Regulatory & Compliance Risks

• Export controls (EAR/ITAR): dual-use security technology may require export licenses
• FedRAMP: required for federal government contracts
• EU NIS2 Directive: new incident reporting and security requirements for EU customers
• State privacy laws: security products handling personal data face multi-state compliance

OSINT Signals to Check

DDR automatically checks these 4 signals from public sources when analyzing a Cybersecurity startup:

• CVE database: any CVEs attributed to or affecting the product
• Shodan: public-facing infrastructure security posture
• GitHub security advisories for any open-source components
• VirusTotal: check if product binaries trigger any security tool flags
