    When the infrastructure landscape and risk profile is not well known and is legacy, Intruder can scan and automate reporting on open security risks, as well as coordinate responses.

    Open Source
    It is best suited in those environments where complexity is not the key. We've used it fairly extensively in our UNIX to find weak UNIX passwords and in Windows environments too. It's very easy to get hold of as it is essentially Open Source, although a paid version is now available and we are thinking of looking at this proposition in-depth to see if it is viable. We found it easy to install and deploy across our systems. Patching was fairly regular, so we always had the latest version. It holds its own against DES and Blowfish encryption algorithms among many others.

    • It needs to be modified to be able to break SHA 256, 512 and the lastest hashes.
    • Can be slow and wildly against the lastest hashes.
    • Require admin access to set up account.
    • Old and is being superseded by better applications.

    Intruder focuses on scanning network blocks for your servers even if you don't know which services or hostnames are running on them, unlike Detectify which requires a domain or hostname to scan. The network port scanning of Intruder is also broader than many competitors.

    'John the Ripper' being open source was free to use, whereas the others had to be paid for. It was very simple to install and runs against many hundreds of hashes and crypts. It is always developing thanks to large communities on GitHub.
