About Perimeter 81

Perimeter 81 is a cloud-based, Secure Network as a Service provider, driven by
the mission to transform secure network access for the modern and distributed
workforce. Built from scratch based on input from security leaders needing a
change from legacy VPN technology, Perimeter 81’s user-friendly interface, unified
management and seamless integration with major cloud services, allows employees
to securely access on-premise and remote resources, and gives companies of all
industries and sizes the power to be fully mobile and confidently cloud-based.

Traditional VPNs and the Need for
Software-Defined Perimeters

At the core of the Perimeter 81 platform is the
Software Defined Perimeter, a security that model
addresses traditional VPN limitations while providing
a flexible cloud-based platform, device and application
configurability as well as accessibility, increased security,
privacy and user-access control granularity and analytics.


Within the SDP security model, the concept of Zero
Trust or micro-segmentation functions as a trust
broker between a client and a gateway by establishing
a Transport Layer Security (TLS) tunnel terminating
inside the network perimeter, thereby allowing access to
applications and services.

According to the Cloud Security Alliance (CSA), Software
Defined Perimeters provide “the ability to deploy
perimeters that retain the traditional model’s value of
invisibility and inaccessibility to “outsiders,” but can be
deployed anywhere – on the internet, in the cloud, at
a hosting center, on the private corporate network, or
across some or all of these locations. The SDP brings
together standard security tools including PKI, TLS,
IPsec, SAML, and standards, as well as concepts such as
federation, device attestation, and geo-location to enable
connectivity from any device to any infrastructure.”
