Enterprise remote access has long relied on a simple assumption: once a user connects to the intranet through a VPN, the user is “trusted.” The firewall verifies the account and password at the boundary. After verification, the user obtains network-level access permissions and can access intranet resources as if in the office.
This assumption is now full of holes in today’s network environment.
An employee connects to the VPN through public Wi-Fi in a café, and his endpoint may already be infected with malware; an outsourced worker uses a personal computer to connect to the intranet, and the device may be running pirated software; a departing employee logs in one last time before permissions are revoked and downloads core materials in bulk. The common problem in these scenarios is that VPN only verifies “who you are,” not “whether your device is trusted,” “whether you need to access this resource,” or “what you did after access.”
The core idea of Zero Trust is precisely the negation of the above assumption: trust no default access; every access must be verified. But the term “Zero Trust” has been overused in recent years, and many solutions merely rename VPN without changing the underlying trust model.
The design starting point of Ping64 Zero Trust Gateway Lite is to make Zero Trust truly land as usable remote access capability—not to make VPN more complex, but to achieve stricter control in a simpler way. Its capabilities are developed around three layers: networking, access control, and application publishing, and are deeply linked with identity management, endpoint security, and audit tracing within the integrated office security platform.
I. Networking: Making Remote Access “Connectable, Fast, and Secure”
The first-layer requirement of remote access is “connectability.” Traditional VPN networking often faces complex configuration, slow connection speeds, and high latency, especially in cross-region and multi-branch scenarios, where O&M costs are extremely high.
Ping64 Zero Trust Gateway Lite’s networking capability enables enterprise users to establish remote networking through the Ping64 Zero Trust Gateway, making it simpler and easier to use than traditional networking methods. Administrators do not need to configure complex tunnel parameters, routing rules, or NAT translation. They only need to complete basic configuration on the platform, and after the endpoint installs the client, the networking connection is automatically established.
In terms of connection performance, Ping64 adopts optimized transmission protocols and intelligent routing mechanisms, providing faster connection speeds and lower latency. For remote work scenarios that require frequent access to intranet applications, this difference directly affects work efficiency—when an engineer opens a large design file, a finance staff member queries a business report, or a customer service representative accesses a work order system, connection latency drops from “waiting for seconds” to “nearly imperceptible.”
In terms of security, Ping64 uses more advanced encryption technology with forward secrecy and resistance to downgrade attacks. Forward secrecy means that even if long-term keys are compromised in the future, attackers cannot decrypt data transmitted in the past; resistance to downgrade attacks means the system can reject attempts by attackers to downgrade encryption strength to weak algorithms. These two capabilities make the encryption strength of remote access no longer dependent on “whether the user has configured the correct cipher suite,” but guaranteed by the system by default.
The networking layer solves the “connection channel” problem, but it is only the first step of Zero Trust. Being able to connect does not mean one should connect, and channel security does not mean access is controllable.
II. Access Control
The second-layer requirement of remote access is “only what should connect can connect.” Traditional VPN grants network-level permissions—once connected, users can access all intranet resources within their permission scope. This “coarse-grained authorization” is extremely risky today, with diverse endpoint types and frequent personnel changes.
Ping64 Zero Trust Gateway Lite’s application server access control capability uses policy configuration to ensure that only endpoints with the client installed have permission to access enterprise application services. Any illegal client cannot access them, ensuring that access to enterprise application servers is secure and controllable.
The core design of this capability is “endpoint + identity” dual verification. Access control policies do not simply allow access by user account, but simultaneously verify two conditions: first, whether the user identity is legitimate and whether the user has access permission for the application; second, whether the endpoint initiating the access has the Ping64 client installed and is in a compliant state. Only when both conditions are met is the access request released.
This means that even if an attacker steals a legitimate user’s account and password, if he does not have an endpoint with the Ping64 client installed, he cannot access enterprise applications. Even if an employee uses a personal device, as long as the device has the Ping64 client installed and passes compliance checks, it can obtain limited access permissions according to policy. The granularity of access control is refined from “network level” to “application level,” and from “account level” to “account + endpoint level.”
More importantly, this access control capability shares the same set of security baseline policies with the endpoint security management module within the platform. The endpoint’s compliance status—whether operating system patches meet standards, whether antivirus software is running, whether high-risk software exists—directly affects its access permissions. When endpoint security status changes, access permissions are automatically adjusted without manual intervention by administrators.
III. Application Publishing
The third-layer requirement of remote access is “ease of use.” In traditional VPN solutions, after connecting, users need to remember the IP addresses and port numbers of intranet applications and manually configure access paths. For employees unfamiliar with IT, this is itself a barrier.
