Security check of SSL/TLS protocols and ciphers

To assess the TLS security settings of a web server, you can use SSLCheck from binsec.tools. This free online tool enables users to analyze a server's SSL/TLS configuration in detail. It detects supported protocols (such as TLS 1.1 and TLS 1.3), lists available cipher suites, and provides comprehensive certificate information. SSLCheck supports standard HTTPS ports like 443/tcp, as well as custom ports such as 8443/tcp. In addition to web services, it can also evaluate StartTLS-enabled services like SMTP, IMAP, and LDAP.

Tools

On binsec.tools, you’ll find free online tools for penetration testing – the same ones used by the binsec group in real-world pentests. The publicly available tools are primarily designed to gather information and enrich it with additional data. Check them out!

Manual Penetration Testing by Certified, In-House Senior Penetration Testers

binsec penetration testing

Who tests

For more than ten years, binsec has stood for technically rigorous, strictly manual penetration testing. All engagements are conducted exclusively by employed senior penetration testers. Freelancers or subcontractors are not involved. Our clients work directly with the responsible senior tester who personally performs and technically leads the assessment. Communication is conducted in German and English; international projects are a regular part of our work. Our experts hold recognized offensive security certifications such as OSCP, OSCE, CRTO, and BACPP.

What we test

Our project experience covers complex enterprise networks, modern web and API architectures, and hybrid infrastructures. We work with organizations in manufacturing and industry, financial services and insurance, healthcare, IT and software providers, as well as public institutions. Technical, regulatory, and organizational requirements are systematically taken into account.

How we work

Our tests are based on a structured and reproducible methodology. They align with established standards such as OWASP and OSSTMM and are adapted to the specific project scope. Each assessment follows clearly defined phases: structured reconnaissance, manual analysis, targeted exploitation, and validated impact assessment. Automated tools support the process; identification, verification, and evaluation of vulnerabilities are performed manually.

Where we operate and document

Assessments are not conducted from cloud infrastructures. We operate our own infrastructure in a data center in Frankfurt. From there, all engagements are centrally executed and documented within our internal system PTDoc. PTDoc serves as the central documentation platform for all project data, evidence, and evaluations. All findings are recorded in a structured manner, technically described, risk-assessed, and supported by reproducible proof-of-concept information.

What you receive

We identify technical vulnerabilities and assess their business impact. Findings are evaluated based on risk or CVSS. The result is a clearly structured report including an executive management summary and detailed technical documentation. Re-testing of identified vulnerabilities is an integral part of our service.
