Call verification, often referred to as call authentication, has become an essential technology for businesses and call centers as they navigate an increasingly challenging communication landscape. Attackers and scammers frequently exploit phone communications to carry out malicious activities like spoofing, vishing, fraud, and other criminal pursuits. These attacks target both customers and organizations, leading to significant financial losses, data breaches, and damage to business reputations. With the Federal Trade Commission reporting that most fraud now occurs over the phone rather than email, the need for robust call verification solutions has never been greater.
What Is Call Verification?
Call verification is the process of ensuring that phone calls originate from legitimate sources and that the caller is who they say they are. By confirming the authenticity of calls in real time, businesses and call centers can protect sensitive information, maintain secure communication, and build trust with their customers.
Call center authentication and verification technologies analyze multiple factors, verifying a caller's legitimacy using both passive and active verification strategies. Passive verification happens in the background, using tools like voice authentication or behavioral analytics to validate caller information without direct interaction. Active verification, on the other hand, requires callers to take specific actions, like providing a one-time password (OTP) or answering security questions.
Why Call Verification Matters
As call centers play a critical role in connecting with customers, they manage a great deal of sensitive customer information. From financial records to personal data, the information handled by agents makes call centers attractive targets for fraudsters. These attackers often use tactics like impersonation and manipulation to trick agents into granting access to accounts or disclosing sensitive details. Such attacks can compromise security, weaken customer trust, and cause severe financial and reputational damage.
Despite these risks, many organizations fail to adequately protect their voice systems, focusing instead on cybersecurity investments for data networks. Call verification software closes this security gap by verifying the authenticity of calls and blocking fraudulent activity before it reaches agents. This helps safeguard operations, protect sensitive data, and restore trust in phone communication.
Key Benefits of Call Verification
Call verification technologies help businesses and their call centers to:
-
Prevent Fraud Call verification software is a powerful tool for stopping spoofing, phishing, and other fraudulent activities. By verifying the authenticity of calls, verification ensures that only legitimate callers can connect with agents or access sensitive systems, preventing financial losses, identity theft, and other harmful consequences of call center fraud.
-
Protect Sensitive Data One of the most critical functions of call verification software is safeguarding sensitive information—from customer account details to financial records and confidential business data. Verification prevents unauthorized access by ensuring that calls and callers are verified before information is shared. This added layer of protection is especially important for industries like finance, healthcare, and retail, where privacy and security are top priorities.
-
Boost Customer Trust Customers are more likely to engage with businesses they trust to protect their information. Call verification software demonstrates a company’s commitment to secure communication by preventing fraud and ensuring safe interactions. This builds confidence in the brand, fosters stronger relationships, and encourages long-term customer loyalty.
-
Improve Efficiency Manual verification processes, like asking repetitive security questions, take time and can frustrate both customers and agents. Call verification software automates these processes, reducing call handling times and improving overall efficiency. Agents can focus on resolving customer issues rather than spending valuable time on identity checks. The result is faster resolutions, happier customers, and lower operational costs.
-
Ensure Compliance Regulatory requirements like GDPR, HIPAA, and PCI DSS demand robust security measures to protect sensitive customer information. Call verification software helps businesses meet these requirements by ensuring that only verified callers gain access to data or services. This not only protects against legal and financial penalties but also demonstrates a company’s commitment to adhering to industry standards, further boosting credibility and trust.
Threats Addressed by Call Verification
Call verification plays a crucial role in protecting call centers and voice networks from a wide range of threats.
-
Caller ID Spoofing Fraudsters often manipulate caller ID information to make it appear as though the call is coming from a trusted source, such as a bank, government agency, or even the call center itself. This tactic deceives agents and customers, allowing attackers to gain access to sensitive information or commit fraud. Verification technologies combat spoofing by validating the true origin of the call. These systems ensure that the displayed caller ID matches the actual source.
-
Account Takeovers Attackers impersonate legitimate customers by using stolen credentials or personal information gleaned from data breaches or phishing attacks. Once they gain access, they can steal funds, make unauthorized transactions, or steal sensitive account details. Call verification tools, such as multi-factor authentication (MFA) and voice biometrics, adds multiple layers of security, making it significantly harder for attackers to succeed.
