Four Engines Working In Concert
Email threats move fast and malicious files often look like normal communication. GajShield's approach combines threat intelligence, contextual analysis, pattern detection, and intelligent sandboxing — each catching threats the others miss.
|
01
GajShield Threat LabProactive virus detection and Zero-Hour Outbreak Protection — shielding enterprises in the earliest moments of malware outbreaks and as new variants emerge. Proactive virus blocking is signature-independent and effective from the moment a threat is identified. The Threat Lab maintains a database of real-time spam outbreaks compiled through consultation with global Internet Service Providers. Patterns are analysed, categorised, and cross-matched using algorithms optimised for detecting repeating patterns and their sources. |
02
Contextual Intelligence EngineGoes beyond traditional context to create deep context for the mail application. Analyses usage and creates context by deep-diving into granular details: sender address, recipient, subject, mail content, attachments, signature — for better, more informed security with advanced visibility.

03
Recurrent Pattern DetectionAt the heart of GajShield's Mail Security is a powerful spam engine that identifies spam patterns regardless of content, format, or language. By immediately detecting new attack patterns and maintaining a database of spam outbreaks, the RPD engine identifies the quantity and speed of spam distribution — catching outbreaks before signatures are available. |
04
Network SandboxAn intelligent sandbox with anti-evasion capability — protection against malware that understands and detects virtual environments. Sandboxes various file types and embedded URLs, inspecting content that traditional signature-based antivirus cannot identify as malicious, and categorising it accordingly. |
