Security & Compliance

Secure by Design

All ICPaaS deployments comply with HIPAA, SOC 2, ISO 27001, and TRAI telecom safety protocols.

CyberSecurity Audit

VAPT in CPaaS

Vulnerability Assessment and Penetration Testing (VAPT) in CPaaS (Communications Platform as a Service) is a specialized cybersecurity audit designed to secure cloud-based communication APIs, SDKs, and infrastructure. Because platforms like Twilio, Sinch, or Infobip integrate real-time voice, SMS, video, and chat directly into business applications, they face unique attack surfaces that traditional network testing misses.

Key Attack Surfaces in CPaaS

API Gateways

Vulnerable endpoints, improper authentication, and missing rate-limiting controls.

Webhooks

Insecure callbacks. ICPaaS implements Smart HMAC Webhook Signature Verification and automated IP whitelisting to guarantee callback integrity.

Session Management

Flaws in how real-time communication tokens (like WebRTC or SIP tokens) are generated.

Data in Transit

Unencrypted communication channels allowing eavesdropping or man-in-the-middle attacks.

CPaaS VAPT Methodology

Phase 1

Vulnerability Assessment

Scan API endpoints, check cryptographic configurations

Phase 2

Penetration Testing

Exploit access tokens, bypass rate limits manually

Phase 3

Business Logic Evaluation

Test for toll fraud, SMS pumping, spoofing

1

Information Gathering

Mapping out all public APIs, software development kits (SDKs), documentation, and communication entry points.

2

Vulnerability Assessment

Running automated tools to detect known bugs, open ports, and outdated cryptographic protocols.

3

Penetration Testing (Exploitation)

Manually attacking the system to bypass authorization, hijack active user sessions, or manipulate API parameters.

4

Business Logic Testing

Evaluating how the platform prevents exploits like SMS pumping. ICPaaS uses Smart ML-driven Anti-Toll Fraud algorithms to dynamically intercept and auto-block anomalous traffic spikes.

Top CPaaS Vulnerabilities Exploded During Testing

Toll Fraud & Telephony Denial of Service (TDoS)

Attackers exploit unthrottled API endpoints to generate massive volumes of international premium-rate calls, causing severe financial damage.

SMS OTP Bypass & SMS Pumping

Flaws that allow hackers to guess One-Time Passwords or force the platform to send millions of automated texts to generate artificial traffic revenue.

Broken Object Level Authorization (BOLA)

Manipulating identifiers in API requests (e.g., changing user_id=101 to user_id=102) to view or download other companies' private call logs or chat history.

Caller ID/SMS Spoofing

Simulating trusted alphanumeric sender IDs or phone numbers to conduct highly convincing phishing attacks.

Compliance Drivers

Conducting regular VAPT on CPaaS integrations is mandatory for meeting critical industry benchmarks:

PCI DSS

Required if credit card data or payment authentication passes through voice/SMS APIs.

HIPAA

Mandatory if healthcare providers utilize the platform to transmit patient health records or medical updates.

SOC 2 Type II

Required to prove to corporate clients that communication data is securely processed, confidential, and highly available.
