Summary: The control set — IDE-time scanning, SAST/SCA/secrets in CI, reachability-based prioritisation, and governance over which assistants are allowed and what they may touch.

The two jobs, which buyers conflate
Orca’s clearest contribution:
Securing AI-generated code means “treating the output of an assistant as untrusted input.”
Using AI to secure code means “the tool itself runs models to analyze code, explain a vulnerability, and write the patch. Here the AI is the defender.”
“The two meanings point in opposite directions, and the best solutions close both.”
This is structurally the same split as AI incident response, where “AI-driven IR” also means both using AI to respond and responding to attacks on AI. Two domains, same terminological collision — worth recognising because in both cases buying for one meaning leaves the other uncovered.
Core capabilities
From Orca’s breakdown, with the failure mode each has:
| Capability | What it does |
|---|---|
| AI-powered SAST | Finds logic flaws that “don’t trip a linter because the code is syntactically correct” |
| SCA / dependency scanning | Catches stale, vulnerable and non-existent packages — see slopsquatting |
| Secrets detection | Finds hardcoded credentials, which models reproduce from training data |
| PR-time review | The checkpoint that replaces the eroded human one |
| AI-driven remediation | Proposes the patch, not just the finding |
| Reachability and runtime context | Prioritisation |
Reachability is the differentiator
“A scanner that ranks findings by raw severity buries your team. The differentiator in 2026 is reachability: does a finding map to code that actually runs and is actually exposed?”
(source: Orca)
This is the appsec version of a problem the vault sees repeatedly — Microsoft’s IR pattern makes the same move when it insists severity be weighted “by deployment domain, affected population, and content nature — not only by record count” (Microsoft IR readiness). Volume without context is noise in both disciplines.
Shift left, then further left
Checkmarx’s five practices for AI-generated code:
- Real-time IDE scanning — catch flaws “as developers write or accept AI-generated code,” before version control
- AI-enhanced SAST for context-aware analysis of “code logic, data flows, and usage patterns”
- Strong AI governance policies — see below
- Augment assistants with dedicated AppSec tooling — because assistants “lack full visibility into the application’s architecture, dependencies, and threat model”
- AI-guided remediation, with the caveat that “suggested fixes must be validated before adoption… without introducing new issues”
CSA pushes earlier still: “Waiting until the pull request or CI pipeline is too late” — instead give the assistant security context at generation time, via an MCP server.
That is the most interesting control in the collection, and it cuts both ways. Feeding security context to a coding agent through MCP is exactly the surface PITAX T42 tool-definition injection targets, where a payload “lands at tools/list time, before any tool is approved or invoked.” A security MCP server is a trusted, privileged tool definition — worth hardening as one.
Governance
Checkmarx’s requirements, which are the practical core of the collection:
- Define which tools are approved, what may be generated, and how outputs must be reviewed
- Restrict access by role, and log usage for audit
- Address data handling so “sensitive code or proprietary logic is not exposed to external AI services”
That last point is a confidentiality concern pointing outward: your source code becomes someone else’s prompt.
Cycode’s prerequisite is inventory: without knowing “which AI tools are being used and what code they produce, there can be no meaningful enforcement of security controls.” Shadow AI defeats governance before it starts — the same argument ATLAS and CoSAI make for asset inventory as the first preparation step.
Secure prompting as a discipline
CSA: “Prompts are now the code design specification. Teach developers not just how to use AI coding assistants, but how to guide them with specificity.”
This follows directly from risks 2 and 3 — ambiguous prompts produce shortcuts and omitted controls. An assistant “will deliver an endpoint that accepts input without validating, sanitizing, or authorizing the payload simply because the prompt never said it needed to.”
Human review still anchors it
CSA: “Human reviewers are still the most important check, but as reviews increase, so does fatigue.”
That is the honest tension. The volume problem is created by the assistants, and the proposed fix — more AI, this time doing review — is the same technology on the other side of the ledger. None of the four sources resolves this; they mitigate it with tooling and accept residual risk.
Vendor caveat
Three of the four sources are vendor marketing (Cycode, Orca, Checkmarx), with product CTAs embedded mid-article. Orca’s guide includes a ranked “best solutions” list featuring itself first. The capability taxonomy is sound and consistent across all three; the tool rankings and the vendor-generated statistics are not neutral. CSA is the only vendor-independent source here, and it is the shortest.
