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.

Cloud security has improved remote access and has reduced costs for smaller client sites

I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

Email security has protected critical communication but hyperlink handling still needs improvement

We have been using Mimecast Web Security for quite a lot of years. Regarding the analytics part you asked and what metrics are most valuable for monitoring web activities in our case, we am not dealing with the monitoring; that's our MSP who does the majority of the monitoring on our behalf. Regarding the reporting part, I have seen the original reports from Mimecast Web Security, which seem to be quite heavy in terms of information. With the MSP, we are just reviewing and discussing what is necessary. If there is a concern, that is dealt with MSP immediately rather than waiting for formal conversations. However, I think the Mimecast report is fine and easy to read. It is hard for me to say whether the installation is easy or complex, as I wasn't involved; it was done by our MSP. I am the end customer of Mimecast Web Security, not a consultant.

Quotes from Members

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

Pros

"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."

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

"Technical support is pretty sharp and very responsive."

"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."

"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."

"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."

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

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

More iboss pros

"Cloudflare is by far the most effective solution that I have come across."

"The solution has different options that can be used to differentiate DDoS attacks."

"Cloudflare is simple to use."

"It is a stable solution."

"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."

"I'm very satisfied with the environment and the dashboard."

"Cloudflare, in my opinion, was easy to implement."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

More Cloudflare One pros

"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."

Cons

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."

"Its pricing could be better."

"The dashboards for local use could be better."

"Sometimes, obviously, there are bugs."

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

"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."

"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."

More iboss cons

"Cloudflare DDoS has poor technical support."

"Operating and tuning the product is difficult."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"They don't have a person to provide support for customers using the solution under their free plan."

"Our subscription plan for the solution has a limitation of bot signatures."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

More Cloudflare One cons

"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."

"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."

Pricing and Cost Advice

"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."

"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."

"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"Cloudflare Zero Trust Platform's pricing is good."

"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The solution's pricing lacks transparency."

"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."

"The prices are slightly expensive."

"The solution is not that expensive."

"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
