In today's era of widespread digital office, enterprise email, as the core communication carrier, carries key functions such as business negotiations, data transmission, and confidentiality retention. Its security performance directly affects the integrity and confidentiality of enterprise information assets. Tencent Enterprise Email relies on Tencent's 20-year security capabilities to build a three-dimensional protection system covering the entire lifecycle of emails. It integrates threat intelligence driven, AI intelligent recognition, and multi-dimensional control strategies to form a closed-loop security mechanism of "pre defense, mid interception, and post traceability", providing high-strength protection for enterprise communication security through WeChat Pay at the same level.

As the first level of protection for login security, Tencent Enterprise Email adopts a dynamic risk control mechanism. Based on a 200+dimensional feature model, a user behavior profile is constructed, and a dynamic evaluation system is established by combining five core dimensions such as geographic location, behavior habits, and reputation rating to accurately identify abnormal login risks. When suspicious behaviors such as non working IP usage, non working time login, and high-frequency password attempts are detected, the system will automatically trigger secondary verification, supporting multiple verification methods such as WeChat QR code scanning and OTP dynamic passwords, and can also intercept risky IP access; Administrators can also set detailed control rules such as geofencing, device fingerprint binding, and login time period restrictions to further compress the risk attack surface and prevent account theft risks from the source.

In terms of email content protection, Tencent Enterprise Email relies on the billions of sample data from Tencent Security Threat Intelligence Center to create intelligent anti spam, anti-virus, and anti leakage triple protection capabilities. Among them, the AI anti spam system can accurately identify variant spam emails through deep learning semantic analysis technology, with a spam interception rate of up to 98.7% and a marketing email misjudgment rate of less than 0.01%. It has accumulated dozens of national patents related to anti spam; For advanced threats such as APT attacks and phishing emails, the system's interception accuracy rate is 99.6%, which can identify malicious attachments and phishing links in real time, detect sensitive information (ID number, bank card information, etc.) in emails, trigger secondary verification or block outgoing, and prevent norm data leakage. At the same time, a third-party professional antivirus engine updates the virus database every 5 minutes, with a virus interception rate of over 99.8%, providing comprehensive protection against malicious code intrusion.

Sending behavior control and collaborative defense further strengthen the security defense line. The system supports setting a threshold for email sending volume. When the hourly sending volume suddenly increases by 500% or the daily sending exceeds the limit, secondary verification will be forcibly enabled and an alert will be pushed to avoid mass sending of spam or leakage of enterprise secrets after account theft; At the same time, quotas can be distributed and controlled by department and job level, balancing office efficiency and security risks. In addition, Tencent Enterprise Email and Enterprise WeChat share a global threat intelligence database, real-time synchronization of risk information, and interoperability of risk data such as malicious IPs and illegal accounts to achieve collaborative defense; Employees can scan the code to log in to their email through enterprise WeChat to achieve unified identity authentication. After the enterprise WeChat account of the departing employee is frozen, the email account will be synchronously invalidated, forming a security control system for the entire lifecycle of the account.

In terms of compliance and data retention, Tencent Enterprise Email has passed multiple international and domestic authoritative certifications such as the National Information Security Level Protection Level 3 Certification and ISO/IEC27001 Information Security Management System Certification, and has a comprehensive data backup and archiving mechanism. Email data is stored redundantly in a distributed manner and backed up on multiple servers. If an email is accidentally deleted within 7 days, it can be fully restored with zero loss rate guarantee; The cloud email archiving function can meet compliance requirements such as the Cybersecurity Law and the Personal Information Protection Law, ensuring that important emails can be traced and audited, and providing technical support for enterprise compliance operations.
