1) Executive Summary
Enterprise access in 2025 blends traditional VPN with Zero Trust Network Access (ZTNA) and SASE (secure access service edge). Your winning setup should deliver strong identity, least-privilege access, fast throughput worldwide, and provable compliance. This guide shows you how to evaluate vendors with a practical, vendor-neutral scorecard—so you can build a shortlist and run a clean proof of concept (POC).
2) What Is an Enterprise VPN in 2025 (and When You Need SASE/ZTNA)
- Enterprise VPN: Encrypted tunnels (IKEv2/IPsec, WireGuard, TLS-based) from users or sites to corporate resources. Still vital for legacy networks, server-to-server links, and full-tunnel scenarios.
- ZTNA: App-level access based on identity and device posture—no flat network exposure, fewer lateral-movement risks.
- SASE: Converges networking + security (SWG, CASB, DLP, firewall-as-a-service, SD-WAN) with global PoPs for performance and consistent policy.
When to choose what:
- Heavy legacy, site-to-site, or self-hosted apps → VPN + gradual ZTNA overlay.
- Modern SaaS mix, remote-first teams, granular access → ZTNA-first or SASE with ZTNA module.
- M&A or multi-cloud sprawl → SASE gives unified control plane and global acceleration.
3) Key Features That Matter (Security, Performance, Compliance)
Security & Identity
- MFA/Phishing-resistant auth (FIDO2/WebAuthn), SSO (SAML/OIDC), just-in-time access.
- Device posture: OS version, disk encryption, EDR presence, jailbreak/root checks.
- Policy granularity: per-app, per-group, time-bound, geofence; micro-segmentation for east-west control.
- Key management & crypto: TLS 1.3, modern cipher suites, certificate pinning, perfect forward secrecy.
Performance & Reliability
- Global PoPs with smart routing and Anycast.
- Protocol agility (WireGuard/UDP, TLS fallback).
- Split tunneling and local breakout for SaaS.
- Autoscaling gateways; high availability (multi-region).
Monitoring & SOC Visibility
- Rich logs (auth, policy, posture, DNS), SIEM integrations (Syslog, Splunk, Datadog).
- Real-time analytics: latency, loss, throughput; per-user and per-app views.
Compliance & Trust
- Audits: SOC 2 Type II, ISO 27001; pen test cadence; SBOM transparency.
- Data residency & privacy controls (regional PoPs, lawful data handling).
- Incident response: SLAs, RTO/RPO, breach disclosure procedures.
4) Pricing Models Explained (Per-User, Gateways, Bandwidth)
- Per-user (tiered): Common for ZTNA/SASE; includes core features with add-ons (DLP/CASB/secure web gateway). Predictable for remote-first teams.
- Per-gateway/connector: Used for self-hosted or hybrid; you pay for appliances/instances.
- Bandwidth-based: Suitable for site-to-site or high-throughput workloads; watch for egress fees.
- Support tiers: Standard vs. premium (24×7, TAM, faster SLAs).
Tip: Model your TCO over 36 months (licenses + infra + ops + support).
5) Deployment Architectures (Cloud, On-Prem, Hybrid)
- Cloud-native: Quickest to deploy; minimal hardware; ideal for distributed workforce.
- On-prem: For tight data controls or air-gapped segments; requires capacity planning and HA pairs.
- Hybrid: Most common—cloud control plane, lightweight connectors close to apps, plus on-prem gateways for legacy.
6) Evaluation Framework (Scorecard & Weights)
Use this to shortlist vendors (total 100):
| Pillar | Weight | What to Check |
|---|---|---|
| Security & Identity | 30 | FIDO2, SSO breadth, posture checks, micro-segmentation, modern crypto |
| Performance | 20 | Global PoPs, WireGuard/TLS agility, throughput, latency SLOs |
| Features | 15 | Per-app access, DNS protection, SWG, DLP/CASB options |
| Visibility | 10 | SIEM export, APIs, live analytics, alerting |
| Compliance/Trust | 10 | SOC2, ISO, data residency, pen tests |
| Pricing/TCO | 10 | 36-mo cost, support tiers, overage risks |
| Ease of Deploy/Operate | 5 | Time-to-value, migration aid, documentation |
Assign 1–5 per cell and multiply by weight.

8) RFP/RFI Question Bank (Copy & Use)
- Identity & MFA: Do you support FIDO2/WebAuthn with passkeys? Any conditional access policies by risk score or device posture?
- Device Posture: Which EDRs and OS signals are evaluated? Can we define custom checks (e.g., registry keys, daemon presence)?
- Policies: How granular are app-level rules? Do you provide time-limited or ticket-bound access?
- Protocols & Performance: Which protocols are supported? How do you mitigate packet loss and optimize latency across regions?
- Visibility: What logs and metrics are exported to SIEM? Do you offer a real-time API for session events?
- Compliance: Provide latest SOC 2 Type II, ISO 27001 scope, and pen-test summary.
- Data Handling: Data residency options? PII minimization? Retention controls?
- SASE Modules: SWG/DLP/CASB availability and how policies are unified.
- Support & SLAs: Response times by severity; premium support pricing; incident comms process.
- Pricing & TCO: Licensing details, overage triggers, multi-year discounts, migration assistance.
9) Rollout Plan: 30–60–90 Days
Days 1–30 (Plan & POC):
- Map apps and user groups; pick 2–3 vendors; run a POC with 50–100 users in 3 regions.
- Validate auth flows, device posture, and performance (latency < 120 ms for most users).
- Document policies (per-app) and emergency break-glass access.
Days 31–60 (Pilot):
- Expand to 25–35% of workforce; integrate SIEM; tune policies.
- Train IT/helpdesk; create self-service docs and quick-start videos.
Days 61–90 (Scale):
- Full rollout region-by-region; set SLOs (availability, latency, incident MTTR).
- Quarterly posture reviews; enable SWG/DLP where needed.
10) Optimization & Ongoing Operations
- KPIs: Auth success rate, median RTT/throughput, ticket volume, policy exceptions.
- Change control: Stage new policies; use canary groups; maintain rollback plans.
- Security hygiene: Rotate keys/certs, review admin roles, quarterly access recertification.
- Cost control: Right-size licenses; watch bandwidth spikes; revisit multi-year pricing.
11) FAQs
Q1: Is ZTNA replacing VPNs entirely?
A: Not for every case. ZTNA is ideal for app-level access, but site-to-site links, legacy protocols, and full-tunnel scenarios still need VPNs. Many organizations run hybrid.
Q2: What protocol should we prefer?
A: Choose vendors that support WireGuard or modern TLS tunnels with fallback. Protocol agility helps across networks and geographies.
Q3: How do we measure user experience?
A: Track end-to-end latency, packet loss, and login success rates per region. Ask vendors for synthetic monitoring and client telemetry.
Q4: How do we prove compliance?
A: Request current SOC2/ISO reports, pen-test summaries, data-flow docs, and evidence of incident response drills.
Q5: What’s the typical price range?
A: Varies by features and scale. Expect per-user monthly tiers for ZTNA/SASE and possible gateway or bandwidth costs for hybrid/site-to-site.
