Executive SummaryUpdated on Jan 25, 2026
Symantec Endpoint Security and Microsoft Defender for Business are leading contenders in endpoint protection. Microsoft Defender appears to have an edge due to its seamless integration within its ecosystem and cost-effectiveness for existing Microsoft users.
Features: Symantec Endpoint Security offers comprehensive protection with features like antivirus, anti-spyware, and intrusion prevention systems. It supports application and device control across multiple operating systems, ensuring versatility. Microsoft Defender for Business excels in integration with Microsoft products, offering enhanced threat detection, response capabilities, and extensive security features for identity, application, and endpoint protection.
Room for Improvement: Symantec potentially suffers from high resource consumption and complex management, with criticisms on its virus detection efficiency for zero-day threats. Modern features like advanced threat detection are not included in the base pricing. Microsoft Defender for Business could benefit from improved threat protection precision and better integration with non-Microsoft ecosystems, alongside interface simplification to reduce manual management.
Ease of Deployment and Customer Service: Symantec is typically deployed on-premises, leading to complex setups compared to Microsoft Defender for Business, which offers flexible cloud and hybrid deployment options. While both offer commendable customer support, Symantec's service consistency is questioned post-Broadcom acquisition. Microsoft’s deep integration within its ecosystem provides streamlined support for its user base.
Pricing and ROI: Symantec Endpoint Security is generally more expensive but considered valuable for reducing malware incidents, offering varied licensing models. However, it faces competition from less costly alternatives. Microsoft Defender for Business is often included with Microsoft 365 subscriptions, providing a cost-effective option for existing users. Nevertheless, its standalone costs can be higher, albeit justified by its comprehensive ecosystem integration and capabilities.
