Beyond Traditional Rule-Based Detection
Semgrep focuses on rule-based pattern detection. Precogs goes further with contextual analysis, reduced false positives, and actionable remediation across code, secrets, and compliance risks.

Key Differentiators: Precogs AI vs Semgrep
See how Precogs’ AI-native, full-stack security delivers deeper coverage, less noise, and faster remediation than traditional tools.
Agentic AI - Find, Fix, Ship
Semgrep finds issues with precision - but fixing is manual. Precogs runs an agentic AI workflow: it autonomously detects, triages by real-world exploitability, generates the actual code fix, and delivers it as a pull request. No researching remediation, no writing patches, no security backlog. Your developers review and merge - that’s it.
PII, Secrets & Pre-LLM Sanitization
Semgrep has secrets detection but no PII scanning at all. Precogs includes advanced PII detection (99.2% precision across 30+ data types - credit cards, SSNs, NHS numbers, IBANs, passport numbers), multi-layer secrets scanning, AND Pre-LLM Sanitization - which strips all sensitive data from your code before it reaches any AI model. Your customer data and IP never leave your environment.
AI Intelligence vs Pattern Matching - Zero-Day Detection
Semgrep is the best pattern-matching SAST tool on the market. But pattern matching only finds vulnerabilities that match pre-defined rules. If a rule hasn’t been written for a specific vulnerability, Semgrep won’t catch it. Precogs’s multi-model AI ensemble understands code context and can detect novel vulnerability patterns - including zero-days - that no rule has been written for. This is the fundamental difference between rules and intelligence.