Ping64 Zero Trust Gateway Lite’s application publishing capability allows enterprise applications to be published on Ping64, and users can access enterprise application systems through the client application portal. After administrators complete application publishing configuration on the platform, employees see a unified application portal in the client—click to access, without memorizing IP addresses or manual configuration.
The value of this capability lies not only in “convenience,” but also in converging access entry points onto a unified platform. All remote access behavior is initiated through the client portal, and the platform can record the user, endpoint, time, target application, and access result of each access. These records are stored in association with the audit center within the platform, forming a complete remote access audit trail.
Another advantage of application publishing is hiding the intranet topology. After traditional VPN connection, users can see part of the intranet structure, creating risks of scanning and probing. In Ping64’s application publishing mode, users can only see authorized published application portals and cannot discover unpublished intranet resources through scanning. The intranet topology is “invisible” to remote users, greatly reducing the attack surface.
IV. Advantages of the Integrated Platform
Embedding Zero Trust Gateway Lite capabilities into the integrated office security platform provides advantages not in “having one more remote access tool,” but in Zero Trust no longer being an island in the security system.
Linkage with unified identity management. The core of Zero Trust is “continuous identity verification.” Ping64 Zero Trust Gateway Lite’s access control policies share the same set of user, role, and department data with the unified identity management system within the platform. When employees change positions, leave, or have permission changes, access permissions are automatically adjusted, without the need to maintain a separate user list in the Zero Trust gateway. Identity is unified, and permissions are linked.
Linkage with endpoint security management. Another core of Zero Trust is “verifying device trustworthiness.” Ping64 Zero Trust Gateway Lite’s access control shares the same set of security baseline policies with the endpoint security management module. The endpoint’s patch status, antivirus software status, and high-risk software situation directly affect access permissions. Device trustworthiness is not a one-time check result, but a continuous state assessment.
Linkage with behavior auditing. Zero Trust requires “recording every access.” Ping64 Zero Trust Gateway Lite’s access records are stored in association with the audit center within the platform. When the security team investigates an incident, it can simultaneously retrieve the user’s identity information, endpoint status, access records, operation behavior, and file flow records, forming a complete evidence chain.
Linkage with data loss prevention. The ultimate purpose of remote access is to use data. Ping64 Zero Trust Gateway Lite’s access control is linked with the data loss prevention module. When users open sensitive files through remote access, the system automatically triggers protection actions such as encryption, watermarking, download restrictions, and screenshot prohibition. Access control protects “whether one can enter,” while data loss prevention protects “what one can do after entering.”
V. From “Connection” to “Governance”
The maturity of enterprise remote access construction can be divided into three stages.
The first stage is “being able to connect.” Enterprises deploy VPN or similar tools so that remote employees can access the intranet. This stage solves the “connection” problem, but access permissions are coarse-grained, endpoint status is invisible, and access behavior is difficult to trace.
The second stage is “being able to manage.” Enterprises add identity verification, endpoint checks, and access control to remote access, restricting “who can connect, with what device, and what they can connect to.” This stage moves control forward to “before access,” but capabilities are scattered across different systems, with no policy linkage or data interoperability.
The third stage is “being able to govern well.” Enterprises integrate networking, access control, and application publishing on a unified platform, deeply linked with identity management, endpoint security, data loss prevention, and audit tracing. Remote access is no longer an “exception channel” in the security system, but an organic link in the governance closed loop.
What Ping64 Zero Trust Gateway Lite pursues is precisely the goal of the third stage. When the Zero Trust gateway operates collaboratively with unified identity management, endpoint security management, data loss prevention, and behavior auditing on the same platform, enterprises no longer need to make an either-or choice between “remote work efficiency” and “access security.”
The Landing of Zero Trust Lies Not in Concepts, but in Integration
Zero Trust is not a new concept, but truly implemented Zero Trust solutions are few. Many solutions turn Zero Trust into a “more complex VPN”—adding more verification steps, more policy configurations, and more management consoles, without solving the fundamental problems: Are verification results linked with endpoint status? Are access permissions synchronized with identity changes? Is access behavior coordinated with data protection?
The differentiation of Ping64 Zero Trust Gateway Lite lies not in the three functions it provides—networking, access control, and application publishing—but in that these three functions run on the integrated office security platform, sharing the same data foundation and policy engine with identity, endpoint, data, and auditing. Zero Trust is no longer an independent security product, but an organic component of the enterprise’s overall security governance system.
When every remote access connection undergoes dual verification of identity and endpoint, when access permissions automatically adjust with identity and endpoint status, and when access behavior operates collaboratively with data protection policies, Zero Trust truly transforms from a concept into an operable capability. This may be the most pragmatic response to the remote work era.
