Plainsea
The Agentic Penetration
Testing Platform.
A complete offensive security platform combining practitioner-led workflows, autonomous agentic testing, and enterprise-grade governance, purpose-built to operate as a continuous security capability.
Core Capabilities
What Plainsea Delivers
Plainsea’s capabilities cover the full penetration testing lifecycle to help security teams and pentesting providers operate at the speed of modern exposure.
Unified Pentest Lifecycle
From scoping to remediation verification, every phase of your penetration test follows a structured, repeatable workflow - whether delivered by a human, an AI agent, or both. Your team moves faster without compromising quality or control.
Agentic AI Penetration Testing
Plainsea's agentic AI is a purpose-built multi-agent system. Specialized agents handle mapping, execution, and analysis - each with a distinct role. A dedicated orchestrator directs the work, memory builds across every cycle, and human-in-the-loop controls keep you in charge at every critical decision point.
Intelligent Risk Prioritization
Your findings are ranked by confirmed exploitability and real-world business impact, going beyond CVSS scores to show you what poses actual risk in your environment and where your remediation effort will have the greatest effect.
Dynamic & Customizable Reporting
Your reports are generated automatically as testing runs. Customize templates, formats, and evidence standards to meet the specific requirements of your stakeholders, whether that is your board, auditors, regulators, partners, or customers.
Agentic Safety Controls
Before any test runs, you define the scope, permitted actions, and intensity. During execution, human-in-the-loop interceptors surface critical decisions for your approval before the agent proceeds. Your team stays in control at every stage of the process.
Delta Testing
When something changes in your environment - a deployment, a fix, a configuration update - Plainsea tests exactly what changed. Context and findings carry forward across every cycle, so each test builds on the last and your remediation is confirmed, not assumed.
How It Works
The Loop That Closes the Exposure Gap
Six stages. One continuous cycle. From scoping through validated remediation - Plainsea keeps the loop closed.

Define authorized targets, set the rules of engagement, and configure intensity boundaries. For Agent engagements, this is where the deterministic safety envelope is established - the boundaries the AI cannot exceed.
Use Cases
Built for How Security Actually Operates
Plainsea fits into the frameworks and workflows your security program already runs - and closes the validation gaps they leave behind.
Run Continuous Offensive Testing Without Constraints
Frequent, structured penetration testing is essential but hard to orchestrate and dependent on scarce expertise. Use Plainsea to run continuous offensive testing without scheduling constraints or limited human availability holding you back.
