Advanced Threat Protection (ATP) is a layered security solution within our email filtering that defends against complex malware and cyber-attacks. Emails that pass the initial checks are then analysed in detail by the ATP engine. The variety of attack vectors used today means email protection must be able to identify and cope with a range of methods to defend against potential threats. That is why we use email technology that utilises freezing, URL scanning, rewriting, and sandboxing to keep threats away from your IT infrastructure.

2FA is a security safeguard that requires users to provide two authentication methods to verify themselves. This is important for email security as any potential hacker will not be able to gain control of the mailbox. All email should be protected by 2FA, this can be easily setup and will safeguard your business data.
SPF, DKIM and DMARC are three important email authentication protocols which are designed to help prevent forged emails, they provide assurance that the email received was sent by the sender and has not been spoofed.
Unfortunately, emails can be easily spoofed which means the person sending the email may not be who you think it is as the email address may have been changed, SPF, DKIM and DMARC help prevent this.
These authentication protocols need to be enabled and configured correctly as improper setup will cause unintended mail flow issues, thorough testing is recommended.
Solutions4IT can assist with this process for you and advise what your current email authentication level is.
Email/Spam filtering adds an additional layer to protect your business against potential breaches. Incoming and outgoing emails are scanned for known attack vectors and blocked before they are delivered.
In addition to this the spam filtering considerably reduces the number of unwanted emails that are sent through. Typically, these would be placed into a quarantine which is controlled through allow/deny lists.
A common method used to infiltrate email is to alter where the email was sent from, this can be made to look like the email was sent internally.
An easy approach to safeguard against this is to configure emails to have a label which show if it was sent from an Internal or external sender. Once configured each email will then clearly show if the email was sent from outside your business and helps prevent this common attack vector.
In addition to our 4 step guide to secure emails, your employees should be aware of some straightforward golden rules which they should consider when receiving an email:
Never open an attachment within an email from a company or person you do not know or were not expecting.
Avoid sending any sensitive information over email.
Be wary of opening emails from someone you do not know or trust.
Do not click on links from a company or person you do not know.
Check the senders email address to make sure it is legitimate.
Hover over email links first to show where they are pointing to.
Check for spelling and grammar errors – this is a good indication that the email is not genuine.
When in doubt, call the company that sent the email to verify.
