What Is SSTP?

SSTP (Secure Socket Tunneling Protocol) is a VPN protocol that was developed by Microsoft, and introduced by them with Windows Vista. Newer Windows versions have been offering native support for the SSTP VPN protocol since then.

The protocol is designed to secure online data and traffic, and is considered a much safer option for Windows users than PPTP or L2TP/IPSec.

How Does the SSTP Protocol Work?

SSTP works by establishing a secure connection between a VPN client and a VPN server. Basically, the protocol creates a secure “tunnel” between the client and the server, and all the data and traffic that passes through that tunnel is encrypted.

Like PPTP (Point-to-Point Tunneling Protocol), SSTP transports PPP (Point-to-Point Protocol) traffic, but – unlike PPTP – it does it through a SSL/TLS channel. Because of that, SSTP offers significantly more security than PPTP since SSL/TLS provides traffic integrity checking, secure key negotiation, and encryption.

Due to the use of SSL/TLS, SSTP servers must be authenticated when a connection is established. SSTP clients can be optionally authenticated too.

General Technical Details About the SSTP VPN Protocol

  • SSTP uses TCP port 443 – the same port used by HTTPS traffic.
  • SSTP is often compared to OpenVPN thanks to the high level of security it offers, and the fact that it can bypass NAT firewalls.
  • SSTP doesn’t generally support site-to-site VPN tunnels. Instead, it supports roaming since it uses SSL transmissions.
  • SSTP only supports user authentication. The protocol doesn’t support device or computer authentication.

What Is Secure Socket Tunneling Protocol Service?

The “Secure Socket Tunneling Protocol Service” is a feature that was introduced with Windows Vista, and is also present on Windows 7, Windows 8, and Windows 10. Basically, it’s a service that offers support for the SSTP VPN protocol, allowing it to connect to remote devices through VPN connections. If the service is disabled, you won’t be able to access remote servers using the SSTP protocol.

You might also see that the “Secure Socket Tunneling Protocol Service” is related to the “SstpSvc.dll” file. You should avoid messing with that file or deleting it since it provides the SSTP service functionality on the Windows platform.

How Secure Is the SSTP Protocol?

Generally, SSTP encryption is considered relatively safe to use when you’re browsing the web. Many people even compare its security to the one offered by OpenVPN – most likely because it uses SSL and encapsulates data packets over HTTPS. What’s more, it can also use the AES encryption cipher, making it even safer.

However, it should be mentioned that there are two issues with SSTP:

It’s Susceptible to the “TCP Meltdown” Problem

Without getting too technical, that’s an issue that might occur with the TCP connection that’s created within the VPN tunnel, and takes places over the TCP transmission protocol. Basically, a TCP connection (the VPN one) contained within a TCP connection can result in a conflict between the two connections, which culminates in connectivity issues.

On its own, the “TCP Meltdown” problem isn’t really a huge security flaw with SSTP, but if you need round-the-clock online security or VPN encryption during critical moments (like when you’re downloading torrents, for example), it can be an annoying issue.

SSTP Is Owned by Microsoft

Another problem some people have with the SSTP VPN protocol is the fact that it’s closed-source and solely owned by Microsoft. While there is no evidence to showcase that SSTP was intentionally weakened or even cracked, it’s no secret that Microsoft has closely collaborated with the NSA in the past – even going as far as offering them access to encrypted messages.

What’s more, Microsoft belong to the PRISM surveillance program, and was even the program’s first partner. If you’re not familiar with PRISM, it’s a surveillance program run by the NSA which offers them access to emails, documents, and other user data that’s stored by major companies. So, it’s not far-fetched to think that the SSTP protocol might (emphasis on “might”) have been compromised by the NSA during or after development.

Overall, how good the security of the SSTP VPN protocol is solely depends on how much you trust Microsoft.

SSTP VPN Speed – What Should You Know?

SSTP offers decent online speeds most of the time, though you might encounter some slowdowns if you don’t have enough bandwidth or a relatively strong CPU. Don’t forget – SSTP uses pretty strong encryption, and that can lower your online speeds, especially if a powerful encryption cipher is used too.

Also, you should consider the fact that there are plenty of other factors that can influence the online speeds you get when using an SSTP VPN connection.

