Kaspersky Anti-Spam Software Development Kit 5.0

Kaspersky Anti-Spam Software Development Kit (KAS SDK) is the combination of the latest automated Anti-Spam technologies, together with human analysis providing supreme protection against spam and phishing and ensuring instant reaction to new spam outbreaks.

Thanks to Kaspersky Anti-Spam SDK’s architectural flexibility, exceptional accuracy and impressive stability, solutions based on it meet the requirements of all types of customers, from SMBs to large enterprises and service providers.

The Hybrid approach allows Kaspersky Lab to use cloud-based intelligence and information distribution, complementing the advanced protection technologies used in Kaspersky Anti-Spam Engine. Thanks to hundreds of millions of users in Kaspersky Security Network, any new spam message becomes tagged as such as a matter of seconds, and a corresponding signature gets added to the anti-spam bases with the nearest update. A powerful anti-spam engine based upon dozens of detection methods adds smarts to the cloud mind’s power and guaranties unparalleled detection rates for spam and phishing attacks with minimal false alarms.
