Understanding VPN Encryption

VPN encryption creates a secure line of communication between 2 or more connected devices. As each device transmits data, the VPN scrambles all the information into an unreadable format and assigns an authentication key to protect the transmission. Only the VPN host can decrypt it and relay it to the end user (recipient). You can safely browse the internet (also on public WiFi) and do your online banking, thanks to a VPN. Hackers can’t read your data even if they intercept the communication because it’s chopped into random characters and cryptographically secured with private keys. So your sensitive information is well protected from snoops. IPsec and SSL VPNs encrypt and tunnel data differently. The most significant differences include:

The level and complexity of encryption Key authentication and exchange mechanisms Speed performance OSI layers where key exchange and data transfer happen The type of supported protocols and ports Ease of use

IPsec and How It Works

IPsec (Internet Protocol Security) provides advanced data protection, and is often used by businesses as well as consumers. It achieves this by encrypting IP packets sent over public IPv4/IPv6-based networks and verifying if the information source is secure. Sometimes, the encryption and verification process uses two-factor authentication (2FA) to enhance security, which requires a one-time code to log in. There are 2 modes of securing data — transport and tunnel. The first one encrypts only the payload of an IP packet, while the second mode encrypts the entire packet (new IP header). As such, IPsec offers high data confidentiality and integrity between the sender and receiver. It also supports network-level peer authentication, data origin authentication, and replay protection. Both users must install an IPsec client software (usually the VPN provider app) to make it work, which has to be regularly updated. For example, IPsec can be used between 2 routers to create a site-to-site VPN. VPNs deploy IPsec-based protocols like IKEv2, L2TP/IPsec, and SSTP for secure traffic tunneling. They were introduced in the mid-1990s as a part of the TCP/IP suite (​​maintained by the Internet Engineering Task Force) when more remote users needed easy access to the networks. SSL solutions came later, in 1999.

SSL and How It Works

SSL (Secure Sockets Layer) is a type of encryption used to protect communications between servers and web browsers or between email clients and email servers. On the consumer side, ExpressVPN’s WolfSSL is a great example of this, providing a lightweight solution to maintain speeds. Browser-based protocols provide safe end-to-end tunneling whenever remote users access web applications and client-server apps. For example, when you want to access an online payment website on your browser. The most popular protocol that uses SSL encryption is OpenVPN (OpenSSL library). It supports both UDP and TCP. Pre-installed client software isn’t required for SSL authentications, but the connected device should support browsers. This makes the SSL VPNs compatible with most phones, computers, and Smart TV devices. All major web browsers (such as Chrome, Firefox, and Safari) come with SSL support. The browser must perform a successful TLS handshake with an SSL gateway server to initiate a communication channel. TLS stands for Transport Layer Security and is the alternative modern name for SSL (the industry-standard SSL’s successor protocol since 2015), which has so far undergone many improvements. Contrary to IPsec, TLS is incorporated by default in web browsers and many other applications. There are 2 different types of SSL VPNs. The first one is SSL Portal VPN which connects users to specific sites and acts as a portal to other web-based programs, like email or file-sharing apps. SSL Tunnel VPNs allow access to multiple sites (also the ones that aren’t web-based) through 1 port. Bear in mind that whenever you connect to SSL VPNs through your browser instead of through a dedicated app, your non-browser internet activity isn’t protected by the VPN. In the wake of cloud-based networks and software, SSL is growing even more popular. This is because it’s the most convenient and faster for web communications. The software is automatically upgraded on the server and doesn’t require user interaction. Get a VPN for Safe Browsing Now

IPsec vs. SSL VPN — Differences in Performance

There are a few differences between IPsec and SSL VPNs. Let’s look closely at how these 2 perform and what their pros and cons are.

Security

While both IPsec and SSL VPNs provide secure encryption, the structural differences determine how a hacker can potentially gain access to your data. You can get maximum online protection using ExpressVPN, which offers high-end authentication with all its protocols. Here is how the IPsec and SSL VPNs compare to each other.

