AI Penetration Testing That
Proves What's Exploitable
Automated, continuous pentesting for your applications and infrastructure - not once a year. Plainsea's AI agents attack within the scope you set, you approve critical steps, and every finding comes confirmed with audit-ready evidence.
SOC 2 Type II · ISO/IEC 27001 · ISO 9001 · Backed by 10+ years of CREST-certified pentesting

The Problem
The Exposure Gap
Exposure is created instantly. Traditional testing can't keep up.
Supply Chain
Business Logic
Distributed Applications
AI-Generated Code
Supply Chain
Supply Chain & Third-Party Dependencies
Every integration expands the attack surface. Most of it is never fully tested - and the exposure compounds with every new dependency.
Business Logic
Business Logic
Logic flaws hide in how features interact. They don't reveal themselves under time pressure - they require patience, depth, and repeated attempts.
Applications
Distributed Applications
The most dangerous vulnerabilities emerge between services, not within them. They are rarely where anyone is looking.
AI-Generated Code
AI-Generated Code
Code is reaching production faster than anyone can reason about it. The attack surface is growing faster than offensive security testing can follow.
This is not a gap that can be closed with more automated scanners, engagements, or AI agent slop. It requires offensive testing that operates at the speed of exposure.Closing this gap requires offensive testing at the speed of exposure.
The Solution
Grounded in Real Penetration Testing. Evolved for the Age of Instant Exposure.
Built on years of hands-on security expertise, Plainsea combines a complete offensive security delivery platform with autonomous reasoning, continuous execution, and full human control to confirm what is actually exploitable, at the speed exposure is created
The Base
The Offensive Security Foundation
The foundation of the Plainsea platform is built to provide the professional framework and delivery standards required for enterprise-grade offensive security. It ensures that every test is built on practitioner-led methodology and delivered with consistent quality.
See How It WorksProfessional Methodology
Enforce a consistent, practitioner-led offensive methodology across every pentest.
Standardized Reporting
Generate high-fidelity documentation and technical evidence that meets board and regulatory requirements.
Practitioner Intelligence
Enhance delivery with embedded reasoning to prioritize findings based on real-world exploitability rather than theoretical scores.
Unified Operations
Standardize delivery, authorization, and reporting across all environments from a single platform foundation.
Continuous Exposure Validation
Define your targets once. Plainsea agentic AI runs penetration testing continuously or on schedule - confirming what is exploitable without waiting for human availability.
Adaptive Attack Execution
Plainsea agentic AI reasons about your environment, chains multi-step attack paths, and adapts to what it finds, delivering the depth of manual testing at AI speed.
Safety by Design
Every action operates within a deterministic safety envelope you define. Critical decisions are validated by a human operator before execution proceeds.
Remediation Verification
Re-test immediately after every fix, confirming that remediation actually closed the exposure, not just patched the finding.
The Evolution
Agentic AI Penetration Testing
Plainsea evolves offensive security testing with agentic AI natively integrating the adaptive reasoning of a human tester, continuous autonomous execution, and confirmed exploitability into every pentest.
See How It WorksWhat do you get
One Platform. Two Missions.
Mode 01
Organization Security Teams
Ease of Use
Define your testing scope and boundaries once. Plainsea handles the rest - reasoning about your environment, executing offensive actions, and delivering confirmed findings. Human-in-the-loop controls keep you in charge at every critical decision point. No offensive security expertise required.
Findings You Can Act On
Every finding that reaches your team is confirmed. You know exactly what is exploitable in your environment, understand the real business impact, and can direct your remediation effort where it actually matters.
Audit-Ready by Default
Every test produces high-fidelity documentation and a complete evidence trail. When your board, auditor, customer, or regulator asks about your security posture, your evidence is current, complete, and ready.
Mode 02
Professional Pentesters
One Unified Platform
Manage all your client engagements from a single platform. Scope, execution context, evidence, and historical results are centralized, so consistency and compounding knowledge build across your entire portfolio over time.
Consistent Service Quality
Every engagement your team delivers meets the same execution, evidence, and reporting standard - whether it is run by a consultant, an AI agent, or a combination of both.
Flexibility in How You Deliver
Match the right delivery mode to each client engagement. Run human-led, AI-assisted, or fully autonomous testing while maintaining the same governance model and evidence standard across your entire operation.
