An adversarial verification process can challenge findings before they reach security teams, helping reduce false positives and unnecessary triage work. When a vulnerability requires action, Safeguard can create a compatible patch, open a pull request, run the organization's CI and tests, and merge the fix according to configured policies. The platform generates and maintains SBOMs, tracks SLSA provenance, monitors containers and dependencies, and records evidence for regulatory and compliance requirements. Its Eagle model is designed to discover previously unknown vulnerabilities and coordinate mitigations before public CVEs or upstream patches become available. Safeguard also provides runtime guardrails for LLM applications, a zero-CVE component registry, public Trust Centers, vendor risk capabilities, and security-focused coding tools. A tenant-scoped MCP server allows platforms such as Claude, Cursor, and custom AI agents to query vulnerabilities, run scans, create remediation plans, and trigger approved security actions. Organizations can deploy Safeguard in cloud, private, on-premises, or fully air-gapped environments while using one centralized policy and audit system across software security and compliance workflows.
