Multiple forms of technology make up this email security solution to ensure email traffic is handled safely. Here&#8217;s how your email security gateways work to keep attacks at bay.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Spam_Filtering\"><\/span><a><\/a>Spam Filtering<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>This is perhaps the most important feature of a secure email gateway solution. This technology scans all incoming mail to your account. <\/p>\n\n\n\n<p>If it spots anything suspicious like abnormal image files or malicious URLs, The message never reaches an inbox and is sent to spam. Here, users will know not to interact with the message, which can be analyzed for potentially targeted threats.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Scans_Outgoing_Messages\"><\/span>Scans Outgoing Messages<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>An email security solution has to be ready for anything. If an account is compromised and spam is sent from a user&#8217;s account, this could mean big trouble for the recipients. <\/p>\n\n\n\n<p>However, a secure email gateway will scan outgoing messages for suspicious behavior. It will then block the malicious emails from reaching the intended recipients.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Prevent_Human_Error\"><\/span><a><\/a>Prevent Human Error<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>A secure email gateway can protect employees from making dangerous mistakes by removing the threat of malicious emails before they even hit a user&#8217;s inbox. <\/p>\n\n\n\n<p>It&#8217;s estimated that <a href=\"https:\/\/www.statista.com\/statistics\/1253129\/user-interaction-malicious-emails\/\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"2621\">3% of an organization&#8217;s employees<\/a> will click on malicious links. And it only takes one click and a few seconds for malware to be downloaded and infect a system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Gives_More_Control_to_Administrators\"><\/span><a><\/a>Gives More Control to Administrators<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>With a secure email gateway, administrators have greater power over what enters their email systems, allowing them to monitor and analyze incoming, outgoing, and internal emails. They have greater oversight to create reports on attacks and better manage security for their organization.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Does_It_Affect_How_People_Work\"><\/span><a><\/a>Does It Affect How People Work?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If you&#8217;re a leader in your organization, you want greater security to prevent sensitive data from being compromised by an attack. After all, cyberattacks come with <a href=\"https:\/\/www.nber.org\/digest\/jun18\/economic-and-financial-consequences-corporate-cyberattacks\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"2622\">serious financial consequences<\/a>. <\/p>\n\n\n\n<p>However, you may be concerned that blocking your gateway may interfere with employee productivity. But good news: your employees won&#8217;t notice the difference. Instead, they can work with confidence as they can worry less about potentially malware attachments, links, and emails.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"538\" src=\"https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/secure-email-gateway-benefits-nw1-1024x538.webp\" alt=\"Secure email gateway benefits\" class=\"wp-image-4233\" srcset=\"https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/secure-email-gateway-benefits-nw1-1024x538.webp 1024w, https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/secure-email-gateway-benefits-nw1-300x158.webp 300w, https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/secure-email-gateway-benefits-nw1-768x403.webp 768w, https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/secure-email-gateway-benefits-nw1.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Benefits_of_Secure_Email_Gateways\"><\/span><a><\/a>The Benefits of Secure Email Gateways<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Above are the key features of a secure email gateway, but what are the benefits, and why should you add this solution to your email security? <\/p>\n\n\n\n<p>No matter what server you have, Office 365, Google Workspace, or another platform, you can benefit from this added layer of security. Here are the top benefits you need to consider:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Protection_from_Inbound_Emails\"><\/span><a><\/a>Protection from Inbound Emails<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Multiple tools will be used to scan for malicious content when messages enter the gateway. The multi-layer filtration system functions as anti-phishing protection to ensure senders are who they claim to be, links or attachments aren&#8217;t suspicious, and the content isn&#8217;t a form of social engineering. <\/p>\n\n\n\n<p>From here, the message can be blocked entirely, held, or delivered but with alerts to users. This eliminates many of the threats posed by incoming traffic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Data_Loss_Prevention\"><\/span><a><\/a>Data Loss Prevention<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Data loss prevention is an important part of your digital messaging security. The threats may be coming from your employees&#8217; accounts. <\/p>\n\n\n\n<p>These insider threats come from hackers who gain access to accounts and send out sensitive data. By scanning outgoing messages, the messages are also stopped before they reach outsiders, functioning as an important data loss prevention solution.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Safe_Delivery\"><\/span><a><\/a>Safe Delivery<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Rather than blocking suspicious outgoing, your gateway system can scan for certain factors when emails go out. <\/p>\n\n\n\n<p>As a message is sent out, the sensitive data can be encrypted. This means that it can only be readable to authorized readers. While email servers like Office 365 provide good security, this added layer is necessary for any organization sending private information.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Archiving\"><\/span><a><\/a>Archiving<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Archiving emails is a quick and easy way to store messages with crucial information. However, storing this data within a messaging account may be dangerous. <\/p>\n\n\n\n<p>But with a secure gateway, you can worry less about these messages being at risk. Encrypted messages can remain encrypted, meaning even if it was mistakenly mailed out, the data won&#8217;t be accessible to just anyone due to the encryption and scanning from the gateway&#8217;s tools.