★★★ Suggestions & Bug Report at: securityfocus.eu@gmail.com ★★★
ArpGuard protects your Mac by keeping an eye on your Internet network. Even though Mac OS X is already well protected, is vulnerable to a Man in The Middle attack, which can compromise your passwords, bank account information, credit card information and even gain unauthorised access to your Mac.
You may want to check out more Mac applications, such as ESET NOD32 Antivirus Business Edition, SSH Helper or Base64Vue, which might be related to ArpGuard.
