  • Integration with advanced threat protections
  • Control over web and cloud usage
  • Accelerated cloud app performance


Negative Day Threat Defence

The ProxySG provides on-demand cloud intelligence and real-time web content ratings to ensure your enterprise is protected from the latest threats. Blue Coat’s cloud-based Global Intelligence Network feeds valuable, up-to-date information on the latest risks to the analytics engines to accelerate responses to web-based threats. A billion new web requests a day, from more than 15,000 enterprise customers and millions of end-users, are collected and analysed to keep the ProxySG current; as a result, Blue Coat typically blocks over four million previously unseen or uncategorised threats per day. New defences can also be seamlessly added to the Global Intelligence Network to scale the depth of protection, as needed.

Strong User Authentication

ProxySG has the broadest support for authentication vendors in the industry, providing the ability to easily integrate new users and groups – even those using completely different authentication technologies. The ProxySG supports multiple realms, and allows policies to query multiple realms sequentially as necessary to find a user, or default to a guest authentication scheme when a user cannot be found.

Visibility into Encrypted Traffic

The ProxySG has an SSL Proxy that allows for visibility into SSL traffic, so the ProxySG can securely send attachments and content for inspection services. Encrypted Tap, a licensable feature, builds on the SSL Proxy capabilities to send a stream of decrypted content to third-party systems for additional analysis, archiving, and forensics. Together, they eliminate SSL blind spots, giving you complete visibility and control over SSL-encrypted traffic to stop rogue applications, malware and cyberattacks from using SSL to hide their activities.

Integration with the Latest Advanced Threat Protections Across the Industry

ProxySG works seamlessly with best-of-breed technologies, including anti-malware, anti-virus (AV), blacklist and whitelist engines from a variety of vendors, as well as the static code analysis and sandbox brokering found in Symantec Content Analysis. The ProxySG can securely enable data loss prevention with certified DLP partners, via S-ICAP or standard ICAP.

Control Over Web and Cloud Usage

ProxySG gives you control over your sensitive content. ProxySG enables you to identify cloud apps and reduce the risks posed by non-sanctioned, “shadow IT” – 80% of employees use software as a service (SaaS) applications for work without their employer’s knowledge. The Web Application Policy Engine provides granular visibility and control over all the web applications in use in your environment.

Accelerated Cloud App Performance

The ProxySG provides content caching and traffic optimization to ensure your critical cloud apps are there when your users need them. It offers advanced bandwidth management, with streaming media splitting and method level controls, per protocol, to help you optimize the overall performance, efficiency and capacity of your bandwidth investments.

Hybrid Delivery Model

Symantec’s industry-leading web protection is available as an appliance (ProxySG), virtual appliance (SWG VA), and cloud service (Web Security Service) – meeting the unique security needs of any organisation whether on-premises, in the cloud, or hybrid deployment.

Unmatched Performance and Reliability

The ProxySG provides up to 1Gbps throughput for high availability deployments. The hardware platforms and operating system (SGOS) were built for fast, efficient web object processing, running year after year at performance levels beyond the competition. Secure and small in design, the ProxySG rarely needs attention or patches. Health checks and monitoring provide administrator awareness, and Symantec Management Center enables centralised device, license and policy management.

Scalability and Lower TCO

ProxySG delivers a lower TCO through performance innovations that require less hardware, rack space and power than alternative solutions. Available reporting scales for visibility of all secure web gateway and remote users, with custom dashboards and reports on a single server optimised for up to 20 billion log lines.
