Ensure that your servers/machines are safe and secure by utilising a security scanner to check for vulnerabilities within the services and applications you are running.
Utilising Nessus, you can find out if there are any problems that need to be rectified within the configuration of the services on that particular server/machine, or whether the applications need to be updated. Nessus will scan the server/machine and provide a report at the end with actions that need to be taken based on the vulnerabilities found. This can vary from something as trivial as a configuration change for that particular application, or to update the application to a later version.
Nessus requires a Professional feed for business use that gives access to the full version of plugins available to scan and ensure that your network and machines are secure.
