What is ipsec?

How secure is SSL?

SSL gives users more specific access than IPsec. Rather than becoming a full member of the network, remote team members are granted access to particular applications. This makes it simple to provide different levels of access to different users. Security is maintained by restricting access to only what’s needed.
Like IPsec, SSL has two modes. In portal mode, users access the VPN through a page in their web browser (the portal). This mode can only be used for web-based programs. It’s ideal for email, chat, file sharing, and other browser-based applications. In tunnel mode, by contrast, users can access any applications on the network, including ones that are not web based. Browser-based applications are becoming the industry standard, but older, offline programs can only be accessed using tunnel mode.

What is the difference between IPsec and SSL VPNs?

Choosing between IPsec vs SSL is an important decision when implementing a client’s VPN. As you can see, each type has its own advantages and disadvantages. Security and convenience are two key factors to consider. Because IPsec requires third-party client software, it is more complicated and expensive to set up and maintain. However, this also makes it more secure. It’s tough for a hacker to penetrate an IPsec system without knowing which client it uses and the exact settings to get that client to work properly. SSL is already supported by the remote user’s browser, so it needs no extra software and is simpler to configure. This simplicity, however, comes at the cost of being more vulnerable to security threats.
Once a user is logged into the network, SSL takes the upper hand in security. SSL VPNs work by accessing specific applications whereas IPsec users are treated as full members of the network. It’s therefore easier to restrict user access with SSL. If one of your clients works with a freelance employee, for example, they can give that person limited access to the programs they need without letting them see sensitive or proprietary company data. Restricting access in IPsec is possible with network user permissions, but that adds an extra step to the process.
Beyond security concerns, it’s also crucial to think about what services VPN users will need to access. If they will only be using web-based applications like email and cloud storage, SSL may be the right choice. Remote users can quickly connect to the applications they use without being confused by the ones they don’t. This makes SSL ideal for clients and freelance employees. But if users require full access—such as central office team members who are traveling—IPsec is the way to go. IPsec VPNs give users the ability to do whatever they can normally do while sitting in the main office from wherever they are.
Don’t forget that even a user on an IPsec or SSL VPN with ironclad encryption is still vulnerable to other security threats. Email phishing or phone-based social engineering attacks can strike a secure system at any time. That’s why it’s essential your clients provide their employees with mandatory, regular, and up-to-date security training. Knowing not to click on a suspicious link in an email or reveal a password over the phone is the first line of defense for maintaining a secure environment.
These are only some of the factors to consider when thinking about SSL vs. IPsec VPNs. IPsec is a time-tested system, while SSL is growing increasingly common. Each protocol has its strengths and weaknesses. MSPs will need to decide which solution is right for each client’s individual needs.