SSTP Advantages and Disadvantages

Advantages

  • SSTP encryption offers a decent level of security, almost on par with OpenVPN (SSL 3.0 256-bit encryption).
  • SSTP is easy to configure on platforms it is built into.
  • The SSTP VPN protocol is very difficult to block because it uses TCP port 443 (the same one HTTPS uses).
  • SSTP offers good speeds if you have enough bandwidth.

Disadvantages

  • SSTP is closed-source and solely owned by Microsoft, a company that is well known to collaborate with the NSA.
  • The SSTP protocol is available on a limited number of platforms – Windows, Linux, Android, and routers.
  • SSTP connections could be dropped if the network admin spots the SSTP header (which is possible to do since the protocol doesn’t support authenticated web proxies).
  • Since SSTP only works on TCP, it is susceptible to the “TCP Meltdown” issue.

What Is an SSTP VPN?

An SSTP VPN is a service offered by a VPN provider that gives you access to a ready-to-go SSTP VPN connection. Normally, you just need to download and install a VPN client, connect to a VPN server, and you’re good to go

Ideally, you shouldn’t stick to a VPN provider that only offers you access to the SSTP VPN protocol. It’s best to pick a provider who can offer you variety when it comes to choosing the VPN protocol you want to use.

Looking for a Reliable SSTP VPN Provider?

SSTP Compared to Other VPN Protocols

Here’s an in-depth overview showcasing how good or bad the SSTP VPN protocol is compared to the other VPN protocols you can use:

SSTP vs. OpenVPN

Security-wise, both VPN protocols are decent options since they can use strong encryption keys and ciphers, and also use SSL 3.0. But unlike SSTP, OpenVPN is open-source and is not solely owned by Microsoft. That makes it easier for online users to trust that the protocol offers reliable security with no potential loopholes.

Besides that, OpenVPN can also use the UDP transmission protocol alongside the TCP one which is used by SSTP. As a result, you’re likely to get better online speeds with OpenVPN than with TCP. Also, OpenVPN isn’t susceptible to the “TCP Meltdown” issue mentioned above.

And while SSTP can’t really be blocked by firewalls easily since it uses port 443 just like OpenVPN (the HTTPS port), it does have one weakness – the fact that it doesn’t support authenticated web proxies. Why is that a problem? Well, if SSTP uses a non-authenticated web proxy, the administrator of a network could potentially detect SSTP headers. In that situation, they could drop the connection if they want to.

OpenVPN is also available on more platforms than SSTP. While it is convenient that SSTP is natively built into Windows operating systems, and thus can be easily set up, it can only be configured on routers, Android, and Linux. OpenVPN, on the other hand, can be set up on all those platforms, including many others (like Windows XP, macOS, iOS, FreeBSD, OpenBSD, Solaris, and NetBSD.

Oh, and OpenVPN could potentially be more stable than SSTP when it comes to network changes. That’s because OpenVPN has the “float” command, which could ensure OpenVPN connections don’t drop when you switch networks.

SSTP vs. IPSec

Both protocols offer a pretty good level of security, though you might have to be a bit more careful when configuring the IPSec protocol since it’s easier to mess up the protection it offers if it’s not configured properly. On the plus side, IPSec works on more platforms than SSTP, like macOS, Windows 2000, Solaris, FreeBSD, OpenBSD, and NetBSD.

Also, IPSec is much easier to block with a firewall than SSTP. Since SSTP uses TCP port 443 (the same port used by HTTPS), a network admin or ISP can’t really block it without also blocking all other online activities. IPSec traffic, on the other hand, can be blocked if the network admin or ISP blocks IP protocols 50 (which stops the Encapsulating Security Payload offered by IPSec) and 51 (which would stop the Authentication Header used by IPSec). The same can happen if port 500 is blocked since it’s the port used for IPSec’s Internet Security Association and Key Management Protocol (ISAKMP).

In terms of speed, there’s a chance that SSTP might be faster than IPSec because it can take IPSec longer to negotiate a VPN tunnel. A lot of online users have also been complaining, saying that IPSec tends to eat up a lot of resources – something that can further lower online speeds.

