About Notary Project

The Notary Project provides a set of open-source specifications and tools designed to secure software supply chains by enabling cryptographic signing and verification of software artifacts. It supports signing arbitrary blobs, container images, and other software components, ensuring their integrity and authenticity throughout the development and deployment lifecycle. The project is built on standard Public Key Infrastructure (PKI) and supports both online and air-gapped signing scenarios, making it suitable for diverse enterprise environments.

Targeted at DevOps engineers, security operators, and developers, the Notary Project offers fine-grained security policies to enforce trusted identities and registries, enhancing system integrity. Its pluggable architecture and SDK facilitate integration and customization, while multi-registry support ensures portability and immutability of signed artifacts. Adopted by leading organizations such as AWS and Microsoft, the project is community-driven and governed openly under the Cloud Native Computing Foundation (CNCF) incubating status, providing enterprises with a reliable and extensible solution for securing their software delivery pipelines.

How to evaluate Cloud Security & CSPM

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Notary Project. It comes from our Cloud Security Posture Management (CSPM) buyer guide.

25%
Risk Prioritization & Attack-Path Analysis
Context graph that correlates misconfiguration, internet reachability, identity/permissions, vulnerabilities, secrets, and data sensitivity into ranked attack paths to crown-jewel assets; toxic-combination detection; quality of the “fix these 10” output versus raw finding volume; false-positive rate in your own accounts
20%
Coverage Model: Agentless Breadth vs. Runtime Depth
Agentless snapshot/API scanning for fast 100%-estate visibility versus agent/eBPF runtime for in-production threat detection (CDR); container, serverless, and Kubernetes (KSPM) coverage; how the two models combine without double-counting; performance impact and deployment friction
20%
Multi-Cloud & Platform Consolidation (CNAPP)
Depth and parity across AWS, Azure, GCP, OCI, and Kubernetes from one console; how many of CSPM, CIEM, CWPP, DSPM, KSPM, and code/IaC security are genuinely unified on one data model versus bolted-on acquisitions; single policy and one risk score across domains
15%
Identity & Entitlements (CIEM)
Effective-permission analysis across human and machine identities, cross-account and federated role mapping, detection of unused and over-privileged entitlements, least-privilege right-sizing recommendations, and privilege escalation / lateral-movement path discovery
10%
Remediation, Automation & Developer Workflow
Guided and auto-remediation, IaC and pull-request fixes (shift-left to code), guardrails that prevent drift, ticketing/SOAR integration, ownership routing to the right team, and API/Terraform coverage for security-as-code
10%
Compliance, Reporting & SOC Integration
Out-of-the-box frameworks (CIS, PCI DSS, HIPAA, SOC 2, FedRAMP, NIST) with custom policy authoring, audit-ready evidence and drift history, RBAC/SSO on the console, and clean export of correlated cloud risk into the SIEM/SOC rather than a siloed dashboard
