InstaSafe Zero Trust Network Access
Zero trust for the access that isn’t a web app — InstaSafe ZTNA applies verify-first, least-privilege, dark-by-default access at the IP layer for thick-client, legacy and device use cases, alongside ZTAA.
How it’s rated
Full scoreboard ↓Quick answer
InstaSafe Zero Trust Network Access (ZTNA) applies zero trust at the IP layer — the complement to InstaSafe's app-layer ZTAA, for the use cases app-layer access can't reach. Some access needs simply aren't web/cloud apps: thick-client applications, legacy systems, and devices or applications that must be reached at the IP level rather than through a browser. InstaSafe ZTNA extends the same verify-first, least-privilege, dark-by-default model to those cases — a client establishes a verified, encrypted tunnel to a specific device or application at the IP layer, only after identity and device posture are confirmed, with no broad network access granted. It shares the SDP foundation, the MFA/SSO/SAML identity layer, and the same central console as the rest of the portfolio. So where ZTAA secures your browser-based and cloud apps, ZTNA secures the thick-client and IP-level access alongside it — and together, under the unified Secure Access layer, they cover the whole access surface. For organisations with legacy thick-client applications or device-level access needs that still deserve zero trust, ZTNA is the IP-layer answer, from an India-built vendor.

Understand IP-layer zero trust before you buy it
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is ZTNA (here)?
Zero Trust Network Access at the IP layer — InstaSafe's complement to app-layer ZTAA, for thick-client, legacy and device/IP-level access.
Same verify-first, least-privilege, dark-by-default model — just at the layer app-access can't reach.
Legacy VPN vs IP-layer zero trust — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | VPN for legacy/device (broad) | ZTNA (IP-layer, verify-first) |
|---|---|---|
| Thick-client access | Left on the VPN | IP-layer zero trust |
| The layer | App-layer only (gap) | IP-layer covered too |
| Access model | Broad VPN for legacy | Verified tunnel, one resource |
| Resource visibility | Exposed | Dark by default |
| Least privilege | Network-wide | One resource, IP-layer |
| The model | Two different worlds | One model across both layers |
| Legacy systems | Quietly exposed | Under zero trust, no rewrite |
| Audit | Thin | Full logging, both layers |
Pairs with ZTAA for the whole surface — for global scale, compare Zscaler; for a SASE platform, Palo Alto (hub live).
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
SDP Client
The client establishes a verified, encrypted tunnel — identity and device proven before any IP-level access is possible.
IP-Layer Tunnel
A secure tunnel to a specific device or application at the IP layer — for the thick-client and device use cases app-layer access can't cover.
SDP Gateway
Enforces the dark-by-default, verify-first model at the IP layer — no broad network access, only the specific resource granted.
Shared Identity
The same identity and MFA layer as ZTAA — one verification model across app-layer and IP-layer access.
Central Console
Managed from the same console as ZTAA and the portfolio — one policy and one audit trail across the whole access surface.
One agent on every machine, one console over all of them — modules attach without a second operational world.
Twelve capabilities. IP-layer, verify-first.
InstaSafe ZTNA brings zero trust to the thick-client and IP-level access app-layer ZTAA can't reach — same model, one console.
IP-Layer Access
Zero-trust access at the IP layer — for the thick-client and device use cases browser-based app access can't reach.
Thick-Client Support
Secures legacy thick-client applications under zero trust — the apps that aren't web or cloud.
Device-Level Access
Extends secure access to devices and applications at the IP level — verified, least-privilege.
Least-Privilege
Access to a specific resource, not the network — the same least-privilege model as ZTAA, at the IP layer.
Dark by Default
Resources stay invisible until access is verified and granted — SDP applied at the IP layer.
Encrypted Tunnel
A verified, encrypted tunnel to the specific resource — no broad network exposure.
Multi-Factor Auth
The same MFA/SSO/SAML identity layer as the rest of the portfolio — verify-first everywhere.
Device Posture
Device health checked before access — access earned by a healthy device, not just a credential.
Pairs with ZTAA
App-layer (ZTAA) + IP-layer (ZTNA) together cover the whole access surface, under one Secure Access layer.
Central Console
Managed from the same console as ZTAA — one policy, one audit trail across both layers.
Logging & Reporting
The same powerful logging and reporting engine — a complete IP-layer access audit trail.
India-Built
Local vendor, local support and data-residency alignment — the homegrown advantage.

