Your complete guide to enterprise VPN and Zero Trust Network Access solutions — from Cisco AnyConnect to Cloudflare Zero Trust, always-on VPN, team VPN, free options, and SaaS-based secure remote access for businesses of every size.

💡 10 Things to Know Before Choosing a Business VPN

Enterprise VPN technology is undergoing a fundamental shift. The global VPN market is valued at $44.6 billion, and over 70% of new remote-access deployments now use Zero Trust Network Access (ZTNA) instead of traditional VPN services — up from under 10% in 2021, according to Gartner. This change is driven by three realities: traditional VPNs grant broad network access once authenticated (a major security risk), most enterprise resources now live in cloud environments outside the corporate network, and regulations like GDPR, HIPAA, PCI DSS 4.0, and NIST SP 800-207 increasingly require continuous identity verification. This guide covers both traditional enterprise VPNs and modern Zero Trust alternatives so you can choose the right solution for your business size and security requirements in 2026.

1
What are the best enterprise VPN solutions according to Gartner? Gartner’s 2025 Security Service Edge Magic Quadrant named Zscaler, Netskope, and Palo Alto Networks as Leaders. For traditional enterprise VPN, Cisco AnyConnect (now Cisco Secure Client) is the most widely deployed enterprise VPN globally. Gartner forecasts that ZTNA now accounts for 70%+ of new remote-access deployments.
Gartner tracks enterprise VPN and its successor technology — Zero Trust Network Access (ZTNA) — under the Security Service Edge (SSE) and Zero Trust Network Access market categories. The 2025 Gartner SSE Magic Quadrant placed Zscaler, Netskope, and Palo Alto Networks as Leaders, while Fortinet received the sole Gartner Peer Insights Customers’ Choice recognition for ZTNA in 2025 with a 4.9 out of 5.0 score across 235 reviews. For traditional enterprise VPN, Cisco AnyConnect remains the most widely deployed solution in the world. Gartner Peer Insights also has verified reviews for Cloudflare Access, Cisco Secure Client, Palo Alto GlobalProtect, and other major ZTNA and VPN platforms. The key insight from Gartner data: by 2025, at least 70% of new remote access deployments use ZTNA rather than VPN — a complete reversal from 2021 when ZTNA represented less than 10% of deployments.
2
Is there a free enterprise VPN solution? Cloudflare Zero Trust offers a free plan for up to 50 users. Tailscale offers a free plan for personal use (up to 3 users). ProtonVPN has a free tier for individuals. Google BeyondCorp Enterprise has a free identity-aware proxy for Google Cloud users. WireGuard is a free, open-source VPN protocol.
For small teams on tight budgets: Cloudflare Zero Trust’s free plan covers up to 50 users with identity-based access control, multi-factor authentication, and no VPN hardware needed — making it the most capable free enterprise-grade option. Tailscale’s free Starter plan supports up to 3 users and 100 devices with WireGuard-based mesh networking. ProtonVPN’s free tier provides unlimited data on 3 server locations for 1 device — it is genuinely free with no data selling, funded by paid subscribers. Google Identity-Aware Proxy (Cloud IAP) is completely free and adds a protective layer to apps running on Google Cloud, useful for teams already using GCP. WireGuard is a free, open-source VPN protocol that any IT team can self-host on a server, though it requires technical configuration. Note: “free” for enterprise typically means more IT management overhead or limitations on features like centralized logging and compliance reporting.
3
What is the best VPN for small business remote access? NordLayer (from NordVPN) is the best VPN for small business remote access at $7–$14/user/month. It combines enterprise VPN features (dedicated gateways, SSO, MFA, centralized management) with consumer-grade simplicity. Tailscale and Cloudflare Zero Trust are excellent alternatives, especially if your team is technical.
For a small business team of 5–50 people, NordLayer (formerly NordVPN Teams) is specifically designed for business remote access with dedicated server management, user management, SSO integration via SAML, and the performance of the NordLynx protocol. Pricing starts at $7/user/month for the Lite plan with a minimum of 5 users. Tailscale is excellent for technically capable teams — it creates a peer-to-peer mesh network using WireGuard that requires no central server, sets up in minutes, and is free for small teams. Cloudflare Zero Trust is ideal for teams with web-based applications. For very small businesses or individual remote workers, a business plan from ExpressVPN or NordVPN consumer products also works well, though they lack centralized management features.
4
