Stop spam, viruses and data leaks. Combining anti-spam, anti-virus and anti-phishing capabilities with content filtering and outbound email protection, the Dell™ SonicWALL™ Email Security Appliance (ESA) 4300 provides comprehensive, effective and scalable email security for organizations with up to 5,000 employees.
Effective defense against email attacks.
Leverage multiple, established and patented email virus and spam protection techniques with Dell™ SonicWALL™ Email Security Appliance (ESA) 4300 and software, and stop attacks with over 99 percent effectiveness. Check email sender IP reputations, as well as the reputation of content, structure, links, images and attachments. Ensure sender validation, and protect against directory harvest attacks (DHAs) and denial of service (DoS) attacks. Protect against known threats, and uncover new ones with adversarial Bayesian filtering, image analysis and gibberish detection.
Real-time identification of threats in real time.
Receive real-time threat information from the SonicWALL Global Response Intelligent Defense (GRID) Network™ and the latest anti-virus and anti-spyware protection with SonicWALL GRID Anti-Virus. The GRID network collects and analyzes information from industry threat lists, performs rigorous testing and evaluation of millions of emails every day, and establishes reputation scores for senders and content, identifying new threats in real time. Add optional multilayer anti-virus protection, including an additional layer of anti-virus protection with McAfee® anti-virus signatures. Safeguard your network from the time a new virus outbreak occurs until the time an anti-virus signature update is available, using the predictive technology of SonicWALL Time Zero Virus Protection.
Scalable protection for any environment.
You can deploy the ESA 4300 as a high-performance, hardened appliance, software for your existing infrastructure, or as a virtual appliance. Start with a single system, and easily add capacity, moving to a fail-over-enabled, split-mode architecture as your business grows. Leverage multi-tenancy support to delegate sub-administrators to manage settings at multiple organizational units (such as enterprise divisions or MSP customers) within a single SonicWALL Email Security deployment, and enable each to configure its own users, policy rules, junk boxes and other functionalities.
Seamless management and control.
Manage task delegation, intelligent automation, and robust reporting, and automatically administer email addresses, user groups and accounts, with seamless integration across multiple LDAP servers. Delegate spam management to end users while retaining full control with the downloadable Junk Button for Outlook® plug-in. Locate any email in seconds with the Rapid Message Search Engine. Easily customize reports on attack types, solutions effectiveness and built-in performance monitoring.
Powerful virus and spam protection.
Ensure that your email is safe, productive and cost-effective, and meet email compliance mandates, with the SonicWALL ESA 4300 appliance, software, virtual appliances and services. Deliver an effective email virus and spam blocker for organizations with a few employees or 100,000.
Robust policy management.
Monitor, identify and report on email that violates corporate compliance, regulatory compliance or data loss guidelines with compliance policy management. Route policy-based emails for approval, encryption and archiving. Ensure the secure exchange of email containing sensitive customer data or confidential information with email encryption.
Advanced email encryption.
Integrated email encryption policies may be configured to scan outbound email content and attachments for sensitive data. When sensitive data is detected, the email is encrypted for secure email exchange with customers and partners. Encrypted email can be tracked to confirm the time of receipt and time opened. Intuitive for the recipient, a notification email is delivered to the recipient’s inbox with instructions to simply log into a secure portal to read or securely download the email. The service is cloud-based so, unlike competitive solutions, no additional client software is necessary and the encrypted email may be accessed and read from mobile devices or laptops.
