Essentially, the company is responsible for ensuring that the server is equipped with appropriate security technology and that it is regularly maintained and updated.<\/p>\n\n\n\n<p>In addition, when new software is introduced, the company must ensure that the appropriate server capacity is available. For most companies, on-premise means that the server is physically located in the same location as the office and cannot be accessed from outside.<\/p>\n\n\n\n<p>So, even with the exponential rise of businesses moving to the cloud, here are some reasons why on-premise may still be a better fit for some companies.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button aligncenter is-style-fill\"><a class=\"wp-block-button__link has-vivid-red-background-color has-background\" href=\"https:\/\/www.mailsafi.com\/contact-us\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Get in touch for an on-premise mail server quotation<\/strong><\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_49 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"ez-toc-toggle-icon-1\"><label for=\"item-69e088482360e\" aria-label=\"Table of Content\"><span style=\"display: flex;align-items: center;width: 35px;height: 30px;justify-content: center;direction:ltr;\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/label><input  type=\"checkbox\" id=\"item-69e088482360e\"><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/mailsafi.com\/blog\/advantages-on-premise-mail-server\/#Advantages_of_On-premise_Email_Servers\" title=\"Advantages of On-premise Email Servers\">Advantages of On-premise Email Servers<\/a><ul class='ez-toc-list-level-3'><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/mailsafi.com\/blog\/advantages-on-premise-mail-server\/#1_Data_protection\" title=\"1.

The on-premises software can be maintained by your IT staff.&nbsp; You can decide on the software upgrades, security of your email, and hardware configurations.<\/p>\n\n\n\n<p>Some companies like banks, hospitals hold sensitive data in email. Therefore, if the customer policies demand that you retain complete control of your data, an on-premise email solution may be preferred. You will be safer with the notion that your customer data sits behind an internal firewall.<\/p>\n\n\n\n<p>Most cloud-based email hosting services use what&#8217;s called multi-tenancy. Basically, the servers hosting your emails also hold other companies&#8217; emails. With proper security, this isn&#8217;t an issue. User access can be strictly controlled. Communication between virtual servers running on the same host is isolated.<\/p>\n\n\n\n<p>However, security isn&#8217;t always perfect. Automation can go wrong, configurations can be misapplied, or vulnerabilities allowing guest VMs direct access to the host can go public (<a href=\"https:\/\/www.networkworld.com\/article\/3187778\/critical-xen-hypervisor-flaw-endangers-virtualized-environments.html\" target=\"_blank\" rel=\"noreferrer noopener\">this has happened before<\/a>).<\/p>\n\n\n\n<p>Few dedicated email hosts are not going to be multi-tenancy, though, so if you want to avoid it completely, running your own mail server is the only reasonable option. Because data is stored locally on your premises, you have full control over it and its security. Your own data, and possibly also customer data, is not stored on the server at another company. This means that confidential or sensitive data does not need to leave your company \u2013 a condition required by some industry regulations.<\/p>\n\n\n\n<h3 class=\"has-vivid-red-color has-text-color has-medium-font-size wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Local_storage\"><\/span>2. <strong>Local storage<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If network problems occur and the connection to the internet is interrupted, your employees can still access the data with on-premise solutions.<\/p>\n\n\n\n<p>If you would like to consider a <a href=\"https:\/\/www.mailsafi.com\/business-email-hosting\" target=\"_blank\" rel=\"noreferrer noopener\">cloud-based email hosting solution<\/a>, please check out our blog here for <a href=\"https:\/\/mailsafi.com\/blog\/benefits-of-cloud-or-hosted-email\/\" target=\"_blank\" rel=\"noreferrer noopener\">the advantages of cloud-based email services<\/a>.<\/p>\n\n\n\n<h3 class=\"has-vivid-red-color has-text-color has-medium-font-size wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_A_one-time_investment_capital_investment_on_the_mail_server\"><\/span>3. <strong>A one-time investment capital investment on the mail server<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>There are no ongoing software costs. With on-premise servers, the software is usually purchased outright. It is a one-time capital investment. This works better for some business models. It can also be cheaper to operate after the initial investment in the server. Also, with an on-premise email server, you never have to worry about your email accounts being suspended abruptly for non-payment.<\/p>\n\n\n\n<h3 class=\"has-vivid-red-color has-text-color has-medium-font-size wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_You_can_make_backups_according_to_your_preferred_frequency_and_schedule\"><\/span>4. <strong>You can make backups according to your preferred frequency and schedule<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Because you are in control of your email server, you can take backups according to your requirements \u2013 schedule and frequency \u2013 to meet your exact company policies.

If you&#8217;ve already invested in&nbsp;setting up a data center, then it makes more financial and business sense to proceed with an on-premise mail server than opt for a monthly subscription.<\/p>\n\n\n\n<p>Why? Because the main benefits and selling points of moving your email to the cloud is scale and uptime, i.e., you can take advantage of your third-party <a href=\"https:\/\/mailsafi.com\" target=\"_blank\" rel=\"noreferrer noopener\">email service provider&#8217;s<\/a> huge capacity and redundancy to guarantee performance and uptime.
