TEST YOUR EMPLOYEES AGAINST AI VOICE ATTACKS BEFORE REAL
ATTACKERS DO
A vishing simulation calls your employees the way an AI-driven attacker would: a natural conversation, a believable pretext and a local number. Callstrike runs thousands of these calls at once, with consent first, and turns every call into training.

A voice your employees know, from a number they would pick up.
Video calls on Zoom, Teams, Google Meet and WhatsApp, in the same platform.
Our AI agents conduct realistic voice phishing calls that adapt in real time, testing
whether employees can identify and resist sophisticated vishing attacks.

STEP 1
Select from prebuilt scenarios or create custom attack templates. Choose caller personas, target departments, and define success criteria for your simulation.

STEP 2
Our AI bots call your employees simultaneously, engaging in natural conversations designed to extract credentials, sensitive information, or trigger unauthorized actions.

STEP 3
Review detailed analytics including call recordings, transcripts, employee responses, and vulnerability scores. Identify high-risk individuals and departments.

STEP 4
Automatically assign personalized training to employees based on their simulation performance. Track improvement over subsequent campaigns.
Two Powerful Attack Vectors
Test your organization with both outbound AI calls and live voice impersonation. These
are the two most common vishing techniques used by real threat actors.
AI bots proactively call your employees, impersonating IT support requesting password resets, vendors confirming payment details, or internal teams seeking sensitive data.
A trained operator speaks to your employees in real time in the cloned voice of an executive or supplier, adapting to every answer the way a real attacker would.
Everything your security team needs to run, manage, and scale AI voice phishing campaigns
across the enterprise, no hardware or GPUs required.
Realistic AI Conversations
Advanced language models enable natural, contextual conversations that adapt to employee responses in real-time.
Custom Scenario Builder
Create unlimited attack scenarios with our intuitive template builder. Define personas, scripts, and extraction goals.
Ambient Audio Realism
Add background sounds like airport noise, coffee shops, or office environments to increase attack authenticity.
Global Phone Numbers
Acquire local phone numbers from all US states and 40+ countries directly within the platform.
Caller ID Spoofing
Display legitimate-looking caller IDs with STIR/SHAKEN compliance for maximum pickup rates.
Detailed Analytics
Track every interaction with call recordings, transcripts, response patterns, and vulnerability scoring.

Frequently asked questions
A vishing simulation is a controlled voice phishing call to your own employees, made with their consent, to see whether they would share information or take a risky action when a convincing caller asks. Callstrike places the call with an AI voice that holds a natural conversation, records the outcome, and tells the employee it was a simulation so the call becomes training.
Yes. Callstrike is a vishing simulation tool that calls your own employees with an AI voice from a local number, holds a natural conversation around a pretext you choose, such as the IT help desk or payroll, and records whether they share information. Employees consent first, the caller stops as soon as it is asked to, and the call becomes training.
A vishing test is one round of vishing simulation: Callstrike's vishing simulator calls a chosen group of employees and measures who shares information, who refuses and who reports the call. Teams run one as a baseline, then repeat it to show improvement.
Choose a scenario, select the employees, pick local caller numbers and launch. The campaign places and paces the calls and reports every outcome in the dashboard, with follow-up training for employees who were caught out.
Yes. Your team can run Callstrike itself, and partners and MSSPs run it as a managed vishing simulation service for their clients. For the most realistic tests, live operators can join the call with a cloned voice.
Most security awareness platforms were built for email and added voice later, often as a recorded message or a fixed script. Callstrike is purpose-built for AI-era attacks: a live AI caller that listens and answers, cloned voices, local caller numbers, and live deepfake video calls on Zoom, Teams, Google Meet and WhatsApp, all in one platform.
Our AI uses advanced language models that enable natural, contextual conversations. The bots adapt to employee responses in real time, ask follow-up questions, and handle objections just like a human caller would. Most employees cannot distinguish our AI calls from real human callers.
Employees consent before any call is placed. The AI caller stops as soon as an employee asks it to. When the call ends, employees are told it was a simulation, in the call itself, by a follow-up awareness email, or both. Scenarios built on threats, extortion or distress are blocked before they can be saved.
A phone call from a local number. The caller presents as someone plausible, such as the IT help desk, payroll or a courier, and asks for something an attacker would want. Employees who refuse or report the call pass. Either way, they learn what gave the call away.
When an employee shares sensitive information or takes a risky action during a simulation, they are immediately flagged in your dashboard. You can configure automatic training assignment, send notification emails, or simply log the result for your security team to review.
Yes, you have complete control over scenario design. Create custom personas (IT support, vendors, executives, etc.), write custom scripts, define what information the AI should try to extract, and set success criteria for your specific testing objectives.
You can acquire local phone numbers from all 50 US states and over 40 countries directly within the platform. This allows you to test whether employees are more likely to answer calls from local numbers or specific area codes.
Yes, when conducted with proper authorization. As the organization conducting tests on your own employees, you have the right to assess security awareness. Our platform includes consent management tools and documentation features to ensure your program is properly authorized and documented.
Most organizations launch their first simulation within a day of onboarding. Select a pre-built scenario, upload your employee list, choose your phone numbers, and launch. No technical integration or IT involvement required.