What is Proton VPN for Business? ProtonVPN for Business is a Swiss-based encrypted VPN service with up to 10 Gbit/s server speeds, AES-256 or ChaCha20 encryption, a strict no-log policy, and a Secure Core architecture that routes traffic through multiple servers. It is trusted by businesses in high-risk sectors worldwide and includes VPN, email, calendar, cloud storage, and password manager as an integrated encrypted suite.
Proton VPN is unique because it is operated by Proton AG in Switzerland, governed by Swiss privacy law — one of the world’s strongest privacy jurisdictions. All servers use full-disk encryption so data cannot be accessed even if hardware is seized. The Secure Core architecture routes traffic through servers in Iceland, Sweden, or Switzerland before leaving the network. ProtonVPN uses AES-256 or ChaCha20 encryption with Perfect Forward Secrecy, meaning even if an encryption key for one session is compromised, past sessions remain protected. ProtonVPN is part of an encrypted suite of tools including Proton Mail, Proton Calendar, Proton Drive, and Proton Pass (password manager) — a complete encrypted work environment. For businesses in healthcare, legal, journalism, or government sectors where client confidentiality is paramount, Proton VPN’s jurisdiction and architecture make it a particularly strong choice.
5
What is ExpressVPN Business / ExpressVPN Teams? ExpressVPN offers business plans called ExpressVPN Teams, providing centralized account management, dedicated customer support, team invoicing, and the same high-performance network (3,000+ servers in 105 countries) as the consumer product. It is best suited for small teams that need reliable global access and ease of use over enterprise security management features.
ExpressVPN Teams is designed for small to medium businesses that need consistent global VPN coverage without the complexity of enterprise ZTNA deployment. The platform uses Lightspeed protocol for fast connections, supports AES-256 encryption, and includes a kill switch and DNS leak protection. Centralized billing and management allow IT administrators to manage licenses, add or remove users, and monitor usage from one portal. ExpressVPN runs its own DNS servers and operates under a verified no-log policy, independently audited by PwC. For larger businesses needing granular access control by application, SSO integration, or compliance-grade logging, a dedicated ZTNA platform like NordLayer, Cloudflare Zero Trust, or Zscaler is more appropriate. ExpressVPN is primarily suited for straightforward remote access to general internet resources rather than internal corporate systems.
6
What is the best always-on VPN solution? Cisco AnyConnect (now Cisco Secure Client) is the most widely used always-on enterprise VPN, enforcing automatic VPN connection before any network access is allowed. Palo Alto GlobalProtect also offers always-on VPN with pre-logon capability. Microsoft Always On VPN is built into Windows 10/11 for organizations using Active Directory and Microsoft infrastructure.
Always-on VPN means the VPN connection is established automatically when a device starts, before the user logs in, and is enforced at all times — users cannot simply disconnect or bypass the VPN. This differs from a traditional “connect when needed” VPN. The three leading always-on VPN solutions are: Cisco Secure Client (formerly AnyConnect): policy-driven, enforces VPN across wired, wireless, and cellular; widely deployed in large enterprises. Palo Alto GlobalProtect: IPsec/SSL VPN with pre-logon always-on capability and integration with Palo Alto’s NGFW and Prisma Access SASE platform. Microsoft Always On VPN: built into Windows 10/11 Server infrastructure, enforces IKEv2 tunnels via Active Directory policies, ideal for Microsoft-centric organizations. Modern ZTNA solutions like Cloudflare Access and Zscaler Private Access provide an equivalent effect — every request is verified continuously — without the performance bottleneck of traditional always-on tunnel VPNs.
7
What is ZTNA and how is it different from a traditional VPN? Zero Trust Network Access (ZTNA) grants access to specific applications only, verifying every request based on user identity, device health, location, and behavior. Traditional VPN authenticates once and then grants broad network access. ZTNA is defined by NIST SP 800-207 and is the standard now endorsed by NIST, CISA, and major compliance frameworks including GDPR, HIPAA, and PCI DSS 4.0.