Authentication layers

The first key difference between IPsec and SSL is the layer where encryption and authentication happen. Based on the OSI (Open Systems Interconnection) model, computers communicate at 7 layers, namely: IPsec encrypts and authenticates internet traffic at the network layer and identifies communicating parties via their IP addresses. SSL operates at the transport layer and doesn’t inspect IP packets. The IPsec encryption is more resistant to DoS attacks than SSL/TLS because it operates at the lower network layer. Most of IPsec’s crucial security functions (like key generation) are done in the computer OS kernel, reducing cyber threat possibilities. TLS may be easier to attack because encryption happens at the higher network layer. Also, the public cryptography used by OpenSSL/TLS systems makes them vulnerable to the Heartbleed bug that can even bypass multi-factor authentication. Plus, SSL VPNs transport multiple circuits simultaneously — a separate circuit for each connection (contradictory to IPsec’s ​​single tunnel circuit for all network interactions). A hacker can monitor the individual SSL circuits and get bits of data about apps or services the user is accessing. It makes this protocol more vulnerable to worm and Trojan attacks.

Key Exchange vulnerabilities

In IPsec connections, the client and server must generate a shared key (using a built-in authentication) before data transfer allowing secure verifications. However, if attackers gain access to the pre-shared key, they can eavesdrop on the information. Top VPNs take care of this problem using AES 256-bit encryption, which is virtually uncrackable and provides anti-replay protection. SSL connections use public key cryptography (third-party integrations), so it’s more difficult for attackers to find the keys. But, some VPNs don’t have secure client verification mechanisms and may even permit untrustworthy self-signed certificates. Also, SSL uses the lower DES 128-bit cipher key encryption by default. Hackers may exploit these vulnerabilities and carry out man-in-the-middle (MITM) attacks on SSL VPNs. That’s why most SSL services integrate AES 256-bit encryption, besides 128-bit, to increase security. All in all, IPsec has a slight edge over SSL on the security front. Web-based applications are generally more vulnerable to malware attacks. They require frequent updating and patching so hackers can easily exploit it. Get A Secure IPsec and SSL VPN Today

Bypassing Firewalls

Public network firewalls block threats by filtering out data packets traveling without port numbers. This is a significant advantage for SSL VPNs because they use port 443 — a safe HTTPS port recognized on most devices. Routers and hardware that use the NAT firewall can easily allow SSL traffic. IPsec VPNs don’t transport encrypted ESP packets with assigned port numbers. Firewalls can quickly flag down and block them. To curb this challenge, such VPNs encapsulate the ESP packets inside UDP packets so they can be identified with a UDP port number. The commonly used UDP port number is 4500, but it may not be recognized on most private networks. In short, an SSL VPN is better for bypassing firewalls and geoblocks. However, most VPNs nowadays offer obfuscated servers that hide your traffic from detection. Others provide optimized servers for bypassing geoblocks on various content platforms, regardless of the protocol you use. So, an IPsec VPN might be as effective as an SSL one.

Speed

When comparing which protocol is faster (IPsec vs. SSL), it’s essential to consider how each connects end-users. IPsec protocols securely connect users to IP-based applications and remote networks or resources, such as printers and centralized storage. On the other hand, SSL protocols are designed to offer safe connections to web-based applications and services. IPsec VPNs might have better speeds for VoIP communications, streaming, or when accessing remotely connected devices, like printers and storage disks. SSL VPNs are generally faster at negotiating server or web connections — for example, it takes a shorter time to log in to an online portal. Although, the IKEv2/IPsec protocol also has a reputation for negotiating connections faster, for example, switching from phone data to WiFi. In conclusion, both are fast, but IPsec has a fair advantage over SSL VPN because it delivers good speeds on both online and remote connections. The IKEv2/IPsec protocol can be relatively faster than SSL protocols. However, consider that a VPN’s performance may be affected by many other factors, including server size, distance, and hardware quality. When I did online speed tests, there wasn’t any significant difference between the IPsec and SSL protocols. Try a Multi-Protocol ExpressVPN Risk-Free

