A free directory of the registries, agencies, and standards bodies that anchor cybersecurity — CISA, NIST and the NVD, MITRE and the CVE Program, FIRST, CERT/CC, OWASP, ISO, ENISA, the NSA, and the FBI's IC3. Each entry lists the body's role, jurisdiction, and official URL. Platform-curated public-domain reference data, free for security engineers, GRC teams, and incident responders.

A free glossary of cybersecurity terms and codes — CVE, CVSS, CWE, CPE, KEV, zero-day, MITRE ATT&CK, indicators of compromise, ransomware, phishing, MFA, SIEM, and Zero Trust — with precise plain-language definitions grounded in NIST, MITRE, and FIRST references. Platform-curated public-domain reference data, free for security teams, auditors, and technical writers.

A free, platform-curated benchmark set for cybersecurity — cumulative and yearly CVE publication counts, the CVSS v3.1 severity bands, the size of the CISA Known Exploited Vulnerabilities catalog, and widely cited data-breach cost and time-to-contain figures — drawn from the National Vulnerability Database, FIRST, CISA, and established industry reports. Period-tagged and sourced. Built for security teams, risk analysts, and CISOs.

Official reference for the Cybersecurity vertical. Buyers are security agents triaging patch queues, insurers underwriting cyber risk, and threat-intel platforms. Public CVE feeds are free, so paid value concentrates in three places: exploitation observability (is this CVE actually being exploited, where, at what volume), exposure measurement (how many reachable instances of the vulnerable service exist, trending), and consequence data (breach cost and downtime distributions by sector). Structure rows as the examples show, and timestamp everything — this vertical decays by the hour. Strict rules: no stolen data, no credential dumps, no personal data from breaches — exploitation telemetry and exposure counts only, lawfully collected. Honeypot and sensor-network operators have natural listings here; state your sensor coverage so buyers can weight your observations. The limited listing type suits fresh exploitation intel. Listing is free, sellers keep 95% on everyday sales from $20 to $49,999.99 under the year-one founding rate locked through 2027-06-30 (full schedule: GET /api/meta), and zero-storage delivery relays from your endpoint at each sale. This reference is free — use it to test the buy flow.
