There is definitely a return on investment when using Mimecast, as it blocks phishing emails, reducing the risk of significant financial losses.

Room For Improvement

F5 BIG-IP APM requires improvements in pricing, cloud integration, user interface, documentation, support, and additional features for enhanced performance.
Mimecast Advanced Email Security needs better support, user experience improvements, cost reduction, and advanced AI integration for effectiveness.
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.

Our iboss subscription access should be more secure with an OTP or VPN etc.
If I could copy and paste objects instead of picking and configuring them from scratch each time, it would be great.

The main improvement needed for F5 BIG-IP Access Policy Manager (APM) is to integrate into the cloud-delivered services from F5.
Business Development Manager at Pylones
The ability to run the Anycast feature would be valuable, as the current solution only operates on-premises.

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

Setup Cost

F5 BIG-IP APM is costly but valued for high performance, with unpredictable cloud pricing and additional fees for features.

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.

Overall, my experience with pricing, setup costs, and licensing was smooth.

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.

Has provided reliable policy controls and secure web access for large enterprises
I consider Cloudflare when evaluating centralized access control features; Cloudflare utilizes multi-factor authentication and full API support, while F5 BIG-IP Access Policy Manager (APM) needs to enhance its API support. I recommend F5 BIG-IP Access Policy Manager (APM) for large companies such as Tüpraş and Ford. Tüpraş is one of the biggest companies in Turkey, along with other customers such as Tofaş, Euroko, Koç Holding, and more. For on-premises deployment, I would rate it a 10. For cloud deployment, I would rate it a seven. I primarily use it on-premises. I rate F5 BIG-IP Access Policy Manager (APM) eight out of ten.

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.