The core difference: a traditional VPN creates an encrypted tunnel that puts you “inside the network” — once authenticated, you can reach any resource on that network segment. ZTNA grants access only to the specific application you have been authorized to use, and verifies your identity and device health every time, not just at login. The Zero Trust model was formally defined in NIST Special Publication 800-207, published in 2020, which established Zero Trust Architecture as the recognized standard for enterprise security. ZTNA’s practical advantages: applications are hidden from the public internet (invisible to attackers); lateral movement across the network is blocked by design; compromised credentials give attackers access to one application, not the entire network; compliance with GDPR, HIPAA, PCI DSS 4.0, SOC 2, ISO 27001, DORA, and NIST SP 800-207 is inherent to the ZTNA logging and access model. Organizations migrating from VPN to ZTNA typically report 30–50% cost savings by eliminating VPN hardware, reducing bandwidth, and decreasing management overhead.
8
What is Cisco AnyConnect VPN and is it still the best? Cisco AnyConnect (now rebranded as Cisco Secure Client) is the most widely deployed enterprise VPN globally, offering policy-driven access across wired, wireless, and VPN connections with AES-256 encryption and multi-factor authentication. It remains the gold standard for large enterprises with complex compliance requirements and existing Cisco network infrastructure.
Cisco AnyConnect / Secure Client is a policy-driven VPN tool designed to secure remote workers’ network access from any device, at any time, from any location. It provides posture assessment (checking if devices meet compliance requirements before granting access), seamless roaming across connections, and deep integration with Cisco’s broader security ecosystem (Umbrella, Identity Services Engine, Duo MFA). Cisco Secure Client replaced AnyConnect as the product name in 2023, unifying endpoint security agents. It supports IPSec and SSL/TLS VPN protocols. Gartner Peer Insights notes it as an “excellent solution for those remote users that need simple access to company resources” and rates it highly for integration with Cisco infrastructure. The main limitations are cost (enterprise Cisco licensing is substantial), complexity, and the fact that it is a traditional VPN model, not ZTNA — meaning it grants network access rather than application-specific access.
9
What is a SaaS VPN solution and which is best? A SaaS VPN is a cloud-delivered VPN or ZTNA service with no hardware to buy, install, or maintain. The best SaaS VPN solutions are Cloudflare Zero Trust (free tier for 50 users), NordLayer, Zscaler Private Access, Perimeter 81 (acquired by Check Point), and Tailscale. These scale on demand and integrate with cloud identity providers like Okta, Azure AD, and Google Workspace.
Traditional VPN required purchasing hardware (VPN concentrators, firewalls), on-premises installation, and ongoing maintenance. SaaS VPN solutions eliminate all of that — you subscribe to a cloud service, install a lightweight client on employee devices, and connect. ZTNA solutions with SaaS-based management tools provide significant advantages over traditional on-premises VPN solutions, according to KuppingerCole analysis: they are more flexible, scalable, and integrate with modern cloud identity systems. The best SaaS VPN for different needs: startups and small teams: Cloudflare Zero Trust (free for 50 users) or Tailscale; growing SMBs: NordLayer ($7–$14/user/mo) or Perimeter 81; enterprises: Zscaler Private Access (ZPA), Palo Alto Prisma Access, or Cisco+ Secure Connect (the SaaS version of AnyConnect). All of these eliminate hardware costs and support integration with Single Sign-On (SSO), SCIM user provisioning, and major identity providers.
10
What is team VPN and how does it differ from consumer VPN? Team VPN (also called business VPN or commercial VPN) adds centralized management, dedicated gateways, user provisioning, compliance logging, and SSO integration on top of standard VPN encryption. Consumer VPN protects one person’s internet traffic. Team VPN protects an entire organization’s access to internal systems and enforces corporate security policies across all employees.
The practical differences between a consumer VPN and a team/business VPN are substantial. Consumer VPN (NordVPN, ExpressVPN, ProtonVPN personal): encrypts internet traffic, hides IP address, bypasses geo-restrictions. One account, one or a few devices. No centralized management. Team/Business VPN (NordLayer, Cloudflare Zero Trust, Zscaler, Cisco Secure Client): creates encrypted tunnels to specific corporate resources, not general internet; allows IT administrators to control exactly which employees can access which systems; provides audit logs and compliance reports; integrates with identity providers (Active Directory, Okta, Azure AD); supports device health checks before granting access. Commercial VPN providers offer both models — NordVPN has NordLayer for teams; ExpressVPN has ExpressVPN Teams; ProtonVPN has business plans. The team/business version typically adds: centralized billing, SAML/SSO integration, dedicated IP gateways, 24/7 business support, and compliance-grade logging absent from consumer plans.

