In recent years, VPNs have been marketed as an essential shield for online security and privacy. Bold claims promise total anonymity, protection from hackers, and unbreakable encryption. Yet, as we move deeper into 2026, a growing chorus of experts—including the U.S. Cybersecurity and Infrastructure Security Agency (CISA)—is pushing back. The message is clear: for most people, relying on a VPN as your primary security tool is misguided at best and risky at worst. Here’s why it’s time to rethink—or even stop—using a VPN purely for “security.”
VPNs Don’t Deliver Comprehensive Protection
One of the biggest myths is that a VPN acts like an all-in-one security suite. In reality, it only encrypts your internet traffic between your device and the VPN server. It does nothing to stop:
- Malware, viruses, phishing, or ransomware. Malicious files or links can still reach your device through the encrypted tunnel. Once there, they execute regardless of the VPN.
- Browser fingerprinting, cookies, or account-based tracking. Sites identify you through device details, login sessions, and behavior patterns—not just your IP address.
- End-to-end threats. Most websites already use HTTPS, encrypting content from your device to the destination. Your ISP sees domain names (like “example.com”), but not full page content or passwords.
In everyday scenarios on home Wi-Fi or mobile data with HTTPS sites (now the vast majority), the additional encryption from a VPN adds little meaningful protection.
The Real Danger: Shifting—and Often Increasing—Risk
CISA’s updated Mobile Communications Best Practice Guidance (November 2025) explicitly advises against personal or commercial VPNs for mobile devices, especially for highly targeted individuals like government or military personnel. The core warning: “Personal VPNs simply shift residual risks from your internet service provider (ISP) to the VPN provider, often increasing the attack surface.”
Why the increase in risk?
- Many VPN providers—particularly free or poorly vetted ones—have questionable security practices, weak auditing, or histories of data leaks.
- You’re funneling all your traffic through a single third party that could be compromised, subpoenaed, or simply incompetent.
- “No-logs” claims aren’t always verifiable; some providers have been caught logging despite promises.
This creates a single point of failure. If the VPN is breached, attackers gain visibility into your entire browsing activity—potentially more than your ISP ever had.
When VPNs Still Make Sense (But Aren’t “Security”)
VPNs aren’t useless—they’re just oversold. They shine in specific, narrow cases:
- Protecting traffic on public Wi-Fi (cafes, airports) from local snooping.
- Bypassing geo-restrictions for streaming or accessing censored content.
- Hiding torrenting or other activities from ISPs that throttle or send notices.
- In high-censorship regions where ISPs heavily monitor users.
Even then, choose carefully: opt for audited, no-logs providers like Mullvad, ProtonVPN, or IVPN over heavily marketed services with unproven claims.
Better Alternatives for Real Security in 2026
If ditching blanket VPN reliance for security, focus on proven layers:
- Strong antivirus/malware protection with real-time scanning.
- HTTPS enforcement (already default on modern browsers).
- Unique, strong passwords managed by a password manager, plus passkeys and 2FA everywhere.
- Browser extensions like uBlock Origin for ad/malware blocking and privacy hardening.
- Encrypted DNS (e.g., Cloudflare 1.1.1.1 or Quad9) to prevent ISP DNS snooping.
- For extreme threats: tools like Tor for anonymity.
For mobile users, CISA recommends features like Apple’s iCloud Private Relay (Safari-only) over third-party VPNs.
The “VPN as ultimate security” narrative stems from outdated marketing that hasn’t kept pace with reality. In 2026, with widespread HTTPS, evolving threats like spyware targeting messaging apps, and official warnings from agencies like CISA, a personal VPN often provides a false sense of security while introducing new vulnerabilities.
Stop treating VPNs as a magic shield. They’re a tool for specific privacy needs—not a substitute for good security hygiene. Evaluate your actual threat model: for most everyday users browsing at home or on mobile data, you’re likely safer without one. If your situation involves public networks, censorship, or sensitive activities, a reputable VPN can still play a role—just don’t bet your security on it alone.