IPSec is normally paired with L2TP or IKEv2, but you might see VPN providers who offer IPSec as a protocol on its own. Overall, we’d recommend using SSTP over IPSec if possible.

In case you’d like to learn more about IPSec, follow this link.

SSTP vs. IKEv2/IPSec

If you’re mostly interested in security, you should know that both SSTP and IKEv2/IPSec offer a similar level of protection. IKEv2/IPSec might be a bit more trustworthy than SSTP, though, since it’s not solely owned by Microsoft. Instead, it was developed by Microsoft together with Cisco. Also, there are open-source implementations of IKEv2 available online.

In terms of cross-platform compatibility, IKEv2/IPSec has limited support just like SSTP, but it still has an advantage since it also works on iOS, macOS, and BlackBerry platforms.

As for speed and stability, IKEv2 might potentially be a bit faster than SSTP since it uses UDP, but it’s unfortunately also easier to block than SSTP because it only uses UDP port 500. If a network admin blocks it, IKEv2/IPSec traffic is blocked altogether. SSTP, however, uses TCP port 443, which is much harder to block. Still, IKEv2 has a very nice perk when it comes to stability – MOBIKE (IKEv2 Mobility and Multihoming), a feature that allows the protocol to seamlessly resist network changes without the connection being dropped.

In the end, IKEv2/IPSec is only a better option than SSTP if you use your mobile device a lot and travel often, or if you’d prefer an open-source alternative to SSTP that’s easy to set up on Windows platforms and BlackBerry devices.

SSTP vs. L2TP/IPSec

Generally, SSTP is a much more secure option than L2TP/IPSec, though it is worth mentioning that some online users have an easier time placing their trust in L2TP/IPSec because it’s not solely developed by Microsoft. However, L2TP/IPSec is easier blocked with a firewall than SSTP, making it overall less reliable.

In terms of connection speeds, L2TP/IPSec is inferior to SSTP because it uses double encapsulation – meaning it encrypts online traffic twice. There’s also a chance that L2TP/IPSec is more resource-intensive than SSTP.

On the other hand, L2TP/IPSec is available on more platforms than SSTP. What’s more, L2TP is even built into more devices and operating systems than SSTP, which is only built into Windows Vista and higher.

If you were to choose between SSTP and L2TP/IPSec, we’d say you’d be better off with SSTP.

In case you’re interested in learning more about L2TP, follow this link.

SSTP vs. PPTP

Both SSTP and PPTP have been developed by Microsoft, though PPTP was developed by Microsoft together with other companies. When it comes to security, SSTP surpasses PPTP because it offers better protection – especially since it has support for 256-bit encryption keys, while PPTP can only has support for 128-bit keys.

Normally, that wouldn’t be a huge issue for PPTP users, but the main problem is with PPTP’s own encryption – MPPE – which is very flawed. Also, it has been shown that the NSA can crack PPTP traffic.

The only way PPTP is better than SSTP is when it comes to speed and availability. Due to its poor encryption, PPTP offers very fast connections. Also, PPTP is natively built into many platforms, though it is worth mentioning that – due to the protocol’s poor security – it might not continue to be natively included in future operating systems and devices. For example, PPTP is no longer natively available on macOS Sierra and iOS 10 (and newer versions).

SSTP vs. SoftEther

SSTP and SoftEther both seem to offer a decent level of security when it comes to high encryption and supported ciphers, but SoftEther is simply more trustworthy because it’s open-source and because it isn’t owned by a company that’s been known to collaborate with the NSA. Also, SoftEther has a wide variety of security features that make it even stronger.

Speed-wise, there’s a chance that SoftEther is faster than SSTP since it was programmed with fast throughput in mind. Also, SoftEther is allegedly 13 times faster than OpenVPN, and SSTP speeds are often considered to be on a similar level to OpenVPN connection speeds.

Now, it’s true that SoftEther might be more difficult or inconvenient to set up than SSTP. After all, SSTP is natively built into Windows platforms, so it can easily be configured with a few clicks. What’s more, if you use a third-party VPN service that offers SoftEther connections, you’ll still need to download and install the SoftEther software on your device.

