TLS Inspector test suites for professional certification support

TLS Inspector

Individual certification support for your success

In today's connected world, where sensitive information is transmitted online, data security is a top priority. This is where Transport Layer Security (TLS) comes into play. TLS is a cryptographic protocol that enables secure communication on the Internet. It offers a number of benefits that go far beyond simple encryption and has established itself as a standard for securing IT networks.

However, implementing TLS and using existing libraries correctly is an enormous challenge. The high diversity of configuration options of the production system often leaves dangerous security gaps. Therefore, the software for security-relevant devices must meet the highest security requirements so that they can be operated safely. The German Federal Office for Information Security (BSI) defines these requirements in its Technical Guidelines (TR).

TLS Inspector by achelos

With our powerful TLS Inspector test suites, manufacturers and test centers can now efficiently and flexibly test software for security and compliance for security-relevant devices.

The achelos TLS test suites are already optimised and preconfigured for the requirements according to BSI and Common Criteria. All BSI requirements are fully covered in this way. The test suite is characterised by a high degree of automation and easy integration into other systems.

Verifiable IT security with flexible software tools

Securing your network with achelos test suites

Test your products, solutions and services manufacturer-independently for security and compliance, identify gaps and errors in the implementation and configuration of your network connection and web services and protect them.

Test objectives are to check the complete setup of the TLS connection up to mutual authentication and to react to incorrect behavior, e.g.

  • Missing or incorrect communication parts
  • Incorrect key material
  • Incorrect certificates
  • Unsuitable cipher suites
  • Erroneous reaction to manipulations

The TLS Inspector test suites from achelos can be used flexibly up to automated test runs. A very efficient test management and various simulation environments are available for this purpose. The implementation of the security protocols is examined in detail and results are verifiably logged.

Protocols guarantee authenticity, integrity and confidentiality

The test case catalog is continuously expanded and is based on requirements from the following sources:

  • Functional specifications
  • Technical guidelines (TR) of the BSI
  • Certifications
  • Cryptographic standards
  • Application notes for Common Criteria certification
  • Evaluation standards
  • Penetration tests
  • Common Criteria documentation requirements

Automated testing for professionals

achelos supports

  • Network component manufacturers
  • Evaluators and certification bodies
  • System Operators
  • Company IT departments
  • Government bodies

to protect themselves from cyberattacks.

A large number of test and evaluation houses already use achelos test suites to perform tests as part of accredited testing procedures.

Architecture of the TLS Inspector test environment

The architecture and implementation of the test suites are modular. In this way, different test suites, tools and simulations can be integrated. Automated tests and detailed test reports measure product quality. All you need is a powerful PC, without any special IT infrastructure or complex lab environment.

Your benefits:

  • Easy verification of websites according to BSI guidelines
  • Avoidance of IT configuration errors
  • Compliance with BSI security guidelines
  • Cost savings through faster certification
  • Efficient testing due to high degree of automation
  • Convenient simulation environment and ease of use
  • Test scope, test depth and attack scenarios can be individually selected
  • Reproducible and audit-proof documentation of test results
  • Vendor-independent test environment
  • Development of test suites in cooperation with an accredited test center

Product variants:

The test suites including test tools are available individually:

  • TLS Client Inspector
  • TLS Server Inspector
  • TLS Checklist Inspector


  • Simulation environment
  • Software Development Kit (SDK)

Use the manufacturer-independent test suites from achelos, developed together with an accredited test center, to secure your TLS network connections. Thanks to flexible architecture and implementation, the test suites from achelos can be used immediately, regardless of the products involved.

Fit for certification with achelos!
