When you deploy an AI voice agent, you are entrusting a vendor with your customer conversations - names, phone numbers, account details, health information, and the audio recordings of actual calls. The vendor's security posture becomes your security posture. A breach at the vendor exposes your customers' data, triggers your notification obligations, and damages your reputation. This 50-point assessment template helps you evaluate vendor security before signing a contract, not after an incident. ## Why Vendor Security Assessment Matters Third-party vendor risk is one of the largest and most underestimated security risks organizations face. Research consistently shows that 60-65% of data breaches involve a third-party component - a vendor, supplier, or partner whose systems were compromised. For AI voice agent deployments, the vendor relationship is particularly high-risk because the vendor processes sensitive customer data in real time. Your AI voice agent vendor touches every part of your customer data lifecycle. They receive inbound calls with caller information. They process speech through AI models. They may store call recordings, transcripts, and metadata. They integrate with your CRM, calendar, and other systems. And they handle the infrastructure that keeps the service running. A security failure at any point in this chain can expose your customer data. Regulatory frameworks explicitly address vendor risk. GDPR requires data processing agreements with vendors processing personal data. HIPAA requires business associate agreements. SOC 2 and ISO 27001 both include vendor management as audit areas. Conducting a formal security assessment before engaging a vendor is not just good practice - it is a regulatory expectation. ## Data Handling and Storage The first and most critical assessment category covers how the vendor handles your data - what they collect, where they store it, how long they keep it, and who can access it. These questions establish the baseline understanding of your data exposure. Question 5 is particularly important for AI voice agent vendors. Many AI companies use customer data to train and improve their models. While this may improve the service over time, it means your customer conversations are being processed beyond the immediate call handling purpose. This may violate GDPR purpose limitation requirements and your own privacy commitments to customers. Always insist on an explicit opt-in model for training data usage. ## Encryption Standards Encryption protects data in two states: in transit (moving between systems) and at rest (stored on disk). Both are essential. Voice AI systems have multiple data transit paths - between the caller and telephony provider, between the telephony layer and AI processing, and between AI processing and storage - each requiring its own encryption. Pay special attention to voice media encryption. Standard HTTPS encryption protects web traffic, but voice calls use different protocols. Secure Real-time Transport Protocol (SRTP) is the standard for encrypting voice media. If the vendor uses unencrypted RTP for voice transmission, the actual audio of customer conversations travels across the internet in the clear - accessible to anyone who can intercept the traffic. ## Access Control and Authentication Access control questions determine who can reach your data within the vendor's organization and through the vendor's platform. A vendor with excellent encryption but poor access controls still puts your data at risk - from insider threats, compromised employee accounts, and overly broad access permissions. ## Compliance and Certifications Compliance certifications provide independent validation that a vendor meets recognized security standards. While certifications do not guarantee perfect security, they demonstrate that the vendor has invested in security processes and subjects themselves to external audits. SOC 2 Type II is the most relevant certification for voice AI vendors. It covers security, availability, processing integrity, confidentiality, and privacy - all critical for a service handling customer conversations. Type II (versus Type I) means the controls were audited over a period of time (typically 6-12 months), not just at a single point. Always request the actual SOC 2 report, not just a certification badge on the vendor's website. ## Incident Response and Breach Notification When a security incident occurs at the vendor, you need to know about it quickly enough to meet your own notification obligations. GDPR gives you 72 hours from awareness to notify your supervisory authority. If the vendor takes 71 hours to tell you about a breach, you have almost no time to assess and report. ## AI-Specific Security Controls Traditional vendor security assessments cover infrastructure and data handling but miss risks specific to AI systems. Voice AI vendors need additional scrutiny around model security, prompt engineering safeguards, and AI-specific attack vectors. ## Using the Assessment Template This 50-question template is designed to be used as a living document during vendor evaluation. Not every question will be equally relevant for every organization - a dental practice and a financial institution have different risk profiles. Prioritize the questions that matter most for your data types, regulatory obligations, and risk tolerance.
