Core Features

Empower your security strategy

AI-driven pentesting

You can’t protect what you can’t see— discover what you left behind when moving fast and breaking things

List of security vulnerabilities with severity levels: Cross Site Scripting (7), SQL Injection (4), Remote Code Execution (6) marked Critical, Horizontal Privilege Escalation (3) and Misconfigured Permissions (2) marked High, with Misconfigured Permissions also labeled New.
Rapid onboarding

Go from 0 to a pentest report within two weeks

Step 1 of attack surface scan showing domain input fields with primary domain technosolutions.com and an optional related domain with a disabled input technosolutions.eu, plus a bright yellow Next button.
Attack replay

Instantly re-test fixes and get to a clean pentest report in hours rather than weeks

UI panel showing Insecure Direct Object References (IDOR) with medium severity, CVSS score 5.2, and buttons for 'Open ticket' and 'Replay'.
Test transparency

See what Sybil finds in real-time instead of waiting for a PDF that nobody reads

Security scan section showing scan completed on Feb 2 at 5:08 PM. Exploit section with 2-3 days remaining lists Authentication and Authorization Failures, Broken Access Control with check marks, Cryptographic Failures with hourglass, and several tasks grayed out.
