The old "trust everything inside the network" model is dead. Billow's Zero Trust services help you design and implement a Zero Trust architecture identity-first access, least privilege, microsegmentation and continuous verification so every user, device and request is verified, never assumed.
Zero Trust is a security model that assumes no user, device or request is trustworthy by default — every access attempt is verified, authorized and continuously checked, regardless of where it originates. It replaces the old idea of a trusted internal network with a simple rule: never trust, always verify.
The perimeter model no longer works. With cloud, SaaS and remote work, there is no clean "inside" to trust — attackers who get one foothold move laterally with ease. Zero Trust removes that implicit trust: it verifies identity on every request, grants the least privilege necessary, segments the network so a breach cannot spread, and keeps checking continuously rather than once at login.
Billow designs and implements Zero Trust as a staged program, not a product you buy. We start with the highest-impact controls — strong identity, MFA and least privilege — then layer in microsegmentation, Zero Trust Network Access (ZTNA) and continuous monitoring. The result is a Zero Trust architecture that shrinks your attack surface and contains the damage when something does get through.
Our Zero Trust services cover the whole architecture — every pillar of "never trust, always verify," sequenced so the biggest risks close first.
We map your current trust assumptions and gaps against a Zero Trust model, and build a prioritized, staged roadmap.
Strong authentication and identity are the core of Zero Trust — MFA, SSO and conditional access verify every user on every request.
Access is granted by policy, minimally and just-in-time, so a compromised account can reach almost nothing.
We segment the network so workloads and users are isolated — a breach in one place cannot spread across the estate.
ZTNA replaces flat VPN access with per-app, identity-based access — users reach only what they are allowed to, and apps stay hidden.
Trust is re-evaluated continuously on signals like device health and behavior — not granted once and forgotten.
Every place your systems assume trust is a place an attacker can abuse it. Zero Trust removes those assumptions — verifying continuously, granting the least access, and containing anything that slips through.
Designing as if attackers are already inside means one foothold does not become a full compromise.
Least privilege and segmentation mean a breached account or workload can reach almost nothing.
Zero Trust fits a world with no perimeter — protecting users, SaaS and cloud wherever they are.
Access is re-checked on live signals, so trust is never permanent and risk is caught as it changes.
We implement Zero Trust with the leading identity, access and segmentation platforms — matched to your stack, not forced.

We map where your systems assume trust today and score the gaps against a Zero Trust model.
We design a Zero Trust architecture and staged roadmap — identity, least privilege, segmentation and ZTNA.
We roll out controls in priority order, starting with the highest-impact wins like MFA and least privilege.
Continuous monitoring and policy tuning keep verification live Zero Trust is maintained, not finished.
Zero Trust ties your security controls together. These connect to it most closely.
The full security practice this sits within — endpoint, SIEM & SOAR, cloud security, information protection and more.
Zero Trust extends into the cloud — securing configurations, workloads and access across AWS, Azure and GCP.
Agents need identities and least-privilege access too — IAM is the backbone of controlling what AI can reach.
