It\u2019s used every day in the corporate world, and you can only imagine the steady stream of sensitive information that\u2019s involved. That\u2019s why understanding best practices for email security is crucial.<\/span><\/p><p><span style=\"font-weight: 400;\">From individual device protection to the whole of your <\/span><a href=\"https:\/\/www.firewalls.com\/blog\/network-security-tools\/\"><span style=\"font-weight: 400;\">network security architecture<\/span><\/a><span style=\"font-weight: 400;\">, email is a part of the discussion.

With things like financial data, client info, and proprietary information, it doesn\u2019t take much to do some damage. Even if it\u2019s just a single email, that\u2019s all many attackers need to gain access to many other parts of the network. Below, you\u2019ll find other leading reasons as to why advanced email security matters for modern businesses.<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Emails are commonly exploited as entry points for large-scale attacks<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Financial impact can range from fraud, long-term recovery costs, and ransomware<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Breaches can lead to regulatory fines and issues with data security compliance<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Compromised emails can harm reputations and put jobs at risk<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">Secure networks are a must, far outside of the scope of emails alone. However, considering they\u2019re a common entry point for bigger security issues, it\u2019s highly advised to utilize the best email security possible. Of course, this is a layered approach, and there\u2019s no single solution that\u2019ll guarantee your business emails are protected.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-aa47ea7 elementor-widget elementor-widget-heading\" data-id=\"aa47ea7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Must-Have Business Email Security Best Practices\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-81ce9df elementor-widget elementor-widget-text-editor\" data-id=\"81ce9df\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">There\u2019s plenty you can do to keep company emails secure, but it\u2019s helpful to remember that changing technology comes with shifting security norms. Nevertheless, you can\u2019t go wrong with multi-factor authentication, third-party solutions, or a layered network architecture. The best practices below offer a combined approach to cyber-attack prevention, and they consider more than just passwords and two-factor logins.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f085d2d elementor-widget elementor-widget-heading\" data-id=\"f085d2d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">1.

With the help of standardized patch management, you can support consistent protection across your entire organization. The scope of the updates you should focus on can include applications, servers, and endpoint devices that tie into your business emails.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5c56247 elementor-widget elementor-widget-heading\" data-id=\"5c56247\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">2.

A good example of where you can find this is in <\/span><a href=\"https:\/\/www.firewalls.com\/brands\/sonicwall\/email-security.html\"><span style=\"font-weight: 400;\">SonicWall\u2019s email security solutions<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p><p><span style=\"font-weight: 400;\">It isn\u2019t just surface-level security measures you already have access to. These solutions focus on every layer of email security, from email appliances, data-loss prevention, multi-tenant security, and the list goes on.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2c4ee9b elementor-widget elementor-widget-heading\" data-id=\"2c4ee9b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">3.

For example, it\u2019s a good idea to disable auto-forwarding. This is a preventative measure for attackers aiming to redirect sensitive emails.<\/span><\/p><p><span style=\"font-weight: 400;\">Outside of that, you can also utilize spam filters and domain authentication protocols like DKIM and DMARC, for example. You can effectively block a lot of phishing scams and spoofing this way, not to mention what encryption can do for you here. With necessities in compliance, email encryption should be a given, as it ensures any intercepted emails remain unreadable.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-92255a5 elementor-widget elementor-widget-heading\" data-id=\"92255a5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">4.

Every internal password should include more than just letters, such as a variety of special characters. It\u2019s also helpful to utilize password managers. These can generate new logins at random and keep them stored behind an added layer of security.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">MFA is there just in case those passwords are compromised. Moreover, this particular measure can be combined with your network security architecture to further mitigate compromising situations.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-255c983 elementor-widget elementor-widget-heading\" data-id=\"255c983\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">5.

External threats aren\u2019t always the issue. Sometimes, an internal mistake can lead to a business-wide network risk that can get out of control.<\/span><\/p><p><span style=\"font-weight: 400;\">Staff should be able to identify phishing attempts, considering they\u2019re so common, in addition to suspicious attachments or added links. It only takes a single click for a network threat to snowball, and this can all stem from a single employee\u2019s mistake.<\/span><\/p><p><span style=\"font-weight: 400;\">Secure networks are made up of multiple layers, <\/span><a href=\"https:\/\/www.firewalls.com\/brands\/barracuda-networks\/email-security.html\"><span style=\"font-weight: 400;\">services, and tools<\/span><\/a><span style=\"font-weight: 400;\">. Between software and hardware support, the best email security starts with internal management of the situation. Another angle to consider is the rising prevalence of AI, which will inevitably lead to email security best practices adapting again over time.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2ff3ed8 elementor-widget elementor-widget-heading\" data-id=\"2ff3ed8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">The Final Word\n<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7933af3 elementor-widget elementor-widget-text-editor\" data-id=\"7933af3\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Email will always be a critical component of the business world.
