In the era of remote work and distributed IT environments, a traditional VPN is no longer sufficient security. Encrypting traffic is only one layer of protection, and modern threats require a more sophisticated approach. Phishing attacks, account takeovers and malware can effectively bypass simple network security. Palo Alto Networks offers multi-layered protection that realistically reduces the attack surface and controls access in real time.
Key findings
-
A VPN by itself does not protect against phishing, malware or account takeover.
-
Palo Alto Networks combines VPNs with Zero Trust, segmentation and behavior analysis.
-
The protection covers both users, devices and applications.
-
Multi-layered security is the foundation of cyber resilience.

Summary
Why a VPN is not enough
A classic VPN creates a secure tunnel between a user’s device and the corporate network. The problem is that once authenticated, the VPN doesn’t control what the user does on the network – or whether their device is secure. If the computer is infected, the VPN becomes a conduit for the threat to go straight into the company’s environment.
In addition, many companies today use the cloud and SaaS applications that are accessed outside the VPN. This means that protection needs to go further than the tunnel itself.
Typical threats that bypass a traditional VPN
-
Phishing and account takeover – the user authenticates correctly, but his data is already in the hands of the attacker.
-
Malware – malware enters through infected devices and spreads through the network.
-
Lack of segmentation – access to the entire network after logging in increases the impact of a potential incident.
-
No contextual control – The VPN does not assess the reputation of the device or the user’s behavior.
Palo Alto Networks – a layered approach
Palo Alto Networks proposes a model in which the VPN is just one element of protection. The key layers are:
-
Zero Trust Network Access (ZTNA) – each access attempt is verified for identity, device and context.
-
Traffic inspection and threat analysis – real-time detection of suspicious activity.
-
Access segmentation – the user gets access only to certain resources.
-
Integration with security systems – central management of policies and rapid response to incidents.
Examples of applications
-
Remote teams – protecting access to the corporate environment from anywhere.
-
Multi-branch companies – consistent security control without the need for extensive infrastructure.
-
Regulated industries – implementing Zero Trust policies required by safety standards.
-
Hybrid environments – protecting both local networks and cloud applications.
FAQ
Are Palo Alto Networks replacing the classic VPN?
No – it extends its capabilities by adding layers of protection that the VPN itself does not provide.
Does the solution work with different operating systems?
Yes, it is compatible with popular platforms and mobile devices.
Does the implementation require major infrastructure changes?
No. Palo Alto Networks’ solutions can be integrated into existing architecture.
Summary
A VPN is an important piece of protection, but it is not enough on its own to ensure security in today’s threat landscape. Palo Alto Networks combines VPN with Zero Trust, segmentation and contextual analysis to create a complete protection strategy that effectively minimizes risk.
