Why are companies adopting ZTNA?

There are number of factors that are driving the need for ZTNA:

Companies of all sizes are moving to a hybrid application deployment model, adopting cloud services in various capacities, whether it be common SaaS applications like Microsoft 365, Zoom or Salesforce or entire digital transformation projects centered around SaaS, PaaS and IaaS.

Cloud services break traditional security models based on a fixed network perimeter. As cloud services are hosted by third parties rather than in the corporate data center, traditional network security technologies offer insufficient protection for cloud-enabled environments.

The combination of the exposure of cloud services to the public internet, a sophisticated threat landscape and business operational trends like remote working and BYOD mean that companies need to actively manage connections to their cloud environment.

The use of IP lockdown hides corporate services from unauthorized parties while risk-aware access controls ensure that a device meets the desired security requirements, thereby enhancing security for your cloud services.

74% of CFOs intend to permanently shift some employees to remote working post pandemic

Much of digital transformation is about enabling workers, promoting productivity, and removing friction from the end-user experience, but this shouldn’t come at the expense of security. People want to work on their terms, whether that be from their corporate-provisioned laptop or their personal smartphone.

The workforce has also become more complex with agencies, partners and suppliers forming part of the total workforce. In these circumstances, it is not always possible to exert full control over devices managed by another organization.

Ultimately, you want to make sure that regardless of ownership, a device is healthy before it connects to your environment. ZTNA enables any secure device, managed or not, to access applications by using risk-aware access policies to detect compromised devices.

77% of employees use their personal device when working regardless of whether there is a BYOD policy or not

The COVID pandemic has ushered in a new era of working and every organization is trying to work out how best to promote growth and productivity when workers, devices and services are widely distributed.

Regardless of whether your workers are in the office or working remotely, the user experience should be normalized and security and access policies should be consistently applied.

Zero Trust Network Access (ZTNA) enforces consistent access and security policies to plug gaps in security. ZTNA eases the management overhead of having multiple point solutions by offering a centralized platform to manage all devices, applications and users.

79% of respondents to an IDG survey noted that remote working has exposed them to cyber risks

VPN has been a trusty mainstay of corporate infrastructure for decades. It was an effective solution when all corporate services sat onsite and users just needed a secure connection to the corporate network from a managed computer. But this is not the working world of today.

Cloud services are prevalent, BYOD programs continue to be adopted and corporate ecosystems need to be extended to suppliers, partners and other third parties. VPN is difficult to manage, insecure by design and delivers a poor user experience, it’s simply not suitable for the modern environment.

Gartner’s Market Guide for Zero Trust Network Access (ZTNA) positions ZTNA as a long-term replacement to traditional VPN, offering precise access control for applications hosted on-premises and in the cloud.

By 2023, 60% of enterprises will phase out most of their remote access VPNs in favor of ZTNA

Overly privileged accounts are increasingly becoming targets of cyber attacks, so restricting user accounts to only what is needed is an important tactic in reducing an organization’s attack surface. Not only does privilege management mitigate the impact of account takeovers, but also the spread of malware and other cyber threats.

The principle of least privilege access is a core component of Zero Trust Network Access, enabling application-specific access once an assessment of the user identity, device health and other contextual signals are considered. The identity-centric nature of Zero Trust Network Access (ZTNA) enables application-specific access for cloud applications.

72% of respondents reported that managing identities has become even more difficult with a remote workforce

Zero Trust FAQs

Gartner defines Zero Trust Network Access (ZTNA) as “products and services that create an identity- and context-based, logical-access boundary encompassing a user and an application or set of applications.”

The two main ZTNA architectures are Endpoint-Initiated ZTNA, otherwise referred to as a Software-Defined Perimeter (SDP) and Service-Initiated ZTNA, also known as Reverse-Proxy. The Zero Trust Architecture you choose largely depends on the use case you have for ZTNA.

According to Gartner, ZTNA has piqued the interest of organizations seeking a more flexible alternative to VPNs and those seeking more precise access and session control to applications located on-premises and in the cloud.

The efficacy of remote access solutions can be judged by three criteria: strength of security, ease of management, and end-user experience. ZTNA is seen as the next generation of remote access technologies because it resolves many of the security, management, and user experiences shortcomings that come in tow with VPN.

Secure Access Service Edge or SASE, pronounced ‘sassy’, is an architecture that can be thought of as a network security fabric allowing users to securely work on any device, any application, anywhere at any time.
