ZeroPath vs Semgrep: Which Code Security Platform Should You Choose? (June 2026)

Pattern-matching SAST made sense when catching known vulnerability shapes was enough. Now your codebase has authentication flows that span multiple services, business logic that doesn't fit a pattern, and a backlog of security findings you don't trust enough to act on. Some tools layer AI reasoning onto rule engines to reduce noise, but the rules still limit what can be detected. ZeroPath's AI traces what actually runs without that limitation, and the difference shows up in false positive rates, coverage, and whether fixes ever make it into a PR.

TLDR:

  • Semgrep relies on YAML rules to flag code patterns, but it misses business logic flaws that don't fit known shapes.
  • ZeroPath's AI traces data flow and validates exploit paths before surfacing findings, cutting false positives by up to 75%.
  • ZeroPath finds up to 2x more real vulnerabilities and generates verified fixes directly in PRs within a minute.
  • Semgrep demands ongoing rule authoring and maintenance; ZeroPath requires zero configuration to start scanning.
  • ZeroPath covers SAST, SCA, secrets, and IaC in one scan, with AI validation at every stage.

What is Semgrep?

Semgrep is a static analysis tool built around pattern matching. You write rules in a YAML-based syntax that mirrors the structure of the code you're targeting, and Semgrep flags any code matching those patterns across its supported languages. Developers can define custom rules to catch vulnerabilities specific to their codebase.

The newer Semgrep Multimodal layers AI reasoning on top of rule-based foundations for detection, triage, and remediation. Semgrep's published metrics report that most customers see an approximately 60% reduction in their findings backlog from Autotriage, the platform's AI-powered triage layer, on initial use.

The base Semgrep Code engine is still rule-driven. Multimodal adds a separate AI-powered detection scan that can catch some business logic flaws, like broken authorization and IDORs, but it runs as an add-on to the rule-based foundation. Multimodal doesn't write those rules for you; your team still selects, authors, and maintains them. General SAST coverage still depends on the quality and completeness of your rules, a real constraint for the broad class of vulnerabilities that don't match any pattern your rules describe.

What is ZeroPath?

ZeroPath is an AI-native application security platform: it reads code to map data flows from source to sink, infers sources and sinks from code context without requiring predefined rules, and runs a multi-stage validation pipeline before surfacing any findings. Where legacy SAST tools generate waves of findings your team has to manually triage, ZeroPath validates results before surfacing them, cutting false positives by up to 75% and finding up to 2x more real vulnerabilities.

With no onboarding or configuration required to get started, ZeroPath covers SAST (including business logic flaws, authentication bypass, and race conditions that pattern-based tools miss), SCA, secrets detection, and IaC in a single scan. Results land directly in pull requests in under a minute. Aptos Labs went from first call to production scanning in under 2 days.

ZeroPath also goes further than detection. When it finds a vulnerability, it generates a fix and verifies it, so your engineers get an actionable patch alongside the finding: a real solution, not another ticket to investigate. That end-to-end path from finding to fix is what separates it from tools that stop at the findings list.

Detection capabilities and coverage

Semgrep's detection engine is built on pattern matching: rules written in YAML describe code structures, and the scanner flags anything that matches. This works well for known vulnerability classes like SQL injection or hardcoded secrets, but it struggles with bugs that require understanding how data flows across files, modules, or services.

ZeroPath's AI reads code the way a security engineer would, tracing data from source to sink, reasoning about control flow, and catching business logic flaws that no pattern can describe. While Semgrep requires a rule for a specific vulnerability shape, ZeroPath finds novel variants and context-dependent bugs without such a rule.

Coverage that goes beyond patterns

Both tools cover common vulnerability categories, but the gap widens as complexity increases:

  • Semgrep handles single-file and cross-function analysis well, with community and proprietary rulesets covering OWASP Top 10 categories.
  • ZeroPath covers the same surface area and extends into multi-service data flows, authentication logic flaws, and race conditions that require reasoning about program state beyond simple syntax.
  • Semgrep's Pro engine adds cross-file taint tracking, but it still depends on rules to define what counts as a source or sink. ZeroPath infers these from the code itself: the AI reads HTTP handlers, user input entry points, and data exits, like database calls or command execution, to build a source-to-sink map without any rules defining them.

The practical consequence: ZeroPath finds up to 2x more real vulnerabilities and up to 75% fewer false positives, thanks to its two-stage AI pipeline that checks exploitability and code flow before any finding reaches your team. At Commenda, that process surfaced 4x more real vulnerabilities than Snyk.

False positive management and accuracy

False positives are where rule-based SAST tools lose developer trust the fastest. Semgrep's pattern-matching engine flags anything that structurally resembles a vulnerability, regardless of whether real execution paths lead there. Teams routinely report spending more time triaging noise than fixing actual bugs.

