What are Vulnerability Scanners?
Vulnerability scanners are security tools that automatically identify known vulnerabilities, misconfigurations, outdated software, exposed services, and security weaknesses across IT environments. These tools scan networks, applications, cloud resources, endpoints, containers, databases, and other assets to detect potential security risks before they can be exploited by attackers. Vulnerability scanners often provide risk prioritization, severity ratings, remediation recommendations, compliance checks, and continuous monitoring to help security teams manage exposures efficiently. Many solutions integrate with vulnerability management platforms, SIEM systems, ticketing tools, and security operations workflows to streamline remediation efforts. By continuously assessing security posture and identifying weaknesses, vulnerability scanners help organizations reduce cyber risk, improve compliance, and strengthen overall security defenses.

Astelia
Astelia
Astelia is an attack-driven exposure management platform designed to help security and IT teams identify which vulnerabilities in their environment are truly reachable and exploitable. It maps network topology through read-only integrations and applies agentic AI to analyze the technical requirements of each vulnerability, correlating reachability and exploitability data to surface the small fraction of risks that actually matter. Instead of relying on probability-based scoring alone, Astelia provides evidence-based prioritization that helps organizations cut through massive vulnerability backlogs and focus remediation efforts where they will have the greatest impact. It also visualizes potential attack paths using graph-based models, showing exactly how an attacker could move through the network to compromise assets. In addition, it exposes coverage gaps by mapping infrastructure down to the port level, revealing unscanned assets and third-party connections. -
