Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.\nMore information on recommended practices can be found in the reference section (Defense in Depth for B&R products )", "title": "General security recommendations" }, { "category": "other", "text": "For additional instructions and support please contact your local B&R service organization.
