What is it?
This assessment targets all public-facing systems and services, examining them for known vulnerabilities, misconfigurations, and weak controls. By evaluating external infrastructure from an attacker’s perspective, organisations gain insights into their public security posture and can take proactive measures to reduce exposure.
What could happen?
Unidentified security gaps in external systems can lead to unauthorised access, data theft, or disruption of critical online services. Attackers could exploit unpatched software, weak credentials, or misconfigured firewalls, ultimately harming customer trust, regulatory compliance, and revenue.
What to do about it?
Foundational: Perform routine external vulnerability scans using open-source or low-cost scanning tools to identify basic security gaps.
Outcome: Immediate awareness of common issues such as outdated software versions.
Enhanced: Engage a reputable security provider to conduct periodic external penetration tests. Use the results to guide patching, Comprehensiveening, and service minimisation efforts.
Outcome: Deeper insight into complex vulnerabilities and tailored remediation steps.
Comprehensive: Implement continuous external monitoring and integrate external threat intelligence feeds. Use web application firewalls, advanced DDoS protection, and automated patch management systems to proactively secure the perimeter.
Outcome: A robust, dynamic defence aligned with evolving threats.
