They don't hack in. They call your help desk.
AurisGuard stops phone and text social engineering against your people: your help desk, your executives, and your finance team. Verify who is really on the line, catch the attempt, and put it in front of your security team.
Built for security teams at companies with 1,000 to 20,000 employees.

The threat
The fastest way into your company is a person with a phone.
Email security got good, so attackers moved to the channels nobody is watching: phone calls, texts, and messaging apps. They aim at the people whose job is to help.
-
Fake employee calls the help desk
An attacker phones your IT help desk pretending to be an employee who's locked out. The agent resets their password or MFA (two-step login), and the attacker signs in as that employee.
Caller: "Hi, it's Jordan in Finance. I got a new phone and I'm locked out. Can you reset my MFA?"
This is how attackers got into MGM Resorts and Caesars in 2023, and Marks & Spencer in 2025. Sources: TechCrunch, BleepingComputer.
-
Fake executive texts or calls
A message from the "CEO" arrives from a new number, or a video call shows a cloned face and voice. The request is always urgent and confidential: send a wire, buy gift cards, share a file.
Text from "CEO": "In a board meeting, can't talk. Need a wire sent before 5pm. Keep this between us."
In 2024, an employee at engineering firm Arup sent about $25 million after a video call with a deepfaked CFO. Source: CNN.
-
Fake vendor changes bank details
Someone posing as a supplier or executive calls accounts payable and asks them to update bank details or rush a payment.
Caller: "We've switched banks. Please send this month's payment to our new account."
No malware and no phishing link. Just a convincing phone call.
The gap
Your security stack wasn't built for a phone call.
In the moment, the employee has no fast way to check who they're talking to, and your security team never finds out it happened.
- Email securityThe attack never touches email.
- Caller ID and spam labelsEasy to fake, and they say nothing about who is really calling.
- Security awareness trainingTeaches people to be suspicious, but gives them nothing to do in the moment.
- Help desk security questionsThe answers are on LinkedIn, in breach dumps, and at data brokers.
- Deepfake detection aloneNeeds the audio, and falls behind with every new voice-cloning model.
How it works
Verify the person. Catch the attempt. Alert your team.
-
01 · Verify
Confirm identity with one tap
Before a password reset or a wire transfer, AurisGuard asks the real person to confirm on a channel you already trust.
- Verification requests in Teams or Slack
- Known phone numbers for each executive
- A "no" or no answer stops the request
-
02 · Detect
Score every call and text
Number reputation, known-bad and known-good lists, and AI analysis of what was said.
- Employees report suspicious contacts in one click
- Live caller risk for help desk agents
- A plain-English reason for every verdict
-
03 · Alert
Turn every attempt into a case
Your security team sees who was targeted, who was impersonated, and what to do next.
- Triage, assign, and close cases
- Send alerts to your SIEM (OCSF format)
- Analyst feedback sharpens detection
Deepfake detectors are in an arms race. We verify the identity instead of judging the voice.
