Securie vs Prompt Security
Prompt Security is an enterprise GenAI runtime guardrail platform — primarily protects deployed AI apps and employee AI usage. Securie covers PR-time + deploy-time + runtime + supply-chain + attestation, on AI-built SaaS specifically. Different scopes; here's the honest read.
People searching 'Securie vs Prompt Security' in 2026 split into two audiences. The first is AI-built SaaS founders evaluating which AI-security vendor fits their stack — usually they discover Prompt Security is enterprise GenAI runtime-first while Securie covers the code-side too. The second is enterprise security teams comparing GenAI vendors (Prompt Security / Lakera Guard / Microsoft AI Defender) and adding Securie to the matrix because of its breadth (PR-time + supply chain + attestation). Both audiences typically end up with both — Prompt Security as runtime guardrail, Securie as prevent-and-attest — rather than choosing one.
Prompt Security wins on enterprise GenAI runtime guardrails (Lakera-adjacent). Securie wins on the full AI-built-app lifecycle: PR-time auto-fix + deploy-time gate + runtime eBPF + supply-chain SBOM/AIBOM + auditor attestation. Often complementary rather than substitute.
Feature comparison
| Securie | Prompt Security | |
|---|---|---|
| Primary surface | PR-time + deploy-time + runtime + supply-chain + attestation | Runtime LLM guardrails (input/output classification + policy) |
| Code-side coverage | GitHub App with 22 specialists (RLS, BOLA, leaked keys, etc.) | Limited — Prompt Security is runtime-first |
| Sandbox verification | Firecracker-microVM exploit reproduction per finding | Classifier confidence; no exploit reproduction |
| Auto-fix PR | Framework-aware merge-ready PR comment | Runtime block + alert; no code-side patch |
| Attestation chain | DSSE + SLSA Level 3 + optional Sigstore rekor | None |
| AIBOM / Article 11 | CycloneDX 1.6 AIBOM auto-generated per release | Out of scope |
| Pricing | $0-$299/mo across 4 tiers | Enterprise contracting |
Where the difference shows up in practice
Customer-support chatbot ships with no input sanitization
Prompt Security: Catches at runtime via LLM01 classifier.
Securie: Catches at PR-time via the prompt-injection specialist + auto-emits the SafetyFilter wiring.
Lovable-generated app exposes Supabase service-role key
Prompt Security: Out of scope.
Securie: Secret_scanner live-validates + opens rotation playbook + RLS audit.
MCP server ships rug-pulled tool catalog
Prompt Security: Limited coverage.
Securie: MCP guard's TrustedCatalog refuses drift + ScopeGuard fail-closes the dispatch.
The deeper tradeoff
Prompt Security is one of the strongest enterprise GenAI runtime guardrails on the market in 2026. Its scope is the live LLM call — classify inputs, classify outputs, enforce policy, log to SIEM. That scope is genuinely valuable for enterprises with thousands of employee AI users and hundreds of internal AI apps. Securie's scope is different: the AI-built-app lifecycle, end to end. Securie catches the bug at PR-time before it ships (BOLA, leaked secrets, missing RLS, prompt-injection-in-LLM-features), gates the deploy if a regression slips, runs eBPF on customer-app containers post-deploy, emits SBOM/AIBOM/attestation chain on every release, and produces an auditor bundle on demand. The two products complement; they rarely substitute.

Migration playbook
Step 1: Keep Prompt Security if needed
What: Runtime guardrails for enterprise GenAI deployment.
Why: Prompt Security is genuinely strong on this surface.
Gotchas: Don't expect it to cover code-side or supply chain.
Step 2: Install Securie GitHub App
What: Code-side + deploy-side + supply-chain coverage.
Why: Catch the bugs that Prompt Security's runtime view can't see at PR-time.
Gotchas: Free tier covers 1 repo / 20 scans/mo — upgrade to Indie ($12) for 3 repos.
When to pick Prompt Security
Your primary security need is runtime LLM guardrails for an enterprise GenAI deployment with hundreds of internal users, and PR-time + deploy-time + supply chain are covered elsewhere.
When to pick Securie
You ship AI-built SaaS, you want PR-time auto-fix + deploy-time gates + supply-chain attestation + runtime coverage in one product, on the AI-built-app slice specifically.
Bottom line
Pick Prompt Security if your primary need is runtime LLM guardrails for an enterprise GenAI deployment with hundreds of internal users. Pick Securie if you want full-lifecycle coverage on the AI-built-app code + runtime + supply chain + auditor surface.
FAQ
Can I run both?
Yes. Prompt Security as the runtime guardrail at scale; Securie as the prevent-and-attest layer on the code + supply chain.
Does Securie do runtime?
Yes — runtime eBPF for customer-app containers ships alongside MVP. The runtime scope is the customer's app, not employee AI usage.
What about employee AI usage?
Out of Securie's launch scope (per CLAUDE.md). Securie protects what the customer builds + ships; employee AI usage is shadow-AI / browser-side governance, served by Prompt Security or Lakera.
Is Securie an OWASP LLM Top 10 scanner?
Yes — the 22-specialist roster maps category-by-category to LLM01..LLM10. See /guides/owasp-llm-top-10 for the mapping.
