CloudSploit's hosted product provides many advantages over periodically running a script against your infrastructure.
Primarily, CloudSploit ensures that scans are run at a regular interval, without fail. This guarantees that you never forget to run your script or that new vulnerabilities aren't missed until the next time you remember to run it.
Additionally, CloudSploit provides a historical analysis of every scan it performs, allowing you to track risk status over time and download previous scan reports. This is incredibly useful for compliance and auditing purposes. The scan reports themselves also offer a wealth of information that a command line script does not provide. For example, CloudSploit's reports provide helpful remediation steps, links to AWS documentation, search filters and suppression features.
Finally, CloudSploit can be configured to send alerts to email addresses, SNS topics, or Slack channels whenever risks of pre-defined types are detected. This means you'll never miss a potential compromise or security weakness.
