Is Your VPN the Biggest Financial Risk in Your Business?

For decades, the Virtual Private Network (VPN) was the trusted gatekeeper for remote access. Today, it’s the primary entry point for attackers. New data for 2025 reveals that internet-facing security tools like VPNs are now implicated in a staggering 58% of all ransomware incidents, making them your company’s most significant cybersecurity liability.

With the average cost of a data breach in the U.S. surging to an all-time high of $10.22 million, relying on outdated VPN technology is no longer a calculated risk; it’s a financial gamble. The question is no longer if your perimeter will be breached, but how you will secure your organization when it is.

Key Takeaways for Leaders:

• VPNs Are the Front Door for Attackers: A significant portion of breaches still begins at the perimeter, with 18% of breaches initiated via unpatched web assets and 12% leveraging exposed remote services (often including VPNs and RDP).
• The Cost of Failure is Catastrophic: The average U.S. data breach now costs over $10 million, with ransomware recovery alone costing an average of $1.53 million, not including the ransom.
• Unmanaged Devices Are the True Perimeter: Attackers now focus on access, with Microsoft reporting that 80% of all reactive incident response engagements involved data collection or staging. Investigations show 28% of all breaches were initiated through phishing or social engineering, vectors often enabled by unmanaged devices.
• The Industry Has Moved On: An overwhelming 81% of organizations are actively moving away from VPNs and plan to adopt a Zero Trust security framework by 2026.

The New Reality: Why Your VPN Is Failing

With hybrid work as the new standard, the idea of a secure internal network protected by a simple wall is a dangerous fantasy. This new reality has exposed the fundamental flaws of VPN architecture, making it indefensible for mid-market businesses.

The #1 Entry Point for Ransomware

The most compelling argument against VPNs is the hard data. They are no longer a defense; they are the preferred target. Because VPNs must be exposed to the internet to function, attackers can scan them relentlessly for vulnerabilities. Once they find one, the design flaw of a VPN becomes a catastrophe.

According to the Microsoft Digital Defense Report 2025, attackers are actively focusing on perimeter gaps: 18% of all breaches were initiated via unpatched web assets and 12% leveraged exposed remote services—two categories that often include VPNs, firewalls, and remote desktop protocols (RDP). This initial access is just the first step: the Report also found that over 40% of ransomware attacks now involve hybrid components, meaning the breach quickly moves from the compromised front door into the cloud and on-premises environments.

• How it works: A VPN grants broad, network-level access, essentially treating the connection like a trusted employee already inside the office.
• Why it fails: This “implicit trust” allows an attacker who breaches the VPN to move laterally across your entire network, steal data, and deploy ransomware without needing to break in again.

This isn’t a theoretical risk. A stunning 92% of business leaders now worry that a VPN vulnerability will directly lead to a debilitating ransomware attack.

The Unmanageable Patching Crisis

For a mid-market company without a 24/7 Security Operations Center (SOC), keeping VPNs secure is nearly impossible. Experts warn that after a new vulnerability is announced, attackers can exploit an unpatched VPN in a matter of hours.

This speed of exploitation is why unpatched systems remain the number one root cause of ransomware infections. Your IT team simply cannot keep pace with the constant threat.

“We’ve seen the security progression clearly: first, exposed remote desktop was the brute force target, then it went behind a VPN. Now, zero-day exploits and MFA fatigue attacks—some getting hit a hundred thousand times a day—are designed to bypass all that authentication. The common thread is the open hole on the public internet. The only way to win is to remove the VPN from the public internet altogether and darken your network.”

Translating Technical Failure into Financial Disaster

The technical shortcomings of VPNs have a direct and severe impact on business continuity and financial stability. For leaders, understanding these numbers is critical to justifying a strategic pivot.

The Soaring Cost of a U.S. Data Breach: $10.22 Million

While global breach costs saw a slight dip, the financial penalty for a breach in the United States surged by 9% to a record $10.22 million. This massive figure is driven by escalating regulatory fines and litigation costs unique to the U.S. market. For a mid-market business, a single incident of this magnitude is an existential threat.

The Real Threat of Ransomware: Operational Downtime

The ransom payment itself is often not the biggest cost. The most devastating consequence is the resulting downtime, which now averages a staggering 24 days.

Imagine your entire operation grinding to a halt for nearly a month. This extended paralysis leads to lost revenue, broken customer trust, and soaring recovery costs. The reality is stark: 60% of small businesses may be forced to close within six months of a major cyberattack.

The Unseen Threat: Your Employee’s Laptop Is the New Perimeter

The most critical shift in cybersecurity for 2025 is realizing that the battle is no longer at your office firewall. It’s on the unmanaged devices your employees use every day.

The Microsoft Digital Defense Report 2025 delivered an insight that underscores the shift: 80% of all reactive incident response engagements involved data collection or staging. Attackers are moving past the network perimeter and gaining access through the endpoint. This is largely driven by employee devices, as investigations found that a significant 28% of all breaches were initiated through phishing or social engineering.

Attackers aren’t wasting time trying to break down your front door anymore. They are walking in through the side entrance such as an employee’s personal laptop or smartphone used for work. A traditional VPN is blind to this; once it authenticates a user’s credentials, it trusts the device completely, allowing a compromised machine full access to your network. This single statistic proves that any security strategy focused only on the network is doomed to fail.

The Strategic Path Forward: From VPNs to Zero Trust

The data is clear: the legacy model is broken. This is why 81% of organizations are actively moving to a Zero Trust security framework.

Zero Trust Network Access (ZTNA) is the architectural successor to the VPN. It operates on a simple but powerful principle: “never trust, always verify.”

Instead of giving a user a key to the entire building (the network), ZTNA gives them a key to a single room (a specific application) for a limited time, and only after verifying their identity and checking that their device is secure.

Your Action Plan: A 3-Step Roadmap for Mid-Market Leaders

Transitioning your security posture is a critical business project. Here is a practical roadmap for moving forward.

1. Phase 1: Mitigate Immediate Risk (First 90 Days)
   • Mandate Multi-Factor Authentication (MFA): The single most effective step you can take today. Enforce MFA on all remote access, especially any remaining VPNs.
   • Control the Unmanaged Edge: Deploy endpoint security that can verify the health of employee devices (BYOD) before they are allowed to connect to company data.
   • Prioritize Patching: Ensure your IT team has a rapid response plan for patching critical vulnerabilities on all internet-facing systems.
2. Phase 2: Redefine Your Perimeter Around Identity
   • Begin a phased ZTNA implementation, starting with your highest-risk users: third-party vendors and contractors.
   • Integrate ZTNA with a modern Identity Provider to make identity, not the network, the new control plane for your security.
3. Phase 3: Decommission Legacy Infrastructure
   • Once ZTNA is proven and operational for your critical applications, create a formal plan to decommission your traditional VPNs.
   • This final step removes the attack surface responsible for over half of today’s ransomware attacks and simplifies your security architecture for the future.

The Choice for 2025

The evidence is overwhelming. The VPN is a 30-year-old technology that is no longer fit for purpose in a world of hybrid work, sophisticated ransomware, and unmanaged devices. Continuing to rely on it is an active choice to accept enormous financial and operational risk.

The strategic pivot to Zero Trust is not just a technology upgrade; it’s a fundamental business decision to build resilience, protect your assets, and secure your company’s future. The industry is moving forward, and the time to act is now.
