Semgrep has launched Semgrep Multimodal, a code security system combining AI reasoning with rule-based analysis for vulnerability detection, triage and remediation. The system finds up to eight times more true positives whilst cutting noise by 50% compared to foundation models alone, and has discovered dozens of zero-day vulnerabilities at customer sites. Built on Semgrep Workflows, the framework enables security teams to automate processes using deterministic tools and AI. Traditional rule-based scanners excel at catching known vulnerabilities but struggle with business logic flaws, whilst LLMs alone produce high false positive rates. Semgrep Multimodal addresses both dimensions by pairing precise programme analysis with LLM reasoning. Semgrep Multimodal is available today, with custom workflows accessible via private beta. Companies including Snowflake, Figma and Dropbox use Semgrep's platform.

Semgrep, a leading application security platform, has secured $100 million in Series D funding, led by Menlo Ventures with participation from existing