ZeroPath validates every finding before it surfaces through two distinct pipeline stages: an initial AI pass that reviews exploitability, code flow, and context to filter non-exploitable results. A secondary validation pass reviews all remaining findings before recording them. That two-stage process independently produces up to 75% fewer false positives than traditional SAST tools, so your engineers spend time on confirmed vulnerabilities, not chasing alerts that lead nowhere.

Commenda's code reviews had been catching a fraction of what ZeroPath found. Systematic scanning surfaced 4x more real vulnerabilities with far less noise. That signal-to-noise ratio is what separates a platform your team acts on from one they stop opening.

Rule management and maintenance

Semgrep's rule-based engine is only as good as the rules feeding it. Out of the box, you get a solid registry of community and Pro rules, but keeping those rules current, tuned, and relevant to your codebase is ongoing work that falls squarely on your team. Writing custom Semgrep rules requires learning its pattern syntax and metavariable system. That's manageable for a seasoned AppSec engineer, but it adds friction, and rules still need versioning, testing, and periodic auditing as your codebase evolves.

ZeroPath has no rules to author or maintain. Its AI reads code contextually instead of matching patterns, and coverage expands automatically when ZeroPath ships model improvements; no reconfiguration or re-scanning is required by your team.

The difference in maintenance burden is most evident at scale. The more your codebase relies on internal frameworks or custom authentication flows, the more custom rules Semgrep demands. ZeroPath's coverage generalizes across codebases without per-repo configuration.

Remediation and developer experience

Findings mean little without fixes. ZeroPath goes beyond detection by generating validated, context-aware remediations directly in pull requests, so your engineers see a proposed fix alongside the vulnerability report, all within their workflow.

Semgrep can suggest fixes through its autofix feature, but these are pattern-based rewrites tied to the same rule that flagged the issue. They work well for simple, syntactically predictable problems, but fall short on business logic flaws or vulnerabilities that require understanding cross-file context.

ZeroPath's AI traces the full source-to-sink path before generating a fix, so the remediation reflects how the code actually behaves: the full context, not what the flagged line looks like in isolation. Fixes land in the PR in under a minute, with no additional configuration required from the engineering team.

The developer experience gap is most visible in alert volume. Semgrep's rule-based engine produces findings at scale, and without a validation layer, your team ends up triaging a mix of real issues and noise. Semgrep Multimodal adds AI reasoning on top of that rule engine, but it does not add an independent validation layer. Findings still flow through without the two-stage exploit-path check ZeroPath runs before surfacing anything. ZeroPath's AI validation reduces false positives by up to 75%, so the alerts your team sees are worth acting on.

Setup time is another practical distinction. Semgrep requires rule selection, tuning, and ongoing maintenance as codebases evolve. ZeroPath is production-ready in under 2 days, as Aptos Labs confirmed when they went from first call to live scanning in that window.

Why ZeroPath is the better choice

ZeroPath takes a different approach to application security than Semgrep's rule-based engine. Where Semgrep flags patterns and hands findings to your team to sort through, ZeroPath's AI reads code the way a security engineer would: tracing data flows, following execution paths, and reasoning about whether a vulnerability is actually reachable and exploitable before surfacing it.

That distinction has measurable consequences. ZeroPath finds up to 2x more vulnerabilities than traditional SAST tools while producing up to 75% fewer false positives. Your team spends time on bugs that matter, not chasing pattern-match noise.

Here are a few areas where this shows up concretely:

  • Business logic vulnerabilities can't be caught by pattern matching. They require reasoning about application behavior and program semantics, beyond code syntax alone. ZeroPath surfaces auth flaws, privilege escalation paths, and logic errors that Semgrep's rules miss entirely.
  • Fixes ship in the PR, not in a backlog. ZeroPath posts verified, context-aware fixes directly into pull requests, typically within a minute of a scan completing. Semgrep surfaces findings; remediation is left to your engineers.
  • Zero configuration required. ZeroPath connects to your repo and starts scanning without custom rule authoring or tuning. Semgrep's coverage depends heavily on which rulesets you've written or maintained.
  • Secrets, SCA, and IaC are covered in the same scan. Semgrep splits these into separate products: Semgrep Secrets for credential detection, Semgrep Supply Chain for dependency vulnerabilities, and IaC coverage, which relies on community rules instead of a dedicated scanner.

For teams that have outgrown Semgrep's rule-based model and need security that keeps pace with their code, ZeroPath is the practical next step.

Final thoughts on ZeroPath vs. Semgrep

Semgrep's rule engine is solid for known vulnerability patterns, but it stops at detection, leaving the heavy lifting to your team. ZeroPath reads your code like a security engineer would, traces real exploit paths, and ships fixes in under a minute. If you're tired of managing rulesets and triaging noise, run a scan with ZeroPath and compare what it catches.
