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.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

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

Pros

"It was a very easy product to install. It can be deployed very fast."
"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."
"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."
"I would rate the technical support of iboss a solid 10 without a shadow of a doubt."
"The console is cloud-based, which is something I really appreciate."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"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."
"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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare is by far the most effective solution that I have come across."
"This solution is easy to understand and easy to configure."
"Cloudflare is simple to use."
"The blocking feature is very good."
"Cloudflare DDoS mitigates DDoS attacks."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"Email security is the most valuable feature of the solution."
"I would rate Mimecast Email Security a nine out of ten."
"The solution is pretty straightforward to use and easy to set up."
"The setup was easy."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
 

Cons

"Iboss is growing so fast that it is often hard for them to keep up with the challenges."
"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."
"File integrity monitoring would be very advantageous as an additional feature."
"The reporting feature needs improvement."
"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."
"To scale up, a new iboss Node Blade Chassis must be purchased."
"The dashboards for local use could be better."
"The initial onboarding was causing us some confusion."
"Cloudflare DDoS has poor technical support."
"For the topic of improvement, providing some training material is one of my suggestions."
"Our subscription plan for the solution has a limitation of bot signatures."
"The response time for support must be reduced."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The solution is very expensive."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"The installation is not so straightforward."
"The product's interface could be improved to be more user-friendly."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
 

Pricing and Cost Advice

"It is probably in line with other solutions, but I do not deal with the financial side."
"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."
"We have not priced the solution recently, but they were competitive with other vendors in the past."
"The overall pricing for iboss is very competitive and transparent."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"The prices are slightly expensive."
"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."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"The licensing costs are per-user for the product that you get with them."
"The product has good pricing in terms of return on investment."
"The customers can select the license packages as per their requirements."
"For what it is, the product is overpriced."
