for Cloud Apps include live, up-to-date information, which provided real-time alerts, and the ability to delve into detailed metadata information."

"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."

"The raw logs that come directly from Microsoft Defender for Cloud Apps contain all the data I need, and the ability to track activities happening on cloud applications and the alerts provided is an interesting aspect."

"The integration within the entire Defender suite is highly valuable because it allows for communication between different components and offers pretty decent correlations."

More Microsoft Defender for Cloud Apps pros

Cons

"For zero trust implementation, we encountered complexity issues, especially with a large infrastructure company ExxonMobil."

"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."

"Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern."

"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."

"The reporting feature needs improvement."

"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."

"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."

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

More iboss cons

"There are some situations where we would like to block things for specific user groups. I know that Umbrella does that, but it's not that easy.... when you want a specific task for specific rules and policies for user groups, you have to go three levels down in the menu, and it's hard to find where you do that task."

"The API is very Cisco orientated, which is absolutely fine if you're using Cisco Firepower and SecureX kind of products, but if you want to integrate with third parties, it is a bit tricky. There are some key API connectors for the more prevalent SIEM tools. I would really like to see in Cisco Umbrella the ability to create customized reports and then assign the rights to view these reports to people within a group. I should be able to create a customized report, which is viewable by anybody who has the rights. I should be able to create groups within Cisco Umbrella, and then assign reports to groups and have those reports split out automatically only to those groups. I can kind of do it by restricting my email list, but it is a half-complete way of doing it."

"The only thing I can think of is that I'd like to see a little more flexibility in policy creation. The way that policy is currently structured is like a "first hit succeeds" kind of policy. It would be nice if it were more hierarchical."

"The integration with Cisco could be better."

"I would like to see a graphical representation of the entire network."

"There are a couple of different pieces that have different portals. I know they're working on getting them all into one portal, but that's probably the biggest thing that needs improvement right now. It's not a single pane of glass yet."

"Instead of creating a TAC case, it would be better if we could just call in and they could answer us immediately."

"It could be improved by having a local data center and caching, which can provide protection support. I would like to be able to channel my intel and my network traffic to their clouds, and this feature is not available. Advanced protection or any malware file support, which might be required, is not available."

More Cisco Umbrella cons

"I want them to enhance in-session policy."

"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 areas of Microsoft Defender for Cloud Apps that need improvement are related to IAM, as they do not provide much support for local users."

"Sometimes the support is actually lacking."

"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."

"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."

"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."

"This service would be better if it had a separate license, only for this service, that could be used to track usage."

More Microsoft Defender for Cloud Apps cons

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 expensive compared to one of its competitors."

"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."

"The product is pricey compared to Cisco Firepower."

"Licensing fees are paid on a yearly basis."

"Cisco has a set price for a single license up to 100, but whenever we get over 100, we have to ask for a quote."

"We were using the free version, and we implemented the paid version about two months ago. I'm paying a fair price, but everything is negotiable with Cisco. One of the benefits that I got by having Cisco Umbrella is the licensing of the Cisco AnyConnect VPN client."

"Cisco Umbrella is expensive and could be cheaper."

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

"I rate the tool's pricing a five out of ten."

"Pricing and licensing of Cisco Umbrella is a bit confusing because you have to separate the DNS solution and the full-feature solution. Cisco in Portugal helped us understand which one was the right one for us."

More Cisco Umbrella pricing and cost advice

"The price could be better and should be reconsidered."

"We have an educational licensing agreement. It's a customer agreement for multiple years."

"It is a little bit expensive. When you want to have the complete package with Office 365, Defender, and everything else, it is expensive."

"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."

"The pricing is fair."

"It has fair pricing. You pay for what you get. As far as I know, there are no costs in addition to the standard licensing fee."

"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."

"Microsoft offers bundle discounts and a pay-as-you-go option."
