Here\u2019s Your Ultimate Guide!"},"content":{"rendered":"\n

A secure email certificate, also known as an S\/MIME certificate\nor an email signing certificate, is used by anyone who sends emails for\nbusiness-related purposes that contain sensitive information. It\u2019s widely used\nby small businesses, SMBs, and large corporations because it does two extraordinary\nthings: <\/p>\n\n\n\n

  1. It attaches a digital signature to the email\nthat verifies that you (and not an imposter) sent the email, and that the email\nhasn\u2019t been altered since it was sent. <\/li>
  2. It encrypts your emails before they ever leave\nyour mailbox so they can only be opened by your intended recipients. This\nprovides both data in-transit and data at-rest protection.<\/li><\/ol>\n\n\n\n

    Let’s understand each of the above-stated functions in\ndetail.<\/p>\n\n\n\n

    A Digital Signature Warns Users Whether an Email Has Been Altered<\/h3>\n\n\n\n

    When you install a secure email certificate on your email server\n(such as Microsoft Outlook, Apple Mail, Mozilla Thunderbird, etc.), it\nautomatically attaches your digital signature to all of your outgoing emails.\nThis digital signature is encrypted and produces a unique hash value. If anyone\ntries to alter this digital signature, the hash value changes. This warns the\nsender and recipient that something about the email is fishy. <\/p>\n\n\n\n

    Essentially, the encrypted digital signature assures the\nrecipient that your email is valid, and it was sent by you\/your company and is\nnot a phishing email. <\/p>\n\n\n\n

    End-to-End Email Encryption: Protects Data in Transit and At Rest  <\/h3>\n\n\n\n

    End-to-end email encryption means that your emails are\nprotected from one end of the transaction to another. This means that before\nyou even hit \u201csend,\u201d your email is encrypted. A secure email certificate\nencrypts the entire content of the email until the email reaches the intended\nrecipient\u2019s inbox and is decrypted. So, if anyone breaks into the email\nnetwork, all they would see is a bunch of random numbers and letters, which won\u2019t\nbe of use to them! That\u2019s because the actual message can be decrypted and read only\nby the intended recipient through the use of public key encryption. <\/p>\n\n\n\n

    In other words, a secure email certificate helps to ensure\nthat your email contents arrive in the same condition as they were sent.\nNothing is added, deleted, or altered while the email was in the transit.<\/p>\n\n\n\n

    If both the sender and recipient have installed a secure\nemail certificate on their individual endpoints, all the signed emails stored\nand archived on the recipient\u2019s email server also stay encrypted. <\/p>\n\n\n\n

    Why Email Encryption Matters <\/h2>\n\n\n\n

    Okay, so encrypting your email and signing it with a digital\nsignature sounds great. But what\u2019s the real value to your organization? There\nare three crucial reasons as to why you should install a secure email\ncertificate on your endpoint devices:<\/p>\n\n\n\n

    Protect Your Organization\u2019s Reputation<\/h3>\n\n\n\n

    It\u2019s commonly said that you only get one chance to make a\nfirst impression. The same can frequently be said about an organization\u2019s\nreputation. A data breach or other cybersecurity issue can result in costly\nreputational damage for your organization. And once you lose that trust \u2014 well,\nit\u2019s\nhard to get it back<\/a>. <\/p>\n\n\n\n

    It\u2019s a common phishing practice to insert harmful scripts,\nlinks, and other sorts of dangerous malware into emails. When cybercriminals\nget access to any company’s email network, they use authentic emails sent by\nthe authorize employees and corrupt them. The recipient thinks that the email was\nsent by a trusted organization. As a result, they open the email, click on the\nlink, download the attachment, fill out the form, or share confidential\ndetails. That’s how they become the victim of various cybercrimes.  <\/p>\n\n\n\n

    On the other end, you \u2014as the business organization \u2014 have\nno clue about it, and yet your reputation is getting harmed as a result. <\/p>\n\n\n\n

When you click on that ribbon icon, you\nwould see a window assuring the authenticity of the sender and the content of\nthe email.   <\/p>\n\n\n\n
