VOIP Security Assessment Services
Secure your business communications from cyberattackers with Quantumbastions VoIP security assessment services offering a unique blend of industry-leading expertise and advanced technologies.
VoIP penetration testing is a type of penetration testing conducted on a company’s VoIP infrastructure. Pen testers simulate a realistic-looking cyberattack to find vulnerabilities and risks in VoIP systems and services and provide recommendation plans to remediate the risks.
A professional engaged in a phone conversation at his desk appears unaware of the oversized digital "eyes" surrounding him—symbolizing surveillance, eavesdropping, and data interception risks in unsecured VoIP communications. The image creatively illustrates the hidden vulnerabilities that can exist in VoIP systems, where sensitive voice data may be monitored, recorded, or hijacked if proper security measures aren’t in place. This visual metaphor powerfully conveys the need for VoIP Security Assessment Services—to protect your calls, safeguard your data, and ensure your conversations remain truly private.
Voice over IP (VoIP) has transformed the way organizations communicate—enabling cost-effective, scalable, and flexible communication across global teams. However, with this advancement comes increased security risk. VoIP systems, like any other IP-based service, are vulnerable to a wide range of cyber threats including eavesdropping, call hijacking, denial of service (DoS) attacks, toll fraud, and unauthorized access.
Our VoIP Security Assessment Services are specifically designed to evaluate the confidentiality, integrity, and availability of your VoIP infrastructure. Whether you're using SIP-based communication systems, PBX solutions, or hosted VoIP services, we help ensure that your voice traffic is secure, reliable, and compliant.
Infrastructure & Architecture Review:
Analyzing your VoIP environment—IP PBX, gateways, routers, firewalls, and endpoints—to identify vulnerabilities in network design, device configuration, and segmentation.
SIP Traffic & Protocol Analysis:
Reviewing how Session Initiation Protocol (SIP) is implemented to detect flaws like weak authentication, unsecured channels, and exposure to SIP scanning or fuzzing attacks.
Call Interception & Eavesdropping Checks:
Testing the ability of attackers to intercept audio streams or signaling data using techniques such as ARP spoofing, RTP sniffing, or man-in-the-middle (MITM) attacks.
Authentication & Access Control Validation:
Assessing the strength of user/device authentication, directory services, and access policies to prevent impersonation and unauthorized use.
DoS & Resource Exhaustion Testing:
Simulating denial-of-service attempts that could overload your VoIP systems, disrupt call quality, or render services unavailable.
Toll Fraud & Call Pattern Analysis:
Detecting anomalies in call behavior that could indicate fraud or abuse—such as international call abuse, premium-rate fraud, or internal compromise.
Encryption & Secure Media Review:
Evaluating the implementation of encryption protocols such as SRTP and TLS to protect voice data in transit.
Compliance Assessment:
Ensuring your VoIP setup adheres to regulatory standards such as GDPR, HIPAA, PCI-DSS, and ISO 27001 for secure communication.
Prevent voice eavesdropping and data leakage
Avoid service disruption and reputational damage
Detect and stop fraud before financial loss occurs
