Email Security

Email security solutions protect organizations from unwanted threats and attacks against incoming and outgoing emails and attachments.

Why hosted email security?
Today, email security is a fact of life. Because we love email and can’t do business without it, hackers have developed a deep passion for launching malicious attacks intended to disrupt our daily business activities and wreak havoc on our networks. To fight back, a variety of email security solutions are now available to thwart these types of attacks.

While email security was once only available via on-premise software or an appliance, the industry has evolved and several good email security solutions are now delivered through the software-as-a-service (SaaS) model. Opting for the SaaS delivery model offers a variety of benefits. Organizations don’t have to install any hardware or software to run the service, and the update and maintenance processes are automatic and included in a flat per user, per month fee.

Companies moving their email to the cloud often find that the email provider offers a built-in email security solution. However, some hosted providers let you select your own security solutions, so it’s smart to understand your options (see table below).

In addition, we have gathered a variety of helpful resources to keep you informed of industry happenings and events.

Whichever solution you select, make sure it includes at least some or all of the functionality mentioned below:

• Spam filtering: A set of security measures that help to reduce the amount of spam that enters email inboxes.
• Advanced spam blocking: “Intelligent” filtering features that use Bayesian analysis and other system algorithms to block spam messages.
• Virus and worm scanning: Blocks viruses and worms (self-replicating programs) from harming your network.
• Content and attachment filtering: Scans the content of emails and their attachments to ensure they are free of dangerous content.
• Phishing/fraud protection: Thwarts attempts by hackers to secure sensitive information such as passwords and credit card details from recipients.
• Email/Denial-of-service (DoS) attack protection: Minimizes the risk of catastrophic attacks that can render entire networks unavailable.
• Outbound message filtering: Ensures the safety of messages as they leave your network and prevents harmful messages from being sent via your network.
• Quarantining: Provides a temporary storage location for messages that are identified as spam and that should not be delivered to a user mailbox inside the organization. This feature also stores “false positive” messages so that users can retrieve and whitelist them, if necessary.
• Real-time monitoring: Ensures that your network is protected around-the-clock since attacks can occur at any time.
• Reporting: Provides the administrator with reports of the spam filtering and activity taking place.
• Policy-based encryption: Automatically encrypts sensitive information prior to transmission so that it cannot be read if intercepted.
