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.
