New Insurance Industry Technology Requirements



Is Your Business Meeting New Insurance Industry Technology Requirements?


Insurance Providers Are Changing the Rules

More insurance carriers are now requiring regular IT maintenance; even if you're not experiencing any active issues. This isn't just a recommendation anymore; it's becoming a mandatory condition for maintaining coverage under HITECH, HIPAA, and other technical compliance standards.

The reason? Preventative maintenance significantly reduces the risk of data breaches, system failures, and costly downtime. Insurance providers recognize that businesses with regular IT check-ups file fewer claims and recover faster from incidents.

Windows 10 & 11: Security Policies Block Unauthenticated Guest Access - FIX!


Fixing SMB Guest Access Issues on Windows:

 Registry, Group Policy, and Server-Side


If you're trying to access an SMB share from Windows and getting blocked due to guest access restrictions, you're not alone. Microsoft tightened SMB security in recent versions of Windows, disabling insecure guest logons by default.
