Email Security- Why You Need It


Emails could well be the largest threat vector to your organization. What might seem like a harmless message in one of your employee’s inboxes may be the eventual cause of a massive credential leak, data leak, or full system compromise.

When Users Get Tricked By Phishing


Most companies only use the native email security tools built into popular email hosting services like Office365 and Google Workspace; however, it was found that

25% of phishing attacks were able to bypass Microsoft and Google’s native security tools.

Phishing, scams, and malware pose significant threats to your organization.

Email Security is every company’s first line of defense.

With an AI-based cloud email security platform, using industry-leading technologies and best practices, we can help you protect your organization from the full spectrum of email-initiated cyberattacks.

What is Email Security?

Emails are commonly used to spread malware, spam, and phishing attacks. Cyber security often focuses on weak links throughout the organization’s ecosystem but leaves the most vulnerable endpoint untouched. Email security is essential to protecting yourself, your workforce, and your data.

Your email security program must encompass end-user training, link inspection, DNS reputation, browser isolation, file attachment sandboxing, and 3rd party risk and breach notification. Just relying on native email security tools and training is not enough. No matter how hard we try, it is virtually impossible to train your most unsuspecting end users to outsmart the most sophisticated hackers every single time.

Are Emails a Security Risk?

Email is the primary way cybercriminals try to infiltrate organizations. On any given day, over 15 Billion (yes, Billion with a B) spam or phishing emails are sent. According to the FBI, about 30% of phishing emails are opened. What might seem like a harmless message can take down an entire organization. Poor email security can leave a vast vulnerability in your cyber security solution.

Having effective and defensive email security in place will:

  • Protect your organization from ransomware, spam, malware, and phishing attacks
  • Prevent theft or loss of data
  • Protect your brand and reputation
  • Save downtime responding to incidents

Email security too often relies on human responses and defensive action. However, with proactive technology, our email security approach can weed out malicious files and prevent phishing emails from entering your inbox in the first place.

First Line of Defense

Email platforms, beyond the native email security tools that come with your productivity suites, are essential for all businesses. They provide efficient and effective organizational communication that enables quick and easy conversation over various devices.


Emails do not go directly from the sender to the recipient. They travel between networks and servers—sometimes vulnerable and unsecured—before landing in the inbox. Anywhere along the email’s route, it might get compromised.

However, such far-reaching flexibility poses many risks for the organization, especially considering that emails often contain highly sensitive information. It is one of the most prominent targets exposed to attack.

How do you protect every user, every device, and every email account?

Types of Email Attacks


Cybercriminals pretend to be trusted individuals to steal sensitive information, like account numbers or login details. Phishing might target specific individuals or high-up employees.


Unsolicited messages sent in bulk to members of an organization. They might contain malware or ransomware or counterfeit and fraudulent messages. If nothing else, SPAM messages can bog down your inboxes and drive up storage costs.

Spearphishing & Spoofing

Attackers use a forged email address to attempt to fool recipients into thinking they are communicating with a known person.

Malicious Attachments

Attackers embed malicious payloads into common file types such as PDFs, excel docs, word docs, and more. Sometimes, when hackers gain access to a user’s machine, they will inject malicious payloads into the user’s ‘Recent Files’ to get the user to unwittingly send the compromised file.

Compromised Third Party

Using compromised accounts of legitimate businesses to attack companies they do business with.

Thread Hijacking

Hijacking active email conversation threads (via spoofing or 3rd party compromise) to embed an attack within an active conversation.

You need a comprehensive email security solution that stops malicious email attacks in their tracks. We’ll protect your email network to prevent breaches from occurring.

Email Security Solution Features

How can we protect your organization from email threats? Our proactive email security solutions use industry-leading technology and best practices to save you from damaging cyberattacks.

File Attachment Sandbox

Many email cyberattacks hide malware in file attachments. Too often, human error and untrained staff will open email attachments from unknown—or even supposedly known and trusted—parties. Even highly trained employees may accidentally open email attachments without thinking.

Scanning files for malware signatures is an outdated, useless practice that does little to protect your business. Instead, we deploy files in a sandbox with a sophisticated behavioral engine.

With this highly effective security defense, we can thoroughly investigate each and every email before hitting your inbox. Not only does this reduce the risk of human error, but it offers a comprehensive line of defense.

DNS Authenticity

DNS authentication uses several technologies to authenticate emails and allows domain owners to control who sends emails on behalf of their domains. DNS authenticity prevents spoofed domains, reputational irregularities, or hackers masquerading as internal employees from sending messages to your inbox.

Remote Browser Isolation

Remote browser isolation protects users from untrustworthy and potentially malicious emails or attachments by confining browser activity. Within a secured environment, malware cannot spread to other user devices or organizational networks.


How does remote browser isolation help?

Many email cyberattacks hide malware in file attachments. Too often, human error and untrained staff will open email attachments from unknown—or even supposedly known and trusted—parties. Even highly trained employees may accidentally open email attachments without thinking.

  • It averts MITM attacks
  • It prevents users from inputting sensitive information or credentials into login screens
  • It stops web attacks like drive-by downloads, malvertising, click-jacking, or web chopper shell

By isolating browser activity in a controlled environment, we can prevent browser-based cyber attacks from impacting your business.

Third-Party Risk


Untrusted Senders

Most of us know not to open emails and attachments from unknown and untrusted senders. But what do you do when a familiar sender’s company has been breached or hijacked? Third-party risks can increase the chances of a data breach or loss.


Email Security Solutions

Email security solutions filter incoming emails to detect harmful or compromised emails—even when they’re from a familiar sender. We can block third-party risks with high efficacy with a zero-trust approach, machine learning, and behavioral AI.
