Continuous Contextual Application Security Trust Layer™

Securing Every
Subscriber Workflow
Before It Ships

In modern telecom and subscription platforms, every subscriber action is an API.
Apiezy validates provisioning workflows, billing integrity, wallet credits, and partner trust boundaries — across distributed services — before production.

SCROLL TO EXPLORE
In Modern Telecom & Subscription

Every Subscriber
Action is an API

SIM / eSIM provisioning is an API
Plan activation, upgrades & downgrades are APIs
Top-ups & wallet credits are APIs
Billing & invoicing are APIs
Device binding & identity verification are APIs
Partner integrations (payment gateways, MVNO, roaming, KYC) are APIs
The Core Risk

Most High-Impact Abuse Is Not Injection-Based

Workflow Bypass in ProvisioningActivation endpoints reached without KYC, OTP, or payment validation
Replay & Idempotency GapsDuplicate callbacks inflate wallet credits causing revenue loss
Cross-Subscriber Data ExposureIdentifier modification accesses other subscribers' invoices and SIM status
Billing & Entitlement State MismatchBilling and provisioning systems drift out of sync across services
Real-World Failure Patterns

07 Attack Vectors
Apiezy Eliminates

01
Workflow Bypass

SIM / eSIM Provisioning Workflow Bypass

Apiezy Prevention
  • Models provisioning state machine end-to-end
  • Attempts out-of-order API execution
  • Validates KYC / OTP / payment enforcement
  • Tests activation preconditions across services
Unauthorized SIM activation paths detected before release
02
Replay

Top-Up / Wallet Credit Duplication (Replay & Concurrency)

Apiezy Prevention
  • Simulates duplicate payment callbacks
  • Tests idempotency enforcement on credit grants
  • Performs concurrent credit attempt scenarios
  • Validates balance locking integrity
Duplicate credit vulnerabilities eliminated before production
03
Plan Abuse

Plan Upgrade / Downgrade Abuse

Apiezy Prevention
  • Simulates upgrade → usage → downgrade sequences
  • Validates proration and cooldown enforcement
  • Tests billing and entitlement synchronization
  • Detects state drift across services
Plan abuse and "benefits farming" detected in staging
04
BOLA/IDOR

Cross-Subscriber Access (BOLA / IDOR)

Apiezy Prevention
  • Generates cross-identity substitution tests
  • Validates object ownership enforcement
  • Tests tenant and role boundaries
  • Flags endpoints that authenticate but don't authorize
Subscriber data exposure prevented pre-release
05
Partner Risk

Partner Webhook Misrouting (Payments / MVNO / Roaming)

Apiezy Prevention
  • Simulates replayed partner events
  • Tests subscriber mapping integrity
  • Validates idempotency enforcement per partner
  • Detects cross-tenant routing issues
Partner misrouting vulnerabilities caught before deployment
06
Identity

Device Binding & SIM Swap Control Gaps

Apiezy Prevention
  • Models identity change workflows end-to-end
  • Attempts bypass of step-up verification
  • Validates MFA enforcement across all entry points
  • Detects missing preconditions in swap flows
SIM swap and device takeover risks reduced before production
07
State Drift

Billing & Entitlement State Drift

Apiezy Prevention
  • Validates billing → entitlement → provisioning invariants
  • Tests cross-service synchronization
  • Detects inconsistent state transitions
  • Flags logic drift across releases
Billing and entitlement consistency enforced pre-release
Capability Gap Analysis

Why Traditional Tools Miss
What Apiezy Catches

SAST

Identifies static code patterns and syntax vulnerabilities at the source level.

Cannot validate runtime provisioning sequencing or billing state correctness

DAST

Probes endpoints for known injection and exposure patterns.

Requires manual scripting for multi-step subscriber and billing workflow simulation

Runtime API Security

Detects anomalies and monitors live API traffic patterns.

Detects only after production exposure — subscriber data and revenue already at risk

Observability / APM

Shows performance, traces, and service health across systems.

Shows symptoms and latency — not billing integrity or entitlement exploitability

Core Capabilities

What Makes Apiezy
Fundamentally Different

A billing and provisioning trust enforcement engine — not a vulnerability scanner.

Provisioning Workflow State ModelingEnd-to-end SIM, plan, and activation flow simulation with precondition enforcement
Replay & Idempotency EnforcementWallet credit and top-up correctness under duplicate callbacks and concurrency
Cross-Subscriber Identity SubstitutionSystematic BOLA/IDOR detection across all subscriber and role combinations
Billing & Entitlement Invariant TestingCross-service consistency validated across billing, entitlement, and provisioning
Partner Webhook Trust ValidationMVNO, payment gateway, and roaming partner event routing integrity tested
CI/CD Pre-Production EnforcementAutomated trust grading integrated directly into your release pipeline
SIM Swap & Identity Workflow TestingMFA and step-up enforcement tested across all identity change entry points
Shadow & Debug Endpoint DiscoveryAdmin and test endpoints discovered and access-tested continuously
Release-Level Trust Regression AnalysisBilling and authorization behavior compared build-to-build to catch drift early
Business Impact

Built for Every
Telecom Decision-Maker

For CTO
Reduce provisioning and billing logic failures across distributed services
Increase secure release velocity without slowing CI/CD pipelines
Catch state drift and regression across subscriber workflows build-to-build
For Security Leadership
Prevent subscriber fraud aligned with real-world attack techniques
Reduce replay, BOLA, and authorization abuse surface systematically

Reduce subscriber data breach risk and associated churn
Lower reconciliation and incident response costs from partner errors
Executive Summary

In telecom and subscription platforms, security is not only about preventing malicious input — it's about ensuring billing, provisioning, identity, and entitlement workflows behave securely across distributed services — before production.
