Cyber Hygiene Services

Reduce the Risk of a Successful Cyber Attack

Cyber threats are not just possibilities but harsh realities, making proactive and comprehensive cybersecurity imperative for all critical infrastructure. Adversaries use known vulnerabilities and weaknesses to compromise the security of critical infrastructure and other organizations. CISA offers free cybersecurity services to help organizations reduce their exposure to threats by taking a proactive approach to monitoring and mitigating attack vectors.

By taking advantage of CISA’s Cyber Hygiene services you can:

• Significantly Reduce Risk.
  
  • Organizations typically reduce their risk and exposure by 40% within the first 12 months. Most see improvements in the first 90 days.
• Avoid Surprises.
  
  • Because the services look for assets exposed to the internet, they identify vulnerabilities that could otherwise go unmanaged.
• Sharpen Your Response.
  
  • By combining the vulnerability insights gained with existing threat detection and risk management efforts, enrolled organizations can increase the accuracy and effectiveness of response activities. This means fewer false alarms and less chance of real dangers slipping through the net.
• Broaden Your Security Horizon.
  
  • CISA’s scanning is about more than pinpointing vulnerabilities; it’s about expanding your organization’s security boundaries. From basic asset awareness to daily alerts on urgent findings, you’ll be in a better place to make risk-informed decisions.

 CISA's Cyber Hygiene services include:    

• Vulnerability Scanning: This service continuously monitors and assesses internet-accessible network assets (public, static IPv4 addresses) to evaluate their host and vulnerability status. In addition to weekly reports of all findings, you’ll receive ad-hoc alerts about urgent findings, like potentially risky services and known exploited vulnerabilities.
• Web Application Scanning: This service deep-dives into publicly accessible web applications to uncover vulnerabilities and misconfigurations that attackers could exploit. This comprehensive evaluation includes, but is not limited to, the vulnerabilities listed in the OWASP Top Ten, which represent the most critical web application security risks. This service provides detailed reports monthly, as well as on-demand reports to help keep your web applications secure.  
• Video: Strengthening Cyber Defenses: CISA’s Free Vulnerability Scanning Explained: In this video, CISA highlights the benefits of enrolling in free its Vulnerability Scanning service to improve critical infrastructure cyber defenses. Learn how this service can help organizations identify vulnerabilities, sharpen their response, and significantly reduce risk—all while strengthening their defenses against evolving cyber threats.

Additionally, CISA recommends you further protect your organization by identifying assets that are searchable via online tools and taking steps to reduce that exposure.
