- Anti spam filtering – minimizes the impact of spam messages for users and IT infrastructure;

- Malware filtering for e-mail traffic – minimizes the exposure to malware threats;

- Ability to detect phishing emails – minimizes the risk of disclosure confidential information;

- Content-aware data loss prevention – minimizes the risk of disclosure confidential information and fulfills compliance regulations;

- Encryption – protects confidential data.

Business Impact

E-mail is one of the top five attack vectors faced by midsize business. Protecting your e-mail systems (and employees who depend on e-mail) should be part of a total security solution that also addresses the other critical vectors you must defend: the web, systems, networks, and data. But whether you address all five areas in a unified approach or concentrate on strengthening your e-mail protection, a Secure Email Gatewayis a mandatory solution to be considered in a security strategy for any organization.

E-mail is an indispensible tool for businesses today, but it’s also a favorite vehicle for spammers and cybercriminals. Not only does spam drain productivity, it can also lure employees to visit inappropriate or malicious websites, putting both the company and the user at risk. Around 90% from the total number of email that hits the gateway is spam. Spam has a great impact on the IT infrastructure because usually contains viruses and other malware, and also because useless inbound traffic.

Unfiltered outbound e-mail can be just as damaging. Unintentional or not, sensitive or regulated information can easily leak out of the organization via e-mail, subjecting the company to substantial regulatory or financial penalties. Your e-mail filter needs to stop all spam and e-mail-based threats, but it must also be able to scan outbound messages and ensure company policy is always enforced.

Since e-mail is considered by many organizations as a business critical tool, measures to mitigate the risks associated with the e-mail traffic have to be taken.

E-mail security technology must support a corporation’s compliance needs regarding email content.

Specific compliance requirements vary from organization to organization, but many industries have to be compliant with major standards as Health Insurance Portability and Accountability Act (HIPAA), the Payment Card Industry Data Security Standard (PCI DSS), the Sarbanes-Oxley Act (SOX), and the Gramm-Leach-Bliley Act (GLBA).

A Secure E-mail Gateway provides protection, cost reduction, increase productivity and helps organizations to be compliant with standard regulations.