🏆 10 Best Enterprise VPN & ZTNA Solutions — Verified Features, Pricing & Contact Info

⚠️ VPN vs. ZTNA — Understanding What You Are Looking At

This guide covers both traditional enterprise VPN products and modern Zero Trust Network Access (ZTNA) solutions. Many vendors now offer both, or have evolved their VPN product into a ZTNA platform. The fundamental security principle is shifting: ZTNA grants access to specific applications per request, while traditional VPN grants broad network access after a single login. Both provide encrypted remote access — ZTNA simply does it with stronger security controls per NIST SP 800-207 standards. For compliance with GDPR, HIPAA, PCI DSS 4.0, and FedRAMP, ZTNA is now the preferred architecture.

📊 Enterprise VPN & ZTNA Market — Key Numbers Verified

📈 ZTNA New Deployments Share

70%+

Gartner’s forecast: by 2025, at least 70% of new remote-access deployments use ZTNA over traditional VPN — up from under 10% in 2021. Over 80% of new ZTNA deployments are now part of SASE or SSE platform deals per UINAT 2026 analysis.

💰 Global VPN Market Size

$44.6B

The global VPN market is valued at $44.6 billion per ExpertInsights, and is predicted to grow to $87.1 billion by 2027. The ZTNA sub-market alone was $2.48 billion in 2025 and is projected to reach $14.74 billion by 2033 at a 25% CAGR.

🚨 VPN Exploit Rate

56%

56% of organizations have been hit via VPN exploits, according to Kitecyber’s cybersecurity analysis. This is the primary driver of ZTNA adoption — traditional VPNs create broad network access that turns a single stolen credential into a major data breach.

📉 Cost Savings: VPN → ZTNA

30–50%

Organizations migrating from VPN to ZTNA typically report 30–50% total cost savings, including elimination of VPN hardware, reduced bandwidth, decreased management overhead, and reduced support tickets per TerraZone 2026 analysis and ZTNA vendor data.

🚨 Three Critical VPN Security Risks Businesses Must Understand in 2026

Traditional VPN grants network-wide access once credentials are compromised. When an attacker steals a username and password for a traditional VPN, they gain access to the entire network segment, not just one application. This lateral movement risk is why 56% of organizations have experienced VPN-based breaches. ZTNA eliminates this by granting access to specific applications only. If credentials are stolen, the attacker can only access what that user was authorized to use — typically one or two applications.
VPN concentrators are public-facing attack targets. Traditional VPN gateways expose public IP addresses to the internet, creating targets for attackers scanning for unpatched firmware, misconfigurations, or known CVEs. In 2025, multiple critical CVEs in widely-deployed enterprise VPN products (including Cisco, Ivanti, and Palo Alto) resulted in mass exploitation before patches could be applied. ZTNA solutions hide application infrastructure completely from the public internet — applications are invisible to anyone not explicitly granted access.
Not all “zero trust” is equal — many products use the label without delivering the architecture. True ZTNA, as defined in NIST SP 800-207, requires continuous verification of every access request, least-privilege access per application, device health assessment, and comprehensive audit logging. Many products use “zero trust” in marketing while still granting broad network access after initial authentication. When evaluating vendors, ask: “Does access occur at the application level or the network level?” Application-level access is true ZTNA; network-level access with better authentication is still effectively a VPN.

