To address shifting challenges and stay aligned with a faster pace of application development, Prevoty has architected a solution based on the principles of LANGSEC and delivered as a Runtime Application Self-Protection (RASP) tool. 

This innovative model presents a significant change in the way application security is delivered to the enterprise.

LANGSEC is the formal process of understanding how data such as content payloads, database queries, operating system commands and more will execute in an environment. The technique is akin to a real-time compiler for data input that is built from the grammar that comprises programming languages, browser rendering engines, database query engines, and operating systems and uses this contextual knowledge to detect and neutralize sophisticated attacks during execution.

LANGSEC Enterprise protection

Prevoty is the first to go to market with an effective runtime solution that utilizes the LANGSEC approach, with its own lexical analyzers, validators and parsers to effectively analyze and identify malicious behavior. Prevoty’s RASP implementation performs the most sophisticated form of application security instrumentation, understanding what content is going to do before code execution and neutralizing threats like cross-site scripting (XSS), SQL injection (SQLi), and cross-site request forgery (CSRF) without using unwieldy patterns or heuristics.

LANGSEC is a detection mechanism that is faster, simpler, and more accurate than traditional methods using signatures, heuristics & data flow analysis.

The Benefits of LANGSEC


  • 30x faster than traditional methodologies
  • Reduced CPU and memory consumption


  • No false positives or false negatives
  • Contextual payload analysis blocks fuzzing
  • Higher correct rate than scanners or tests


  • Low maintenance (no signatures or patterns)
  • Zero tuning or learning
  • Quick custom policies (domain and application-specific controls)
  • Reduces WAF upkeep
