VPN Alternatives: What is the Best Solution for Remote Work?


VPNs (virtual private networks) are designed to enhance the reach of data networks beyond a physical limit. The vast availability and low cost of Internet services inspired businesses to take advantage of it and connect their branches, suppliers, and customers in a single network.

Traditionally, VPNs have been utilized as a secure remote access solution, allowing remote users to connect and authenticate with a VPN gateway to access the protected network. However, the biggest problem with implementing remote VPN access is security. Many security risks increase when you add more VPN-type accesses in a conventional network-centric model.

However, VPNs are now a thing of the past as there are many other alternatives for remote work and connectivity. Using a VPN alternative can enable a business to enhance the security and visibility of their WAN (wide area network). Here are some popular VPN alternatives that businesses can use for remote work.


Zero Trust Network Access

As a great VPN alternative, ZNTA (Zero Trust Network Access) is a brokered access to data and applications on a network, emphasizing data access control as a fundamental aspect of its security strategy. All users’ devices are verified before granting access.

The zero-trust methods are used to perform the primary capabilities of a VPN, like a grant of access to specific networks and systems, but with an additional layer of security in the form of identity authentication, credential storage, and employment verification.

As a result, if an attacker infects a system, the damage is restricted to the resources that this system has access to. Also, use network monitoring tools to detect unusual behavior, such as an infected machine performing a port scan, so you can produce an alert and shut down the infected machine automatically.


Limitations of ZNTA

More devices to manage: There are more devices to keep track of. In today’s workplace, there are not only many types of users but also various types of equipment for each of them. Different types of gadgets may have unique attributes and communication methods that must be monitored and secured.

Complex application management: Application management has become more difficult. Similarly, the applications are diverse. Apps are frequently cloud-based and can be used on various platforms. They may be shared with others. App use should be planned, monitored, and tailored especially to user needs, in keeping with a zero-trust attitude.


Secure Access Service Edge (SASE)

It is possible to verify every user and device using the ZNTA model before granting access at the network and application levels. However, it fixes only a part of the problem and does not monitor all the traffic from one endpoint to another.

SASE is a cloud-based approach that unifies network and security activities into a single architecture service, allowing a firm to manage its network from a single screen. With added layers of network functionality and underlying cloud-native security architecture, SASE is a modern solution built to satisfy today’s enterprises’ performance and security needs.

It enables simplified management and operation, lower costs, and better visibility and security. SASE enables IT teams and an organization’s complete workforce to work securely in the new normal of working from anywhere.


Limitations of SASE

The most important potential disadvantage is that IT teams forego some of the benefits of multisourcing, such as ensuring that various pieces are sourced from the best available providers for certain functions and reducing vendor risk.

Because SASE delivers all networking and security operations as a single service, consumers risk enormous single point of failure (SPOF) or exposure. Technical failures on the provider side can potentially result in full system shutdowns for end users.


Software-defined perimeter

A software-defined perimeter (SDP) is a network boundary based on software rather than hardware that is an effective alternative to traditional VPN solutions when used as part of larger zero-trust strategies.

Not only can you utilize multi-factor authentication and partition your network, but you can also profile the user and the device connecting and define rules to limit access to only what it truly requires in certain scenarios. SDP significantly enhances the ability to manage access securely, replacing VPN gateways with direct tunnels that offer improved security, performance, and user experience through granular access control.

Instead of completely disabling the device and rendering a user unable to do meaningful work, SDP blocks access to resources once it detects suspicious behavior in your network.


Limitations of SDP

Vulnerability of the controller: Controllers connect devices to secure resources, which is a crucial element in an SDP design. A link to resources cannot be made when controls are unavailable.

Device limitations: Despite the inclusion of many modern devices, it may be difficult to link old routers or vendor-specific devices with the SDP software.


Software-defined WAN (SD-WAN)

SD-WAN is intended to be a more efficient VPN alternative, especially for the corporate network. It delivers optimum routing of encrypted traffic between a network of SD-WAN appliances, addressing the needs of corporate networks by enhancing cost, performance, and reliability compared to traditional VPN solutions. In addition, secure SD-WAN solutions incorporate a whole security stack into an SD-WAN appliance to provide the necessary security for the corporate network.

SD-WAN’s key drawback is that it can only provide secure, optimal connectivity to locations where an SD-WAN device is installed. SASE solves this challenge by delivering cloud-based security services. Security services can be provided close to cloud-based resources or geographically dispersed remote employees, reducing the network performance impact of traffic routing over the SASE network.


IAM (Identity and Access Management)

Remote VPN access can benefit from enhanced security provided by an Identity and Access Management (IAM) infrastructure.

Instead of only requiring a username and password, identity management software integrates a thorough (and required!) verification process to ensure that all login attempts are authentic, while also establishing an encrypted connection to secure data transmissions between users and services.

(If you need a reason why this is important, read about the Colonial Pipeline attack, which occurred due to a lack of authentication.) You can use this solution to add multi-factor authentication to your remote VPN access connection. You can also assign authority to a third-party vendor using their IAM solution.

Another security aspect is that session activity and access privileges are tied to the specific user, allowing network administrators to ensure that each user has been granted access and trace each network connection. Additional layers of access are frequently provided by IAM systems, ensuring that users can only access the resources that they are allowed to use.

While this VPN alternative (or a solution to use in conjunction with your VPN) controls identification protocols and allows for more detailed activity monitoring, it does not provide additional security for privileged credentials. Therefore, a distinct approach is required to securely manage the credentials for privileged accounts.


Limitations of IAM

There is the risk of outsourcing critical functions, which is easily avoidable. When you transmit your identity management requirements to the cloud, your company’s firewall and crucial business functions are exposed to the internet.

If you’re planning to use an IDaaS solution, be sure your data and infrastructure are secure.


Use a third-party security platform.

When a company hires vendors, partners, or IT consultants, they need secure remote network access to support its technology and applications; hence, privileged access is frequently required.

Internal access accounts, which frequently have more limited control, require a different remote access method and more advanced security than external access accounts, which require a different remote access approach and more advanced protection.

Furthermore, third parties may have many support representatives who come and go from the organization. As a result, managing all of the moving pieces when deciding whether external entities should or shouldn’t have access to your network and secret information becomes difficult to manage using an IAM or PAM solution

Businesses can use a third-party remote access security solution to mitigate these dangers. For example, controlled on-boarding, and access termination privileges for external users can be accomplished with the help of a third-party security platform.

In addition, new proposed regulations governing remote access necessitate the inclusion of specific functionalities to remain compliant. These principles are included in third-party remote access systems to provide powerful authentication procedures, access controls, and auditing tools while assuring compliance.


5 Best VPN Alternatives

Here are some alternative tools that can be used as an alternative to traditional network solutions like virtual private networks (VPNs), which have historically linked remote offices to corporate data centers via the internet.
