The VPN creates an <a href=\"https:\/\/www.privateinternetaccess.com\/vpn-features\/vpn-encryption\">encrypted tunnel <\/a>between your device and that network, allowing safe access to files, applications, and other internal resources without needing to be physically on-site.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-when-do-you-need-a-remote-access-vpn\">When Do You Need a Remote Access VPN?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You need a remote access VPN any time you or your team must securely connect to a private network from outside its physical location. It\u2019s especially useful for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Employees working remotely: <\/strong>Access company files, internal tools, and shared drives without exposing sensitive data.<\/li>\n\n\n\n<li><strong>Frequent travelers: <\/strong>Connect to the company network from hotels, airports, or public Wi-Fi spots securely.<\/li>\n\n\n\n<li><strong>Contractors or partners needing access: <\/strong>Allow temporary and secure access to specific systems without exposing the entire network.<\/li>\n\n\n\n<li><strong>IT staff managing systems off-site:<\/strong> Manage infrastructure from anywhere without risking security.<\/li>\n\n\n\n<li><strong>Organizations under compliance requirements:<\/strong> Protect data by encrypting remote connections to meet industry regulations.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-does-a-remote-access-vpn-work\">How Does a Remote Access VPN Work?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2400\" height=\"1690\" style=\"margin-bottom: 15px; margin-top: 15px;\" src=\"https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/how-remote-access-vpns-work-min.png\" alt=\"Infographic showing three stacked steps of how a remote access VPN works: verifying identity, encrypting traffic, and creating a secure tunnel.\" class=\"wp-image-33043\" srcset=\"https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/how-remote-access-vpns-work-min.png 2400w, https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/how-remote-access-vpns-work-min-300x211.png 300w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">All remote access VPNs follow the same core principles:\u00a0<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>They verify your identity before letting you in.<\/li>\n\n\n\n<li>Encrypt your traffic so no one else can read it.<\/li>\n\n\n\n<li>Create a secure tunnel between you and the <a href=\"https:\/\/www.privateinternetaccess.com\/vpn-server\">VPN server<\/a>.\u00a0<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">From that point forward, everything you send and receive travels through the tunnel, encrypted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">How you connect can vary depending on the setup. Some VPNs require a special app or client, while others work right from your browser or can be configured manually through your operating system. Here\u2019s how each method works:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2400\" height=\"2082\" style=\"margin-bottom: 15px; margin-top: 15px;\" src=\"https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/ways-to-connect-to-a-remote-access-vpn.png\" alt=\"Infographic titled \u201cWays to Connect to a Remote Access VPN\u201d showing three side-by-side choices: a VPN app, a browser login, and manual setup.\" class=\"wp-image-33034\" srcset=\"https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/ways-to-connect-to-a-remote-access-vpn.png 2400w, https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/ways-to-connect-to-a-remote-access-vpn-300x260.png 300w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-using-a-vpn-client\">1. Using a VPN Client<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is the standard way most people connect. You <a href=\"https:\/\/www.privateinternetaccess.com\/buy-vpn-online\">install a VPN app<\/a> that handles everything for you, then simply open it and connect to encrypt all your network traffic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re an employee, your IT team gives you the app (or download link) plus your login and MFA; if you\u2019re a freelancer\/contractor, your client sends the same.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You\u2019ll usually need to <a href=\"https:\/\/www.privateinternetaccess.com\/vpn-features\/dedicated-ip-vpn\">get a dedicated IP address<\/a>, so you\u2019re always signing in with the same IP. On their end, this IP address is usually added to an allowlist: a list of IP addresses that can access the company\u2019s systems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-using-a-browser-based-vpn-no-client-needed\">2. Using a Browser-Based VPN (No Client Needed)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some VPNs, especially those based on SSL\/TLS, can run entirely in your web browser. You just visit a secure login page (like https:\/\/vpn.company.com), enter your username and password, and you\u2019re in.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The company (or client, if you\u2019re freelancing) simply sends you that URL, your credentials, and any MFA steps. This is zero-install and quick to grant to contractors, but it usually only gives you access to certain company web apps or portals inside the browser<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-manually-configured-vpn-via-built-in-tools-in-your-os\">3. Manually Configured VPN (Via Built-in Tools in Your OS)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If no client is provided, and you need more than browser access, most operating systems allow you to set up a VPN manually using built-in tools. You\u2019ll need a server address, your credentials, and sometimes certificates or pre-shared keys.