Crosslayer Labs

Product & Competitive Intelligence

Invented the MPIC standard securing every HTTPS connection, now building multi-layer cyber defense.

Company Overview

Builds a unified cybersecurity platform that discovers, monitors, and defends organizations' Internet presence across DNS, BGP, TLS, and application layers. Invented the MPIC standard now securing all major HTTPS connections worldwide.

Competitive Advantage & Moat

Product Roadmap & Public Announcements

MPIC standard adopted by CA/Browser Forum (mandated March 2025). Multi-layer monitoring across DNS, BGP, TLS, JavaScript. Actionable alerts with root cause analysis and remediation recommendations. Targeting healthcare, cryptocurrency, and banking/fintech verticals.

Signals & Private Analysis

Active R&D in ML-driven anomaly detection and multi-layer signal correlation. Open MPIC Project provides open-source implementations used in production by 1.5M+ certificates. Princeton ecosystem ties for deep-tech funding. Prateek Mittal's research also enhanced security of deployed LLMs (GPT 3.5 and GPT4V at OpenAI).

Product Roadmap Priorities

Multi-layer anomaly detection
Improving
Risk Reduction
IT-Security

Real-time anomaly detection across DNS, BGP, TLS, and application layers to identify network outages, hijacks, and infrastructure compromises before they escalate.

In Plain English

It watches every layer of your Internet connection simultaneously so it can spot an attack the moment something looks even slightly off, like a security guard with eyes on every door at once.

Analogy

It's like having a doctor who checks your blood pressure, heart rate, temperature, and bloodwork all at once instead of four separate specialists who never talk to each other.

Distributed issuance corroboration
Improving
Product Differentiation
Product

Multi-Perspective Issuance Corroboration (MPIC) uses distributed vantage points and ML-driven pattern recognition to detect and block fraudulent TLS certificate issuance attempts in real time.

In Plain English

It double-checks every new website security certificate from multiple locations around the world so no one can trick the system into issuing a fake one.

Analogy

It's like requiring three different notaries in three different cities to independently verify your identity before you can get a passport, so no single forger can fool the system.

Intelligent attack surface mapping
Improving
Operational Efficiency
Engineering

Automated discovery and continuous mapping of an organization's external attack surface using ML-driven asset enumeration, dependency analysis, and risk scoring across APIs, web services, and infrastructure.

In Plain English

It automatically finds every door, window, and hidden entrance to your online presence that you didn't even know existed, then tells you which ones are unlocked.

Analogy

It's like hiring a drone to fly around your entire property every hour and flag every new crack, open gate, or suspicious person—instead of walking the perimeter yourself once a quarter with a clipboard.
