Encryption of email is an essential element of any successful email security strategy or solution. It protects sensitive information shared via email such as financials, customer records and intellectual property, while preventing data loss. Unfortunately, many business email security companies fail to implement email encryption to its fullest, leaving users at risk and providing a false sense of security.
Email encryption involves encoding email messages in order to ensure that the content can only be read by intended recipients, preventing data leaks and breaches. Email authentication is an essential part of securing email messages with encryption, and can be implemented using SPF, DKIM and DMARC, three protocols that are highly effective in combating sender fraud. These sender authentication protocols secure email communications, and should be prioritized when evaluating a business email security solution.
Unlike many email security providers, Guardian Digital implements email encryption to its fullest - using SPF, DMARC and DKIM to build a secure tunnel between mail systems, providing complete end-to-end email protection. Guardian Digital EnGarde Cloud Email Security features multiple layers of advanced encryption technologies working harmoniously to secure email communications and prevent sophisticated attacks such as ransomware, spear phishing and business email compromise (BEC).
