CTO at Klaatu IT Security Ltd
Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…
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.

Quotes from Members

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

Pros

"Agari gives us visibility of our domain security, helps us manage our SPF, DKIM and DMARC records, prevents spoofing of our domains for phishing and ensures that our marketing and other emails are received correctly and not rejected as spam."
"It is really important for large companies to have the brand protection that is provided by Agari."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"They are very flexible as far as feature requests go."
"Agari offers very good brand protection and they are the core founder of the DMARC standard."
"It comes with a lot of helpful tips for complicated areas."
"I rely on Trellix Collaboration Security because the sensors are highly reliable and high-performance sensors that can handle traffic efficiently."
"We can control this solution from the cloud and are able to access it from wherever we are."
"Trellix Collaboration Security has positively impacted my organization by improving security, making teamwork more effective, and ensuring collaboration has become smoother."
"One of the most valuable features is the protection against vulnerabilities, particularly through virtual patching."
"After implementing Trellix Collaboration Security, we have not encountered any incidents related to ransomware."
"The product protects my email."
"Trellix Collaboration Security has positively impacted our organization by making our collaboration environment very safe, allowing our team to share files and links without worrying about threats."
"Trellix Collaboration Security is valued for being a stable and comprehensive solution that fulfills customer needs."
 

Cons

"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"We're not really that satisfied with technical support. They are too slow to respond."
"The solution needs better support."
"The spam detection feature could be better."
"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."
"I deduct two points because while we are using it for insiders, we still rely on another solution for gateway level security, which makes us use two different solutions for the same purpose."
"In general, our company should make the tool more robust to protect our systems."
"The custom tailoring is limited."
"The reporting aspect of the solution needs improvement."
 

Pricing and Cost Advice

"The tool is not expensive and I would rate its pricing a four out of ten."
"The price of the licensing is based on the volume of email."
"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"The solution requires a license to be purchased for every user."
"The licensing is on a yearly basis."
"I rate the product price as nine out of ten, where ten is the most expensive, and one is the cheapest. There is no need to pay any extra charges apart from the licensing costs."
"The cost is very high."
