The Problem

Security teams are drowning

Too many tools, too many alerts, no prioritization. Your team wastes hours triaging false positives while real threats slip through the cracks.

Alert Fatigue

Average security teams face 10,000+ alerts per day. Over 70% are false positives, burying the real threats under noise.

Tool Sprawl

Separate scanners for web, database, ERP, and network. Each with its own dashboard, its own format, its own blind spots.

No Context

CVSS scores alone cannot tell you which vulnerability an attacker will exploit first. Without attack path context, prioritization is guesswork.

How It Works

From zero to protected in three steps

01

Connect Your Assets

Add URLs, database endpoints, ERP systems, or cloud accounts. ShieldGraph enumerates subdomains, exposed ports, and related assets from each target you connect.

02

Continuous Scanning

Purpose-built scanners for web, database, ERP, cloud, and port exposure run on your schedule — daily, weekly, or on demand. All findings land in a single dashboard.

03

Prioritized Results

AI ranks findings by exploitability and business impact. The attack graph shows exactly how vulnerabilities chain together into exploitable paths.

Features

Everything you need to secure your stack

One unified platform replacing your fragmented security toolkit.

Attack Graph Visualization

See how vulnerabilities chain together into exploitable attack paths. Interactive graph shows lateral movement possibilities across your infrastructure.

Multi-Asset Scanning

Scan web apps, PostgreSQL / MySQL / MongoDB / Redis, SAP, Dynamics 365, AWS / GCP / Azure, and more. 30+ specialized scanners in six packs.

Asset Enumeration

Point ShieldGraph at a domain and it enumerates subdomains, exposed services, and open ports so new-to-you assets surface on the next scan.

AI Prioritization

CVSS scores enriched with CISA KEV data and asset criticality scoring. Know which vulnerability to fix first based on real-world exploitability.

Scheduled Scans

Daily, weekly, or continuous automated scanning with configurable alerts. Never miss a new vulnerability in your changing infrastructure.

Team Collaboration

Role-based access control with Owner, Admin, Analyst, and Viewer roles. Assign findings, track remediation, and report to leadership.

Pricing

Simple, transparent pricing

A free grade for everyone. Fixes and monitoring when you're ready.
