Trend Micro Email Security and Microsoft Defender for Office 365 are both prominent competitors in the email security market. Microsoft Defender holds an edge due to its seamless integration within the Microsoft ecosystem, effective integration capabilities, and zero-day threat protection.
Features: Trend Micro Email Security is known for its email filtering, antivirus protection, and spam filtering capabilities. It also offers strong anti-phishing and malware scanning. Microsoft Defender for Office 365 provides ease of use with robust anti-phishing measures, zero-day threat protection, and advanced AI-based threat protection.
Room for Improvement: Trend Micro Email Security could improve phishing email detection, enhance AI features, and make its interface more intuitive. Microsoft Defender for Office 365 could benefit from better phishing and spam filtering, clearer documentation, and improved support.
Ease of Deployment and Customer Service: Trend Micro supports hybrid, public, and on-premises deployments, with good technical support, though regional responsiveness can vary. Microsoft Defender is predominantly used in public and hybrid cloud environments and offers good technical support but has variable response times.
Pricing and ROI: Trend Micro Email Security is seen as costly, especially for smaller companies, but offers significant ROI. Microsoft Defender for Office 365 is bundled within the Office suite, making separate pricing evaluations difficult. It is considered expensive without an E3 or E5 subscription, yet its integration and functionality justify the cost for large enterprises.
It has also decreased our time to detection and response by about 15 to 20 percent.
Overall, cost of owning and operating our system goes down.
It's hard to quantify the return on investment we've seen from Microsoft Defender for Office 365.
Since Trend Micro launched in the Pakistani market, it has offered a great return on investment with competitive financial costing.
Over the past two years, there have been no critical problems.
we opened tickets, and they typically resolve them quickly.
With a subscription for Microsoft Defender for Office 365, it is an eight. Without it, it is a six.
We have local support here as well, with local Trend Micro engineers that visit the site whenever there is a high escalation case, arriving within hours if there is a geolocation difference, or within five to six hours.
Clients are generally very satisfied with the various types of support available.
The area of support that requires improvement would be the response time.
We have never faced scalability problems, and Microsoft manages it effectively.
Microsoft Defender for Office 365 scales transparently for us, as we grew from 1,000 users to 3,000 users, and we didn't notice much difference.
Microsoft Defender for Office 365 scales with the growing needs of my company well.
All of the SaaS modules I've worked with are highly scalable, and I do not face any reliability or availability issues while scaling.
We have a company that sends almost 2,000 to 3,000 emails per hour or more.
If you purchase credits in bulk, you can use them for any kind of solution.
I would rate the stability of Microsoft Defender for Office 365 as 10 over 10 because it's highly available, it works, and it does the job it is meant to do.
I have not experienced any downtime, crashes, or performance issues because of Defender.
The solution is stable, as we have been using it for the past two years.
Once your MX record and all configurations are in place, you don't experience downtime.
I have never experienced downtime with this platform.
The main area for improvement is simplifying the implementation and rollout process.
Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published.
There is a different console for different things; I just want one consolidated console.
If there is a product that can provide a centralized view Trend Vision One does, it really grabs the customer's interest because customers usually don't have to buy separate EDR, XDR, or SIEM solutions or a console for their SOC analyst or email security team.
I would apply different policies to classify or categorize emails such as spam or not spam and inspect the content of the email and attachments to check for viruses or malware.
The company also needs to work on pricing because it is quite costly compared to other products.
We've likely saved 30% of costs.
Money-wise, it is a part of the Office 365 suite, making it slightly more expensive compared to Trend Micro.
Microsoft is quite affordable with a lot of features available for any size organization.
Prices range from 11 to 12 dollars for licenses and can fluctuate up and down.
A great benefit is that if you buy a license for 100 servers and 100 mailboxes, and if your mailboxes increase to 120 while your servers decrease to 80, you can reallocate credits from unused email security to your mailboxes.
This is the biggest consideration companies think about when deciding to implement Trend Micro Email Security.
It ranks the threats and allows us to prioritize those hitting us the hardest, such as email threats.
It provides end-to-end visibility on email threats such as phishing, extending beyond Exchange Online Protection.
The value of the DLP feature is significant to us because we have internal data, sometimes sensitive, and the users may not always be aware of security and privacy, which might lead them to send out information mistakenly to external parties.
It does provide me with centralized visibility and management across protection layers. It can integrate all of the separate EDR, XDR, or SIEM solutions, and if you have cloud security applications, all can be integrated and viewed in a single console.
When we implemented Trend Micro Email Security, we found that about 80% of emails were blocked because they are phishing and spam.
The product is quite strong, and that is one reason most clients are replacing their existing email security solutions with it.
