According to G2 reviews of Microsoft Defender for Office 365, the pricing structure suits a wide range of organizations, though fit varies by tier. Plan 1 at $2.00 per month is well-suited for small businesses and mid-market organizations already using Microsoft 365 that need foundational email and collaboration security without complex configurations. Plan 2 at $5.00 per month is best suited for enterprise organizations and managed service providers, particularly in IT services, financial services, and healthcare, where advanced threat hunting, automated response, and attack simulation training are essential. G2 reviewers in MSP environments specifically highlight Plan 2's Threat Explorer and XDR capabilities as critical for managing multiple client tenants effectively. ### What are the key differences between the free and paid versions of Microsoft Defender for Office 365? Microsoft Defender for Office 365 does not offer a free standalone version. According to G2's pricing data for Microsoft Defender for Office 365, the entry-level Plan 1 at $2.00 per month covers anti-phishing, anti-malware, spam protection, Safe Links, Safe Attachments, and protection across Teams, SharePoint, and OneDrive. Microsoft Defender for Office 365's Plan 2 at $5.00 per month adds advanced threat hunting via Threat Explorer, automated investigation and response, attack simulation training, and full Microsoft 365 Defender XDR capabilities. G2 reviewers note that Plan 1 lacks critical features like Threat Explorer and attack simulators, which are key drivers for upgrading to Plan 2. ### Is Microsoft Defender for Office 365 considered good value for its pricing? G2 reviewers of Microsoft Defender for Office 365 consistently rate it highly, with many praising its seamless integration with the Microsoft 365 ecosystem, advanced threat protection, and automated investigation capabilities. However, cost concerns appear frequently across G2 reviews, particularly from small businesses and mid-market users who find the subscription pricing somewhat expensive compared to alternatives. Reviewers in enterprise segments tend to view the pricing as justified given the robust phishing, malware, and BEC protection it delivers. G2 users also note that advanced features like threat hunting and attack simulation training require the pricier Plan 2, which can strain smaller budgets. Overall, organizations already invested in Microsoft 365 generally consider it a worthwhile security investment. ## Top-Rated Alternatives [ ![Proofpoint Core Email Protection](https://images.g2crowd.com/uploads/product/hd_favicon/8adf2eedd5616a9f5e200c4520f6d30d/proofpoint-core-email-protection.svg "Proofpoint Core Email Protection") Proofpoint Core Email Protection 4.6/5(601) ](https://www.g2.com/products/proofpoint-core-email-protection/reviews) [ ![SpamTitan Email Security](https://images.g2crowd.com/uploads/product/hd_favicon/1553620140/spamtitan-email-security.svg "SpamTitan Email Security") SpamTitan Email Security 4.5/5(199) ](https://www.g2.com/products/spamtitan-email-security/reviews) [ ![Symantec Email Security.Cloud](https://images.g2crowd.com/uploads/product/hd_favicon/7e0271a147c13a70a6587f9586b454a0/symantec-email-security-cloud.png "Symantec Email Security.Cloud") Symantec Email Security.Cloud 4.1/5(66) ](https://www.g2.com/products/symantec-email-security-cloud/reviews) [ View All Alternatives ](https://www.g2.com/products/microsoft-microsoft-defender-for-office-365/competitors/alternatives) ## Microsoft Defender for Office 365 Alternatives Pricing The following is a quick overview of editions offered by other [Email Anti-spam Software](https://www.g2.com/categories/email-anti-spam) | ![Proofpoint Core Email Protection](https://images.g2crowd.com/uploads/product/image/small_square/small_square_f9b90f9d8d4e2cbdf787403ec274b32f/proofpoint-core-email-protection.jpg) [Proofpoint Core Email Protection](https://www.g2.com/products/proofpoint-core-email-protection/reviews) ##### Proofpoint Core Email Protection | Free Trial0 Mailbox Per Year | - Core Email Protection | | ![SpamTitan Email Security](https://images.g2crowd.com/uploads/product/image/small_square/small_square_b00eebb9d7957901dc4176f594f678a9/spamtitan-email-security.jpg) [SpamTitan Email Security](https://www.g2.com/products/spamtitan-email-security/reviews) ##### SpamTitan Email Security | Starting at $2.14Per Month | Book a demo today to learn more about how SpamTitan can help keep your organisation safe.

Senior Analyst Enterprise (\> 1000 emp.) 10/14/2025 More Options - "Powerful Email Security and Monitoring, but Support Needs Improvement" 4/5 What do you like best about Microsoft Defender for Office 365? We use this as an email security tool and to monitor alerts and incidents. What I appreciate most about Defender for Office 365 is its ability to display all activities, even on a small server accessed from a device that has been onboarded to Defender. Its micro-level monitoring is impressive. Managing email security is straightforward thanks to the well-organized segmentation of tabs and lists. We rely on it almost daily to handle security breach incidents, which we can resolve quickly because of the robust features it offers. As a security administrator, I find it very effective. The implementation process was simple since it was deployed over the cloud. Additionally, we were able to integrate the tool with Splunk and the Argus portal without any difficulty. Review collected by and hosted on G2.com. What do you dislike about Microsoft Defender for Office 365? The most frustrating aspect of Defender is its support team. They are slow to provide resolutions and often fail to respond to emails, which means we have to go through the trouble of following up ourselves. I have dealt with support teams from other major companies, and this is an area where Microsoft really needs to improve. There is no hotline or direct number to quickly reach the Microsoft TAC, which makes the process even more difficult. While all the other features are excellent, my main suggestion is to enhance the quality of customer support. Review collected by and hosted on G2.com. What problems is Microsoft Defender for Office 365 solving and how is that benefiting you? Our entire inbox is well protected thanks to the strong features this software offers, including quarantine and ZAP. The tool provides both pre-disaster and post-disaster solutions, allowing us to address any issues whenever they arise. It is highly responsive and reliable, and unlike many other tools on the market, it has never experienced downtime. Review collected by and hosted on G2.com.
