Frequently Asked Questions
What is Attestari?
Attestari provides an independent examination of the packages that AI agents install. It reads the exact file downloaded by a package manager—not the source repository—and runs a fixed set of checks on every MCP server and agent tool listed in public registries. For each finding, Attestari publishes the file name, line number, and exact text that triggered the issue, and if a package cannot be read, it reports the reason instead of assigning a grade. All verdicts are public and no publisher pays for the assessment. Grading is based on the highest confirmed severity of findings: Grade A for no confirmed findings, Grade B when the highest confirmed severity is low, and an F for any high‑severity finding. Packages that cannot be fully examined receive no grade, with the limitation recorded. The methodology emphasizes transparency, artifact‑level analysis, and continuous re‑examination of each version rather than a one‑time registry check. GateOnAI Score: 67/100.
What is Tenable Pro AI?
Tenable One is an AI‑powered exposure management platform that unifies security visibility, insight, and action across an organization’s entire attack surface. It aggregates native signals, exposure intelligence, and third‑party data to map infrastructure, cloud, identity, OT, third‑party applications, and AI components, giving security teams a complete view of exposures. The platform continuously enriches exposure data to connect potential risk with exploitation pathways, enabling risk‑based prioritization and highly orchestrated remediation. Tenable Hexa AI agentic orchestration accelerates remediation, shortening detection‑to‑resolution time so exposures are eliminated before they become breaches. Tenable One also provides cross‑domain exposure management, revealing how weaknesses in one area can affect others, and offers specific visibility into AI supply chains, cloud misconfigurations, OT environments, and identity infrastructures. Vulnerability management features continuously discover assets and prioritize the most exploitable flaws, helping teams focus on the highest‑risk issues. GateOnAI Score: 62/100.
