The line between network privacy and endpoint security is blurring. VPNs, long essential for encrypted tunneling and geo-spoofing, are increasingly bundling antivirus capabilities—creating unified shields against both remote attacks and local malware. ZDNET's latest deep dive evaluates these hybrid tools, testing their ability to deliver robust protection without compromising performance.

Why Hybrid Solutions Matter

"Combining VPN encryption with real-time threat scanning addresses two critical attack vectors simultaneously: data interception during transmission and malicious payloads on devices," explains ZDNET's testing team.

Traditional VPNs mask IP addresses and encrypt traffic but ignore downloaded malware. Standalone antivirus tools lack network-layer defenses. Bundled solutions like Surfshark One ($2.49/month) and NordVPN Threat Protection Pro ($4.39/month) bridge this gap, offering:
- Encrypted connections (AES-256, WireGuard protocols)
- Real-time malware scanning (files, processes, network traffic)
- Phishing/ad blocking
- Cross-platform coverage (Windows, macOS, Linux, mobile)

Top Performers Dissected

ZDNET's testing prioritized:
1. Threat Detection Rates: Malware blocking efficacy during downloads and browsing
2. Privacy Assurance: DNS/IPv6 leak tests and jurisdiction analysis
3. Performance Impact: Speed loss during 4K streaming/P2P transfers
4. Usability: Configuration depth vs. accessibility

Solution Standout Feature OS Support Avg. Speed Loss Threat Block Rate
Surfshark One Unlimited devices + Alternative ID Win, Mac, Android 8% 98%
NordVPN Threat Protection Pro + Password Mgr Win, Mac 3% 99%
PIA Custom encryption + SOCKS5 proxy Windows only 48% 95%
CyberGhost Wi-Fi auto-protection + Server opt. Windows only 15% 96%

Key Findings:
- Surfshark leads for budget-conscious teams needing multi-device coverage, though its Panama jurisdiction raises eyebrows among privacy purists.
- NordVPN’s proprietary NordLynx protocol delivered near-native speeds during tests, ideal for latency-sensitive tasks.
- PIA’s open-source architecture appeals to engineers wanting protocol customization but suffers significant speed drops.

The Performance Paradox

VPN encryption inherently impacts throughput, but antivirus processes compound resource drain. During ZDNET’s stress tests:
- Systems with sub-8GB RAM saw 20%+ CPU spikes during full scans + VPN tunneling
- NordVPN’s lightweight implementation minimized overhead (ideal for DevOps workflows)
- Windows-centric tools like CyberGhost and PIA neglect Linux users—a critical gap for cloud infrastructure management

Implementation Insights

For technical teams evaluating these bundles, consider:

# Check VPN + AV compatibility with existing stack
sudo systemctl status antivirusd && openvpn --config client.ovpn
  • Jurisdiction Risks: US-based PIA operates under Five-Eyes oversight; Surfshark/NordVPN use Panama/Romania for stricter privacy.
  • API Integration: NordVPN and Surfshark offer CLI tools for automated deployment (e.g., Kubernetes node security).
  • False Positives: NordVPN’s aggressive Threat Protection occasionally blocked legitimate dev tools—requiring manual whitelisting.

Beyond the Big Names

For specialized use cases:
- Bitdefender Premium Security ($79/year) excels in heuristic analysis for Windows servers
- Malwarebytes Privacy VPN prioritizes mobile SDK integration for app developers

The Evolving Threat Landscape

As credential stuffing attacks surge 183% YoY (per ZDNET data), these converged tools represent a pragmatic shift. They’re not replacements for enterprise EDR solutions but offer compelling protection for distributed teams and individual developers navigating public Wi-Fi or sketchy repositories. Just ensure your pick aligns with both your threat model and stack requirements—because in security, half measures invite full breaches.
