What is a Quarantine Digest?

Forget the ‘Hollywood hacker’. Cybercrime rarely involves a criminal frantically typing reams of code into a glowing green screen.

It’s a bit more mundane than that. They send you an email.

A staggering 91% of cyber attacks begin with an email message. It’s the starting point for everything from ransomware to phishing scams. It makes sense, then, for cyber-security businesses to focus a significant part of their strategy on keeping harmful emails away from users.

That’s where an email quarantine digest comes in.

Quarantine Digest — A Lockdown for Suspicious Emails

There are various options to deal with emails in quarantine 

An email quarantine digest is a summary of messages that have been quarantined by an email server or service. This might be because they have been flagged as potential spam, as containing malicious content or because they breach your organisation’s policies (for instance, they exceed a size limit). Quarantined messages are typically held in a separate area, or ‘quarantine,’ until they can be reviewed and either released or deleted. Think of it as a lockdown for potentially harmful emails. 

The quarantine digest is typically sent to the email account owner on a regular basis, such as daily or weekly. It lists the quarantined messages along with information about why they were quarantined.

How Do I Get an Email Out of Quarantine?

An email quarantine digest will allow you to release individual messages from quarantine or to report them as false positives.

On top of this, your quarantine digest should use rules to help you fine-tune the quarantine software’s approach, to ensure you are getting the emails you need and rejecting the unwanted or harmful emails. These rules may include:

  • Deliver
  • Always Allow Sender Address
  • Always Allow Sender Domain
  • Delete
  • Always Block Sender Address
  • Always Block Sender Domain

Why is it Important that My Organisation Uses a Quarantine Digest?

By quarantining potentially harmful messages, an email quarantine digest helps protect your inbox from spam, phishing attempts, and other types of malicious content. This can help reduce the risk of falling victim to scams or having your personal information compromised.

An email quarantine digest can help to keep your inbox organised by removing unwanted messages. It’s going to help with your focus and quality of life, too. Nobody wants to be reacting like Pavlov’s dog to the ping of SPAM or marketing guff. Your quarantine digest can go a long way towards keeping these mails out of sight and out of mind.
