    What is email security software?


    Email security is a phrase used to describe the need to adopt different techniques and procedures to protect your email accounts, computers, and content against loss and unauthorised access.

    Email is a common way to spread spam, malware, and phishing attacks. In response, email security software allows companies to protect their email addresses from data leaks and email threats.

    Is free email security software any good?

    We’ve put together a list of available security features that email security software tends to offer:

    • Minimise phishing attacks

    • Analyse and filter all incoming emails to block suspicious content

    • Some email security software is cloud-based

    • Options available to prevent data loss

    We’ve also put together a list of email security software that is free to use for the user.


    Mailcleaner states that their software gets rid of approximately 95% of spam and viruses. Offering a gateway to protect your inbox, Mailcleaner is free, high-quality, and easy to install.


    Scrollout software has multi-layer security levels that are easy to use. Not only does it include security features, but it will also deploy spam traps and verify the sender’s IP address.

    Promox Mail Gateway

    This email security software is designed to be incredibly user-friendly, and they claim that they take care of every threat, including phishing, Trojans, spam, and viruses, for free. How? A mail proxy is installed to control all the emails from one platform.

    Comodo KoruMail

    KoruMail is a threat prevention and anti-spam appliance that you can use free of cost. It uses spam filters and content scanners to get rid of suspicious emails from even getting into your network.

    As you can see above, there is a wide selection of free email security software available for you to access and use. So, you can add a layer of protection to your emails. Ultimately, however, a paid email security software will offer more security features than a free one. It’s up to you to decide which option is most feasible for you by considering your demand and budget.