Ease of Use

SSL VPNs only require a web browser connection and don’t need additional software configurations. Most internet-enabled devices already have client software for connecting to an SSL VPN. On the other hand, IPsec VPN users must install client software or apps to initiate end-to-end communications via a shared security key. Special hardware may be required in large network operations. It can be costly to set up and administer the software through regular updates. All in all, an SSL VPN is much easier to deploy and more low-maintenance than IPsec. However, as users can effortlessly log in from so many devices, there’s more space for various threats like viruses. The question of when it’s appropriate to use IPsec vs. SSL VPN depends on what you want to use the VPN for. IPsec might have shortcomings where SSL works better, and vice versa — each has pros and cons.

Is SSL better than IPsec?

Each encryption has its pros and cons. SSL can do better with web-based platforms, and IPsec is recommended when connecting to remote networks. So, the best VPNs provide both SSL and IPsec protocols to meet your different needs. To choose the better VPN for yourself, check which one offers faster speeds or more secure connections.

Is IPsec faster than SSL?

Whether you use an IPsec or SSL protocol doesn’t make a huge difference. Both can be fast, depending on what you use them for. IPsec may perform better in VoIP communications, but SSL is known to negotiate connections much faster. Top VPNs offer you IPsec and SSL protocol options, so you can pick either of them. Your VPN’s performance may also be affected by several other things, like server congestion and unstable connections.

Can SSL VPNs hide my IP address?

Yes, SSL VPNs use encryption and leak protection to conceal your actual location. However, only the best VPNs offer reliable IP security features. Premium services like ExpressVPN provide high standards of online privacy. You can try such VPNs with confidence because they’re backed by trustworthy money-back guarantees.

What are the pros and cons of IPsec and SSL?

IPsec has many protection layers, while SSL offers an easy way to connect to web apps. Both VPN protocols have high compatibility, though SSL is simpler because it doesn’t need many configurations. A VPN with multiple tunneling protocols balances the pros and cons. If you’re deploying a VPN for use in an organization, it might cost more to use IPsec due to the extra software required and maintenance expenses. SSL is much easier to implement but doesn’t offer extra safety features. Unlike IPsec, which has a built-in authentication (with 2FA), SSL depends on public third-party integrations, which can be compromised. However, SSL might be better at bypassing firewalls, especially on router devices. IPSec-based VPN protocols lack the open source code, which might be an issue for some users. According to Edward Snowden’s allegations, the NSA targeted IPsec with vulnerabilities that spies and hackers can exploit. However, VPNs come with other security and privacy features to keep your sensitive data hidden from snoops.

When should I use IPsec vs. SSL?

SSL VPN is recommended for web-based applications and IPsec for transmitting sensitive data. For example, SSL would be appropriate for email communications and IPsec when using a mobile payment app. Either way, the best VPNs cover up the flaws of IPsec and SSL protocols, so you won’t notice significant differences. You can safely use public WiFi or stream with no buffering. When choosing between IPsec vs. SSL, you should consider factors like user or business needs, security requirements, and the available infrastructure and resources. Many remote workers and employers need a VPN to access a company’s network. It can be set up by a managed service provider (MSP). However, nowadays, many companies have both on-premise and cloud software that require the use of both types of VPNs. IPsec runs better with traditional on-prem applications, while SSL is recommended for SaaS (Software as a Service) cloud-based apps. It’s also easier to restrict user access (for example, to the company’s data) with SSL if necessary. That’s because SSL VPNs work by accessing specific applications, not the entire network. Access control ensures only the right people can see sensitive information. So it’s great for clients and freelance employees. IPsec is a better option for remote office team members who need full access to company resources. Try ExpressVPN Risk-Free Now
