+# SecureSBOM vs Sigstore
+
+A detailed comparison of **SecureSBOM** and **Sigstore**, two solutions addressing software supply chain integrity through signing and verification technologies.  
+While **Sigstore** focuses primarily on open-source ecosystems and OCI artifacts, **SecureSBOM** is built for enterprise-grade SBOM signing, verification, and compliance.
+
+---
+
+## 🧩 Primary Use Case
+
+| Tool | Description |
+|------|--------------|
+| **Sigstore** | Open Source Software, OCI-Focused (SBOMs attached as a container artifact). |
+| **SecureSBOM** | Business / Enterprise Software, purpose-built for SBOM signing and verification. |
+
+---
+
+## 📘 SBOM Support
+
+| Tool | Description |
+|------|--------------|
+| **Sigstore** | Treats all SBOMs as simple blobs. Supports **detached signatures only** for both SPDX and CycloneDX. |
+| **SecureSBOM** | Integrates directly with the **CycloneDX SBOM format** — supports **embedded signatures**, **property exclusion**, and also supports **SPDX detached signatures**. |
+
+---
+
+## 🔐 Key Management
+
+| Tool | Description |
+|------|--------------|
+| **Sigstore** | Ephemeral, short-lived keys/certificates from **Fulcio** with **OIDC authentication** — or manual key management (local or via cloud providers like GCP/AWS). |
+| **SecureSBOM** | **Automated** key lifecycle management using **cloud HSMs**. Ideal for enterprise compliance and long-term trust. |
+
+---
+
+## 🪪 Authentication
+
+| Tool | Description |
+|------|--------------|
+| **Sigstore** | OIDC (for keyless signing) or manual authentication for self-managed keys. |
+| **SecureSBOM** | Authenticated via **API Key**, enabling fine-grained access control and multi-tenant isolation. |
+
+---
+
+## 🔍 Transparency
+
+| Tool | Description |
+|------|--------------|
+| **Sigstore** | Public Record via **Rekor** (Certificate Transparency Logs). Verification relies on transparency records and public keys. |
+| **SecureSBOM** | **Private Record** system — verification performed using the **associated public key**, keeping enterprise signing activity confidential. |
+
+---
+
+## 🧠 Summary
+
+- **Sigstore** simplifies signing for open-source contributors and CI/CD pipelines relying on OIDC identity proof and public transparency.  
+- **SecureSBOM** focuses on enterprise adoption, providing stronger SBOM format integration, private key isolation, HSM-backed signing, and internal verification capabilities.  
+
+---
+
+### ✅ Ideal Fit
+
+| Use Case | Recommended Solution |
+|-----------|----------------------|
+| Open Source Ecosystems | **Sigstore** |
+| Enterprise Software & Supply Chain Security | **SecureSBOM** |
