Introduction: A Warning Against Digital Doors Left Open
For years, virtual private networks (VPNs) have been considered a critical security tool, allowing employees, contractors, and government workers to safely connect to internal systems from remote locations. However, as cyber threats have evolved, many older VPN systems have become less like secure tunnels and more like exposed digital entrances waiting for attackers to exploit.
U.S. Senator Ron Wyden of Oregon is now calling for a major transformation in how federal agencies handle remote access security. He has urged government leaders to eliminate outdated, internet-facing VPN systems and replace them with modern security models based on zero-trust architecture.
Wyden’s warning comes after years of high-profile cyberattacks targeting VPN appliances, firewalls, and remote-access technologies. His message is clear: government networks cannot continue depending on aging systems that create predictable entry points for sophisticated hackers.
Senator Wyden Calls for the Removal of Vulnerable Public-Facing VPN Systems
Senator Ron Wyden has urged the Office of Management and Budget (OMB), the Cybersecurity and Infrastructure Security Agency (CISA), and the National Institute of Standards and Technology (NIST) to launch a coordinated effort to remove outdated VPN technologies from federal environments.
In a letter sent to federal cybersecurity leaders, Wyden argued that government agencies and contractors have repeatedly suffered serious breaches because they continue relying on legacy VPN servers exposed directly to the public internet.
According to Wyden, these systems act as a digital “front door” for attackers. When a VPN gateway is visible online, hackers can continuously scan it, search for vulnerabilities, steal credentials, and attempt unauthorized access.
The senator believes that maintaining these systems creates unnecessary risk when stronger alternatives already exist.
Why Legacy VPN Technology Has Become a Security Problem
Traditional VPN systems were designed for a different era of cybersecurity. The original idea was simple: create an encrypted connection between a remote user and an internal network.
However, modern cyberattacks have changed the situation dramatically.
Attackers no longer rely only on breaking encryption. Instead, they target the VPN appliance itself. If the device contains an unpatched vulnerability, attackers can bypass authentication, steal session information, or gain access to sensitive internal resources.
Many organizations still operate under a “castle-and-moat” security philosophy. This model assumes that once someone enters the network perimeter, they can be trusted.
Wyden argues this approach is outdated because modern attackers often compromise legitimate accounts or devices before entering a network.
Major Cyberattacks Highlight the Danger of VPN Exposure
Wyden referenced several major incidents to demonstrate the risks associated with internet-facing remote-access systems.
One example involved the ArcaneDoor campaign, where attackers targeted Cisco security appliances. Another involved Fortinet vulnerabilities that exposed credentials through compromised VPN gateways.
Attackers have also exploited weaknesses in remote-access products from companies such as Ivanti and Check Point, demonstrating that VPN appliances remain a high-value target.
These incidents reveal a repeated pattern:
A vulnerability is discovered.
Organizations struggle to patch quickly.
Attackers exploit exposed systems before defenses are updated.
Emergency security directives are issued after damage occurs.
Wyden argues that this cycle is unsustainable.
The Government’s “Whack-a-Mole” Cybersecurity Problem
According to Wyden, federal cybersecurity teams have become trapped in a constant reaction cycle.
Instead of preventing attacks by removing vulnerable technologies, agencies are repeatedly forced to respond after vulnerabilities are discovered.
CISA has frequently issued emergency directives requiring agencies to quickly patch critical vulnerabilities. While these actions can reduce immediate danger, Wyden believes they treat the symptoms rather than the root cause.
The senator described the current approach as an endless game of “whack-a-mole,” where defenders repeatedly eliminate one problem only to face another identical threat later.
His argument is that outdated remote-access technology itself has become the problem.
Zero Trust: The Security Model Wyden Wants Federal Agencies to Adopt
Wyden is calling for a nationwide federal transition toward zero-trust architecture.
Unlike traditional VPN-based security, zero trust follows a simple principle:
Never trust. Always verify.
Under this model:
Every user must continuously prove identity.
Every device must meet security requirements.
Access is limited based on specific needs.
Network visibility is reduced.
Compromised accounts have fewer privileges.
Instead of creating a large gateway into an organization, zero-trust systems provide controlled access to individual applications and resources.
This reduces the impact of stolen credentials and makes it harder for attackers to move laterally through networks.
Modern Remote Access Could Make Attack Surfaces Invisible
Wyden highlighted an important advantage of modern remote-access technologies: reducing visibility.
Traditional VPN servers are often publicly discoverable. Attackers can scan the internet and identify vulnerable systems.
Modern approaches can remove this exposure by hiding access points and requiring stronger identity verification before communication begins.
The concept is similar to removing a visible door from a building and replacing it with a controlled authentication system that only appears when authorized.
For cybersecurity teams, reducing visibility means reducing opportunities for attackers.
Wyden’s Proposed Three-Part Federal Cybersecurity Transformation
Wyden outlined specific actions he believes federal agencies should take.
- CISA Must Create a Binding Migration Deadline
The senator wants CISA to issue a binding operational directive requiring agencies to remove legacy public-facing remote-access systems within two years.
This would create a clear timeline instead of allowing agencies to delay modernization indefinitely.
