VPN VS. ZTNA VS. SDP VS. NAC: WHAT’S THE DIFFERENCE?

These days, shopping for agile, enterprise-grade secure network access solutions
can be likened to spooning through a bowl of alphabet soup. Beyond understanding
all the acronyms, what’s most important when it comes to safeguarding access to
your data and workloads by anyone from anywhere, anytime?

Share



You’re certainly familiar with the ins and outs of virtual private network (VPN)
and network access control (NAC) solutions. Software-defined perimeter (SDP) and
Zero Trust Network Access (ZTNA) are newer industry terms that you also likely
know about but might not yet use to augment or replace older technology in your
network security stack.

One thing’s for sure: if you want comprehensive, adaptive secure network access,
you need to understand what each of these network security solutions is capable
of and where they differ. Some have served their purpose and are headed for the
sunset. Others are modern options designed to handle the evolving threat
landscape and meet the “now and next” scalable secure access needs of complex
and dispersed hybrid IT ecosystems.

Here we demystify the most common secure access options to help you make a more
informed decision about where to take your network security strategy.

WHAT IS A VIRTUAL PRIVATE NETWORK (VPN)? POPULAR, BUT NOT SECURE ENOUGH


VPNs have been a network security staple for more than 25 years and in the “old
world” of defined perimeters and physical offices, they sufficed. But they
weren’t built to protect hybrid enterprise environments and workforce sprawl and
now come with significant performance and security flaws that create
vulnerabilities. Even the National Security Agency (NSA) has previously warned
about VPN limitations and potential vulnerabilities.

Virtual private networks can only scale with more hardware (physical or
virtual), which means a major investment of capital and time. And they’re
famously temperamental, with connectivity and latency issues that throttle
productivity. Additional VPN limitations include:

 * Exposed ports: VPNs can be easily found and queried to discover the
   manufacturer and version, paving the way for threat actors to get in using
   common hacking tools
 * Over-privileged access: VPNs are dependent on overly complex rules to prevent
   lateral movement
 * Limited throughput: a typical VPN maxes out below 1Gbps which adds extra cost
   and complexity
 * Vulnerable to man-in-the-middle attacks: VPNs don’t validate certificates on
   both sides of the communication path
 * Centralized architecture: users coming into a central VPN access point are
   routed to the ultimate destination on the backend over some type of wide area
   network (WAN) … a topology that adds latency, causes performance issues,
   frustrates users and creates complicated routing dependencies
 * Lack dynamic scale: VPNs must be architected to handle a certain volume of
   remote users and can’t dynamically scale up or down to handle unforeseen user
   fluctuations

WHAT IS NETWORK ACCESS CONTROL (NAC)? IT ONLY ADDRESSES PART OF THE ISSUE


Like VPNs, network access control solutions are antiquated technology designed
for a time when most people were in the office. They restrict access to endpoint
devices that adhere to a defined security policy and perform authentication and
authorization before granting access. However, NAC solutions also fall short:
they can’t segment a network and can only protect on-premises devices … and that
means they only offer a partial solution.

While providing a barrier to entry, NAC solutions are ineffective when it comes
to protecting an environment once user access is granted. Over the years, NAC
technology has become less effective and therefore isn’t seen as a long-term
solution to secure your network access. Ultimately, network access control
flounders for several reasons:

 * Can’t provide fine-grained least privilege access and rely on existing
   network segmentation or VLANs (Virtual LAN)
 * Have limited ability to make access decisions based on user context
 * Don’t provide secure, encrypted communications between clients and services
 * Must be used with another solution (such as a VPN) for remote users, which
   adds more cost, complexity and administration
 * Aren’t practical to manage or scale due to the IT administration required to
   add devices and firewall rules for networks with large amounts of diverse
   users and devices that constantly change
 * Don’t enable cloud security

WHAT IS SOFTWARE-DEFINED PERIMETER (SDP)? A MORE SECURE ALTERNATIVE


After decades of use, VPNs and NACs have taught some lessons and paved the road
for a new, more secure way of granting access to networks.

Using Zero Trust principles—meaning no user or device is trusted until
authenticated and no resources are visible unless access is
granted—software-defined perimeter creates one-to-one connections between users
and the resources they need—and only the resources they need—to do their work.
And as the name implies, SDP is a software-defined solution rather than a
hardware solution, making it very flexible and scalable for multifaceted hybrid
IT environments.

SDP solutions were created to enforce the principle of least privilege, which
reduces the attack surface by making all resources invisible unless a user is
authorized and authenticated. A software-defined perimeter also surveys the
environment and creates entitlements and the appropriate access level for each
user in near real-time and continuously re-evaluates operational context, not
just at the initial request.

WHAT IS ZERO TRUST NETWORK ACCESS (ZTNA)? REFINING THE SOFTWARE-DEFINED
PERIMETER


Zero Trust Network Access, the newest network security industry term, is now
used interchangeably with software-defined perimeter to distinguish the more
secure “authenticate first, connect second” principle of least privilege.

ZTNA is the most effective secure access method available. In contrast to a
“default allow” mode of VPNs, NAC and firewalls, ZTNA is based on Zero Trust
theory and takes a “default deny” approach to digital resources. ZTNA and SDP
are built on three core pillars:

 1. Identity-centric: designed around the user identity, not the IP address, and
    requires user authentication before granting network access
 2. Zero Trust: applies the principle of least privilege to the network and
    users by using micro-segmentation to make unauthorized resources invisible
 3. Cloud-centric: engineered to operate natively in the cloud and deliver
    scalable security

ZTNA is quickly becoming the standard for network access across the hybrid
workplace for enterprise environments and workforces. In fact, according to
Gartner, “by 2024, at least 40% of all remote access usage will be served
predominantly by Zero Trust Network Access, up from less than 5% at the end of
2020.

And Zero Trust maturity is paying off, as stated in the Cost of a Data Breach
Report 2021 by IBM Security and the Ponemon Institute. The average cost of a
data breach was 35% lower ($1.76M) per breach for organizations “in the mature
stage of Zero Trust deployment” compared to those without Zero Trust deployed.

INDUSTRY-LEADING ZTNA: APPGATE SDP


Appgate SDP delivers industry-leading Zero Trust Network Access to anything from
anywhere by anyone. It requires users to be authenticated across a range of
identity-centric and context-based parameters, such as role, time, date,
location and device posture, before allowing access to enterprise resources …
which prevents unsanctioned lateral movement.

Working with your existing security ecosystem to enforce Zero Trust principles,
Appgate SDP features a single policy decision point that controls access across
your organization’s entire IT ecosystem. In addition, exceptional API
integrations mean less rip and replace and more augment and optimize to
strengthen and simplify access controls by putting existing systems and data to
work.
