Then verify identity and device controls, segmentation, cryptography, patching, capacity under your real workload, resilience, logging, and operational fit. A VPN encrypts traffic in transit; it does not, by itself, make a device trustworthy or prevent an authorized user from reaching too much of the network. Compare VPN with ZTNA or SASE when application-level access to distributed resources may fit better.
Start with the access model, not the appliance
Inventory the people and systems that need remote access before comparing products. Include employees, administrators, contractors, partners, managed and unmanaged devices, locations, applications, and any legacy protocols that affect connectivity. For each user group, record the resources and services it actually needs.
A traditional VPN is a candidate when users need network-level connectivity or applications depend on legacy network behavior. If most users need only specific applications—especially across on-premises and multiple cloud environments—evaluate ZTNA or SASE alongside VPN. NIST SP 800-215 discusses VPN, ZTNA, SASE, and other enterprise-network capabilities; NIST SP 1800-35 describes zero-trust implementations for distributed resources and hybrid workforces. Neither source establishes that every organization should replace its VPN.
Keep the distinction clear: a tunnel is a transport and access mechanism, not a complete authorization strategy. NSA and CISA describe VPN servers as entry points into protected networks and attractive targets. A compromised or misconfigured gateway can therefore put more than the gateway itself at risk.

What to require from an enterprise VPN appliance
Identity and device posture
Confirm integration with your identity provider and the MFA methods your organization requires. Check whether policy can map identity groups and roles to access rules, whether device or certificate identity is supported where needed, and how quickly sessions can be revoked after a user loses authorization.
Define the response to a noncompliant endpoint: deny access, allow only remediation services, or apply another documented restricted state. CISA’s July 2025 TIC remote-user guidance recommends checking endpoint compliance before full-featured VPN access and allowing only authorized services through the tunnel.
Least privilege and segmentation
Require policy controls that limit access by user or group, destination, service, and administrative zone. Separate privileged access from ordinary employee access, and constrain third-party users to explicitly approved systems rather than a broad internal subnet. Verify that remote-access segments are isolated from unrelated internal networks.

Test denied access as deliberately as successful logins: a valid account should not imply permission to reach every internal destination. CISA’s June 2024 joint network-access guidance highlights risks from broad access, misconfiguration, vulnerabilities, and third-party devices, and emphasizes least privilege and segmentation.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Exposure, administration, and cryptography
Document every internet-facing interface, protocol, port, and enabled feature. Require a management plane that can be isolated and restricted, secure configuration defaults, and a way to disable services and algorithms the organization does not use. Specify the cryptographic requirements the product must meet, then verify its actual supported configuration rather than relying on a general claim of “strong encryption.”
CISA hardening guidance recommends minimizing external exposure and exposed ports, using strong cryptography, and disabling unused VPN features and algorithms. Hardware enforcement may be worth evaluating for some environments, but hardware alone does not secure a gateway: configuration, patching, restricted administration, and monitoring still matter.

Patchability and lifecycle
Ask for supported software versions, security-advisory delivery, emergency update procedures, maintenance-window requirements, rollback options, configuration backup and recovery steps, and end-of-support dates. Establish who in your organization can apply urgent updates and how the gateway will be monitored for anomalous behavior. NSA and CISA recommend prompt patches and updates; CISA hardening guidance also calls for baselining normal network behavior and alerting on anomalies.
Capacity, availability, and recovery
Size the deployment around measured demand, not a headline throughput number. Estimate concurrent sessions, connection-establishment peaks, traffic mix, regional distribution, application latency needs, and growth headroom. Ask vendors for performance data with the security features and policies you intend to enable, then validate it with representative traffic in a proof of concept.
Specify availability targets and test what happens to active sessions and new connections when a node or site fails. Confirm failover behavior, recovery time, configuration restoration, and any regional or data-location constraints. The official guidance cited here does not compare current models or establish a universal capacity figure, so no vendor’s headline specification should be treated as your expected real-world capacity.

Logs and operational fit
Check that the gateway can send identity, device, policy, tunnel, administrative, and security events to your SIEM in a usable format. Verify timestamp reliability, time synchronization, encrypted remote-log transport, retention, and alerts for events your operations team can act on. CISA recommends encrypted transport for remote logging and monitoring against a baseline of normal network behavior.
Also assess how the appliance fits your existing identity, endpoint, firewall, network, and SIEM tools. Include staff expertise, upgrade complexity, support arrangements, redundancy, subscriptions, client licensing, migration effort, and ongoing operational work in the cost comparison.
Validation and compliance scope
If a government, defense, or regulated requirement applies, map it to the exact product version, cryptographic module, and required control. NSA and CISA point readers to NIAP product listings for applicable contexts; a listing is not proof that every enterprise needs that product or that every organizational requirement is met. Confirm the current authoritative listing and certificate scope before purchase.

Run a proof of concept against real failure cases
Use representative applications, policies, endpoints, and traffic—not only a successful login demonstration. Define pass/fail criteria before testing and record results for each candidate.
- Test peak concurrent demand and connection bursts with the intended security features enabled; measure application responsiveness and throughput.
- Fail a node or site and observe new connections, active sessions, and recovery behavior.
- Attempt access from a noncompliant device and verify the expected denial or restricted remediation path.
- Use a third-party account to test that only approved destinations and services are reachable; also test explicit denial of unrelated internal resources.
- Test MFA, group or role changes, and session revocation, including how quickly removed access takes effect.
- Confirm that identity, device, policy, tunnel, administrative, and security events reach the SIEM with usable timestamps.
- Walk through an emergency update, configuration backup, rollback, and recovery using the proposed operating process.