On the other hand, SoftEther works on more platforms than SSTP, which is only available natively on Windows operating systems, and can be manually configured on routers, Android, and Linux. SoftEther works on all those platforms, and on other operating systems and devices like iOS, FreeBSD, Solaris, and macOS.

Another difference worth mentioning is the fact that the SoftEther VPN server actually offers support for the SSTP VPN protocol – alongside many other VPN protocols like OpenVPN, L2TP/IPSec, IPSec, and SoftEther. An SSTP VPN server doesn’t offer such flexibility.

Overall, SoftEther is a much better option than SSTP – especially if you are looking for an open-source alternative.

If you’d like to learn more about the SoftEther protocol, follow this link.

SSTP vs. WireGuard ®

We believe both protocols can secure your data. But if you’re obsessed with privacy, stick with WireGuard. It’s open-source and not owned by Microsoft.

You shouldn’t experience random disconnects with either protocol. However, SSTP gets an extra point because network admins can’t easily block it. The protocol uses TCP port 443, which is the HTTPS port. WireGuard only uses UDP ports (a lot of them, though).

sstp, android, download, open

WireGuard is less resource-intensive than SSTP, so you’ll always get smoother speeds.

WireGuard actually works on more platforms since macOS and iOS don’t support SSTP out of the box.

If you want security, both protocols are decent options. But if you want security, guaranteed privacy, and speed, then stick to WireGuard.

Considering All That, Is the SSTP VPN Protocol a Good Choice?

Well, if you’re a Windows user and can’t use OpenVPN or SoftEther for various reasons, SSTP is the next best VPN protocol in terms of security and reliability. Of course, that depends on how much you trust the Microsoft corporation. If you’re not particularly worried about that aspect, though, SSTP could be a good choice then.

What Is SSTP? The Main Idea

SSTP is a VPN protocol that encrypts online communications between a VPN client and a VPN server. It’s generally considered as secure as OpenVPN, but many online users don’t trust it fully because it’s solely owned by Microsoft. Also, the protocol has limited cross-platform compatibility, only being natively available on Windows, and supporting configurations on Android, Linux, and routers.

Overall, SSTP is a good choice if you don’t mind the fact that it’s owned by Microsoft, and that it’s not open-source. We generally recommend using it only when OpenVPN or SoftEther are not valid options.

SSTP Connect Reviews

In my organization we use Microsoft VPN servers. End users connect using SSTP. This works great with Windows machines, but it leaves iOS devices out in the cold. In the past, I also supported L2TP as a second protocol just to use with our iOS devices. The problem is that we moved to multi factor authentication (MFA) for VPN using the Microsoft Authenticator app. This works great for our Windows machines, but it wouldn’t work with L2TP on iOS devices. I was looking for a solution to all of this, when I came across your app yesterday. Not only does it support SSTP perfectly, but it works with Microsoft Authenticator for MFA. Fantastic! Other great features include the ability to save multiple VPN profiles, great logging, on demand connection rules and automatic reconnection. It integrates beautifully into iOS. There are some useful security options for controlling TLS and MSCHAP versions and some handy controls for setting TCP/IP and DNS. Overall, I’m so glad I found this app. Well worth the cost.

If you are looking for an easy to use iOS VPN client for SoftEther VPN, this is it! Make sure to use port 443, and that your local DHCP server is running without Android address filtering. Use the SoftEther VPN Client Manager to create a.VPN configuration file and upload to your iCloud Drive so you can easily import into the app. Thank you University of Tsukuba students and thank you Domosekai Limited!

VPN over HTTPS is such a sneaky and cool concept, I love the privacy it provides, and softether is so easy to configure on the server side, now with this, it’s just perfect, and it appears more stable than L2TP client, especially when iOS doesn’t automatically reconnect you. This is essential for visiting China.

What is SSTP VPN and why should you know about it

What is SSTP VPN? How does it compare to other VPN protocols? Is it the best protocol available? Is it the safest? Should I use SSTP? Does it offer good speeds? These are all questions you’re probably asking yourself if you are trying to decide which VPN protocol to use.

What is the SSTP VPN protocol?

The Secure Socket Tunneling Protocol (STTP) is a tunneling protocol which is oftentimes used for Virtual Private Connections (VPN). It was originally launched by Microsoft on the Windows Vista operating system.

