CyberFurl can load analytics only after you opt in. Core product features work without analytics consent.
Perform deep passive and active reconnaissance to identify web servers, MTAs, frameworks, and hidden infrastructure. Analyze HTTP headers, TLS signatures, and SMTP banners to expose potential attack surfaces before adversaries do.
Technology fingerprinting maps the precise versions of software running on your external-facing infrastructure. By correlating HTTP responses, SMTP server banners, and cryptographic handshakes (such as TLS cipher suite preferences), security teams can identify unpatched legacy systems, exposed admin interfaces, and insecure configurations. Threat actors automate fingerprinting to match known CVEs against your attack surface; proactively identifying your technology stack allows you to obscure critical version data and remediate vulnerabilities.
By correlating HTTP responses, SMTP banners, and TLS signatures, security teams can identify unpatched systems before threat actors exploit them.
Leaking Server/X-Powered-By headers, verbose SMTP banners, predictable default error pages, and unique TLS cipher suite ordering.
The scanner initiates connections to common web and email ports to map listening services and identify the protocols in use.
It captures raw HTTP response headers, meta tags, and SMTP 220 greetings to extract explicit version disclosures such as Server, X-AspNet-Version, or MTA identifiers.
By analyzing the TLS ServerHello, the checker evaluates the negotiated cipher suites, ALPN extensions, and elliptic curves to generate a TLS fingerprint, identifying the underlying SSL/TLS library.
The tool sends anomalous requests to trigger specific error conditions, analyzing the structure of the responses to identify backend frameworks that might be obscuring their standard headers.
Deep inspection of HTTP response headers to identify web servers, proxies, WAFs, and application frameworks via Server, X-Powered-By, and proprietary custom headers.
Extract and analyze initial SMTP 220 greetings and EHLO responses to accurately identify the Mail Transfer Agent (e.g., Exchange, Postfix, Sendmail) and its version.
Generate signatures from the TLS handshake to fingerprint the server's cryptographic stack, circumventing application-layer obfuscation techniques.
Identify reverse proxies, Content Delivery Networks, and Web Application Firewalls by analyzing specific HTTP headers, cookie patterns, and response latencies.
Parse client-side HTML, inline scripts, and DOM variables to identify CMS platforms, analytics trackers, and frontend JavaScript libraries.
Receive specific configuration directives to effectively mask your technology stack, such as modifying ServerTokens or disabling X-Powered-By.
Run a comprehensive technology fingerprint scan to uncover exposed software versions and hidden attack surfaces across your web and email infrastructure.
