As of this year, Microsoft 365 (formerly Office 365) has grown to more than 345 million paid subscribers, and businesses continue to use the platform, with its commercial base now topping 440 million seats worldwide. But as those subscription numbers keep climbing, Microsoft 365 becomes an even bigger target for cybercriminals looking to spread phishing, ransomware, and a new wave of AI-generated attacks.
A big drawback of such a large hosted service is that if cybercriminals manage to take over just one account, they can use it to launch thousands of phishing attacks. And because those messages are sent from a legitimate Microsoft 365 account, they’re far more likely to slip past Microsoft’s Exchange Online Protection (EOP) and Microsoft Defender for Office 365 (the service formerly known as Advanced Threat Protection).
To combat these growing threats, businesses are turning to third-party email security gateways, and there are plenty of them out there with a relatively standard set of anti-spam and anti-phishing features. So to stand out from the competition, a solid email filtering solution has to be easy to use while delivering extra capabilities such as archiving, compliance, and reporting, and, increasingly, the AI-driven detection it takes to catch the more convincing scams landing in inboxes today.
For businesses on Microsoft 365, SecurityGateway offers stronger protection against email-borne threats, with account-verification controls built specifically for Microsoft 365 to make sure only authorized users are permitted to send or receive email.
More than just spam & phishing protection - archiving & compliance, too!
Of course, SecurityGateway does much more than protect your users from spam & phishing. It also includes built-in archiving with retention policies and legal hold for businesses that have to meet compliance regulations, or that simply want a backup & recovery solution for a little peace of mind in the event of an outage or security breach.
SecurityGateway also includes Data Leak Prevention (DLP) to keep sensitive business data such as Social Security Numbers, Tax-ID Numbers, banking info, and much more from getting into the wrong hands. Messages containing confidential data can be encrypted using the built-in email encryption options, or routed to the administrative quarantine for further review. After all, it only takes a quick search to turn up a long list of companies that have suffered steep fines, lost customers, and a damaged reputation after sensitive data was exposed.
