Apple is trying to improve the security of its devices and stop the proliferation of dubious applications and PUPs (Potentially Unwanted Programs) within its ecosystem continuously. One such security service is tasked with scanning the installed applications and flagging those with suspicious or unverified digital signatures and certificates. For the most part, the security feature is doing its job of highlighting intruder applications that might have slipped onto the device without the user realizing it. This will result in a warning prompt stating that '[App] will damage your computer.'
However, under certain circumstances, legitimate applications or device drivers may be flagged and trigger such a response from the macOS. This is exactly the case with users encountering the 'Ciscod will damage your computer' error. This is not the first process associated with the legitimate Cisco AnyConnect software suite to get flagged by Apple's security measures.
'Ciscod' is an executable from the AnyConnect endpoint agent that is responsible for carrying out auxiliary functions and it got targeted due to a certificate issue. To fix the error and stop the intrusive warning prompt from disrupting your activities on the device, you may need to download the latest version of the Cisco software. Just to be on the safe side, you also might want to run a malware scan of the device with a trusted security solution.