2. NIST Must Establish Zero-Trust Implementation Standards
Wyden believes NIST should provide detailed technical guidance for agencies transitioning away from traditional VPN models.
Clear standards would help organizations understand:
Which technologies should replace legacy VPNs.
How identity verification should work.
How access controls should be implemented.
How security teams should measure progress.
- OMB Must Change Federal Technology Spending Rules
Wyden also wants OMB to ensure federal cybersecurity budgets prioritize zero-trust solutions.
He proposed that agencies and defense contractors should not purchase network-edge security products unless vendors can prove compliance with NIST zero-trust standards.
This would force technology providers to build security into products rather than relying on customers to fix weaknesses later.
Deep Analysis: Understanding the Future Beyond VPN Security
Cybersecurity Commands and Defensive Checks
Security teams can identify exposed VPN infrastructure using several defensive techniques.
Search for public-facing VPN services:
nmap -sV -p 443,500,4500 target-domain.com Check SSL/TLS configuration:
openssl s_client -connect vpn.example.com:443 Search internet exposure:
shodan search "vpn gateway organization" Review active network connections:
netstat -tulpn Check suspicious authentication attempts:
grep "failed login" /var/log/auth.log
Why VPN Appliances Continue Becoming Prime Targets
VPN gateways are attractive because they sit directly at the network boundary.
A successful compromise can provide attackers with:
Remote access privileges.
Internal network visibility.
Authentication tokens.
Employee credentials.
A pathway to ransomware deployment.
For cybercriminal groups and state-backed attackers, compromising a VPN appliance can be more valuable than attacking individual computers.
Zero Trust Is Becoming the New Cybersecurity Foundation
The transition away from traditional VPNs represents a larger industry movement.
Companies and governments worldwide are moving toward identity-based security rather than network-based trust.
The future security model will focus less on protecting a perimeter and more on continuously validating every interaction.
The question is no longer:
“Are you inside the network?”
The new question is:
“Are you authorized to access this specific resource right now?”
What Undercode Say:
The debate around replacing legacy VPN systems is not simply about updating technology. It represents a fundamental change in how governments think about cybersecurity.
For decades, organizations believed strong network borders could protect valuable information.
That strategy worked when employees worked inside offices, devices were controlled, and threats were predictable.
The modern environment is completely different.
Remote work, cloud services, mobile devices, and international cybercriminal networks have destroyed the idea of a reliable network perimeter.
A VPN gateway that is visible on the internet is effectively an invitation for attackers to test their skills.
Every exposed system becomes a potential battlefield.
The problem is not only vulnerabilities.
The deeper issue is architectural design.
Many VPN systems assume that authentication happens once and trust continues afterward.
Modern attacks prove this assumption is dangerous.
Attackers steal passwords.
They hijack sessions.
They compromise trusted devices.
They imitate legitimate users.
Zero trust addresses this reality by removing permanent trust.
Every request becomes a security decision.
Every connection becomes an opportunity for verification.
Senator Wyden’s proposal reflects a broader cybersecurity evolution already happening across major organizations.
The future will not be defined by stronger walls.
It will be defined by smarter identity controls.
However, replacing government-wide VPN infrastructure will not be simple.
Large agencies often operate thousands of systems built over decades.
Legacy applications may depend on traditional network access.
Budget limitations can slow modernization.
Cybersecurity teams are already overwhelmed managing current threats.
A two-year migration deadline would create pressure but also require significant investment.
The technology industry must also accept responsibility.
Security cannot depend only on customers applying emergency patches.
Vendors must build products that are secure by design.
Federal purchasing power could become one of the strongest forces pushing the cybersecurity market toward safer solutions.
If government contracts require zero-trust compliance, vendors will have a strong incentive to improve their platforms.
The VPN problem also highlights a larger lesson.
Cybersecurity failures are often caused not by a single mistake but by outdated assumptions.
Organizations must constantly question whether yesterday’s solutions are prepared for tomorrow’s attacks.
The removal of legacy VPN systems could become one of the most important federal cybersecurity modernization efforts in years.
The challenge will be turning political recommendations into practical implementation.
Cybersecurity transformation requires technology, funding, leadership, and patience.
But continuing with vulnerable systems creates a greater risk.
The digital battlefield has changed.
Government networks must change with it.

Prediction
(+1) Federal agencies will increasingly move away from traditional VPN systems and adopt zero-trust security frameworks.
Governments worldwide are already investing heavily in identity-based security, cloud security, and stronger access controls. Wyden’s proposal could accelerate this transformation inside U.S. federal networks.
(+1) Cybersecurity vendors will redesign remote-access products around invisible infrastructure and identity verification.
Future security platforms will likely focus less on network gateways and more on adaptive authentication systems.
(-1) Many agencies may struggle to complete migration deadlines because of legacy systems and budget challenges.
Large government environments often depend on older technologies that cannot be replaced quickly without operational risks.
(-1) Attackers will continue searching for weaknesses in new security models.
Even after VPN modernization, cybercriminals will shift toward identity theft, cloud attacks, and supply-chain compromises.
The future cybersecurity battle will not disappear after VPN replacement. It will simply move to a new battlefield.
