Tech Stack

Integrations

Voice AI agentsChat AI agentsConversational AI systemsCustomer service platformsIVR systems

AI/ML Capabilities

Proprietary adversarial simulation and red teaming models capable of generating sophisticated prompt injection attacks, bias detection, toxicity assessment, and sensitive data extraction attempts across multiple vulnerability categories.

Technical details limited in available sources; based on product capabilities and service descriptions from official documentation.

Use Cases

Enterprise Security Teams in BFSI
Validate that voice banking agents are secure enough so they can't be jail broken or tricked into doing an unauthorized transaction while maintaining PCI DSS compliance prior to production deployment.
Healthcare Organizations
Test conversational AI systems for HIPAA compliance, provide tests for bias in medical advice and prevent sensitive patient data from leaking in automated patient interaction systems.
Legal Tech Companies
Make sure AI legal advisors aren't vulnerable to being manipulated into giving unauthorized legal advice or violating the attorney client privilege by using adversarial testing.
SaaS Companies with AI Customer Service
Detect attempts to bypass paywalls, social engineering vulnerabilities, and verify that customer service bots will remain in a consistent security position throughout all interactions.
Startups Building Conversational AI
Allow cost effective security validations through automated red teaming pre-series A or customer deployments to reduce manual security testing overhead.
E-commerce Platforms with Voice Checkout
Test voice shopping agents for vulnerabilities to making unauthorized purchases, fraud attempts and enforcing correct authentication mechanisms.
NOT FORReal-Time Trading Systems
Inappropriate โ€“ The Cekura's simulated environment-based testing does not allow for the sub-millisecond response times needed for production trading execution.
NOT FORConsumer Chatbot Builders Without Compliance Requirements
Possibly excessive โ€“ RTaaS and Enterprise focused red teaming services for regulated industries may be too expensive for low risk consumer applications.
NOT FOROrganizations With Mature AI Security Programs
For those with an internal adversarial testing team that is doing similar testing to Cekura, Cekura has limited additional value. However, for companies looking to build out their initial AI Security infrastructure, there are many benefits.

Faq

Cekura uses artificial intelligence to generate thousands of potential scenarios to test your Voice or Chat Agent's responses. Cekura can also simulate multiple users of different demographics based upon accent, background noise, etc., and allows you to measure response time, customer satisfaction (CSAT), latency, and how well it follows instructions. Because of this, Cekura enables you to launch a fully tested and validated solution in a matter of days versus months.

The traditional method of manual Quality Assurance (QA) is extremely slow, very inconsistent, and usually will miss all edge cases. Typically, manual QA would take weeks to perform a small number of spot checks, whereas Cekura can automate tens of thousands of tests in just a few minutes and provide you with metrics driven evaluations, regression testing, and real-time observability so that you can proactively ensure the reliability of your solutions.

Yes, Cekura provides Enterprise Grade Security through its In-VPC (Virtual Private Cloud) Deployment Model, Single Sign On (SSO), Role Based Access Control (RBAC), and Compliance Support for HIPAA and PCI-DSS. Therefore, Cekura is designed to be scalable while providing the safety needed for regulated industries such as Healthcare and Banking.

Yes, Cekura integrates directly with Continuous Integration / Continuous Deployment (CI/CD) frameworks for regression testing when you make changes to either prompts or models. Additionally, Cekura supports scheduled testing using Cron Jobs and will automatically convert failed production calls into new evaluators.

Cekura currently supports over 70 Teams across various industries including Healthcare (HIPAA), Banking (PCI-DSS), Retail and Enterprise Contact Centers. Cekura provides validation of workflows such as Booking, Refunds and Compliance Checks across both Voice and Chat Agents.

Yes, Cekura provides Unified Evaluation for both Voice AI (accent, noise) and Chat AI Agents. Cekura covers the entire process from generating Adversarial Scenarios, Measuring Performance using Metrics, Providing Real-Time Observability, and Monitoring both Channels.

Yes, Cekura provides Real-Time Observability of your Solution with Alerts for Drop Offs, Latency Spikes, and Failures delivered via Slack. Cekura also includes Performance Analytics, Diagnostics, and Auto Test Generation from Actual Interactions.

Cekura Pricing and Rate Limits are publicly available but Exact Pricing requires contacting Sales. Custom Scenarios for Industry Specific Testing may require the use of Forward Deployed Engineers at an additional cost.

Expert Verdict

Cekura provides an automated way for a red teaming and observability process for conversational AI agents as they address the manual QA bottleneck issues that exist today with scalable scenario generation and metrics-driven evaluation for their enterprise-ready offering with compliance support making them a good fit for regulated industries using voice or chat AI at large scales.

Alternatives

  • โ€ข
    Pareto AI: Cekura is an AI Agent Testing Platform with Synthetic Data & Workflow Validation. While Cekura can generate similar Scenarios as Pareto AI, it focuses more on Voice. Therefore, Pareto AI may be a better fit for Chat-First Agent Teams requiring Quick QA.
  • โ€ข
    Honeycomb: Honeycomb is an Observability Platform with robust AI Tracing and Alerting capabilities. It is best suited for Production Monitoring and lacks Cekura's Pre-Deployment Red Teaming and Scenario Automation features. If you require Debugging Live AI Systems, Honeycomb would be the most suitable option.
  • โ€ข
    Vapi: VAPI is a Voice AI Platform with Built-In Testing Tools. While VAPI provides more End-to-End Voice Deployment options compared to Pure Testing, it also offers Easier Setup for Calls. This makes VAPI a better fit for Teams Building Voice Agents as opposed to Teams Simply Testing Voice Agents.
  • โ€ข
    Promptfoo: PromptFoo is an open-source LLM Evaluation Framework for Prompts and Models. While PromptFoo is free and developer-focused, it does require Setup. It lacks Voice Simulation and Enterprise-Level Observability making it less suitable for non-cost conscious Dev Teams.
  • โ€ข
    Helicone: Helicone is an LLM Observability platform with Metrics, Tracing and Alerts. It excels at Production Monitoring and Cost Tracking but is limited when compared to Cekura's Pre-Launch Testing Capabilities. Therefore, if your organization requires LLMOps without Voice Requirements, Helicone is likely the better choice.
