What is remote access?
Remote access enables end users to access resources on a corporate network from afar. The most common function of remote access is to enable employees on business trips or working remotely to connect to the company network and access resources such as internal applications, intranets, mail services, and file sharing.

In the past, remote access was a service provided by companies through dial-up modems. To avoid the expense of long-distance or toll-free phone lines, companies are turning to remote access methods, using public networks over the Internet. Developments in Internet technology have led to the parallel growth of remote access, providing more adaptive and secure options.

How do companies provide remote access to employees?
The primary method of providing remote access is through a VPN connection. Often, users have no expectation of privacy on public networks because other users and system administrators can view their network traffic. A VPN creates a “tunnel” that privately passes traffic between a remote network and a user. Tunnels protect traffic and protect it from interception or tampering.

An emerging remote access model provides the benefits of tunneling for broad application support while maintaining strong control over application access through next-generation firewall security policies. This approach allows administrators to securely enable remote user activity and network access. Combining the advantages of earlier implementations, this model is the most secure and practical remote access solution available today.

What is a VPN?
Virtual private networks allow you to securely connect to another network on the Internet by encrypting connections from your personal devices. Essentially, it’s a way to connect to a corporate network without having to be physically located in an office or campus. It allows remote employees working outside the office to connect to the periphery of a typical corporate environment in a secure manner. VPNS allow remote workers to become extensions of the network as if they were in the office, with the same security and connectivity advantages. Think of it as a secure network line from users to applications, whether they reside in a private data center or on a public network.

VPNS make your Internet connection more secure and provide online privacy. Organizations, governments, and businesses of all sizes use VPNS to secure remote connections to the Internet against malicious actors, malware, and other cyber threats. Personal VPNS are also popular because they keep a user’s location secret, securely encrypt data and allow users to browse the Internet anonymously.

As remote workers rapidly become more common, businesses across industries are moving outside headquarters, but employees still need a secure way to access applications and data to get their work done.

There are two types of VPNS:

Site-to-site VPNS are used to connect branches to central offices over the Internet when distance prevents direct network connections.
Remote access VPNS allow individual users to connect remotely to a central network. In this case, these devices are called endpoints
Why is a secure VPN combined with remote labor technology the answer to the remote work challenge
The only way to protect remote workers is a secure VPN. Employees must connect from their laptops, desktops, and mobile devices via VPN connections. It’s a secure, private way to virtually enter a corporate office, so to speak.

In many cases, remote workforce technology requires hardware. At the moment, it’s hard to get hardware quickly because of shipping delays around the world. Fortunately, there are other ways to connect employees to the company network from home while ensuring their user experience is not compromised. People can use VPNS to work efficiently without delay.

How does VPN work?
As mentioned above, VPNS create dedicated connections called tunnels. All information transmitted from devices connected to the VPN will be encrypted and passed through this tunnel. When connected to a VPN, the device behaves as if it were on the same local network as the VPN. A VPN forwards device traffic to a target website or network over its secure connection. This allows your remote users and offices to securely connect to the corporate network or web site. It can also hide your IP address from hackers and prying eyes.

With A VPN, data travels over the Internet over a secure tunneling protocol, in which the data is encrypted to prevent any third party from reading your data while in transit. The two most popular suites of cryptographic network protocols are:

Secure Sockets Layer (SSL) or Nearest Transport Layer Security (TLS)
Internet Protocol Security (IPsec)
Essentially, encryption disrupts the scam tent of your message — making it unreadable — and can only be decrypted using a key. The tunnel protocol also encapsulates the data with the routing information of the receiving user. Once a remote access connection is received, it is bound by the authentication, authorization, and billing server program that authenticates, authorizes access, and accounts all online activities of the user during the connection.

What is remote access VPN?
Remote access Virtual private networks enable users working remotely to securely access and use applications and data residing in corporate data centers and headquarters, encrypting all traffic sent and received by users.

Remote access VPNS do this by creating a tunnel between an organization’s network and remote users who are “virtual private,” even though users might be using public WiFi hotspots in coffee shops.

It’s important to note that as applications move to the cloud, users don’t often need to connect to remotely access a VPN. Poor Internet connections and bandwidth can cause users to disconnect, as Internet traffic is diverted to data centers and then to the public. However, disconnecting users creates a security problem: the organization loses visibility and control over user traffic. To address this shortcoming, security teams often add point products, such as proxies, to handle traffic when a user disconnects from a VPN. This creates security issues, with different traffic paths following different security policies.

A more recent approach is to use secure Access service Edge (SASE; Pronounced “sassy”), which replaces the combination of VPN and a single point of product with a combination of networking and network security services delivered from the cloud. With SASE, organizations do not have to maintain separate independent proxies or VPNS. Instead, users connect to a SASE solution with consistent security that provides access to the cloud and data center.

What is a site-to-site VPN?
A site-to-site VPN is a connection between two or more networks, such as a corporate network and a branch office network.

Site-to-site VPNS are often used by companies with multiple offices in different geographical locations that need ongoing access to and use of corporate networks. With a site-to-site VPN, companies can securely connect their corporate networks to remote offices, communicating and sharing resources with them as a single network. Remote access to VPN. However, disconnecting users creates a security problem: the organization loses visibility and control over user traffic. To address this shortcoming, security teams often add point products, such as proxies, to handle traffic when a user disconnects from a VPN. This creates security issues, with different traffic paths following different security policies.

Site-to-site VPNS and remote access VPNS sound similar, but their purposes are completely different.

A site-to-site VPN is a permanent connection designed to serve as an encrypted link between offices (that is, “sites”). This is usually set to an IPsec network connection between network devices.
A remote access VPN is a temporary connection between a user and the headquarters, typically used to access data center applications. This connection can be made using IPsec, but it is also common to use SSL VPN to establish a connection between a user endpoint and a VPN gateway.
Companies have traditionally used site-to-site VPNS to connect their corporate networks to remote branches in a hub-and-spoke topology. This approach is suitable for companies with internal data centers, highly sensitive data and applications, or minimum bandwidth requirements. However, now that most companies have moved their applications and data to the cloud and have a large mobile workforce, it no longer makes sense for users to have to go through an internal data center to get there when they can. Go straight to the clouds.

Therefore, companies need to set up network topologies that can access cloud or data center applications. This encourages organizations to build network architectures that do not rely on bringing all traffic back to headquarters.

As mentioned above, SASE provides the networking and network security services required by companies directly through the cloud infrastructure. In addition, SASE provides multiple security features such as advanced threat protection, credential theft protection, Web filtering, sandbox, DNS security, data loss protection (DLP) and more through a cloud delivery platform.

This allows companies to easily connect their remote offices; Securely routing traffic to public or private clouds, software as a service (SaaS) applications, or the Internet; And manage and control access.