Here’s what genuinely sets InstaSafe ZTNA apart from the alternatives.
Not everything is a web app
Zero-trust app access (ZTAA) is perfect for browser-based and cloud applications — but real estates also have thick-client applications, legacy systems and device/IP-level access needs that can't be reached through a browser tunnel. Those still deserve zero trust. InstaSafe ZTNA extends the same verify-first, least-privilege, dark-by-default model to the IP layer, so the parts of your estate that aren't web apps aren't left on the old VPN.
IP-layer zero trust, not a VPN
The temptation for thick-client and device access is to fall back on the VPN — broad, exposed, risky. ZTNA gives you IP-layer access that's still zero trust: a verified, encrypted tunnel to one specific resource, dark by default, least-privilege, with no broad network access. So even the harder-to-cover cases get the modern model, not the legacy one.
One model, both layers
ZTNA shares the SDP foundation, the MFA/SSO/SAML identity layer and the central console with ZTAA. So you don't run two different security models — you apply one verify-first, least-privilege, dark-by-default model across both app-layer and IP-layer access, with one policy and one audit trail. Consistency is a security property, and this delivers it.
Together, the whole access surface
ZTAA (app layer) and ZTNA (IP layer) together, under the unified Secure Access layer, cover the entire access surface — web apps, cloud apps, thick clients, legacy systems, devices. Most real organisations need both, and having them from one vendor under one console means no gaps and no second security model to run. It's complete zero-trust access, not half.
Legacy systems, finally covered
Older thick-client and legacy applications are often the hardest to secure and the most quietly exposed — exactly the systems left on a broad VPN because ‘there's no other way.’ ZTNA is the other way: it brings those legacy and device-level access needs under zero trust without rewriting the applications, so your oldest access paths stop being your weakest.
India-built, locally supported
Like the rest of the portfolio, ZTNA comes from a homegrown vendor with local support, data-residency alignment and India-market pricing — the local-fit advantages that matter for Indian enterprises and public-sector bodies. TechBag keeps the whole relationship local, from PoC to renewal.

Quick poll — what’s driving your evaluation?
Talk to an advisor“ZTAA handled our web apps, but our thick-client legacy systems needed IP-layer access — ZTNA covered exactly those, under the same zero-trust model. The whole surface, not half.”
“We stopped falling back on the VPN for device-level access — ZTNA gave us a verified, dark-by-default tunnel to one resource. Even the hard cases are zero trust now.”
“One model, one console across app-layer and IP-layer access. We don't run two security worlds — one policy, one audit trail. Consistency is the win.”
“Our oldest thick-client systems were quietly on a broad VPN because ‘there was no other way.’ ZTNA was the other way — no app rewrite needed.”
“Same MFA/SSO/SAML identity layer as ZTAA — verify-first at the IP layer too. It just fit into what we already had.”
“For our India-centric estate, having both layers from one local vendor with local support sealed it. TechBag kept it all local.”
“Least-privilege at the IP layer meant device access reached one resource, not the network. The lateral-movement risk on our legacy paths is gone.”
“ZTAA + ZTNA together finally covered every access path — web, cloud, thick-client, device. No gaps, no second tool.”

What does legacy VPN access cost you?
Drag the sliders (count users; IT-hour cost as loaded security rate). Estimates assume ~1 hour per user per year of legacy/device-access risk on the VPN, with ~60% removed by IP-layer zero trust — the avoided-breach value from dark-by-default, least-privilege access on your oldest paths is the larger unpriced win. Illustrative.
