Poseidon Navigation’s solution to cyber security on the bridge – ChallengerShield provides a secure method for transferring files between e-mail and internet enabled PCs and the ECDIS, or other important equipment on the bridge, by locking down the ChallengerShield USB stick with a with low level file system, leaving no empty storage space meaning harmful files cannot be intentionally or unintentionally transferred.

Only a protected USB can then be used on the bridge, which provides the user with options for common operations such as copying ENC permits or updates. Files also cannot be added to the USB stick outside of the ChallengerShield software environment, to maintain its security.