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those details come from the company\u2019s IT department or your client provides them, often as a small config pack (e.g. a profile or .ovpn file) or a short step-by-step guide for your OS. Once set up, the connection works like a client-based VPN and gives you fuller network access without installing a separate app.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pros-and-cons-of-a-remote-access-vpn\">Pros and Cons of a Remote Access VPN<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Pros of Remote Access VPN<\/strong><\/td><td><strong>Cons of Remote Access VPN<\/strong><\/td><\/tr><tr><td>\u2705 Data is protected with authentication and encrypted tunnels, even on public Wi-Fi.<\/td><td>\u26a0\ufe0f Performance hits: Potential slowdowns when many users log in simultaneously.<\/td><\/tr><tr><td>\u2705 Uses the public internet, avoiding expensive private circuits.<\/td><td>\u26a0\ufe0f Single point of failure: If the VPN server goes down, access is lost.<\/td><\/tr><tr><td>\u2705 Works across different devices and operating systems without extra hardware.<\/td><td>\u26a0\ufe0f Limited device visibility: IT can\u2019t always ensure personal devices are patched and secure.<\/td><\/tr><tr><td>\u2705 Centralized IT control: IT sets rules, enforces authentication, and monitors in one place.<\/td><td>\u26a0\ufe0f Hard to scale: Managing thousands of users and all their traffic through one gateway creates bottlenecks.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tor\">Types of Remote Access VPN Connections\u00a0<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Remote access VPNs rely on a few main technologies to build secure connections. While all of them aim to protect data and verify user identities, they work a little differently under the hood. Here\u2019s a breakdown of the <a href=\"https:\/\/www.privateinternetaccess.com\/blog\/beginners-guide-to-vpn-encryption-protocols\/\">major security protocols<\/a> used for securing your data:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Category<\/strong><\/td><td><strong>IPSec<\/strong><\/td><td><strong>SSL\/TLS<\/strong><\/td><td><strong>OpenVPN<\/strong><\/td><td><strong>WireGuard<\/strong><\/td><\/tr><tr><td><strong>Best for<\/strong><\/td><td>Always-on, full-device protection<\/td><td>Quick access to a single web app\/portal<\/td><td>VPN access on almost any system<\/td><td>Individuals or small-team use that need a fast VPN<\/td><\/tr><tr><td><strong>What it protects<\/strong><\/td><td>Entire device (all traffic and apps)<\/td><td>Just one app\/browser session<\/td><td>Entire device or selected apps<\/td><td>Entire device or selected apps<\/td><\/tr><tr><td><strong>Speed<\/strong><\/td><td>Stable, but slower compared to newer options<\/td><td>Very fast, since it only protects one app<\/td><td>Reliable but heavier, can slow things down<\/td><td>Extremely fast<\/td><\/tr><tr><td><strong>Ease of use<\/strong><\/td><td>Needs setup by IT\/admin, then runs quietly<\/td><td>No setup required: just use your browser<\/td><td>Requires installing a VPN app and some config<\/td><td>Needs a VPN app, but setup is very straightforward<\/td><\/tr><tr><td><strong>Where you\u2019ll see it<\/strong><\/td><td>Corporate laptops, always-on work VPNs<\/td><td>Logging into company portals or banking sites<\/td><td>Remote workers, hobbyists, open-source fans<\/td><td>Newer VPN services, tech-savvy teams, personal devices<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-ipsec\">IPSec<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">IPsec is one of the oldest VPN protocols. It works at the network layer, meaning it protects all traffic between your device and the VPN, not just specific applications. To do that, it uses strong encryption methods like AES and works alongside a protocol called IKEv2, which handles key exchange and authentication, making sure you\u2019re really who you say you are before granting access.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-ssl-tls\">SSL\/TLS<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">SSL\/TLS-based VPNs are often easier to use than IPSec. They usually run through your web browser or a lightweight app and use the same technology that secures websites (HTTPS). You may want to use it if you just need access to certain apps or services without routing all your traffic through the VPN.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-openvpn\">OpenVPN<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">OpenVPN is an open-source protocol with a high level of security. You\u2019ll typically need to install a VPN client to use it, but it\u2019s highly configurable and compatible with many devices and operating systems. It uses <a href=\"https:\/\/www.privateinternetaccess.com\/vpn-features\/vpn-encryption\">strong encryption<\/a> (including the military grade AES 256-bit), and can work in places with tough network restrictions and firewalls, if configured properly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-wireguard\">WireGuard<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.privateinternetaccess.com\/blog\/wireguide-all-about-the-wireguard-vpn-protocol\/\">WireGuard<\/a> is a newer VPN protocol built for speed and simplicity. It has a significantly smaller codebase compared to other protocols, which makes it easier to audit for vulnerabilities and less likely to have bugs or other issues. This also helps it run faster than other protocols, plus it connects almost instantly.