SDP vs. VPN: What is best for you?

VPNs have been used by remote employees for a while now, and they’ve worked just fine. They employed VPN technology to get access to information held on workplace servers. But things have changed.

As a result of the COVID-19, the number of remote workers has increased dramatically. Also, local storage of digital resources is not popular right now. This has created a demand for a different service than VPN. That’s where SPD came in.

What is SDP?

SDP stands for “software-defined perimeter.” As the name suggests, it is a software-based network boundary rather than a hardware-based one. What it does is conceal internet-connected infrastructure from outside parties and attackers, whether it is housed on-premises or in the cloud.

An SDP effectively hides a company’s servers and other infrastructure, preventing outsiders from seeing it; yet, authorized individuals can still use the infrastructure.

What is the relationship between SDP and ZTNA?

The ZTNA (Zero Trust Network Access) security solution offers secure remote access to applications and services. It doesn’t trust any user or device, and limits access to network resources, even if the user has previously accessed them.

By default, SDPs have a ZTNA design, which implies that access is denied unless a user can successfully authenticate their identity. ZTNA and SDP only provide users access to the resources they need, considerably reducing the danger of lateral movement that VPNs would otherwise enable.

What is a VPN?

VPN is the better-known one of the two. It is a secure network that runs over an open network. It establishes encrypted connections between devices and servers, making them appear to be connected to a private network.

VPNs have traditionally been used to protect and manage access to corporate infrastructure. An SDP can be used to substitute a VPN in some situations.

What are the differences between SDP and VPN?

There are many aspects SDPs and VPNs differ from each other. There are many resources online to learn more about SDP and VPN and their differences. But the most distinctive difference is that unlike VPNs, which let all connected users access the whole network, SDPs do not share network connections. SDPs can also be more manageable than VPNs, particularly if internet users need several levels of access. Due to these differences, VPNs are expected to lose popularity soon.

What is taking the place of VPNs?

ZTNA is regarded as the next generation of remote access solutions, as it addressed many of the security, administration, and user experience problems that surround VPN. According to Gartner, by 2023, 60% of businesses will have phased out the majority of their remote access VPNs in favor of ZTNA solutions such as SDP.

Which technology is the right fit for you?

SDP is a new technology that has the potential to improve cloud networking. This technology has given a comprehensive solution for reducing hardware dependency in the security setup. It has made network connection deployment, maintenance, and visualization much easier.


As a result, if you’re moving to the cloud, SDP may be the best security solution for you. It will allow you to create a customized network access policy for particular resources and workers.

If you don’t need access to advanced security capabilities, a VPN is a great choice. There are several VPN services on the market, so you should seek out the finest VPN option available.


In today’s online world, threats can originate from anywhere. To minimize risk and increase security, an SDP solution can go beyond encryption and credentialing. Finding a cybersecurity solution that fits your needs is essential, and it requires some research.

We advise you to thoroughly consider your needs and situation to find whether you need an SDP or VPN solution.
