Compare the advantages of implementing an SDP solution in place of a traditional VPN.
Eliminate hardware VPNs with Perimeter 81’s secure Software-Defined Perimeter architecture.
A software-defined perimeter is a hardware-less type of architecture that creates an internal network quarantined from the outside by a perimeter comprised of a variety of firewalls, which prevents users from coming in without verification. It then allows granular control over specific resource access once users are within the network.
SDP works by containing a company’s IT assets inside a closed network of firewalls that do not let unauthorized users inside. The software foundation of SDP means that both local and cloud resources can be protected from outside access, with the SDP controller being manipulated by IT to determine which users can access which resources once authorized.
A VPN, or virtual private network, is a product that helps users connect to web pages, applications, and other resources safely. It keeps their connection and data private as long as it’s active, and allows them to route (and anonymize) their traffic through different globally-placed servers.
A VPN creates a secure tunnel between a user’s PC and the resource they are trying to access (an application, web page, etc.). The tunnel contains traffic that is encrypted by one of many different protocols including IPSec, SSL, WireGuard and others, keeping one’s data private as they interact across the web.
SDP is different from VPN largely due to the way that it enables custom internal network access policies, while VPNs are meant to provide unlimited network/resource access to users. VPNs also limit visibility across the network for IT, while SDP enables it. Another key difference is that policies are able to be automated with an SDP, and this function is rare on a VPN.
SDP is a good VPN alternative, as is IAM (Identity Access Management) but only as a complement to VPNs. Enterprises might also try PAM or VPAM - which are Privileged and Vendor Privileged Access Management, respectively.
Yes, SDP is an effective alternative to VPN, as it also privatizes traffic over the network, but includes more in-depth functionality and auditing utilities.
