As with our hardware, we conduct pen tests and attack surface analyses in order to continuously improve our software. Wherever possible, encryption and signature algorithms are used that comply with the current state of the art (see Properties of the installation package). Exceptions to this are older protocols that do not support encryption (e.g., SNMP v1, ModBus or S7-300 communication).

For the sake of integrity all installation packages are digitally signed to ensure that any tampering with the installation package can be easily detected (see Original (left) and modified package (right)).
