Executive Summary

Review summaries and opinions

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

ROI

Sentiment score
4.5
Sublime Security reduces security risks and costs, enhances efficiency, and streamlines email investigations, improving organizational operations.
Sentiment score
8.0
Trellix Collaboration Security boosts ROI by reducing incidents, improving efficiency, and lowering manual workload and false positives.
Importantly, we didn’t need to hire any additional staff; we were able to absorb this responsibility using our existing team.
Manager Security Operations Center at a educational organization with 10,001+ employees
I estimate that we have improved our efficiency, especially for phishing campaigns where we can handle multiple similar emails together, which has reduced repetitive analyst work and improved our response time.
Soc Analyst at a manufacturing company with 10,001+ employees
I think the ROI for us is primarily in reduced security risk and reduced analyst time.
Technical Lead at a consultancy with 11-50 employees
I have seen a return on investment with Trellix Collaboration Security; specifically, money was saved and fewer employees were needed because I do not need employees on different sites.
Network & Security Lead at Net-International
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.
Endpoint Security Analyst at BNP Paribas
I have seen a return on investment from using Trellix Collaboration Security as we have saved time and reduced security incidents, improving our overall effectiveness.

Customer Service

Sentiment score
6.3
Sublime Security offers highly rated customer support with efficient responses, expert teams, and excellent communication channels for quick resolutions.
Sentiment score
6.8
Trellix Collaboration Security support is mixed; praised for knowledgeable service but criticized for inconsistent response times globally.
We were able to get in touch with the person who constructed the LLM and its agentic aspects relatively quickly to address our questions.
Manager Security Operations Center at a educational organization with 10,001+ employees
They're able to understand the context of an incident rather than just treating it as a generic support ticket.
Technical Lead at a consultancy with 11-50 employees
I would rate customer support ten out of ten.
Soc Analyst at a manufacturing company with 10,001+ employees
My experience with the Indian support team was not as satisfactory since they did not provide adequate support to rectify issues.
Network & Security Lead at Net-International
They have dedicated email security support engineers.

Scalability Issues

Sentiment score
7.1
Sublime Security is highly scalable and resource-efficient, effectively handling large email volumes across Microsoft 365 and Google Workspace.
Sentiment score
8.0
Trellix Collaboration Security is highly scalable, adaptable, and efficiently manages environments, but licensing may impact scaling.
Despite nearly doubling the number of mailboxes and adding significantly more detection rules, the service remains just as fast as it was when we first implemented it.
Manager Security Operations Center at a educational organization with 10,001+ employees
Its scalability is also good, as it can scale with the number of protected mailboxes or users, or as email volume grows, supporting enterprise development across Microsoft 365 or Google Workspace.
Soc Analyst at a manufacturing company with 10,001+ employees
We have a fairly large Microsoft 365 environment and haven't had any problems with the platform keeping up with our email volume.
Technical Lead at a consultancy with 11-50 employees
Scalability benefits me by allowing for growth.
Cyber Security Engineer at a tech services company with 11-50 employees
Trellix Collaboration Security scalability allows me to use sensors on-cloud, on-premises, inside premises, and in a hybrid environment.
Network & Security Lead at Net-International
Trellix Collaboration Security is very good when it comes to scalability, demonstrating impressive capacity for growth.
Endpoint Security Analyst at BNP Paribas
 

Stability Issues

Sentiment score
8.7
Sublime Security offers stable, reliable email security with quick performance, efficient threat detection, and no downtime or crashes.
Sentiment score
8.2
Trellix Collaboration Security offers high stability and reliability, with rare issues primarily during complex API integrations across environments.
Sublime Security acted quickly; once Microsoft alerted Outlook about the incoming email, Sublime Security managed to pull it from the stream before it had a chance to appear in the user's inbox.
Manager Security Operations Center at a educational organization with 10,001+ employees
Sometimes, integration can be challenging, impacting its stability.

Room For Improvement

Sublime Security should enhance user onboarding, integration, customization, and reporting while addressing pricing and reducing false positives.
Trellix Collaboration Security needs improved reporting, customization, interface, language support, and stronger data loss prevention capabilities.
Often I have to prepare reports for our CEOs, and they want it in a less technical way, a simpler view of things such as threats blocked, incidents investigated, and overall risk reduction.
Technical Lead at a consultancy with 11-50 employees
While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value.
Manager Security Operations Center at a educational organization with 10,001+ employees
One breach could potentially put a small company out of business, so having a tool such as this might save them from that fate.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
I would like to see the addition of email digital protection features, such as anti-spam and antivirus, not just sandboxing, in the on-premises solution.
Senior Team Leader at BMB
To improve vulnerabilities, Trellix can use an automation process to check if the system is vulnerable.
Network & Security Lead at Net-International
Trellix Collaboration Security is working smoothly.

Setup Cost

Sublime Security's pricing is higher but justified by effective threat prevention, with competitive AWS Marketplace setup and licensing.
Trellix Collaboration Security's pricing varies, seen as affordable by some but costly for smaller businesses, with flexible licensing options.
I can also understand why some people might say it's expensive.
Technical Lead at a consultancy with 11-50 employees
It's competitive with its peers, especially for the number of mailboxes we have.
Manager Security Operations Center at a educational organization with 10,001+ employees
It is quite expensive and should be reconsidered.
Cyber Security Engineer at a tech services company with 11-50 employees
The setup cost was very cheap.
Network & Security Lead at Net-International
My experience with pricing, setup cost, and licensing for Trellix Collaboration Security is that pricing and setup were reasonable and licensing was straightforward.

Manager Security Operations Center at a educational organization with 10,001+ employees
Improves decision-making with clear verdict explanations and works well across multiple environments
I know that a lot of time has been invested in improving the efficacy of the platform, and it shows; it performs very well. Moving forward, I think our focus should be on how to achieve better integration with other systems. While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value. This would allow it to be integrated more closely with the workflows of various teams and could potentially increase its market appeal. From my perspective, the tool itself functions exceptionally well, which gives me confidence in the system. I want to see this functionality extend to other tools that I use, enabling faster automation and improved workflows for the team, particularly from a security operations standpoint. I have no critiques regarding the tool itself. They've done an outstanding job and are maintaining high quality throughout their development process. They have a great product, and it's essential that they continue to uphold that standard, even though it requires significant effort.
Jorge Abalo - PeerSpot reviewer
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.
