The client has the option to blacklist or whitelist any email address or domain based on the sender and recipient filters. If they want, they can restrict any IP addresses so email won't be received from those IP addresses.
Barracuda Email Security Gateway effectively blocks nearly 99% of threats and offers Advanced Threat Protection against zero-day attacks, ensuring strong email security. However, issues like false positives, non-customizable aggressive spam filtering, and insufficient anti-phishing features are noted. Users also report integration challenges, limited updates automation, and inadequate multi-domain management support, though the quarantine service enhances IT communication. Tech buyers may find its security features valuable but should consider potential operational limitations.
