Checkmarx Fusion
Most scanners force a choice: catch more, or get bogged down in noise or miss things that matter. Checkmarx Fusion achieves both, fusing deterministic precision with frontier AI coverage into one clean, verified result.
More Fidelity. Less Noise. Most Comprehensive.
Built to Cover Everything.
Checkmarx Fusion delivers the highest fidelity and broadest coverage in enterprise AI scanning, at a cost that is known from the start.
Find the Unfindable
Several curated AI models reason about your code simultaneously, each approaching it differently. No single model sees every blind spot. Together they surface vulnerabilities with no known rule and no prior CVE. Model-agnostic by design: no frontier model is assumed best, and no customer is locked to one. Model optionality lets users choose high or low cost models, according to their needs.
Choose Your Coverage Level
Turn Checkmarx Fusion on or off at the global level. Teams that need the highest fidelity enable it; teams on standard scanning are unaffected. One setting, no workflow disruption.
Scan Multiple Projects at Once
Run Checkmarx Fusion across your entire project portfolio in a single operation. Results stay organized by project, comparable across codebases, and visible in one place. Incremental scanning means faster and faster scans over time.
View Results in ASPM
Checkmarx Fusion findings land directly in Checkmarx One, where our Risk Orchestration’s context-aware correlation scores and prioritizes them alongside every other signal in your portfolio. Scored, prioritized, and ready to act on, not a separate report to reconcile.
One Architecture, Every Scan Type
Checkmarx Fusion starts with SAST and extends across Secrets Detection, IaC, API Security, and DAST on the same model.
• SAST: Available now
• Secrets Detection: COMING SOON
• Infrastructure as Code (IaC): COMING SOON
• API Security: COMING SOON
The Scanner Trade-Off Ends Here
More of the risk that’s real. Less of what isn’t. And an architecture that doesn’t make you trade one for the other.
Rules-based SAST can’t catch vulnerabilities that require reasoning about how code will behave. Rules only cover what code contains, not how it executes. AI-generated code makes this gap worse.
Coverage that keeps pace with AI
The AI-based engine extends coverage to every language your AI assistant writes in, including the ones your rules-based tool has never seen. If it ships, it gets scanned.
The window between disclosure and exploitation has collapsed.
No grace period, no gaps
Anthropic’s own research found a working exploit generated within an hour of a patch shipping. A missed vulnerability isn’t a near-miss anymore. It’s an active risk. Detection has to be faster than attackers.
Standalone AI scanning burns through tokens at enterprise-killing costs, and still can’t guarantee the same answer twice.
Consistent results at a predictable cost
Checkmarx Fusion runs a bounded, curated set of Checkmarx-validated models rather than open-ended frontier API calls. Security teams get consistent results at a predictable and optimized cost, not a token bill that compounds across every commit.
More Signal. Less Noise.
0.74 F1 in SAST. Three times the query-based baseline.
The jump from 0.64 isn’t marginal. It’s catching the flaw that causes a breach.
What Checkmarx Fusion Gets You
The highest-fidelity scanning architecture available. A defensible risk picture your team can act on, and your CISO can take to the board.
Best of Both Worlds
Deterministic precision and AI coverage, not a compromise between them. Full strength from both, in one verified result.
The Same Answer Every Time
Scan it twice, get the same result. Standalone AI scanning can’t promise that. Checkmarx Fusion can.
Fewer False Positives
The Findings Analysis Engine strips noise before it reaches your team. Real findings, not alert triage.
Built for Enterprise Scale
Incremental scanning means only new and changed code gets re-scanned. Faster scans, fewer delays, and performance that improves the larger your codebase gets.
Predictable Cost
A bounded, curated set of Checkmarx-validated models. Higher or lower cost. You choose. Consistent results at a cost that doesn’t compound. The audit trail does.
The Full Platform Picture
Findings flow into Checkmarx One, where Risk Orchestration prioritizes by business risk, Triage Assist routes for action, and Remediation Assist turns findings into merge-ready fixes. One platform, nothing siloed.
