HITRUST CSF Compliance in the Cloud—How Aviatrix Secures Healthcare Data
How CNSF Protects Cloud Workloads
Cloud attackers don’t rely on a single exploit — they rely on paths.
Once inside, attackers move laterally between workloads, establish command-and-control through egress paths, and exfiltrate data through legitimate cloud services — often before detection tools generate an alert. These paths exist because most security architectures enforce at centralized inspection points, not at every workload. The paths that matter most are the ones that never reach a central firewall.
Aviatrix Cloud Native Security Fabric (CNSF) contains attacks by enforcing policy at every workload communication path — containing blast radius, blocking lateral movement, and cutting off egress before data leaves the environment.
With CNSF, enterprises can:
- Contain attack paths at runtime
Gain visibility into east-west and egress workload communication and apply controls that limit lateral movement, unauthorized egress, and uncontrolled trust expansion.
- Eliminate blind spots in workload-to-workload traffic
Observe traffic across VPCs/VNets, regions, and cloud providers using cloud native telemetry — including paths that posture tools and point controls don’t model.
- Secure modern and AI-driven workloads
Understand how agents, services, and workloads communicate at runtime, and enforce policy to reduce the risk of misuse, over-privileged access, or unintended data flows.
- Apply consistent Zero Trust controls without slowing teams
Enforce segmentation, egress control, and encryption centrally across clouds — without agents, application changes, or developer friction.
See Your Attack Paths. Close the Gaps with CNSF.
Blast radius starts where your enforcement stops.
Most security architectures enforce at centralized inspection points. Attackers move between workloads on paths that never reach those points — building blast radius invisibly until detection tools fire, often too late.
Your assessment delivers:
The Aviatrix Workload Attack Path Assessment (WAPA) analyzes real workload communication using cloud native telemetry to uncover attack paths already present in your environment — and shows how Cloud Native Security Fabric (CNSF) can break those paths with runtime enforcement.
The threat landscape has changed.
Has your question changed with it?
In March 2026, TeamPCP proved that detection-first architectures cannot contain attacks that move through trusted code, not around defenses. Today’s threat actors don’t break in — they log in, blend in, and expand silently. This command center tracks the evolving threat landscape and helps you measure your Blast Radius — the architectural metric that defines resilience in the Containment Era.
This command center tracks 8 active campaigns and measures your Blast Radius: what an attacker can reach once inside your environment.
