Fast patterns. No graph. No agent-time.
Semgrep's pattern-matching speed is impressive. But patterns match syntax — they don't understand the data flow an AI agent just introduced across three files.
What Semgrep does well
Extremely fast SAST, excellent community rule library, good custom rule authoring without a PhD, solid IDE integration, secrets detection.
But:
Rule-based, syntactic. No semantic data-flow analysis. No reachability scoring. No business-logic detection. No MCP integration. No agent-time enforcement. No AI autofix. Semgrep Supply Chain is a separate product.

Pattern-matching vs graph reasoning
Semgrep finds what matches a rule. CybeDefend understands what a rule means in the context of your specific codebase. A taint-tracking rule in Semgrep requires you to enumerate every source and sink. CybeDefend mines your codebase to build a graph of data flows and ownership — then applies rules semantically, not syntactically.
Community rules vs your own rules
Semgrep's community rule library is one of the best in the industry. CybeDefend augments universal rules with rules mined from your own codebase — patterns specific to your auth system, your data model, your business logic. These are the vulnerabilities no community rule will ever catch.
From CI scanning to agent-time interception
Semgrep's rules run in CI, after the code is written and committed. CybeDefend intercepts at the MCP layer before the AI agent completes a write. The gap between those two moments — one sprint's worth of AI-generated code — is where logic bypasses and missing auth checks are born and survive.

Frequently Asked Questions
Does CybeDefend support custom rules like Semgrep?
Yes. CybeDefend allows custom rule authoring in addition to its auto-mined rules. Unlike Semgrep's pattern-based rules, CybeDefend rules can reference graph relationships (data flow, call graph, ownership) not just syntactic patterns.
Can CybeDefend be used alongside Semgrep?
Yes. Semgrep in CI + CybeDefend at agent-time is a valid setup. In practice, CybeDefend's agent-time enforcement catches the majority of issues before the Semgrep CI scan runs.
How does false-positive rate compare?
Semgrep's false-positive rate depends heavily on the rules used. Community rules are generally low-noise. CybeDefend's graph-based analysis adds reachability context, which further reduces false positives by only surfacing findings where the vulnerable path is actually exercised.
