GitGuardian Platform vs Tenable.io Web Application Scanning comparison

GitGuardian is the credential layer security platform for securing the secrets that let code, machines, and AI agents access systems and act as trusted identities. API keys, tokens, passwords, and other secrets carry real access. When they leak, attackers do not need to break in, they can log in. The scale of the problem keeps growing: 28.6 million new secrets were exposed on public GitHub in 2025, a 34% year-over-year increase and the largest jump on record.

GitGuardian finds the secrets that matter across an organization's entire secrets surface, inside and outside the perimeter. Internal Secrets Monitoring detects hardcoded credentials across private repositories, CI/CD pipelines, container images, cloud configs, and collaboration tools like Slack, Jira, Confluence, and Google Drive, using 550+ detectors with live validity checks that confirm each secret is active before it hits your queue. Public Secrets Monitoring scans public GitHub (1B+ commits per year) and DockerHub in real time for corporate secrets exposed online. Developer Endpoint Protection extends coverage to the developer machine itself: config files, shell history, MCP configs, and files persisted by AI coding agents like Claude Code, Cursor, and Copilot. AI Hooks add runtime guardrails inside the agents, checking prompts before they are sent.

For every secret it finds, GitGuardian reveals context and blast radius. NHI Governance supplies that identity layer, discovering every machine identity across repos, CI/CD, cloud, and collaboration tools, attributing ownership, scoring risk, helping configure rotation policies, and surfacing continuous compliance evidence for PCI-DSS v4.0, NYDFS, DORA, NIS 2, and NIST 800-53.

The detection surfaces find what's leaking. The identity layer connects each leak back to who owns it and what it accesses. One closed loop, from a developer's laptop to public GitHub. Honeytokens alert teams the moment an attacker uses a decoy credential.
