CompuLert™ NEXGen Represents World-class Security

CompuLert™ NEXGen provides security at varying layers to protect against external threats. Sensitive data for the application is secured to protect against inappropriate user input as well. All access to administration features is password protected and requires authentication. The passwords have been encrypted to further protect from malicious access.

All network connections use a secure SSL connection to prevent snooping or “Man-In-The-Middle” attacks. CompuLert™ NEXGen is also capable of working with entirely isolated network resources, with no dependence on cloud resources or internet access, aside from the optional NOAA feed.

CompuLert™ NEXGen protocol messages exchanged between the server and clients are encrypted at application level. The application uses the symmetric Advanced Encryption Standard (AES) for encrypting messages
