Partner with CastileThe work, in practice / Healthcare
A healthcare credentialing company needed to bring its email, policies, and safeguards into line with the information it was trusted to protect.
Over a year of managed security, we moved the business to managed email, enforced multi-factor authentication and encryption, trained the team, and built its HIPAA policy set.
