Room For Improvement

Iboss struggles with Mac support, ISP integration in India, and needs improvements in security features and cloud integration.
Check Point Harmony Browse needs improvements in customization, integration, security, support, and user experience to meet diverse user needs.
Mimecast Advanced Email Security needs better support, interface, accuracy, simplified admin features, competitive pricing, and enhanced phishing detection.
It is not as intuitive as the rest of the platform.
Head of Cybersecurity at SES Water
We also had a problem with a transition when we upgraded from one appliance of theirs to another, but their engineer lost a good deal of our data.
Network Administrator at a educational organization with 51-200 employees
Our iboss subscription access should be more secure with an OTP or VPN etc.
The user interface can be better, and selecting the action for monitored or watch-listed IOCs can be more refined.
Security Operation Consultant at SecurView
Another area of improvement is extension compatibility since it currently works best with Chrome and Edge, but having wider browser support for Firefox and Safari would be beneficial for mixed environments.
Pre Sales Consultant at Redington Group
Integrating with Fortinet, Palo Alto, or third-party SIEM products such as Splunk would be a seamless advantage.
Information security professional at a financial services firm with 51-200 employees
When you buy an XDR provider, they give you a complete holistic story around it, showing what has happened, which email somebody has clicked on, whether there have been any changes, and whether there is any network activity.

Senior Tech. Lead at WE
Mimecast Email Security is somewhat expensive compared to the competition in the Indian market.

Setup Cost

Iboss offers competitive, transparent pricing with valuable cloud solutions, appealing to enterprises for predictable budgeting and desired functionality.
Check Point Harmony Browse is flexible, scalable, and valued for easy setup, beneficial pricing, and effective security for organizations.
Mimecast Advanced Email Security is costly, with some users valuing its ROI, while others find it non-competitive.
It offers the same features you would get from a vendor that charges 250,000 British pounds for a fraction of the price.
Head of Cybersecurity at SES Water
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.
Network Administrator at a educational organization with 51-200 employees
Regarding pricing, setup costs, and licensing, iboss is not cheap, and that's my only concern.
Managing Director
Smaller projects tend to be more expensive due to fewer licenses, while larger projects of 500 to 2,000 users benefit from better pricing and discounts.
Security Solution Architect at TD SYNNEX
There were no significant upfront hardware or infrastructure costs since it's delivered as a native cloud service.
Assistant Manager at a computer software company with 201-500 employees
It is not too high compared to what we expected, but it is not too cheap either, which is why I rate it five.
Information security professional at a financial services firm with 51-200 employees
The pricing is higher for Mimecast, particularly for the Indian market, where it is considered expensive.
Senior Tech. Lead at WE
Regarding the price, I think that in terms of similar products, it is pretty much in the same line, so I think it's reasonable.
IT Manager at a logistics company with 201-500 employees
Overall, my experience with pricing, setup costs, and licensing was smooth.
Manager - EUC at Finthrive
 

Valuable Features

Iboss provides comprehensive cloud security with advanced features, enhancing data protection and management efficiency for network security.

The solution's mental health function can detect if someone needs help.

It's given us a lot more visibility into our computer assets that may be infected with viruses and also shows us people who have unusually large uploads or might be engaging in high-risk activities, such as searches or going to sites not categorized by their web crawler.
Educational Technology Coordinator at a performing arts with 201-500 employees
iboss was the best solution for us because, no matter what domain you were in, everything is under a single pane of glass, which is exactly what we wanted.
Managing Director
Everything is handled directly within the browser using a lightweight extension, delivering real-time threat prevention, including protection against zero-day phishing and malicious downloads without impacting user productivity.
Pre Sales Consultant at Redington Group
The isolated environment in Check Point Harmony Browse is the best feature we provide, giving a separate, isolated environment for the production applications and company applications, which is really valuable.
Information security professional at a financial services firm with 51-200 employees
The real-time Threat Intelligence feature powered by Check Point's ThreatCloud is impressive because ThreatCloud integrates and correlates all malicious data from Check Point installations globally, collecting and analyzing this data with AI and machine learning to help prevent zero-day attacks effectively.
Security Solution Architect at TD SYNNEX
There was a signature phishing scam on the internet, but Mimecast Advanced Email Security caught it before it came to fruition and instantly blocked that signature-based phishing scam.
System Engineer II at a media company with 5,001-10,000 employees
It easily generates reports about the kinds of emails coming in weekly and classifies them into various categories, making it very helpful to analyze and ensure our email gateway remains safe and secure by updating all security patches.
Senior Managing Consultant at a tech vendor with 10,001+ employees
A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently.

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Phishing prevention and advanced threat protection have improved security for remote workers
Some of the best features that Check Point Harmony Browse offers include real-time phishing and malware protection, which inspects website links in real time and blocks phishing attempts and malicious downloads before they reach the user. Zero-day threat prevention, including built-in zero-day prevention, is a significant differentiator. It provides a seamless user experience since it runs directly inside the browser without slowing down browsing or requiring a VPN. This allows employees to securely access web and SaaS resources without realizing there's an extra layer of security. These features make a big difference for our team and company, such as in a particular situation where it helped us. We received a fake O365 page that posed a sophisticated phishing threat, and instead of relying solely on user awareness, Check Point Harmony Browse blocked the site in real time. This action prevented credential compromise and saved our security team from a potential incident response. Another crucial feature is the smooth integration with SaaS applications such as Teams, Zoom, or Google, which does not interfere with their operation. Users don't even notice there is any security tool running; it feels like security without friction.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks
Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.
