Plainsea
AI-powered PTaaS platform augmenting pentesters with automated, continuous validation.
Vendor Information
Plainsea Overview
Plainsea is an AI-powered Penetration Testing as a Service (PTaaS) platform purpose-built for continuous penetration testing that transforms traditional point-in-time assessments into scalable, ongoing security validation. Born from operational experience at AMATAS, a CREST-certified global MSSP, Plainsea was developed to solve real-world pentesting challenges: high costs, scalability constraints, inconsistent reporting, talent shortages, and inability to keep pace with cloud-native architectures and API sprawl. Founded in 2022 by Marko Simeonov (CEO) and Angel Angelov (CTO), the platform delivers augmented penetration testing combining smart automation with continuous validation and expert human oversight, enabling penetration testers to focus on identifying complex security issues rather than spending weeks on repetitive tasks. The platform demonstrated its "5-Minute Penetration Test" capability at Infosecurity Europe 2024, enabling organizations to achieve 30% faster project turnaround and 45% cost reduction through streamlined junior expert onboarding.
Core capabilities span the complete pentesting lifecycle within a centralized interface: scoping, automated asset discovery, vulnerability assessment backed by proprietary CVE database from decade+ CREST-certified experience, live collaboration portals, automated reporting with AI-powered summarization reducing report generation burden by 6x, and zero-day retesting workflows. The platform features automated infrastructure mapping, real-time risk assessment using CVSS 3.1 and OWASP methodologies, custom runbook templates for NIST SP 800-171, PCI DSS, HIPAA, and ISO 27001 compliance frameworks, and client-centric portals providing end-clients direct access to project status, findings, and real-time vulnerability updates. AI-powered writing assistance and technical writeup repositories accelerate junior pentester onboarding, while integrations extend to threat intelligence platforms, vulnerability scanners, and project management systems including Jira and ServiceNow.
Plainsea enables MSSPs to adopt continuous pentesting business models, internal security teams to manage expanding attack surfaces with limited resources, and enterprises to align security testing with DevOps/CI-CD pipelines for strategic risk-based validation beyond compliance checkboxes. Backed by Ocean Investments and expanding into US and UK markets in 2025, the platform serves finance, healthcare, technology, and critical infrastructure sectors. Featured as the only full executive interview in The Recursive CEE Cybersecurity Report, Plainsea positions itself as a leader in Central and Eastern Europe's cybersecurity innovation wave, providing world-class security validation infrastructure to organizations transitioning from reactive to proactive security postures.
Key Capabilities
Standardized capabilities mapped to this product's security niche
Initiates penetration testing engagements through a platform interface without requiring a new statement of work for each test, enabling testing at the cadence of development releases.
Automatically re-executes test cases for specific findings after the reported remediation deadline, confirming closure without scheduling a separate engagement.
Manages asset scope definitions, scope change approvals, rules of engagement, and testing windows through a persistent platform interface rather than per-engagement documentation.
Executes penetration testing techniques continuously against defined scope, identifying new attack paths as the environment changes rather than capturing a point-in-time view.
Executes attack techniques using non-destructive payloads (read-only filesystem access, non-weaponized exploitation), designed to confirm exploitability without causing service impact.
Routes high-confidence automated findings to human pentesters for validation, chaining, and exploitation depth that automated tools cannot achieve.
Automatically re-tests findings after the reported remediation deadline to confirm the vulnerability has been closed, without scheduling a new engagement.
Manages all customer environments from a single platform instance with complete data isolation between tenants, the fundamental architectural requirement for any MSSP platform.
