With the availability of easily accessible attack tools, everyone is at risk - including school districts. New vulnerabilities and exploits are discovered on a daily basis.

Mid-sized and small K-12 districts used to feel a certain amount of safety in security through obscurity - meaning a feeling that you don’t have anything hackers want - they’ll leave you alone.
