Email security is a major concern for\nmost businesses, as it\u2019s often the weak point in their digital infrastructure.\nSome common email threats include eavesdropping, delivering malware through\nemails, address spoofing, phishing, etc. <\/p>\n\n\n\n<p>People continue to fall prey to these attacks and spam, with technology not being able to filter out every scam email. It is, therefore, of utmost importance that we actively participate in ensuring secure email communication. <strong>S\/MIME certificates (sometimes written as \u201cS Mime certificates\u201d)<\/strong> are a step in the right direction. With a Sectigo S\/MIME certificate, for example, you can sign all your emails and encrypt them both in storage and in transit. In addition to securing your data at all times, this certificate also ensures that no one can impersonate you because your emails are digitally signed. <\/p>\n\n\n\n<p>Let\u2019s take a closer look at what an S\/MIME\ncertificate is and how it works.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is S\/MIME Certificate?<\/h2>\n\n\n\n<p>RSA Data Security initially developed S\/MIME, or what\u2019s also known as secure\/multipurpose internet mail extensions. It\u2019s a protocol standard defined by the Internet Engineering Task Force (IETF) that enhances email security by allowing you to encrypt MIME data, aka emails. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Key Features of SMIME Certificate<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Industry-standard for public key\nencryption (asymmetric encryption) for MIME-based data.<\/li><li>Offers two key email security\nfunctionalities \u2014 digital signatures and encryption.<\/li><li>Digital signatures provide\nmessage integrity, authentication, and non-repudiation.<\/li><li>Encryption provides data\nconfidentiality (both for in-transit and at-rest data).<\/li><\/ul>\n\n\n\n<p>Because S\/MIME uses asymmetric public key\ninfrastructure (PKI), it employs two keys mathematically associated with each\nother to facilitates email security. By digitally signing your emails, the\nintended recipient can verify that the message was actually sent by you and hasn\u2019t\nbeen tampered with or modified. When the email is en route from your computer\nto the recipient&#8217;s device, data encryption ensures that any attacker over the\nwire can&#8217;t read the contents of the message.<\/p>\n\n\n\n<p>An SSL\/TLS certificate installed on your\nemail provider\u2019s helps to facilitate a secure communication channel between you\nand your email server. However, it doesn\u2019t encrypt your stored or archived\nemails, nor does it encrypt your emails in transit from other servers. Using an\nS\/MIME certificate on client agents does away with both these drawbacks. Note\nthat while SSL\/TLS certificates are installed on servers, S\/MIME certificates\nare installed on clients. Sectigo&#8217;s S\/MIME certificates can be automatically\ndeployed through a zero-touch deployment method into all mail clients.<\/p>\n\n\n\n<div class=\"graysection\"><h2>Buy Sectigo Email S\/MIME Certificate \u2013 Save 21%<\/h2>\n<p><strong>Save 21%<\/strong> on Sectigo Email S\/MIME Certificate.

The graphic below illustrates how\nasymmetric encryption works to encrypt and decrypt plaintext information.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"663\" height=\"255\" src=\"https:\/\/sectigostore.com\/page\/wp-content\/uploads\/2019\/11\/s-mime-certificate.png\" alt=\"The Mechanism of S\/MIME Certificate\" class=\"wp-image-1054\" srcset=\"https:\/\/sectigostore.com\/page\/wp-content\/uploads\/2019\/11\/s-mime-certificate.png 663w, https:\/\/sectigostore.com\/page\/wp-content\/uploads\/2019\/11\/s-mime-certificate-300x115.png 300w\" sizes=\"auto, (max-width: 663px) 100vw, 663px\" \/><\/figure>\n\n\n\n<p>Let&#8217;s understand how asymmetric encryption\nworks using an example.<\/p>\n\n\n\n<p>Consider that Ben wants to send an email to\nhis friend Jerry but does not want anyone else on the network to read or modify\nit. Ben uses Jerry&#8217;s public key to encrypt the message. Anyone can have access\nto this public key. Therefore, Ben or anyone can encrypt the message they want\nto send to Jerry. An intruder on the network cannot make sense of this message,\nthough, without the corresponding private key. The private key is only\naccessible to Jerry, so only he can decrypt and read the message. You can get\nan email signing certificate from a trusted certificate authority (CA) and use\nthis to digitally sign your messages (the certificate is automatically attached\nto the mail) before sending it off. The way this works is as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>A digital signature is\nassociated with two keys, a private key, and a public key.<\/li><li>Authentication is done using\nthe public key, whereas the private key is used to generate the signature\nitself. <\/li><li>The public key is sent along\nwith every protected email message to assert the identity of the sender. <\/li><li>The private key, on the other\nhand, generates and applies the unique digital signature to each email.\nSignatures verify that the message is unaltered and not tampered by an\nunauthorized third-party.<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Even though personal and business email communications are commonplace today, it continues to be one of the most vulnerable platforms in terms of security.
