Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Sonicwall FIPS mode:
When operating in FIPS (Federal Information Processing Standard) Mode, the SonicWALL supports FIPS-Compliant security. Among the FIPS-compliant features of the SonicWALL include PRNG based on SHA-1 and only FIPS-approved algorithms are supported (DES, 3DES, and AES with SHA-1).
Select Enable FIPS Mode to enable the SonicWALL to comply with FIPS. When you check this setting, a dialog box is displayed with the following message: Warning! Modifying the FIPS mode will disconnect all users and restart the device. Click OK to proceed. Click OK. The SonicWALL reboots in FIPS Mode.
To return to normal operation, uncheck the Enable FIPS Mode check box. The SonicWALL reboots into non-FIPS mode
