Best SSTP VPN Services & Reasons to Use in USA [Updated 2026]

Secure Socket Tunneling Protocol, or SSTP VPN, is a type of VPN that establishes a secure connection by transmitting PPP packets through an SSL 3.0 channel. Microsoft developed this protocol, which became popular with the advent of Windows Vista and Windows Server 2008.

To use it, you need at least Windows Vista, but it’s not exclusively for Windows users; with some adjustments, SSTP can be utilized on various platforms. Although SSTP is closely linked with Microsoft, it also works on Linux and routers. Information for setting it up on different operating systems is widely available, making it a versatile choice for many users.

This guide explains all about SSTP VPNs and how to set up a VPN based on the SSTP protocol on any device or operating system. I will also discuss the best VPN services with SSTP protocols.

What is SSTP VPN?

SSTP is a protocol technology through which PPP or packets can be sent over an SSL channel – more specifically, over SSL 3.0. PPP packet encapsulation through the SSTP protocol uses HTTP for data encapsulation purposes. SSTP saw the limelight with Windows 2008 and Windows Vista.

That is why you must have at least Windows Vista (or higher) installed to run SSTP. SSTP is much more secure than Microsoft’s pioneering.

The fact that Microsoft invented SSTP means that you might run into a bit of trouble finding it for other platforms. However, the tweaks and techniques needed to run SSTP on different platforms are now easy to find online in USA.

Adapting modern VPN solutions might seem challenging for users running older versions of Windows, such as the once-popular Windows XP.

When considering using the SSTP protocol for my VPN needs, I weigh both the advantages and disadvantages. On the plus side, SSTP VPN server connections utilize well-known and trusted ciphers, ensuring a solid security foundation.

The ease of setup is another benefit, as the integration with Windows makes it a hassle-free option for users of that operating system. Furthermore, using TCP over port 443 is a strategic choice, making SSTP difficult to block and great for bypassing firewalls.

However, I must also be mindful of the downsides. The SSTP protocol is proprietary to Microsoft, which means it lacks the transparency of open-source alternatives like SoftEther VPN and OpenVPN. Its compatibility is mainly with Windows platforms, limiting its utility across different devices and operating systems.

Additionally, there are potential speed issues due to TCP’s overhead and the risk of TCP meltdown in high-latency networks. It’s also worth noting that while SSTP is free to use on Windows, those wanting to buy SSTP VPN access through a provider will need to consider the cost involved.

How does SSTP VPN Function?

Delving into how SSTP functions, I find that the protocol operates by establishing a secure connection over port 443, which is commonly used for HTTPS traffic. This similarity to HTTPS is strategic, making SSTP traffic challenging to detect and block.

The use of SSL encryption means that the SSTP VPN server and client engage in a handshake process, verifying each other’s authenticity before any data transfer occurs. This process is crucial for maintaining the integrity and security of the data.

The SSTP protocol encapsulates Point-to-Point Protocol (PPP) traffic through an SSL channel, leveraging the strong authentication methods that PPP supports. This dual layer of security, combining PPP and SSL, is what gives SSTP its reputation for being secure in USA.

However, it’s important to remember that because SSTP uses SSL VPN, it can only run on TCP, which may lead to slower speeds than UDP protocols, such as OpenVPN.

Understanding other protocols like L2TP VPN can also broaden your knowledge of the various methods used for secure and encrypted connections, ensuring that your online activities remain private and protected against unauthorized access.

Pros and Cons of SSTP VPN

Here is the list of different benefits along with some cons of SSTP VPN that include:

Pros

SSTP offers next-level firewalls bypassing feature

It is considered one of the most secure protocols

Cons

Users may face speed issues at times
Compatible with Windows platform only

Reputation for Reliability and Security: Prioritize providers with strong encryption standards and a proven track record of protecting user privacy.
Range of Server Locations: Consider the variety of server locations available to ensure good speed and the ability to bypass geo-restrictions.
Cost: Wondering is it worth paying for a VPN? Compare prices and features of SSTP VPN services, noting that free options may not offer the same level of service as paid versions.
Ease of Setup: Look for providers that offer an SSTP VPN download to simplify the setup process, which is helpful for less tech-savvy users.
Customer Support: Choose a provider with responsive and knowledgeable support for troubleshooting complex protocol issues like SSTP.

How Can I set up SSTP VPN in USA?

What are SSTP Ports in USA?

A port number is really the name of a specific gateway. You probably know that any communication that takes place between two computer systems is essentially taking place between two IP addresses.

The port is like the gateway on top of which your IP address is painted in big lettering. It is the data sending/receiving point (not physically, of course, because it is a software construct) for which all data transmissions are destined.

Different data transmissions take place over different ports. However, for a data sending/receiving session to be complete, the names of the ports at both end-points need to be the same. For instance, Port 1234 won’t accept data sent by Port 567; it will only be processed by Port 1234.

SSTP uses port 443 (the same as HTTPS), making it easy for SSTP to get through your firewall. This might not sound like much to people who aren’t familiar with ports, but people who have a bit of experience with VPNs and/or ports will tell you that publicly accessible internet services usually block port 1723 to prevent outbound traffic.

In comparison, port 443 is one of the few commonly used ports and is, therefore, usually left unblocked. You probably do not know this, but if you have ever purchased over the internet, your Credit Card data was secured using HTTP over SSL through port 443.

Understanding the differences between VPN protocols, such as PPTP vs L2TP and PPTP vs OpenVPN, can also greatly enhance your online security and privacy by choosing the right one for your needs.

Authentication

The PPTP protocol does not use any certificates and carries out authentication before data traffic encryption begins for a VPN connection.

In comparison, L2TP/IPSec carries out encryption after the IPSec session has been established – with certificates on the VPN client as well as the VPN server side.

Similarly, SSTP uses the VPN server certificate and the VPN client’s root certificate to authenticate users after establishing the SSL session.

FAQs – SSTP VPN in USA

Can SSTP Be Used on Operating Systems Other Than Windows in USA?

While Microsoft developed SSTP and is natively supported on Windows, it can also be used on Linux and certain routers with additional configuration. For Android, an SSTP client may be necessary. It is not as widely supported as other VPN protocols like OpenVPN.

Is SSTP Vulnerable to Certain Types of Network Issues in USA?

SSTP can be affected by the so-called TCP meltdown,” which occurs when TCP traffic is heavily retransmitted due to packet loss or out-of-order delivery over spotty networks. While this can slow down SSTP connections, it remains a secure choice for users prioritizing security over speed.

Is SSTP a Good Choice for Bypassing Firewalls in USA?

Yes, SSTP is an excellent choice for bypassing firewalls since it uses TCP port 443, which is the same port used for secure HTTPS web traffic. This allows SSTP to blend in with regular internet traffic, making it difficult for firewalls to distinguish and block.

Wrapping Up

I’ve examined the Secure Socket Tunneling Protocol or SSTP VPN as a robust option for those prioritizing online security and privacy in USA. While its compatibility with Windows is a strong suit, it’s crucial to acknowledge that the protocol’s performance on other platforms can vary.

I recommend ExpressVPN for its consistent performance and security features. However, I’ve noticed from my competitor that there are some concerns with SSTP, like its susceptibility to TCP meltdown on unstable networks and its limited support across various platforms.

To address these concerns, it’s important to weigh the trade-offs of using SSTP against other protocols and to choose a VPN provider that supports a range of secure options.
