Mail Assure email filtering overview dashboard

Protect your customers from email-borne threats with intelligent threat protection

Email is the perfect threat vector for hackers. Businesses often use unencrypted emails to share sensitive information on a day-to-day basis, and it doesn’t take much to trick someone into clicking on a malicious email and granting the hacker access. One email can compromise the entire network.

N-able® Mail Assure is a cloud-based hosted email security solution that gives you everything you need to protect your customers from email-borne threats. Mail Assure is powered by collective threat intelligence that incorporates data from over 23 million inboxes to help you stay on top of existing and emerging threats. The hosted email filtering service utilizes real-time pattern threat recognition to offer 99.999% filtering accuracy. With threat prevention this powerful, your customers will be better protected.

Easily verify senders using a hosted email security service with built-in email spoofing software

Email spoofing attacks are notoriously difficult to detect. Hackers design emails to look like they originated from a legitimate source, and sometimes the fraudulent address and the real address are only one character apart. The best way to detect business email compromise attacks and email spoofing is to verify all email senders.

Mail Assure features domain-based message authentication, reporting, and conformance (DMARC) to help prevent email spoofing when combined with sender policy framework (SPF) and DomainKeys Identified Mail (DKIM). SPF detects and blocks fraudulent emails, while DKIM signatures help ensure sender authenticity and verify that the email’s content hasn’t been modified. These hosted email security features empower your customers to use email with confidence.

Mail Assure - mailboxes query rules

Reduce risk and prevent your customers from clicking on compromised emails

Email filtering services are integral to email security. If you can eliminate or block suspicious emails before they get to your customers’ inboxes, it becomes that much easier to keep their data secure.

Mail Assure features advanced domain and filter settings that can be used to set checks, permissions, and spam scoring thresholds. For more control, you can also set custom filtering rules that apply to domains linked to a specific admin. The built-in quarantine management empowers users to view, release, block, and allow their own messages, giving them added control over their own email flow.

Hosted email filtering can also be used to protect your customers’ IP reputations. If users receive a lot of spam from a compromised address, they’re likely to lose trust in that organization. Integrated smart host deployment for outbound email filtering blocks any spam or viruses from leaving an organization, stopping spam before it can cause reputational damage.

Mail Assure general protection reporting continuity settings

Prevent data loss with secure email archiving and email continuity services

No hosted email security solution would be complete without email archiving and email continuity designed for security. In the event of a data breach, these two core aspects of hosted email security help prevent data loss, reduce risk, and maintain productivity in the event of an outage.

To keep your customers’ emails safe on a day-to-day basis, Mail Assure features robust AES and TLS encryption in transit and at rest. Journaling support makes it easier to pull emails from existing Microsoft 365 environments and reduces chain dependencies to help ensure your customers avoid missing an important email.

If service is down, Mail Assure will continue attempting to deliver mail and store emails in the incoming queue for two weeks. Also, full fallback MX service helps ensure emails are delivered once email service is up and running again.

Frequently Asked Questions

What is hosted email security and why is it important?

What is hosted email security and why is it important?

Hosted email security typically refers to a cloud-based email filtering service that’s provided by an established online security company or managed service provider.

To protect themselves against spam, a company creates an account with an MSP, adds their name and a domain administrator, then connects to the MSP’s servers by redirecting their MX records. From this point forward, incoming emails must first pass through the MSP’s servers and make it through the filtering protocols or policies set up by the domain administrator.

Many companies choose hosted email security because they can take advantage of enterprise-grade malware, ransomware, and spear phishing prevention without the hassle of managing it all themselves.

What is email spoofing?

What is email spoofing?

Email spoofing is a type of cyberattack in which a hacker forges an email header so that a malicious email looks like it originated from a legitimate source. To spoof an email, all a hacker needs is a working Simple Mail Transfer Protocol (SMTP) and an email service like Outlook or Gmail. Once the email message has been written, the hacker forges fields in the message header like the FROM and REPLY-TO addresses. After the fraudulent email is sent, it will look like it originated from a legitimate address.

Email spoofing is a popular tactic in phishing and spam campaigns because spoofs are difficult to detect, and people are much more likely to click on emails they believe to be from a trusted source.

How does threat intelligence work?

How does threat intelligence work?

Threat intelligence, also known as cyber threat intelligence, refers to any information an organization uses to better understand the threats that have affected, will affect, or are currently affecting an organization.

Threat intelligence solutions first pull raw data about existing or emerging threats from numerous sources like email inboxes. Then, the data is analyzed and filtered to produce actionable insights that can be used by hosted email security solutions and other tools. Threat intelligence information helps MSPs stay on top of the latest threats, build effective defense mechanisms, mitigate risk, and improve their customers’ cybersecurity.

How can I recognize a phishing or spear phishing email?

How can I recognize a phishing or spear phishing email?

To recognize a phishing attempt, MSPs and their customers should look for:

  1. Emails with a sense of urgency. Attackers typically evoke a sense of urgency to pressure the target into immediate action or exploit their desire to do something good.
  2. Grammatical errors. Phishing and spear phishing emails are infamous for containing grammatical irregularities. A spear phishing email will usually not read like other messages from the supposed sender. The tone might be too informal, the jargon might be incorrect, or some words could be misspelled.
  3. A spoofed email address. The email address will appear to be from a legitimate source, but upon close inspection, you’ll find typographic errors like an extra dash or letter that give the hacker away.
