Businesses rely on productivity, teamwork
and fast communication for success. Teams need to be able to work together on
documents, instantly get feedback from colleagues, and have access to all their
shared files, on all their devices.
This has been made possible by a
revolution in corporate communications with the release of Office 365 and
G-Suite. These cloud platforms offer a monthly subscription of apps including email,
document sharing, and cloud storage to name a few, bundled into one neat
package that works everywhere, anytime.
It’s a business’s dream come true,
right? An opportunity to kick out the dusty on-premise appliance, ditch the
MSP, and move to the bright future of the cloud, where email security is an
issue of the past and nothing ever goes wrong?
Well, not quite.
Many small and midsized organizations
around the world are finding that despite moving their employees on to Office
365 and using Exchange Online Protection, they’re still getting hundreds of
spam emails, phishing attacks and malware delivered to their users’ inboxes.
This article will explore why these
problems persist and how you can secure your business, employees and networks,
while maintaining the benefits of Office 365.
Why Office 365 Isn’t Secure
Office 365’s inbuilt security does not adequately blocks spam, malware, ransomware, or any other email threats. A recent report from Avanan found that 25% of phishing emails bypassed Office 365’s internal filters.
This is a huge problem from a
security perspective. Email is the number one attack vector used to target
businesses. Attackers realize that email is one of the weak spots in business
infrastructure that can be exploited to breach data and gain access to
Small and medium sized businesses
are particularly at risk, because attackers know they don’t expect attacks,
spend far less on security and are unlikely to have strong email security in
Office 365 is used by over 135
million commercial users, so attackers see it as a prime target. This means
it’s absolutely crucial that businesses using Office 365 for email have robust
security technologies in place.
If nothing else, it means you can
get back to creating, innovating and making sales, without having to stress
about hackers or phishing attacks.

Start a Trial of IRONSCALES ->
Ironscales operates within Office 365 and is deployed in less than 5-minutes. As it is operating within Office 365, it is able to scan Internet AND internal email.
In testing by Expert Insights, we discovered that Ironscales successfully detected numerous phishing and malware threats that were missed by Microsoft Advanced Threat Protection.
Ironscales provides organizations with the following protection;
- Attachment sandboxing – Email attachments are sandboxed and scanned using 2 AV engines, including Checkpoint Sandblast.
- URL scanning – URL’s embedded in emails are checked against over 30 different URL databases. This is highly effective at detecting malious URLs
- Phishing Protection – Ironscales is highly effective at detecting phishing emails. In testing by Expert Insights, we placed Ironscales in Office 365 enviroments that were already protected by a 3rd party email security service. We discovered that Ironscales successfully detected phishing emails that had evaded detection by Mimecast, Symantec & Microsoft ATP.
For suspect emails delivered to the mailbox, Ironscales allows users to report emails from within the inbox for further investigation. If the email is subsquently discovered to be a potential phishing email, the email can be deleted from any users who have received the email. This remediation and reporting puts Ironscales at a competitive advantage to other email security services that are unable to provide this functionality.
Using Ironscales, admins can set banners on emails, which alert users when an email is suspicious. If an email is reported as phishing, admins are alerted, and are able to remove the email entirely. This process can be fully automated according to admin policies.
Ironscales also provides a comprehensive Security Awareness Training platform, managed from one single admin console. It allows admins to send out simulated phishing email campaigns, and then provides users with engaging, gamified training materials, which help users to protect themselves against attacks such as phishing.
