SSTP VPN: Pros and Cons

sstp vpn frm Sahrzad

There are several types of vpn available today. We have discussed different types of vpn recently and offered you some tips how to select the best vpn for your needs.

Today we would like to describe SSTP VPN, its main features, advantages and disadvantages.

Without a doubt, VPN (Virtual Private Network) is the best way to browse the web anonymously no matter where you are. Besides being affordable and offers fast Internet connection, VPN traffic is highly encrypted thus protecting you from unwanted third parties even if you are in Wi-Fi zone. There are many types of VPN, and SSTP VPN is only one of them.

By simple definition, SSTP (Secure Socket Tunneling Protocol) VPN is a proprietary Microsoft protocol and was introduced in Windows Vista Service Pack 1 and therefore best suited for computers and gadgets running on Windows operating system. This application-layer protocol employs a synchronous data flow between two programs in a back and forth process.

As the client is connected to the Internet, connectivity is being established via common ports such as TCP 443 or 80. As the SSL (Secure Sockets Layer) negotiation takes place, the client gets the server certificate and will be validated. The client will also send a HTTPS request, where S means Secure. This makes it better than most VPN types for Windows users.

During the PPP (Point-to-Point Protocol) negotiation at both ends, the client is being authenticated to the server. Once this PPP has been completed, an IP interface shall be established on both the client and the server, and both ends can already to send IP packets to each other. With all of these processes, SSTP VPN addresses many VPN connection problems.

Another great feature of SSTP VPN include having an integrated support for Network Access Protection (NAP). In addition, it establishes a single HTTP over SSL session from the client to the server, instead of two. Therefore, it offers better load balancing third-party SSL-based VPN solutions that use two HTTP over SSL session, thus providing lower network utilization.

Pros and Cons of SSTP VPN

Generally speaking, SSTP VPN is not only an application tunnel for one application and is virtually better against a very restrictive firewall as compared to other VPNs. Nevertheless, you should still understand its advantages and disadvantages so you know if it is compatible to your devices, and will satisfy your needs. Below are some of its major pros and cons:


➢ Best VPN for Windows users, when compared to OpenVPN and PPTP, and L2TP/IPsec
➢ Fully integrated into the VPN client components
➢ You are not required to install any third-party software, making it applicable independent
➢ Well-secured Internet connection, and can bypass most firewalls
➢ SSTP has stronger forced authentication than IPSec. and has support for non IP protocols
➢ SSTP can be configured to use AES encryption, making it more trustworthy than L2TP/IPsec


➢ Compatible only on Windows-based devices, since it is exclusively designed for Microsoft
➢ Being a proprietary protocol, it is not subject to the independent audits, as compared to OpenVPN
➢ Very poor or totally no support on non-Microsoft platforms, such as Apple
➢ Does not support site-to-site VPN tunnels, unlike the PPTP and L2TP/IPsec protocols
➢ Prone to the TCP meltdown problem, where performance depends on the sufficient excess bandwidth

Which VPN Protocol is the best? PPTP vs. OpenVPN vs. L2TP/IPsec vs. SSTP

vpn types

PPTP VPN Protocol

Point-to-point tunneling protocol is common and easy to set up. PPTP clients are built into many platforms, including Windows. It is said that this type of vpn protocol is not very secure.


SSL or OpenVPN

OpenVPN uses open-source technologies like the OpenSSL encryption library and SSL v3/TLS v1 protocols. It can be configured to run on any port, so you could configure a server to work over TCP port 443. The OpenSSL VPN traffic would then be practically indistinguishable from standard HTTPS traffic that occurs when you connect to a secure website. This makes it difficult to block completely.

It’s very configurable, and will be most secure if it’s set to use AES encryption instead of the weaker Blowfish encryption. OpenVPN has become a popular standard. We’ve seen no serious concerns that anyone (including the NSA) has compromised OpenVPN connections.

OpenVPN support isn’t integrated into popular desktop or mobile operating systems. Connecting to an OpenVPN network requires a a third-party application — either a desktop application or a mobile app. Yes, you can even use mobile apps to connect to OpenVPN networks on Apple’s iOS.

OpenVPN is new and secure, although you will need to install a third-party application.


Layer 2 Tunnel Protocol is a VPN protocol that doesn’t offer any encryption. That’s why it’s usually implemented along with IPsec encryption. As it’s built into modern desktop operating systems and mobile devices, it’s fairly easy to implement. But it uses UDP port 500 — that means it can’t be disguised on another port, like OpenVPN can. It’s thus much easier to block and harder to get around firewalls with.

IPsec encryption should be secure, theoretically. There are some concerns that the NSA could have weakened the standard, but no one knows for sure. Either way, this is a slower solution than OpenVPN. The traffic must be converted into L2TP form, and then encryption added on top with IPsec. It’s a two-step process.

L2TP/IPsec is theoretically secure, but there are some concerns. It’s easy to set up, but has trouble getting around firewalls and isn’t as efficient as OpenVPN.


Secure Socket Tunneling Protocol was introduced in Windows Vista Service Pack 1. It’s a proprietary Microsoft protocol, and is best supported on Windows. It may be more stable on Windows because it’s integrated into the operating system whereas OpenVPN isn’t — that’s the biggest potential advantage. Some support for it is available on other operating systems, but it’s nowhere near as widespread.

It can be configured to use very secure AES encryption, which is good. For Windows users, it’s certainly better than PPTP — but, as it’s a proprietary protocol, it isn’t subject to the independent audits OpenVPN is subject to. Because it uses SSL v3 like OpenVPN, it has similar abilities to bypass firewalls and should work better for this than L2TP/IPsec or PPTP.

It’s like OpenVPN, but mostly just for Windows and can’t be audited as fully.

Use Open vpn from Spider!


What do you know about your Internet privacy?


Do you think you are private on-line? You will be surprised but today really big money are made in violating your privacy. Companies will pay big bucks to learn more about you, and service providers on the web are eager to get their hands on as much information about you as possible.

So what do you do? How do you keep your information out of everyone else’s hands? Here’s a guide to surfing the Interneet while keeping your privacy intact.

The adage goes,

“If you’re not paying for a service, you’re the product, not the customer,”

and it’s never been more true.

Every day more news breaks about a new company that uploads your address book to their servers, skirts in-browser privacy protection, and tracks your every move on the web to learn as much about your browsing habits and activities as possible. In this post, we’ll explain why you should care, and help you lock down your surfing so you can browse in peace.

Why You Should Care


Your personal information is valuable. More valuable than you might think. Huge companies are ready to pay big money for information about people, their demographics, income, and habits, and then roll it up so they could get a complete picture about who you are and how to convince you to buy their products.

The real money is in taking your data and shacking up with third parties to help them come up with new ways to convince you to spend money, sign up for services, and give up more information. Relevant ads are nice, but the real value in your data exists where you won’t see it until you’re too tempted by the offer to know where it came from, whether it’s a coupon in your mailbox or a new daily deal site with incredible bargains tailored to your desires. It all sounds good until you realize the only thing you have to trade for such “exciting” bargains is everything personal about you: your age, income, families ages and income, medical history, dietary habits, favorite web sites, your birthday…the list goes on. It would be fine if you decided to give up this information for a tangible benefit, but you may never see a benefit aside from an ad, and no one’s including you in the decision.

So you must be very careful in the modern global network.

  1. Never share your personal information
  2. Stay protected in public wi-fi networks
  3. Do not save passwords
  4. Use privacy protection tools like VPN

Stay secure and private with pider VPN!
