Vulnerability Scanner
Passive vulnerability assessment for web applications and infrastructure.
Automated Attack Surface Analysis
ReconShield's Vulnerability Scanner acts as an automated reconnaissance engine. It maps your external attack surface by aggregating data across DNS, SSL/TLS configurations, open ports, HTTP headers, and exposed technologies. By correlating this data against known threat patterns and common misconfigurations, the engine identifies potential entry points before attackers can exploit them.
How It Works: Passive Reconnaissance
Unlike aggressive penetration testing tools that brute-force directories or inject SQL payloads, our scanner operates strictly passively. It acts like a standard web browser and DNS client, gathering information through normal operational queries. We analyze server banners, error messages, routing paths, and public intelligence feeds to build a comprehensive risk profile with zero impact on your server's availability or performance.
Why Continuous Assessment Matters
Security is not a point-in-time state. A configuration change deployed by a junior developer can inadvertently expose a database port to the internet. A marketing team might point a subdomain to a SaaS tool and later cancel the subscription, leaving a Subdomain Takeover vulnerability. Continuous vulnerability scanning ensures you maintain visibility over infrastructure drift and shadow IT.
Frequently Asked Questions
What is passive vulnerability scanning?
Passive scanning identifies vulnerabilities by analyzing server responses, headers, and public records without sending intrusive or malicious payloads to the target.
Is vulnerability scanning legal?
Passive scanning (which ReconShield uses) is generally legal as it only observes public configurations. Active scanning requires explicit authorization from the asset owner.
How often should I scan my website?
Continuous scanning is recommended. The attack surface changes daily as new vulnerabilities (CVEs) are discovered, certificates expire, and infrastructure is modified.