-
Vishing and Social Engineering Scammers frequently use social engineering tactics like voice phishing, or vishing. This involves posing as a trusted individual or organization to trick agents into revealing confidential information, such as passwords, account numbers, or authentication codes. Call verification systems help identify and block suspicious calls by analyzing caller behavior, speech patterns, and other metadata. These tools flag unusual activities and prevent fraudulent calls from reaching agents, effectively mitigating the risks of these manipulative tactics.
-
Telephony Denial of Service (TDoS) Attacks TDoS attacks overwhelm call centers with a high volume of fake calls, disrupting operations and blocking legitimate customers from getting through. These attacks can lead to significant financial losses and delays in service. Call verification systems filter out illegitimate traffic in real-time, ensuring that genuine calls are prioritized. By detecting and blocking TDoS attacks, businesses avoid costly service disruptions.
-
Data Breaches Weak authentication systems leave sensitive customer and business information vulnerable to attackers. Once accessed, this data can be used for identity theft, financial fraud, or other malicious activities. Call verification technologies ensure that only authorized callers can access confidential data by validating their identity and the legitimacy of the call.
Technologies Used in Call Verification
Call verification relies on advanced technologies to deliver robust security and ensure that only legitimate callers can connect to agents or access sensitive systems.
-
Knowledge-Based Authentication (KBA) KBA verifies a caller’s identity by requiring them to answer security questions or provide personal information stored in the system, such as account details or recent transactions. While widely used and easy to implement, KBA has significant drawbacks. Attackers can often obtain answers to KBA questions through data breaches or social engineering, making this method vulnerable to exploitation. Additionally, because customers often find repetitive KBA questions frustrating, many businesses are replacing KBA with more advanced technologies.
-
Automatic Number Identification (ANI) Validation ANI validation compares the incoming call's phone number against a trusted database to confirm that it’s legitimate. While it’s effective for repeat callers, ANI is less reliable for unknown or new numbers and requires additional layers of validation to counter spoofing.
-
STIR/SHAKEN Protocols STIR (Secure Telephony Identity Revisited) and SHAKEN (Secure Handling of Asserted Information Using Tokens) are protocols designed to validate caller ID information. They use digital certificates to confirm that the caller ID displayed on the recipient’s phone matches the actual source of the call. This technology effectively blocks spoofed calls, a common tactic used by fraudsters to impersonate trusted entities like banks or government agencies. STIR/SHAKEN is particularly effective for rebuilding trust in caller ID systems, though it may not be available on legacy networks or international calls.
-
Multi-Factor Authentication (MFA) MFA enhances security by adding multiple layers of verification to confirm caller identity. It typically combines something the caller knows (e.g., a PIN or password), something they have (e.g., a one-time password sent to their mobile device), and something they are (e.g., a biometric identifier like their voice). This multi-layered approach makes it extremely difficult for fraudsters to gain access, even if they have partial information about the caller. While it requires additional infrastructure and may increase call duration slightly, MFA is an essential component for securing high-risk transactions or accounts.
-
Voice Biometrics Voice biometrics authenticate callers by analyzing unique vocal characteristics, such as pitch, tone, cadence, and pronunciation. This technology can operate actively, requiring the caller to speak specific phrases, or passively, analyzing natural conversation during the call. While it’s sensitive to background noise and call quality issues, this technology is widely regarded as one of the most effective tools for combating fraud in call centers.
-
Behavioral Analytics Behavioral analytics leverage artificial intelligence to monitor and analyze caller behavior and speech patterns for signs of fraudulent activity. These systems evaluate factors like speaking cadence, navigation habits, and interaction tendencies to detect anomalies that might indicate fraud. By continuously learning from normal caller behavior, behavioral analytics can adapt to evolving threats while maintaining a frictionless experience for legitimate users.
-
AI-Based Authentication AI-based authentication uses machine learning to analyze a wide range of data points, including voice patterns, metadata, and call history, to verify caller identities. This technology continuously improves over time, making it highly effective for detecting complex fraud schemes and adapting to emerging threats.