❓ Enterprise VPN Questions Answered Plainly

💡 Should My Business Choose a Traditional VPN or Zero Trust Network Access?

The answer depends on your team size, technical capability, compliance requirements, and whether your resources are primarily cloud-based or on-premises. Choose traditional VPN (Cisco Secure Client, GlobalProtect) if: your organization is large with established Cisco or Palo Alto infrastructure; you have dedicated IT/networking staff; you need to connect entire network segments (branch offices) rather than individual users; your applications are legacy on-premises systems that do not support modern identity protocols. Choose ZTNA (Cloudflare Zero Trust, Zscaler, Fortinet, NordLayer) if: most of your applications are SaaS or cloud-based; your workforce is hybrid or remote-first; you are a growing business without legacy VPN infrastructure; you need to demonstrate compliance with GDPR, HIPAA, PCI DSS 4.0, or NIST SP 800-207; you want application-specific access rather than network-wide access; you want to eliminate VPN hardware costs. For small businesses (under 50 people): Cloudflare Zero Trust (free for 50 users) or NordLayer ($7/user/month) provides the best balance of security, usability, and cost. NIST, CISA, and the U.S. Federal Government’s M-22-09 Zero Trust Strategy all formally endorse Zero Trust architecture as the preferred approach for 2025 and beyond.

💡 What Encryption Do Enterprise VPNs Use? What Is AES-256?

AES-256 (Advanced Encryption Standard with 256-bit keys) is the encryption standard used by the U.S. government, military, banks, and every major enterprise VPN provider. It is considered computationally infeasible to brute-force with current and foreseeable computing technology. When a VPN says it uses AES-256, it means your data is scrambled in a way that would require more energy than exists in the known universe to decrypt without the key. Modern enterprise VPNs like ProtonVPN also offer ChaCha20, an equally strong but computationally lighter cipher that performs better on devices without dedicated cryptographic hardware (like mobile phones). The non-negotiable requirements for enterprise VPN encryption are: AES-256 or ChaCha20 encryption; multi-factor authentication (MFA); independently audited no-log policies; and Perfect Forward Secrecy (PFS), which means each session uses a unique encryption key so that compromising one session’s key does not expose past sessions. WireGuard is a modern VPN protocol (not an encryption algorithm itself) that uses ChaCha20 for encryption and delivers significantly faster performance than older IPSec and OpenVPN implementations.

⚠️ What Is the Difference Between a Site-to-Site VPN and a Remote Access VPN?

A remote access VPN connects individual users to a corporate network from their laptops, phones, or other devices. This is what most people think of as a VPN for business — employees working from home connect their devices to the company’s network so they can access internal files, systems, and applications. A site-to-site VPN connects entire networks to each other, typically connecting a branch office network to a main headquarters network over the internet. All devices at the branch office share the VPN tunnel without individual connection setup. Cisco AnyConnect and NordLayer are primarily remote access VPN tools. Cisco Meraki MX and Fortinet FortiGate are commonly used for site-to-site connections. Modern ZTNA solutions like Cloudflare Zero Trust and Zscaler Private Access replace the remote access VPN while Secure SD-WAN solutions replace site-to-site VPNs in cloud-first architectures. Many businesses run both simultaneously during the transition to fully cloud-based infrastructure.

💡 What Compliance Standards Require VPN or Zero Trust Access Controls?

