Symantec Advanced Secure Gateway (ASG) combines the functionality of the Symantec ProxySG secure web gateway with the intelligence of Symantec Content Analysis to offer a single, powerful web security solution that delivers world-class threat protection. Advanced Secure Gateway is a scalable web proxy appliance designed to secure your web communications and accelerate your business applications. ProxySG and ASG draw on a unique proxy server architecture that allows organizations to effectively monitor, control, and secure traffic to ensure a safe web and cloud experience. A Symantec secure web-filtering proxy empowers you to:

  • Control web and cloud usage with fast app performance
  • Establish negative-day threat defenses
  • Implement multi-authentication realm support
  • Gain visibility into encrypted web traffic

Eliminate Your Encryption Blind Spot with Highly Secure HTTPS Inspection

Protect yourself from hidden threats with an “A” grade web security gateway appliance

Get complete visibility into SSL/TLS-encrypted web traffic with Symantec’s advanced secure web proxy and cloud security solutions. Academic researchers and internet giants such as Google, Mozilla and others scrutinized Secure Web Gateways, Next-Generation Firewalls and Application Delivery Controllers to see who was delivering secure interception of encrypted web traffic, without introducing new risk. Of all middleboxes in the study, only the Symantec web proxy appliance enabled inspection while preserving high security.

  • Scan SSL-encrypted traffic for viruses, worms, and Trojans, and block them at the secure web gateway
  • Prevent spyware from installing or communicating over SSL/TLS
  • Stop rogue applications (such as IM and P2P) that use SSL to subvert enterprise controls and security measures
  • Accelerate approved and safe SSL-encrypted traffic
  • Send a stream of decrypted traffic to third-party logging systems for analysis, archiving and forensics

Isolate Potentially Risky Traffic by Preventing Malware and Phishing Threats, While Allowing Broad Web Access

Protect your users from threats targeting web browsers

Symantec Web Isolation prevents websites from delivering zero-day malware, protects users’ devices by executing web sessions away from endpoints, and safely sends rendering information to the browser. Integration with Symantec Secure Web Gateways such as ProxySG and Advanced Secure Gateway (ASG) enables policy-based traffic isolation for uncategorized sites and for URLs with suspicious or potentially unsafe risk profiles. Specifically, this means:

  • Tight integration with Symantec Secure Web Gateways (ProxySG, ASG, and Web Security Service)
  • Patented approach that prevents any website code from executing on user’s devices
  • Responsive and interactive UI for transparent and seamless user experience
  • Selective risky traffic isolation or isolation of all web traffic for privileged users such as C-level executives
  • Isolation of URLs embedded in email to block phishing attacks
