Comparison Between IPsec VPN Versus SSL VPN
VPNs (Virtual Private Networks) on the Internet are typically available in IPsec (Internet Protocol Security), and SSL (Secure Sockets Layer). They both have pros and con. Learn everything you can about IPsec virtual private networks.
IPsec is defined as "a framework that consists of a collection of protocols to provide network security or at least packet protection." Security can be managed at the level of the network rather than individual computers.
IPsec is transparent with applications. Vpnveteran IPsec doesn't care how applications are transported because it is running on the Internet layer. This means that IPsec has little effect on what is happening on any other layers. IPsec VPNs have proven to be a great choice both for traditional traffic and real-time.
IPsec relies less on security certificates than SSL. SSL VPNs offer remote workers limited access to corporate resources, while IPsec VPNs provide a way for them to connect securely to the entire network.
IPsec does, however, pose a serious concern for malware spreading, as it connects the entire network of devices. When a remote employee connects their home network with the IPsec VPN they will have all of it connected. If the IPsec VPN is not secured properly, an infection on one of the computers could spread through to the corporate WAN. SSL VPNs are not affected by this as they work at higher layers of network.
Remote workers who use IPsec VPNs must often overcome firewalls which restrict their access. It may be impossible to connect via IPsec from a hotel, co working area, or partner location due firewall restrictions. Connecting to IPsec from home is another problem, since some Internet providers do not allow IPsec traffic.
An IPsec VPN service provider says that IPsec VPNs are plagued by several more problems. If you are crossing a large distance, like an ocean, the packet loss rate and latencies can often make some applications inaccessible. Plus, connecting remote workers via the Internet public to corporate WANs is not always reliable regardless of distance.
IPsec VPNs do have their disadvantages. However, they're not unsurmountable. With an optimized WAN, or Network as a Service solution from Aryaka such as its IPsec solution, you get improved reliability at a fractional cost of MPLS. IPsec VPN solution combines networkas-a-service and WAN optimization to deliver a private and optimized WAN. This enables you to get superior performance and reliability over long distances.
