Microsoft Defender for Office 365 and Microsoft Defender Threat Intelligence [EOL] compete in the cybersecurity market focusing on threat detection and protection. Microsoft Defender for Office 365 seems to have the upper hand due to its seamless integration within Office applications and comprehensive email protection.
Features: Microsoft Defender for Office 365 provides comprehensive email protection with anti-phishing, anti-malware capabilities, and Safe Links. It deeply integrates with Microsoft services, offering data loss prevention across various environments. Microsoft Defender Threat Intelligence [EOL] offers real-time threat detection and integrates well with other Microsoft products, providing proactive security insights.
Room for Improvement: Microsoft Defender for Office 365 could benefit from better phishing detection, more detailed reporting, and reducing false positives. There is also potential for enhancing integration with non-Microsoft applications and providing greater threat visibility. Microsoft Defender Threat Intelligence [EOL] needs stability improvements, better AI features, and more effective integration with non-Microsoft environments. It should improve user experience with more detailed alerts and streamline configuration processes.
Ease of Deployment and Customer Service: Microsoft Defender for Office 365 is adaptable to various cloud architectures, praised for its integration with Microsoft ecosystems and competent technical support, though its documentation can be challenging initially. Microsoft Defender Threat Intelligence [EOL] offers multiple deployment options but receives mixed reviews for support, with delays in resolving complex issues despite knowledgeable support staff.
Pricing and ROI: Microsoft Defender for Office 365 is bundled with Office 365 subscriptions, convenient for enterprises using Microsoft products, yet considered expensive. The ROI is significant due to protection enhancements. Microsoft Defender Threat Intelligence [EOL] is cost-effective within Microsoft bundles, but its standalone pricing is high, with licensing changes causing confusion for SMEs. Both solutions offer substantial security value, reducing incidents of ransomware and phishing attacks.
Successful phishing incidents and credential compromise attempts dropped noticeably after enabling Safe Links, Safe Attachments, and impersonation protection, enabling the SOC and messaging teams to manage higher email threat volumes without increasing operational headcounts significantly.
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 a value-for-money product.
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.
Level two support is knowledgeable and knows how the product works, which is very good.
I would give Microsoft an eight for their technical support.
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.
If there were some customizations available, I would rate its scalability as nine out of ten.
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.
It provides a high level of security and avoids phishing and scam emails.
Stronger third-party email security integration visibility and more granular policy tuning options for Safe Links, impersonation protection, and automated remediation workflows are also needed.
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.
Providing code customization would help keep pace with new vulnerabilities and threats.
The main area of improvement for Microsoft Defender Threat Intelligence is related to how information is conveyed.
From the telemetry data standpoint, I would prefer Defender data to be more open in future updates.
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.
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.
If it wasn't for that real-time threat detection on the vulnerability, I think we would not have survived the attack.
One of the best features is that it provides a certain level of customization, allowing us to set our spam confidence levels.
Our threat detection is enhanced due to the AI agents in Microsoft Defender Threat Intelligence, which helps in detecting automatically.