Multiple major compliance frameworks now mandate or strongly recommend Zero Trust access controls: NIST SP 800-207 (2020) formally defined Zero Trust Architecture as the standard for enterprise security and is the foundation that all U.S. government and CISA guidance references. HIPAA (healthcare): requires encryption of all data in transit and access controls limiting employee access to only the data needed for their role. PCI DSS 4.0 (payment card data): mandates network segmentation and access controls that are most efficiently implemented via ZTNA. GDPR (European personal data): requires “appropriate technical measures” for data protection, which regulators increasingly interpret as including Zero Trust access controls. SOC 2 Type II: auditors review access control, encryption, and logging controls that ZTNA platforms provide natively. ISO 27001: requires access control policies that ZTNA fulfills more completely than traditional VPN. U.S. Federal (OMB M-22-09): mandated all federal agencies move to Zero Trust architecture by 2024. For healthcare, financial services, legal, and government contractors, consulting a compliance specialist before choosing your VPN or ZTNA solution is advisable.

💡 My Team Is Not Technical. What Is the Simplest Enterprise VPN to Set Up?

For non-technical teams, ranked from simplest to most complex: 1. Cloudflare Zero Trust — free for up to 50 users, web-based dashboard, connects with Google Workspace or Microsoft 365 login. No hardware, no technical networking knowledge required. Setup for a small team can be completed in under an hour. 2. NordLayer — install the app on employee devices (Windows, Mac, iOS, Android), create accounts in the dashboard, and users connect just like a consumer VPN. The admin panel is clean and well-documented. 3. Tailscale — install the app on devices, sign in with Google or Microsoft accounts, and devices can see each other on a private network automatically. No firewall configuration needed. 4. ExpressVPN Teams — the simplest VPN setup experience, familiar consumer-grade UI, but less granular security control than the above. Avoid traditional enterprise solutions (Cisco AnyConnect, Palo Alto GlobalProtect) for non-technical teams — they require dedicated IT staff for deployment, policy configuration, certificate management, and ongoing maintenance.

✅ Five Steps to Choose the Right Enterprise VPN or ZTNA Solution

Step 1: Determine whether you need traditional VPN or Zero Trust Network Access. If you are a small business with fewer than 50 employees and primarily use cloud-based tools (Google Workspace, Microsoft 365, Salesforce, Slack), a modern ZTNA solution like Cloudflare Zero Trust or NordLayer is simpler, more secure, and often cheaper than traditional VPN. If you have on-premises servers, legacy applications, or complex networking, a traditional VPN may still be necessary as part of a hybrid approach.
Step 2: Identify your compliance requirements before selecting a vendor. If your business handles healthcare data (HIPAA), payment card data (PCI DSS 4.0), European personal data (GDPR), or U.S. federal information (FedRAMP), your VPN or ZTNA solution must support the specific technical controls those frameworks require, including audit logging, access reviews, MFA enforcement, and encryption standards. Request compliance documentation from any vendor you evaluate.
Step 3: Start with a free or trial tier before signing any contract. Cloudflare Zero Trust is completely free for up to 50 users. Tailscale has a free tier for small teams. NordLayer offers a 14-day trial. Most enterprise vendors (Zscaler, Palo Alto, Cisco, Fortinet) provide proof-of-concept testing. Always pilot a solution with a small group of employees before enterprise-wide deployment to catch integration issues and user experience problems early.
Step 4: Verify MFA, SSO, and identity provider integration before committing. Single Sign-On (SSO) integration with your existing identity system (Microsoft Azure AD, Google Workspace, Okta, or Active Directory) is critical for adoption. If employees need a separate VPN login and password, many will find workarounds or leave VPN disconnected. The best enterprise VPN solutions authenticate through your existing identity system, requiring no additional passwords.
Step 5: Plan your endpoint coverage and device management strategy. A VPN is only as secure as the devices connecting to it. Before deploying any VPN or ZTNA solution, inventory every device that will connect (company laptops, personal phones, tablets, contractor devices), determine whether BYOD devices will be allowed, and implement basic device management (MDM) so you can enforce minimum security standards and revoke access for lost or stolen devices. Most enterprise ZTNA solutions include device posture checks — turn them on.
