When it comes to sending sensitive information, regular email is not a secure option. In this article, we explain why\u2014and how you can protect your communications.<\/span><\/p>\n<h3 class=\"p3\"><strong><span class=\"s2\">What information should not be sent by email?<\/span><\/strong><\/h3>\n<p class=\"p4\"><span class=\"s3\">All personal, identifiable, or financially sensitive information should be kept out of regular email unless you are using a secure method of communication. Examples of sensitive information include:<\/span><\/p>\n<ul class=\"ul1\">\n<li class=\"li4\"><span class=\"s3\">Personal identity codes, addresses, and health information<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">Passwords and usernames<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">Bank account and credit card information<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">Internal confidential company documents<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">Contracts and employee information<\/span><\/li>\n<\/ul>\n<p class=\"p4\"><span class=\"s5\">Rule of thumb:<\/span><span class=\"s3\"> Would you send this information on a postcard or in a sealed envelope? If your answer is in a sealed envelope, you should use encrypted email.<\/span><\/p>\n<h2 class=\"p3\"><span class=\"s2\">Why is regular email not secure?<\/span><\/h2>\n<h3 class=\"p4\"><strong><span class=\"s5\">Risks of unencrypted email:<\/span><\/strong><\/h3>\n<p class=\"p4\"><span class=\"s3\">Regular email is often transmitted over the internet without encryption. This means that the contents of your message can be intercepted, read, and even modified before they reach the recipient.<\/span><\/p>\n<h3 class=\"p4\"><strong><span class=\"s5\">Phishing attacks and email spoofing<\/span><\/strong><\/h3>\n<p class=\"p4\"><span class=\"s3\">Cybercriminals can easily spoof email addresses and send messages that appear to come from a trusted sender. Such messages may contain:<\/span><\/p>\n<ul class=\"ul1\">\n<li class=\"li4\"><span class=\"s3\">Malicious links<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">Attachments that install malware<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">Fraudulent requests to disclose confidential information<\/span><\/li>\n<\/ul>\n<h3 class=\"p4\"><strong><span class=\"s5\">The role of email service providers<\/span><\/strong><\/h3>\n<p class=\"p4\"><span class=\"s3\">Many free email services, such as Gmail, Yahoo, and Outlook, may analyse the content of your messages, for example to improve their services or for other purposes described in their terms of service. In addition, they do not provide automatic end-to-end encryption, which means messages may be more vulnerable to interception unless protected by other security measures.<\/span><\/p>\n<p class=\"p3\"><span class=\"s2\">The biggest email security risks<\/span><\/p>\n<ul class=\"ul1\">\n<li class=\"li4\"><span class=\"s3\">\u274c Messages are not encrypted \u2013 they can be intercepted in transit.<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">\u274c Email addresses are easy to spoof.<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">\u274c Phishing attacks are common.<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">\u274c Email service providers may analyse and use your data.<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">\u274c Emails are often sent to the wrong recipient by mistake.<\/span><\/li>\n<\/ul>\n<h3 class=\"p3\"><strong><span class=\"s2\">How can you protect your communications?<\/span><\/strong><\/h3>\n<p class=\"p4 translation-block\"><span class=\"s5\">Always use an encrypted email service<\/span><span class=\"s3\"> when sending sensitive or confidential information.<\/span><\/p>\n<h3 class=\"p4\"><strong><span class=\"s3\">Luottoposti provides:<\/span><\/strong><\/h3>\n<ul class=\"ul1\">\n<li class=\"li4\"><span class=\"s3\">Strong end-to-end encryption<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">A Finnish service that does not analyse the content of your messages<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">An easy and secure way to send and receive messages and attachments<\/span><\/li>\n<li class=\"li4\"><span class=\"s3\">Electronic signature functionality<\/span><\/li>\n<\/ul>\n<h3 class=\"p3\"><strong><span class=\"s2\">Summary<\/span><\/strong><\/h3>\n<p class=\"p4\"><span class=\"s3\">Email is a fast means of communication, but it does not provide sufficient security for handling sensitive information. Do not expose yourself or the recipient to unnecessary risks.