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Kind_of_Email_Threats_Does_SEG_Prevent\"><\/span>What Kind of Email Threats Does SEG Prevent?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Even for well-known secure servers like Office 365, the platforms are still bombarded by cyber attacks. <\/p>\n\n\n\n<p>To ensure you have the right threat protection, you want to ensure you have solutions to meet all possible security challenges. Here are some of the most significant forms of attacks that this solution would protect against.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Phishing_Attacks\"><\/span><a><\/a>Phishing Attacks<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><a href=\"https:\/\/www.linux-wlan.org\/how-to-prevent-phishing-attacks\" data-type=\"URL\" data-id=\"https:\/\/www.linux-wlan.org\/how-to-prevent-phishing-attacks\" data-lasso-id=\"2623\">Phishing attacks<\/a> are social engineering attacks and are also one of the most common attacks. These social engineering attacks are usually incoming phishing emails. <\/p>\n\n\n\n<p>These are disguised as genuine communications but are meant to deceive a user into revealing sensitive information or downloading malicious software. However, a secure gateway can identify even sophisticated phishing attacks and keep them far from users&#8217; eyes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Business_Email_Compromise\"><\/span><a><\/a>Business Email Compromise<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>A business email compromise (BEC) attack is a form of spear phishing. Here, the attacker pretends to be someone that the user knows personally. <\/p>\n\n\n\n<p>They may pretend to be the employee&#8217;s boss, a vendor, or a middleman in a deal. The goal is typically to trick the user into sending money. But with a gateway that works closely to identify any suspicious activity, you can expect red flags on any BEC message.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"538\" src=\"https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/segs-simplified-im1-1024x538.webp\" alt=\"SEG definition\" class=\"wp-image-4237\" srcset=\"https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/segs-simplified-im1-1024x538.webp 1024w, https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/segs-simplified-im1-300x158.webp 300w, https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/segs-simplified-im1-768x403.webp 768w, https:\/\/www.linux-wlan.org\/wp-content\/uploads\/2022\/09\/segs-simplified-im1.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Is_Your_Service_Providers_Included_Gateway_Safe_Enough\"><\/span>Is Your Service Provider&#8217;s Included Gateway Safe Enough?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Any good email server like Office 365 or <a href=\"https:\/\/workspace.google.com\/intl\/en_uk\/\" data-type=\"URL\" data-id=\"https:\/\/workspace.google.com\/intl\/en_uk\/\" data-lasso-id=\"2624\" rel=\"noopener\">Google Workspace<\/a> will have some email security. For example, a spam filter will already be included, it may scan links and may give you an alert if a message is potentially dangerous. <\/p>\n\n\n\n<p>However, the security is fairly minimal compared to added tools available, leaving your system vulnerable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Who_Needs_a_Secure_Email_Gateway\"><\/span><a><\/a>Who Needs a Secure Email Gateway?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Do you want email security to keep your data safe? Are you concerned with risk management and want to keep any targeted attacks at bay? <\/p>\n\n\n\n<p>Then you need this security solution. Office 365 and Google Workspace users shouldn&#8217;t assume they&#8217;re safe. A strong gateway is the best way to block malware and keep threats away.<\/p>\n\n\n\n<p><strong>Bottom line:<\/strong> You only need a secure email gateway to keep hackers out and sensitive data private.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Cloud_vs_On-Premises_Appliance\"><\/span>Cloud vs On-Premises Appliance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Additionally, your email service depends on cloud-based email systems or on-premises hardware, you can find a gateway service to block email threats. <\/p>\n\n\n\n<p>Your cloud email environments still must be protected to ensure your email server isn&#8217;t subject to any attacker looking to barge in through malware. Cloud service is <a href=\"https:\/\/www.businessinsider.com\/cloud-technology-trend-software-enterprise-2021-2\" target=\"_blank\" rel=\"noopener\" data-lasso-id=\"2625\">becoming more popular<\/a> because it&#8217;s so secure, but you should still implement gateway security.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Happens_if_an_Attack_Breaches_Your_Gateway\"><\/span>What Happens if an Attack Breaches Your Gateway?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Your secure email gateway is meant to protect users and keep any attacks at bay, but it isn&#8217;t perfect. As mentioned at the beginning, there are other email security solutions that should be implemented alongside gateway protections. <\/p>\n\n\n\n<p>However, there are some tips to follow beyond these tools when suspicious messages breach your gateway.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Dont_Open_Messages_from_Senders_You_Dont_Know\"><\/span><a><\/a>Don&#8217;t Open Messages from Senders You Don&#8217;t Know<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>An important part of threat protection is treating every message with some skepticism. Any easy way of determining that a message is suspicious is whether you know the sender. <\/p>\n\n\n\n<p>If you can&#8217;t identify who it is, that&#8217;s an immediate red flag. Mark it for review by your anti-virus software or administrators and let them handle it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Avoid_Clicking_on_Suspicious_Links\"><\/span><a><\/a>Avoid Clicking on Suspicious Links<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>You open a message you think will be trustworthy, but the content is off, and there&#8217;s a link you can&#8217;t immediately identify. <\/p>\n\n\n\n<p>This could be hiding malicious files and email threats to your organization.