The protocol enables the establishment of a SSTP tunnel using the SSL/TLS protocol. As with most VPN protocols, a connection first needs to be established between the client device and the VPN server. This is done through TCP port 443. Upon establishing this connection, the handshake operation takes place.

SSTP technical details

Now that we have a relative idea about the answer to the question “ What is SSTP VPN? ”, let’s take a look at the processes behind it that make it work.

How does SSTP work?

SSTP was made as an improvement to the older point-to-point protocol which didn’t offer the SSL/TLS transmission option. SSL refers to the Secure Socket Layer Protocol, which is used for securely transmitting information over the network. SSTP allows users to access networks using HTTPS.

In order to better understand the protocol, let’s examine another protocol implemented into SSTP, namely, the SSL/TLS security protocol.

SSL/TLS

The SSL protocol has been upgraded to the transport layer security (TLS), and is applied through port 443 using the transmission control protocol (TCP). SSL/TLS does offer security features such as key negotiation, encryption. and can also check the data packets’ integrity.

The SSL protocol was last updated in 1996, while still under Netscape development. Afterward, ownership was changed and it was renamed TLS. Afterward, the protocol underwent further updates, the last one having been released in 2018. Strangely enough, this security protocol is still widely known as SSL. However, in many cases, although it is mentioned as SSL, actually the TLS protocol is used.

Hopefully, this is the case with SSTP as well. It is actually a little confusing because some sources state that the SSTP protocol uses SSL 3.0, whereas others claim it uses the SSL/TLS protocol.

SSL/TLS provides authentication through what is known as the handshake. Some protocols used for the authentication stage are EAP (extensible authentication protocol) and MS-CHAP (Microsoft’s own version of the challenge-handshake authentication protocol). Furthermore, SSL/TLS leaves a kind of “stamp” or sign on the information it sends in order to guarantee the integrity of the data.

During the SSL/TLS phase, the SSTP server has to be authenticated, whereas client authentication is optional at this point. However, client authentication is obligatory during the PPP phase.

SSTP speed, security, setup process and compatibility

Perhaps for some readers who are well-documented, or perhaps for IT specialists, the above section may have proved to be of great interest. For most of us, however, it’s probably rather difficult to process and understand. Therefore, let’s take a look at some of the more graspable information regarding more approachable aspects.

What browsing speed does SSTP offer?

Obviously, speed is one of the most important factors for VPN users, after security. For most users, if a VPN is frustratingly slow, they will often decide to opt for a different protocol.

The SSTP protocol seems to offer decent speeds for good computers with good connections. This means that you would need to have a good central processing unit (CPU), as well as a good bandwidth.

If you don’t check these requirements, you might find yourself confronted with frustrating internet speeds and laggy connections. This is in part due to the strong SSL/TLS encryption.

That being said, SSTP may not be the best option for low-specification devices if you are looking for a lightning-fast internet connection.

How secure is the SSTP protocol?

It seems that the SSTP may be among the more secure protocols. Boasting the AES 256-bit encryption offered by the TLS security protocol, in this aspect SSTP seems to come up to the security level offered by OpenVPN. perhaps the most appreciated VPN protocol available.

While the specifications are promising, the SSTP protocol does prove to be lacking in at least one aspect. Having been produced solely by Microsoft, it doesn’t have the open-source character available with other protocols. over, Microsoft has been known for not being especially careful with user information.

How compatible is the SSTP protocol across various operating systems?

As previously mentioned, the secure socket tunneling protocol was designed by Microsoft and launched for its Windows Vista operating system. It went on to be implemented on Windows 7, 8, and 10. Thus, it is generally built into the Windows operating devices. However, what about the other major OSs?

It seems that the SSTP VPN protocol can be made to work on other devices such as Linux and Mac. However, it is not available on all smartphone operating systems, particularly iOS. Obviously, this considerably limits the access to this protocol across various devices.

over, because it is solely designed by Microsoft, and is not an open-source application, it has a lower chance of being configured and implemented for these other operating systems.

In conclusion, the SSTP is one of the more incompatible protocols for users, especially those who don’t own a device that functions using a modern Windows operating system.