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ravs\">Remote Access VPN Security Risks and Best Practices<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Even if you use a VPN, your remote connection can still have hidden security gaps. Here are the most common security risks, and what you can do to mitigate them.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-network-wide-access\">Network-Wide Access<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional VPNs grant users full network access once connected. Without granular control, users might reach systems they shouldn\u2019t.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How to fix it:<\/strong> Follow the least privilege principle, and only allow users access to the specific tools or data they need for their job. You can also use role-based access control (RBAC) to set permissions based on job roles. For better security, consider switching to a <a href=\"#ztn\">Zero Trust Network Access (ZTNA) model<\/a>, which gives users access only to individual apps.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-weak-remote-environments\">Weak Remote Environments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If an employee\u2019s laptop, phone, or tablet is infected with <a href=\"https:\/\/www.privateinternetaccess.com\/blog\/how-to-prevent-malware\/\">malware<\/a>, that threat can pass straight through the VPN tunnel into the company network. Even if devices are secure, most home networks lack enterprise-grade firewalls or monitoring, which makes it easier for attackers to slip in.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How to fix it:<\/strong> Require team members to keep operating systems updated, as well as their routers and Wi-Fi networks. They may need to use reliable antivirus software on all devices used for work, and enable any built-in VPN security features like DNS or malware blocking.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-central-vpn-bottleneck\">Central VPN Bottleneck<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Remote workers usually connect to a central VPN server or server managed by the company. If that server fails, crashes, or is attacked (for example, with a Distributed Denial of Service or <a href=\"https:\/\/www.privateinternetaccess.com\/blog\/how-to-prevent-malware\/\">DDoS attack<\/a>), nobody can connect to the corporate network. That could stop all remote work and even affect office operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How to fix it:<\/strong> Don\u2019t rely on a single server. Set up backup VPN servers and use load balancing to spread users across them. That way, if one server fails or is overloaded, connections automatically switch to another and work can continue.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-outdated-vpn-software\">Outdated VPN Software<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If organizations don\u2019t regularly patch their VPN software or hardware, known vulnerabilities can be exploited by attackers.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How to fix it:<\/strong> Keep your VPN software and appliances updated with the latest security patches. Set a regular patching schedule, turn on automatic updates where possible, and monitor vendor security advisories so you can apply fixes quickly when new flaws are discovered.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-lack-of-visibility-into-vpn-traffic\">Lack of Visibility Into VPN Traffic<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The side effect of all traffic inside the VPN tunnel being encrypted is that IT departments can\u2019t see what\u2019s actually happening inside. If, for example, malware is exfiltrating data or an insider is moving files around they shouldn\u2019t, the usual network security tools can\u2019t flag it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How to fix it:<\/strong> Track behavior instead of content. Watch for unusual logins, like odd hours, or suspicious activity, like large data transfers. You could also deploy deep packet inspection (DPI) or TLS inspection at the VPN gateway, or log and analyze VPN session activity with a security information and event management (SIEM) solution.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rava\">Remote Access VPN Alternatives<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2400\" height=\"2154\" style=\"margin-bottom: 15px; margin-top: 15px;\" src=\"https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/5-remote-access-vpn-alternatives.png\" alt=\"5 blocks covering remote access VPN alternatives, including Zero trust network access (ZTNA), Secure access service edge (SASE), Virtual desktop infrastructure (VDI), Cloud access security broker (CASB), Application0level gateway (Proxy).\" class=\"wp-image-33037\" srcset=\"https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/5-remote-access-vpn-alternatives.png 2400w, https:\/\/www.privateinternetaccess.com\/blog\/wp-content\/uploads\/2025\/10\/5-remote-access-vpn-alternatives-300x269.png 300w\" sizes=\"auto, (max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 1362px) 62vw, 840px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">VPNs are a secure and reliable solution for remote access. However, as teams grow, environments become more complex, and use cases expand (like cloud services or BYOD), some situations may call for extra layers of access control or flexibility. In these cases, you may need additional tools to complement or extend the capabilities of a traditional VPN setup. Here are some examples:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"ztn\">Zero Trust Network Access (ZTNA)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">ZTNA works on the idea of \u201cnever trust, always verify.