Next-Gen VPN vs SASE TCO

Inputs & Assumptions

VPN stack vs SASE – TCO model

Compare a legacy VPN + security stack against a SASE-based access architecture across your remote edges, including licenses, infrastructure and operations.

VPN gateway + agents

SASE/ZTNA + cloud SWG

Includes helpdesk “VPN pain” tax

Edges e.g. 200 remote edges

Time horizon (years) 3–7 typical

VPN Stack Model

VPN stack / edge / month ($) gateway + client + SWG, etc.

VPN infra CAPEX total ($) appliances, install

VPN infra OPEX / year ($) support, maintenance

VPN ops FTE count design + operations

Tickets per edge / year (VPN) passwords, drops, reauth

Cost per ticket ($) fully loaded

Ops Cost (Shared)

Ops cost / FTE / year ($) fully loaded engineer

SASE Model

SASE / edge / month ($) SASE + ZTNA bundle

SASE infra OPEX / year ($) if any on-prem

SASE ops FTE count typically lower

Tickets per edge / year (SASE) usually fewer

5-Year TCO Comparison

VPN stack Legacy

$0 / edge / month

SASE Cloud access

$0 / edge / month

Relative 5-Year TCO –

💡

SASE is neutral vs. VPN in this model.

Adjust license, FTE and ticket assumptions to explore upside.
