Executive SummaryUpdated on Jun 2, 2026

Trellix Collaboration Security and Mimecast Advanced Email Security compete in email protection and threat detection. Trellix appears to have the upper hand due to its comprehensive protection for collaboration platforms, while Mimecast excels in targeted threat protection and straightforward email security integration.

Features: Trellix offers GTI threat intelligence, customizable dashboards, and high-performance sensors. These features enhance team productivity and ensure comprehensive collaboration protection. Mimecast is known for its reliable sandboxing, strong spam filtering, and malware detection, which keep malicious content from users. It is easy to integrate with Microsoft 365, benefiting organizations that require straightforward solutions.

Room for Improvement: Trellix could improve protection against zero-day attacks and enhance its reporting tools, spam detection, and customization capabilities.

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.

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.

Jorge Abalo

Endpoint Security Analyst at BNP Paribas

Endpoint protection has strengthened network control and has simplified global threat response

In my opinion, the best features Trellix Collaboration Security offers include the firewall, the on-access scan, and the ability to obtain daily signatures for the latest malware. These daily signatures, referred to as content, ensure that we are protected against the most recent malware threats recognized by other companies. Another feature I particularly enjoy is the capability to maintain different locations that can communicate with the fabric, or DXL fabric as I refer to it, allowing me to create something akin to an EDR for immediate responses to resolve issues. The DXL fabric has helped my organization by enabling communication between different locations, such as one in Europe, another in South America, and one here. This fabric communicates with a broker that interacts with the TIE servers, which maintain the reputation of files, certificates, and known signatures from various regions including Europe, South America, and Canada. When something suspicious occurs, such as a certificate appearing malicious on an application, I can easily click and indicate that I trust this file, and through the fabric, I can apply an exclusion for that application across all locations simultaneously. Other features I find valuable include the SSO integration with Trellix EPO, specifically SAML SSO, allowing people not to have to manage usernames and passwords if they already utilize an SSO service for SAML; I consider this functionality to be quite beneficial.

Quotes from Members

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

Pros

"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."

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

"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."

"Cloudflare DDoS mitigates DDoS attacks."

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

"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."

"Cloudflare is simple to use."

"It will take the blow rather than our applications should an attack occur."

More Cloudflare One pros

"The product is good. To date, we have not faced any challenges."

"Mimecast Advanced Email Security proves to be a useful tool, allowing me as security personnel to work in a more peaceful manner."

"Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."

"It's good, it keeps the spam out, and it does a really good job at not allowing threats through."

"Email security is the most valuable feature of the solution."

"The initial setup is easy."

"Mimecast is pretty good, even if you're on Office 365."

"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."

More Mimecast Advanced Email Security pros

"I like FireEye's filtering, spam digests, and its advanced threat review of email flow. It also has a broad range of riskware rules you can deploy."

"It is one of the greatest solutions to have or to complement any other security solution such as Proofpoint or IronPort."

"The solution's most valuable feature is its simplicity. It's very user-friendly."

"What I find most valuable with the solution is that it can integrate with cloud solutions, such as Google and Microsoft. Additionally, the solution is easy to use."

"Many similar solutions don't normally protect clients from malware, but FireEye does a very good job of protecting systems."

"FireEye is good for malware depicting and security."

"The product helps reduce the number of malicious emails reaching the user's inbox."

"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."

More Trellix Collaboration Security pros

Cons

"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."

"Our customers no longer use Cloudflare because its service is subpar."

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

"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."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"The onboarding process can be improved a little bit."

"The response time for support must be reduced."

More Cloudflare One cons

"I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats."

"Mimecast needs to reduce the number of false positive emails; a big pain point for us."

"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."

"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."

"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."

"I'd like to have better support from the product in the future."

"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."

"The solution should include more AI features instead of Mimecast's more general static configuration tooling."

More Mimecast Advanced Email Security cons

"The solution is not easy to set up. However, we have employees that have the knowledge that can do the difficult implementation. It would be better if the process was easier."

"The reporting aspect of the solution needs improvement."

"The solution must provide features to scan QR codes for threats."

"Trellix Collaboration Security can be improved by making the reporting and analysis tools more detailed."

"Sometimes especially zero-day spam emails can be passed to the user's inbox."

"I observe that the return on investment is hindered by the lack of adequate training opportunities, with Trellix's own training being quite costly, ranging from 2,000 to 4,000 dollars, which many small or medium-sized businesses cannot afford."

"In general, our company should make the tool more robust to protect our systems."

"There is a need for improved integration with totally different products, such as a rapid server."

More Trellix Collaboration Security cons
