Gain Email Security with Managed Services for Microsoft Office 365

Complex targeted attacks and malware are no longer reserved purely for big business. All companies are increasingly tested by the rising levels of sophisticated, malicious emails and social media posts.

External threats come into your business through common communication channels including email and social media. You need an email security solution that protects your company from all email threats including phishing, malware, spam, and other forms of bad content.

You can protect your incoming and outgoing email through endpoint security protection. Additionally, steps for remediation should be put in place to deal with the unlikely event of a successful attack. Choose an email security solution that can stop malware and non-malware threats such as imposter email (also known as business email compromise).


The Importance of Filtering

Your email security solution should have filtering capability and business continuity features. Email filtering provides real-time spam and virus filtering while blocking attacks and monitoring traffic. Messages can be approved or blocked automatically within seconds based on sender, origin IP address, attachment size, file type, or text content. Filtering ensures that trustworthy emails are delivered with minimal delay while suspect messages are blocked or quarantined.

Using Microsoft Office 365

If you’ve already recognized that you need robust email security for your business — congratulations. Maybe you’ve decided to migrate to Microsoft Office 365 and are evaluating the security options within the various Office plans. Many Office 365 customers find they need more advanced security capabilities than are available natively with Office 365, Microsoft's cloud based email and collaboration platform.

Filtering Alone is Not Sufficient

Microsoft provides only basic email security features, relying on traditional filtering techniques such as IP reputation, volume, and signature based antivirus scans. Unfortunately, the security features available within Office 365 do not provide the advanced security capabilities needed to stop phishing attacks. Corserva’s managed services solution for email security is more effective than Office 365 alone in blocking spam, viruses, and malicious content from attachments and hyperlinks.

Improved Email Security at a Value Price

Corserva’s solution also automatically detects and secures sensitive information leaving the organization.

Using the Microsoft Office 365 Enterprise E1 plan as part of Corserva’s managed email security service provides the greatest value; for less than the cost of an E3 or E5 plan, you gain better security than what is provided by the higher end Office 365 plans at a cost that is only slightly more than an E1 plan.
