Flaw.co offers a free external security scan that comprehensively evaluates your domain's perimeter for potential vulnerabilities. Key features include: • Passive scan for exposed MCP/Model Context Protocol and agent endpoints • Evaluation of TLS configurations and HTTP headers • Detection of exposed services and information disclosure • Instantly generates a letter-grade PCI readiness signal This service identifies risks from an external perspective, mirroring how an attacker would approach your system, using only your domain name. It focuses on identifying MCP servers and agent endpoints that, if left without authentication, could provide unauthorized access to tools like file systems, databases, or internal APIs. This includes a review of crucial security elements such as `Strict-Transport-Security` headers for TLS, which are vital for preventing downgrade attacks. The scan provides a detailed report that outlines detected issues, explains their significance, and offers clear remediation steps. Every finding is mapped directly to a specific PCI DSS requirement, making it easier to understand compliance gaps. It also highlights broader security posture issues, such as the absence of multiple baseline security headers, which can signal a lack of active security maintenance. Designed for organizations prioritizing external security posture and PCI compliance. Get an immediate assessment of your domain's exposed surface without needing an account for the initial scan. This foundational scan provides actionable insights to bolster your digital defenses.
