Email remains a, if not the, key threat vector for protecting organisations from cyber crime – with around 90% of cyber attacks beginning by compromising an unsuspecting user via email.
Today we take a closer look at some of the clever tricks of Barracuda’s email filtering & security service, and why the small investment to protect your inbox is worth it:
Attachment Scanning
In addition to profiling every email which passes through its live email filtering service in seconds, Barracuda scans each email attachment for signs that the contents might be malicious.
As cyber criminals begin to use more sophisticated means, it’s worth implementing this to prevent macro-enabled office documents, infected PDFs and similar file download tricks from catching out users who might be curious to open a dangerous attachment.
Outbound
Barracuda email filtering scans not just incoming, but outgoing emails from your hosted mail service or mail server, ensuring not only that your clients are protected from suspect emails, but that staff cannot circulate threats further within your organisation.
Anybody familiar with being caught in a reply-all ’email storm’ knows how quickly bad email can spread internally – be part of the solution yourself, not the problem.
Email Spooling
In the event that your email service falters, clients quickly begin receiving bounce-backs, which leave a poor impression of customer service.
This is avoidable – routing via Barracuda’s email servers, emails will temporarily ‘spool’ like planes stacking over an airport, ensuring onward delivery later when the service comes back online. This ensures any unfortunate interruption to communications is not immediately visible to your clients.
Long Term Recovery
Hosting your email in the cloud with Microsoft Office 365? Everything is backed up in the cloud, correct? Not quite – even Office 365 has a 30-day recovery period on deleted email, and emails can ultimately only be restored individually.
This retention period can be longer, or even unlimited, with Barracuda email backups, making sure that emails can be recovered long after staff have deleted them, accidentally or otherwise.
This extra silo of automated email backup protects not just against employee negligence or malpractice, but also common digital breaches such as compromised accounts.
