Exchange Anti Spam Software – The First Line of Defence!
An Exchange anti-spam software’s primary objective is to prevent malicious content from being delivered via email-borne threats. These tools scan email messages, content, and attachments for potential threats and then filter or block suspicious messages from being delivered. Email threats are proven to be one of the main breaches of security to a business and by using an anti-spam tool, you have the ability to prevent employees from being misled through phishing attacks or compromising local networks when downloading malware. Administrators also have the ability to use whitelist approved content or senders while also blacklisting or blocking communications from suspicious parties, as well as preventing employees from delivering information to misidentified users, saving the business from potential breaches which in turn will cost your business money.
All secure email gateway software possesses anti-spam or email filtering capabilities, but those tools also have additional features for comprehensive spam filtering, email encryption, and information archiving.
To qualify for inclusion in the Email Anti-Spam category, a product must be able to filter email content for malware or viruses, have the ability to identify mislabeled senders or potential phishing attempts and provide blacklisting or blocking capabilities to restrict communication with suspicious parties.
Shouldn’t Antivirus be enough to protect my business?
Although you may be led to believe you are safe from just having an Antivirus software installed, this is not the case as this will only prevent malware, spyware and adware from being installed. Not all antivirus programs check incoming emails for malicious programs and URLs, which is why anti-spam software offers an additional level of security. All incoming messages are assessed using an antivirus engine and any email containing a malicious link or infected email attachment will be quarantined to prevent it from being delivered to an end-user. A spam filter should also quarantine phishing emails, which will reduce reliance on employees being able to identify email threats.
Additionally, all spam filters analyze inbound emails, but not all perform checks on outbound mail. Malware could be downloaded from the Internet and inadvertently mailed to another individual within your organization or to a customer, client, or business contact. By checking outbound mail at source, contacts are protected from malicious emails. This feature also helps to prevent an organization being added to a spam blacklist.
