The fixed line between real and fake
Detect social engineering and impersonation attempts on live phone calls and video meetings in real time.
Live protection
One tap activates Meridian. The live conversation is analyzed for social engineering signals — urgency pressure, identity avoidance, authority claims, unusual requests — and a real-time authenticity score tells your employee exactly how much to trust the person on the other end.
Below the score, one line of plain English explains exactly what tactic is being used. No security jargon. No interpretation required. The employee knows what is happening and what to do next.
A caller claiming to be from your software vendor. The voice is calm. The request sounds routine. But Meridian has detected urgency language designed to prevent questioning, two deflections when asked to verify identity, and a request pattern inconsistent with how your actual vendor operates. Score: 19% authenticity.
Caller is using urgency pressure and has avoided identity confirmation twice.
The problem
The security industry spent twenty years building walls around the technical attack surface and left the human one completely undefended. Attackers noticed. They stopped writing exploit code and started making phone calls.
Your firewall is enterprise grade. Your endpoint protection is current. Your team passed the compliance training six months ago and got perfect scores. Then someone called pretending to be from IT support and walked straight through the front door.
How it works
Your employee is on a call. The voice is calm. The request sounds reasonable. But the pressure is slightly off — just enough to make them hesitate. They open Meridian. One tap.
The live audio is transcribed and scanned for social engineering signals every few seconds. Urgency manufacturing. Authority impersonation. Identity avoidance. Emotional manipulation. Each tactic is identified, weighted, and scored as the conversation unfolds.
A live authenticity score appears — 0 to 100 — updating in real time. One line of plain English explains exactly what the caller is doing: "Caller is using urgency pressure and has avoided identity confirmation twice." Your employee now sees the call for what it is.
Detection
Social engineering works by exploiting the cognitive shortcuts that make humans efficient — trust of authority, response to urgency, desire to be helpful. Attackers weaponize these instincts. Meridian detects the specific language patterns they use to do it.
"We need this resolved in the next ten minutes or your account will be suspended." The time pressure is fabricated. The goal is to prevent your employee from thinking clearly or asking questions that would expose the caller.
"This is Microsoft support." "I'm calling from your bank's fraud department." Claims of role, rank, or organization designed to trigger automatic deference and bypass the scrutiny a stranger would normally receive.
Legitimate callers from legitimate organizations can verify their identity when asked. Attackers cannot — so they deflect, redirect, or create pressure that makes asking feel uncomfortable. Meridian tracks every deflection.
For businesses
Every employee gets the same defense layer. You get visibility into the attacks targeting your organization — who is being targeted, how often, and with what tactics. The human attack surface becomes measurable for the first time.
Meridian does not replace human judgment. It protects it. No passive monitoring. No surveillance. The employee controls when Meridian activates. When a call is clean, the data is discarded. When a call is flagged, the analysis is retained for incident reports and to sharpen detection for every customer. Clean data is never stored. That is the line.
Every flagged call across your entire team in one view. See which employees are being targeted, how frequently, and which specific social engineering tactics are being used against your organization.
Every analysis generates a full report written clearly enough to forward directly to a manager, an insurance provider, or law enforcement. Final score, complete signal log with timestamps, and a recommended next action.
Over time, Meridian builds a profile of the tactics being used against your specific organization. You see whether attack frequency is increasing, what changed, and what is new.
Any analysis can be flagged as a suspected attack with one tap. Your IT manager or security lead receives an immediate alert with the full call summary and signal log attached.

Meridian makes sure it ends there too. The core protection is free for individuals. Businesses pay for organizational visibility and intelligence. See it work on a live call.
