enhanced.io, the channel-only Open XDR SOCaaS for MSPs
TL;DR
The decision to replace VPN turns on access breadth, device posture, visibility and operational burden, not on a single trigger.
Traditional VPN grants one-time authentication into a broad network. Zero trust grants scoped access to a specific resource, checked continuously.
A phased migration moves high-risk users first: baseline usage, enrol new users, migrate high-risk accounts, validate, then retire legacy access.
Insurers and regulated clients increasingly expect session logs and policy records as evidence, not just a stated access policy.
enhanced.io is a channel-only Open XDR SOCaaS built exclusively for MSPs, with 400+ integrations across endpoint, network, cloud, identity and IoT/OT, correlating access activity across whichever model a client runs.
A practical client workshop agenda closes the piece, for deciding whether to keep, constrain or replace VPN.
A decision tree, not a single trigger
Whether to replace VPN with zero trust access comes down to four factors, assessed together: how broad the access is once someone connects, what condition the connecting device is in, how much visibility the MSP has into what happens after connection, and how much operational burden the current setup already creates.
Recent industry commentary has argued that VPN replacement has moved from a roadmap item to something closer to an urgent operational decision for MSPs. That framing fits what we're seeing in partner conversations. It's less a question of if than a question of which clients move first.
One-time authentication versus resource-scoped access
Traditional VPN authenticates once, at the point of connection, then grants broad access to whatever sits on that network segment. It works, until a stolen credential or a compromised laptop connects and inherits that same broad access with no further checks.
Zero trust access works differently. It scopes access to a specific resource, checks the request against policy every time, and verifies the device's posture continuously rather than once at login. The practical difference is what happens after someone connects. VPN largely stops checking. Zero trust never does.
A phased migration, not a cutover
A wholesale cutover is where most VPN replacements go wrong, because it tries to migrate every user's habits and every application's compatibility on a single date.
Start by baselining current VPN usage: who connects, from where, to what, and how often. Enrol new users directly onto the zero trust platform rather than adding them to the legacy VPN, so the population needing migration only shrinks from here. Move high-risk users next: anyone with administrative access, anyone handling regulated data, anyone who connects from personal or unmanaged devices. Validate that access still works the way each user needs it to, then retire legacy VPN access for that group. Repeat for the next tier down.
This is the same phased approach behind connecting a partner's existing stack into enhanced.io's correlation layer. Nothing gets ripped out on day one. Coverage extends surface by surface while the partner's team confirms nothing has broken along the way.
What insurers and regulated clients want to see
Cyber insurers and regulated clients increasingly ask for evidence, not a policy statement. Session logs showing who accessed what and when. Policy records showing what conditions were checked before access was granted. A documented list of who still has legacy VPN access and why.
An MSP that can produce this on request, rather than describe it in general terms, is the one that keeps the renewal and wins the referral. This is the evidence layer built into enhanced.io's reporting by default, correlated across the full network security stack rather than pulled from a single access log.
It's worth reading this alongside why SASE alone leaves a visibility gap and what to check before deploying SASE, since remote access decisions and SASE decisions tend to land on the same roadmap.
A client workshop agenda
Bring clients into this decision rather than deciding for them. A short workshop works well: review current VPN usage against the baseline, identify the highest-risk user group first, agree what 'done' looks like for that group, and set a review date for the next tier. Keep, constrain or replace should be a decision the client makes with you, not one delivered to them after the fact.
About enhanced.io
enhanced.io is a channel-only Open XDR SOCaaS built exclusively for MSPs, with 400+ integrations across endpoint, network, cloud, identity and IoT/OT. Access activity, whether it comes through legacy VPN or zero trust, gets correlated with everything else in a client's environment, so partners see the full picture rather than an isolated access log. Our guide to SASE and full spectrum security covers how remote access fits into a wider network strategy. If lateral movement risk is part of what's driving this review, get in touch and we'll help you baseline usage before the first workshop.
FAQ
Does every client need to replace VPN immediately?
No. The decision turns on access breadth, device posture, visibility and operational burden for that specific client. Some environments can run VPN safely for longer, provided those four factors are genuinely reviewed rather than assumed.
What's the difference between VPN and zero trust access in practice?
Which users should move to zero trust first?
What evidence do insurers typically ask for around remote access?
Can zero trust and VPN run side by side during migration?
