Product compatibility is usually asked from the product vendor, not from the OS vendor, generaly.
It's look like this product is not compatible with Solaris.
But You can scan Solaris system by this product for check on known vulnerabilities
Thank you for your reply. Would you know if there's an existing Security Agent that is compatible or worked before with Solaris?
Nessus works fine with Solaris 11. We run scans every weekend on our Solaris estate.
