Kaspersky
Anti-Spam SDK
Used by world’s leading IT Security companies and national ISPs, Kaspersky Anti-Spam Software Development Kit (KAS SDK) is based on the latest automated Anti-Spam technologies powered by Artificial Intelligence combined with human analysis, providing supreme detection and lowest false positive rates, and ensuring instant reaction to new spam outbreaks.
Usage Scenarios
For software and hardware developers who need mail security features in their products, Kaspersky Anti-Spam SDK provides the core anti-spam functionality that can be embedded into a wider messaging, gateway or cybersecurity platform.
ISPs, Hosting Providers and Cloud Service Providers
Scalable protection for high-volume email traffic. Multithread processing, HTTP service mode and low system workload help support demanding infrastructures where throughput and stability are business-critical.
Firewall, NGFW and Gateway Vendors
The SDK adds email-borne threat detection to network security products, helping identify spam, phishing content, malicious URLs, phishing URLs and mass-mailing activity before it reaches users.
Customized Solutions
For enterprises developing customized security systems, Kaspersky Anti-Spam SDK can become a building block in larger protection workflows. Its allowlisting and denylisting options, cloud reputation checks and anti-phishing heuristics make it suitable for tailored policies and layered defenses.
Key Features of Kaspersky Anti-Spam SDK
Kaspersky Anti-Spam SDK combines automated technologies, artificial intelligence, machine learning, and expert human analysis.
High detection quality with low false positives
The engine is based on multiple detection methods rather than a single traffic or statistical analysis technique, improving resilience against new spam and phishing campaigns.
Hybrid protection architecture
Local analysis, online checks and cloud intelligence work together. Offline technologies handle message attributes, signatures, heuristics, graphical spam processing, black and white lists and anti-phishing analysis. Online and cloud technologies add DNSBL, SURBL, DMARC, URL reputation, IP reputation, reputation filtering, and machine learning models.
Fast reaction to new outbreaks
Kaspersky’s cloud infrastructure and Anti-Spam Laboratory support frequent updates to signatures, filtering rules and heuristic algorithms. This helps keep embedded protection current while reducing the maintenance burden on the partner’s engineering team.
Developer-friendly integration
The SDK includes libraries, samples and documentation, with a lightweight, flexible API intended to reduce integration time. REST-like interfaces, HTTP service mode and Milter plug-in availability give development teams several deployment options.
Broad technical compatibility
The SDK supports standard platforms and MTAs, native 64-bit operation, client/server architecture and multithread processing capable of handling hundreds of messages per thread.
Partnership support
Kaspersky provides qualified 24/7 technical support, dedicated business and technical account managers, and marketing support from evaluation to launch and ongoing lifecycle management.
Functionality
Unlike many other spam filtering technologies based on statistical and traffic analysis procedures, Kaspersky Anti-Spam technology does not rely on a single method for spam and phishing attacks detection. This combination of multiple detection methods empowers messaging systems with advanced spam protection:
AI
AI and machine learning-based cloud models
IP reputation
Completely cloud-based technology ensuring the detection of the majority of spam mail based on sender IP address, even before using more sophisticated detection techniques
IP reputationaText Signature Analysis
“Fuzzy” and words and regular expressions comparison algorithms
Linguistic heuristics
22+ categories
DNS-based methods
DNSBL, Reverse DNS Lookup, Spam URL lists, DMARC (Domain-based Message Authentication, Reporting and Conformance)
Analysis of formal message attributes
headers, sender IP analysis, etc.
Denylisting/Allowlisting
IPs, emails, phrases
Anti-phishing heuristics
for improved phishing detection
Graphical Spam Processing
A technology for blocking all types of graphical spam
