What we hear





We need to protect end users from email threats
We need to protect end users from email threats
Email is now a primary attack vector and MSPs’ clients are relentlessly bombarded by threats. It’s difficult and unrealistic to expect end users to out-think every attack.

Our clients expect 100% email uptime
Our clients expect 100% email uptime
MSPs’ clients run on email with little room for downtime or compromise. Missed emails are missed opportunities, and loss of business will reflect on—and affect—MSPs.

Rule-based filtering is just not enough
Rule-based filtering is just not enough
Spammers change strategies all the time. Rule-based filtering simply can’t keep up, so we need a solution that can evolve as quickly as the threats that are plaguing our end users.

Our MSP is a target for cyberattacks
Our MSP is a target for cyberattacks
MSPs are obvious targets and need to protect their internal systems, too. With a successful attack, cybercriminals could otherwise gain access to their clients’ data and communications.

Email compliance requirements are increasing
Email compliance requirements are increasing
Legal, government, and medical clients are often required to archive and retain email for years. Nobody wants unhappy surprises when data retrieval or recovery is not possible.

“With Mail Assure, we were able to solve the security problem as well as the problems of distrust of our servers, so that it keeps us our emails in this period.”
Protect inboxes from hackers by incorporating secure techniques
How are you keeping your clients safe from receiving forged emails? If your email provider cannot detect that the email is not valid, then it is only a matter of time before a hacker gets a foothold into our clients’ inboxes, and their networks are next. Through the Mail Assure administration console, you can turn on authentication techniques, like Domain Keys Identified Mail. Another way to dial up the protection is encrypting email messages in transit using SSL/TLS protocols.
