Embedded NGX includes VStream Antivirus, an embedded stream-based antivirus engine that supports efficient antivirus stateful scanning at the kernel level.
What is VStream Antivirus? VStream Antivirus, a gateway-based antivirus solution, blocks security threats before they ever reach your network. The virus signatures are automatically updated, keeping the security up-to-date with no need for user or network administrator intervention.
Although it can be used alone, VStream Antivirus is especially suitable as a second layer of antivirus, complementing the capabilities and addressing the weaknesses of desktop antivirus software.
What are the advantages of VStream Antivirus over traditional gateway-based antivirus solutions? Based on Check Point Stateful Inspection and Application Intelligence technologies, VStream Antivirus offers several advantages over traditional proxy-based gateway antivirus solutions:
| Lightweight Streaming | Traditional proxy-based antivirus solutions must download the entire file into intermediate storage before virus scanning can begin. This means high latency, limited support for large files, and poor scalability to large numbers of concurrent connections. Instead of relying on intermediate storage, VStream Antivirus technology enables stateful scanning of files on the fly. This means minimal added latency and support for unlimited file sizes. By taking great care to store only minimal state information per connection, VStream Antivirus can scan thousands of concurrent connections. | | Comprehensive Protocol Support | VStream offers comprehensive protocol support, including HTTP, FTP, POP3, SMTP, and IMAP, as well as arbitrary, user-defined TCP and UDP ports. | | Granular Scanning Policy | A customizable scanning policy allows specifying with very fine granularity exactly which connections should be scanned for viruses. | | On-the-fly Decompression | VStream supports on-the-fly, real-time decompression and scanning of ZIP, TAR, and GZ archive files. Archive files can be scanned with no file size limitation and with support for nested archive files. |
