Your VPN gives remote users a door to your whole network. Zero Trust gives them a key to one room.
ZTNA replaces broad VPN access with identity-verified, application-specific access. Users reach only what their role requires, from any device, any location. If a credential is stolen, the attacker gets one app, not your network.
Fixed-scope deployment. The fastest path to Zero Trust. Foundation for expanding to full SASE when you are ready.
While your VPN exposes everything
When a remote employee connects via VPN, do they reach specific apps or your entire network?
If a VPN credential is stolen, how much of your infrastructure can an attacker reach?
How long does it take to add or remove a VPN user, and do you always catch leavers in time?
Do contractors and vendors have the same network access as full-time employees?
Is your remote access policy enforced at the application layer, or does it rely on perimeter controls alone?
Could your FortiGate or existing firewall support ZTNA without replacing your current infrastructure?
What We Deliver
Four layers of access control. Zero network exposure.
Each layer addresses a distinct failure mode of traditional VPN access — together they close the exposure gap completely.
Application-Specific Access
Users are authenticated to individual applications — not granted a key to your entire network. Each app is a separate access decision. A compromised credential reaches one destination, not everything behind your perimeter.
Per-application access policies: each app granted independently
No network-level access: users never touch infrastructure they don't need
Role-based application groups: access follows the job, not the person
Instant revocation: access removed per app the moment a role changes
Identity and Device Verification
Every access request is evaluated before any application is reached: who is asking, from what device, from where, and at what risk level. A valid username and password is not enough — context is verified on every attempt.
Identity verification: user authenticated before any app is reached
Device trust: only managed or enrolled devices pass the access check
Location and context evaluation on every request
MFA enforced at the access layer — not bolted on separately
Micro-segmentation and Lateral Movement Prevention
A compromised account cannot move sideways through your environment. Each application is isolated — access to one does not imply access to adjacent systems. Attackers who get in stay contained.
Application isolation: breach of one app cannot propagate to others
East-west movement blocked at the policy layer
Contractor and vendor access scoped separately from employee access
Sensitive systems segmented with additional verification requirements
Continuous Session Monitoring
Access is not a one-time decision at login. Context is re-evaluated continuously throughout each session — if risk increases mid-session, access is challenged or revoked automatically. Full audit trail maintained per user, per application.
Continuous re-evaluation: risk checked throughout the session, not just at login
Automatic session termination if device or location context changes
Full access log: who accessed what, from where, and when
Audit-ready reporting for insurance and compliance reviews
ZTNA vs VPN
Same remote access problem. Completely different exposure.
VPNs were built for a world where everyone worked from the office. ZTNA was built for the world you actually operate in.
VPN today
Remote user reaches entire network segment on connection
With ZTNA
Remote user reaches only the apps their role requires
VPN today
Stolen credential gives attacker full network access
With ZTNA
Stolen credential reaches one app — nothing else
VPN today
New user provisioned manually, often days late
With ZTNA
Access provisioned immediately on role assignment
VPN today
Contractor access identical to employee access
With ZTNA
Contractor access scoped to specific tools only
VPN today
No visibility into what was accessed or when
With ZTNA
Full access log per user, per application, per session
VPN today
Removing a leaver requires hunting down every VPN config
With ZTNA
Access revoked across all apps in one action
How It Works
Live in 2 to 4 weeks. VPN decommissioned. No disruption.
Your VPN stays live throughout the migration. Nothing is removed until the replacement is fully validated.
Discovery and App Inventory
We map every application your workforce accesses remotely: internal tools, cloud apps, and sensitive systems. Access requirements documented per role before any policy is written.
Application inventory completed
Role-to-app access matrix defined
VPN dependency mapped
Policy Design
Access policies written per application and per role. Device trust requirements defined. Contractor and vendor access scoped separately. Policies reviewed and signed off before deployment begins.
Per-app access policies documented
Device trust requirements confirmed
Contractor access policies defined
Deployment and VPN Cutover
ZTNA deployed alongside your existing VPN — users migrated in phases so no one loses access during cutover. VPN decommissioned only after full validation. Zero disruption to the business.

Ongoing Management and Access Governance
Access policies updated as roles, staff, and applications change. New apps onboarded. Leavers revoked within the hour. Access reviews run on a defined cadence. Audit trail maintained continuously.

Who This Is For
Real VPN problems. Real situations.
If your remote access is built on a VPN, every one of these scenarios applies to you.
Remote Workforce with Legacy VPN
Fully remote team on a slow, unreliable VPN — IT managing client configs, staff complaining about connectivity, and every remote user able to reach the entire internal network.
VPN replaced with application-specific access. Staff reach their apps directly from any device without a VPN client. IT stops managing VPN configs. Network exposure eliminated.
Contractors and Vendors
External contractors given the same VPN access as full-time employees to reach one internal tool — with no easy way to scope or time-limit their access.
Contractors granted access to specific applications only, with time-limited sessions and device verification. Employee network stays out of reach.
Post-Merger Access Control
Two companies merged with separate networks and no clean way to give employees of the acquired company access to the right tools without exposing everything.
ZTNA deployed as the access layer between the two environments. Each group reaches only what the integration plan requires. No network peering, no broad exposure.
Cyber Insurance Compliance
Insurance renewal requiring documented least-privilege access controls and evidence that remote users cannot reach more than their role requires.
ZTNA policies produce the access log and least-privilege evidence the insurer requires. Renewal documentation produced from existing access records.