\u201d Instead of giving users full access to a network like VPNs do, ZTNA only lets them access the specific apps or resources they need. It checks who they are, where they\u2019re connecting from, how healthy their device is, and how they behave. This limits potential damage if something goes wrong because users can\u2019t roam freely inside the network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When you should consider it:\u00a0<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Granting third-party vendors access to specific internal apps<\/li>\n\n\n\n<li>Providing remote employees access to only necessary resources<\/li>\n\n\n\n<li>Reducing lateral movement risks within the network<\/li>\n\n\n\n<li>Enforcing stronger access controls based on user identity and device posture<\/li>\n\n\n\n<li>Supporting a Zero Trust security strategy over traditional VPN models<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-secure-access-service-edge-sase\">Secure Access Service Edge (SASE)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.privateinternetaccess.com\/blog\/what-is-sase\/\">SASE<\/a> is a cloud-based system with built-in security tools like ZTNA, firewalls, and secure web gateways. It helps you manage security from one place and gives better speed and protection, no matter where users connect from.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When you should consider it:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You need to secure access for remote or hybrid employees.<\/li>\n\n\n\n<li>You want to simplify security management by unifying multiple tools.<\/li>\n\n\n\n<li>You need to improve network performance with cloud-optimized routing.<\/li>\n\n\n\n<li>You must enforce strict access controls based on user identity and device health.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-virtual-desktop-infrastructure-vdi\">Virtual Desktop Infrastructure (VDI)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">VDI lets users work on a virtual computer that runs on a remote server, not on their own device. This means all data stays secure on the server, reducing risks like data theft or loss. It also makes managing software updates and following security rules easier because everything happens in a controlled environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When you should consider it:\u00a0<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You need to keep sensitive data off user devices.<\/li>\n\n\n\n<li>You need to provide secure, consistent desktop environments for remote or mobile users.<\/li>\n\n\n\n<li>You need to simplify software deployment and patch management.<\/li>\n\n\n\n<li>You need to enforce centralized control over user sessions and data access.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-cloud-access-security-broker-casb\">Cloud Access Security Broker (CASB)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CASBs act as a security guard between users and cloud apps like Microsoft 365 or Google Workspace. They keep an eye on who\u2019s using which apps, enforce rules about what can be accessed, and detect any suspicious activity. CASBs help companies protect sensitive data and follow privacy laws in cloud-based work setups.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When you should consider it:\u00a0<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You need to monitor and control access to cloud applications.<\/li>\n\n\n\n<li>You need to enforce data loss prevention (DLP) and compliance policies.<\/li>\n\n\n\n<li>You need to detect and respond to suspicious or risky user activity in cloud apps.<\/li>\n\n\n\n<li>You need to gain visibility and control over shadow IT usage.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-application-level-gateways-proxies\">Application-Level Gateways (Proxies)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These work like traffic controllers, directing users only to specific apps instead of the whole network. They usually have security features like login checks and threat detection. By only exposing certain applications, proxies reduce the chances of attacks and make it easier to keep an eye on activity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When you should consider it:\u00a0<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You need to restrict user access to select applications only.<\/li>\n\n\n\n<li>You need to implement additional security layers, like authentication and threat inspection.<\/li>\n\n\n\n<li>You need to monitor and log user activity for compliance and auditing.<\/li>\n\n\n\n<li>You need to minimize exposure of the internal network to external threats.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-faq\">FAQ<\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1761203033098\"><h3 class=\"schema-faq-question\">What is a remote access VPN, and how does it work?<\/h3> <p class=\"schema-faq-answer\">A <a href=\"#wia\">remote access VPN<\/a> allows you to securely connect to a private network over the internet.
