Intelligent email security

Let PERNIX become your reliable first line of cyber defence that stands between your users and adversaries.

No user training or blaming

Eradicate the chance of human error

Protect against impersonation

Defend users from targeted attacks

Clear security visibility

Every email displays security indicators

Email is the single biggest attack vector, yet many businesses still rely on their users to identify fraudulent and malicious emails – this is both an impossible ask and dire business risk.

Remove the opportunity for users to make a mistake, by ensuring they’re never put in a position where they have to make a decision about the legitimacy of an email’s content, link, or attachment.

PERNIX stops email-borne attacks and warns users if an adversary is attempting to mislead, harvest credentials or spread malicious elements. Multi-layered defences use the latest intelligence to stay ahead of the evolving cyber threat landscape, as well as providing a secure email gateway and an intuitive fraud and spam guard.

Our intelligent email security solution gives the confidence and reassurance that your users can use email freely, without the risk or concern regarding email threats.

How it works



Download PERNIX email security datasheet

PERNIX is CORVID's email protection solution. It is a cloud-based mail gateway that seamlessly integrates into existing mail services, such as Mimecast, Office 365, Exchange, and the G-suite, as well as any existing on-premise email solution you have. Using advanced detection techniques, it identifies the good emails from the bad – quarantining those that present a security risk and delivering filtered, scanned emails to a user’s inbox with a simple traffic light categorisation to indicate how secure the email is, and whether we’ve identified any areas of concern they should be aware of.

Setup typically takes less than five minutes, as you only need to change two DNS records, MX and SPF. This allows IT admins to introduce a robust email security solution to your entire business, without any downtime or disruption to users.

Email security banner

The CORVID banner provides users with instant visibility of their security by displaying a simple traffic light header (red/amber/green), illustrating the nature and legitimacy of every inbound email.

From this banner, users are able to find out more about any highlighted areas of concern, and manage their emails. This is particularly important for fraud detection, or to check an email’s origin.

IT administrators are able to fully customise the banner’s warning messages, or disable it completely.

emails-dashboardEmail manager

Email manager is a user-friendly console that allows users to manage their emails and release those that have been blocked.

The interface provides a comprehensive overview for IT administrators of their email security – they can manage emails for all users, and view a plethora of reports showing traffic, trends, threat sources and geographical data.

Email manager is reached through the CORVID banner, accessible via a one-time access token link. This additional security layer removes the need for users to remember login details, and means there’s no need for IT admins to get involved.

CORVID portal

email-portal-screen-email-dashboardOur customer portal gives you a near real-time, centralised overview of your assets and data for each solution you’re subscribed to, through our secure, intuitive web interface.

The Email Protection dashboard shows details of blocked inbound emails, warnings issued, quarantine activity, and safe emails permitted through to your users’ inboxes. Emails are categorised by issues detected – such as malware or impersonation – and the world map shows the top ten sources of malware, enabling you to identify the type and volume of attacks your business is facing and where they’re coming from.