SSTP setup process

For devices that have this VPN protocol built into them, the setup process is relatively simple, and only requires a few arrangements in the network settings. For other devices, however, it might be more complicated. What’s more, it seems that some devices have no option or possibility of setting up this particular VPN protocol.

SSTP versus other VPN protocols

Ok, so we’ve now got a relatively good idea of what SSTP has to offer. But to get an even clearer picture of the pros and cons of this protocol, it would definitely be of help to compare this protocol to the other major VPN protocols available.

SSTP vs OpenVPN

Right from the start, let me say that there are a lot of positive aspects with regards to this protocol. SSTP uses the AES 256-bit encryption. But so does OpenVPN.

However, OpenVPN has a very big advantage with regards to security, namely that it is an open-sourced protocol. This basically means that if any programmer finds a new improvement which can be added to this protocol, it can be implemented. Thus, you could see things like this: OpenVPN has people working on it all the time, as opposed to the Microsoft-owned SSTP protocol.

Another major win for the OpenVPN protocol is its availability across devices, being available to most major operating systems such as Windows, Mac, Linux, iOS and Android. As previously stated, SSTP does suffer somewhat regarding its compatibility features.

It is possible that SSTP would be more convenient for Windows users, as it is readily available on their devices, however nowadays, if you have a VPN subscription, most of the respectable VPN providers should offer OpenVPN as an option.

Having said these things, it would be fair to conclude that OpenVPN is a clear winner between these two protocols.

SSTP vs IKEv2/IPSEC

Once again using AES 256-bit encryption, IKEv2 offers the same encryption standard as the SSTP protocol. However, a major difference would be that the security protocol used in the case of IKEv2 is IPSec, whereas SSTP uses SSL/TLS.

With regards to speed. IKEv2 is probably superior. This may be in part due to the fact that it sends the packets over a UDP port, instead of a TCP port, as is the case for SSTP.

What’s more, the IKEv2/IPSec protocol supports the MOBIKE feature, which basically ensures a continuous VPN connection even when changing networks on a device.

In terms of compatibility, it is not the strong point for either one of these two protocols. While IKEv2 does have open-source implementations, it seems to offer less support for devices using other operating systems than Windows and Blackberry.

SSTP vs L2TP/IPSec

In terms of speed, SSTP is a clear winner, since L2TP/IPSec is not the fastest protocol out there. Due to its double encapsulation process, the browsing speeds offered by the L2TP VPN protocol can sometimes leave much to be desired.

As previously mentioned, SSTP does require a good CPU and bandwidth, but is also the safer of the two.

Copatibility-wise, however, L2TP has the edge, since it does offer a much wider range, being easily accessible on operating systems such as Windows, Mac, Linux, iOS, and Android.

SSTP vs PPTP

While both were created by Microsoft, SSTP has a slight disadvantage of being developed solely by Microsoft. Despite that, SSTP is a better candidate in terms of security because it offers 256-bit encryption.

In terms of speed however, SSPT takes a back seat when compared to PPTP. The stronger encryption makes SSTP slower. When it comes to compatibility, PPTP comes on top once again because it is natively integrated into many platforms.

SSTP vs SoftEther

SSTP and SoftEther both seem to offer a decent level of security when it comes to high encryption and supported ciphers, but SoftEther is simply more trustworthy because it’s open-source and because it isn’t owned by a company that’s been known to collaborate with the NSA. Speed-wise, there’s a chance that SoftEther is faster than SSTP since it was programmed with fast throughput in mind.

While it’s true that SoftEther may be more difficult or inconvenient to configure than SSTP. After all, SSTP is built into the Windows platform, so it can be easily configured with just a few clicks. In addition, if you use a third-party VPN service that provides SoftEther connections, you still need to download and install SoftEther software on your device.

To sum up, SoftEther is the better alternative in this comparison for the obvious reasons. security and speed.

Conclusion

To sum things up, it would be fair to say that, while SSTP seems to be a fairly decent VPN protocol, having been produced solely by Microsoft, its security is not completely reassuring.

over, since it’s not available on iOS devices, it doesn’t excel in terms of compatibility either. There seem to be better options available for VPN protocols, such as OpenVPN.
