Sign up for CISA's Cyber Hygiene Vulnerability Scanning. Register for this service by emailing firstname.lastname@example.org. Once initiated, this service is mostly automated and requires little direct interaction. CISA performs the vulnerability scans and delivers a weekly report. After CISA receives the required paperwork, scanning will start within 72 hours and organizations will begin receiving reports within two weeks. Note: vulnerability scanning helps secure internet-facing systems from weak configurations and known vulnerabilities and encourages the adoption of best practices.
