Email Security

Detect and quarantine email-based attacks that bypass native controls in Microsoft 365 and Google Workspace, evade Secure Email Gateways, and slip through legacy tools.

Common Challenges With Email Security

Security awareness training and bannering can fail

Despite the best efforts of businesses to train their staff in security best practices, people can be rushed or overwhelmed and mistakenly open malicious emails and click links they shouldn’t. No context email bannering can lead to banner fatigue and may be useless for certain businesses.

Secure Email Gateways are imperfect

Secure Email Gateways (SEG) still require re-routing mail through the perimeter, forcing administrators to make and maintain DNS changes and MX records. Not only is this inconvenient, but it also requires ongoing maintenance as new domains are added.

Visibility and threat remediation is limited

SEG can lack visibility into internal email interactions that would allow for artificial intelligence to properly identify a suspicious message. Removing threats within the email environment can be difficult and administrators often lack visibility into user interactions with malicious messages.

How Can Rigid Bits Help Me Secure My Email Environment?

Rigid Bits leverages GreatHorn Cloud Email Security to provide our clients with the capabilities to address the many challenges that come with email threats. GreatHorn enables you to defend yourself with:

Dynamic banners that provide more specific messaging

Keep staff from suffering from banner fatigue with banner alerts that change in message and form to keep staff on their toes when threats are present.

In-the-moment security awareness training for suspicious emails

If someone still clicks a suspicious link, a link preview page can be leveraged to make sure the site they are about to visit is the one they expected. This slows down haphazard clicking, and additional messaging can help continue to educate the employee about possible threats.

Simplified remediation of malicious emails

Threats are visible and accessible to administrators as quickly as GreatHorn finds them. This means administrators are no longer solely relying on users to report emails, and it gives them the ability for bulk remediation of threats within seconds across the entire system. By avoiding the need to manually remove emails account by account, hours of effort can be saved.

Improved visibility for phishing email interaction

By existing beyond the email gateway and with deep inbox integration, GreatHorn can apply intelligent analysis to email threats. This allows for better identification of threats by determining if the user has communicated with a particular email address before, or if someone is suddenly sending from an email address that is unrecognized and potentially spoofed.

Advanced email security capabilities and customization

With best practices pre-loaded and easy to create policies that are specific to your organization, administrators can quickly adapt and tune GreatHorn to fit your unique business needs.

GreatHorn’s Key Features

GreatHorn has several features that are critical to the defense of your business and that differentiate it from other email security solutions:

  • GreatHorn’s Adaptive Threat Analytics uses machine learning and data science to quickly and automatically learn the communication patterns specific to each sender and recipient.
  • The strength of the sender’s relationship with the recipient is taken into account as well as the “friend of friends” system that measures the overall relationship with others in the organization.
  • Employee display name spoofs and domain look-alikes, including comparison against known email addresses, executive impersonation tactics, and email authentication standards, are analyzed to ensure the email is in fact from that sender.
  • Deep content information is analyzed based on keywords regular expressions (RegEx), attachments, and URLs, to identify common spear-phishing tactics.
  • Communication patterns are analyzed to identify what is unique to a specific individual and a specific organization, such as email frequency, volume, recipients, sending patterns and more.
  • Easy-to-understand and digestible warnings allow your employees to contribute to your organization’s security posture rather than detract from it with the right context at the right time.
  • Fully customizable smart banners containing specific instructions and context relevant to an individual email warn employees of specific threats and provide your end-users with insights into suspicious email to help them make better decisions.
  • Domain, context, as well as hundreds of other factors, are used to identify and block known malicious sites and provide previews of links deemed suspicious.
  • Reports are integrated directly into GreatHorn Email Security, so response teams can easily determine if the threat is real and quickly identify and remove other instances of an emerging attack.
  • GreatHorn’s incident response makes it easy to find and bulk remove threats from user inboxes in just seconds.
  • Automated Removal scans and removes any threats sitting in user mailboxes, even if a link is weaponized post-delivery.
  • Administrators are able to access full-click tracking for suspicious and malicious URLs, post-delivery blocking capabilities, and enhanced detection of new threats—even those that have not yet been added to real-time blacklists or publicly available antivirus tools.
  • A robust search engine enables you to search against any combination of factors from relatively simple content-based keyword searches to more technical metadata.
  • Two-Click Bulk Removal allows for an integrated incident response to search and remove bulk threats in seconds.
  • Empowers end users with education and options to take action from the front lines, further reducing your organizations’ susceptibility to email attacks.
  • Stop-light visibility into any sender and domain trustworthiness, relationship strength, and suspicious link warnings is provided to help users evaluate the risk within every email.
  • In-context notifications drive informed behavior by training your employees to recognize real-world phishing attempts and suspicious emails at the moment of risk.
  • “Report as Phish” capabilities enable your employees to easily report phish, remove spam, and even create personalized block lists to reduce unwanted mail.
  • Business Email Compromises (BEC) can allow for an attacker to intercept financial information or access sensitive information in saved emails. In many compromises, the attacker will send malicious files, links, or other phishing-based attacks to all past email correspondents.

  • The risk of account takeover has increased exponentially. Yet identifying compromised email accounts can be tricky – often showing up only after there’s been financial and reputational damage.

  • Implementing multi-factor authentication won’t protect users from cell-jacking, when a device has been left unlocked, or phone-based social engineering.

  • GreatHorn Account Takeover Protection leverages intelligence and tools to reduce the risk of compromised accounts and identify them faster by providing a low-friction, secondary layer of authentication that’s easy to implement, difficult to bypass, and minimally disruptive for employees.

Email security can be complicated, but it doesn’t need to be.
