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.

Network Architect at IP Dimension
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

"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."
"The console is cloud-based, which is something I really appreciate."
"First of all, the security policies are essential. I do not have to rely solely on Active Directory for our users."
"Iboss is a solution that prevents advanced persistent threats, and has a zero tolerance for attacks."
"Granular setup, which was able to set different levels of filters using the OUs in the AD."
"iboss is pretty scalable. They provide good support. The case managers you work with to coordinate what you need are pretty good."
"iboss is among the few products providing inline filtering where no application is needed on the device."
"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."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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 simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"It is a stable solution."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"This solution is easy to understand and easy to configure."
"The solution has different options that can be used to differentiate DDoS attacks."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"It's good, it keeps the spam out."
"The initial setup is very straightforward."
"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 solution's performance is good."
"We like the content filtering and secure messaging features."
"The most valuable feature is the DMARC Analyzer."
 

Cons

"I'd like to see them accelerate development on the security side, particularly around data loss prevention."
"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."
"The solution could be stronger on the integration side and offer more cloud applications like G Suite or Oracle."
"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."
"The area I would like to see improvement in is the ability with in the reporter to navigate directly to the content the user is traversing. It is kind of there, but it's not perfect. Quite frequently, I receive links that lead me to pages with error messages."
"Fold that in with the risk intelligence they're getting from all of the different subscriptions they are a part of. Now, these security companies subscribe to things like emerging threats, databases, etc. You can fold all this intelligence to decide what's happening on an endpoint. I would love to see them start moving into that space. That would compete directly with Microsoft. Maybe that's why they haven't. Having that ability native within the solution would be great. The other area in which I would love to see improvement is more detailed descriptions of why they block websites."
"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."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The onboarding process can be improved a little bit."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The initial onboarding was causing us some confusion."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"External security features need improvement."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"They should improve the cookies management feature."
"The filtering needs more flexibility."
"Its pricing can be improved. It is a bit expensive."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
 

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."
"The overall pricing for iboss is very competitive and transparent."
"It is expensive compared to one of its competitors."
"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."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"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's pricing lacks transparency."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The customers can select the license packages as per their requirements."
"The solution is expensive."
"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 product price is moderate. I rate the pricing a five out of ten."
"I'm always going to say the price needs to be lower, but it's reasonable."
