Infosecurity Europe 2025, held at ExCeL London from 3–5 June, brought together global cybersecurity leaders to showcase innovations, exchange insights, and explore the fast-evolving threat landscape. Among the most talked-about names in the Startup Zone was Plainsea, which drew consistent attention with a bold, streamlined message: traditional penetration testing is broken – and it’s time to fix it.
Over the course of the three-day event, Plainsea’s booth became a magnet for security professionals looking to modernize their approach to offensive security. The company’s AI-powered platform for continuous pentesting, designed for both MSSPs and in-house security teams, sparked strong interest thanks to its blend of real-time visibility of the evolving attack surface, streamlined workflows, and a newly unveiled AI Companion – available for demo at the event for the first time.
A clear highlight of Plainsea’s presence came on the first day with the fully packed session “Stop! You’re Doing It Wrong! Here’s How to Pentest Smarter,” delivered by CEO Marko Simeonov and CTO Angel Angelov on the Cyber Startup Stage. The session paired sharp industry commentary with a live product demo that showcased how Plainsea replaces legacy pentesting bottlenecks with a scalable, intelligent workflow.
“Imagine Plainsea as the central nervous system of your pentesting team,” Simeonov told the audience. “Just like the human nervous system, Plainsea connects everything. It senses what matters, processes information instantly, coordinates actions, and helps the whole body respond – faster, smarter, and in sync. You wouldn’t build a body without a nervous system. So why build your security operations without one?”
This sentiment struck a chord with attendees frustrated by the operational drag of traditional testing. Across both the packed Startup Stage session and booth demos, the company showcased how its platform transforms pentesting into an ongoing, collaborative process. From assessment templates and asset management to centralized findings, real-time communication, and dynamic report generation, Plainsea offers one platform with all the tools penetration testing providers need to streamline delivery, enhance visibility, and reduce time-to-remediation – without losing control over the testing process. Crucially, its AI-assisted capabilities further signal a shift toward smarter, more adaptive testing workflows.
As industry conversations increasingly gravitate toward AI’s role in cybersecurity, Plainsea’s message felt especially timely. This year’s event saw widespread dialogue around the need for intelligent automation, as security teams grapple with growing complexity and resource constraints. Plainsea’s introduction of its AI Companion – designed to support testers with real-time guidance, contextual insight, and automated report generation – was well-aligned with this trend.

The momentum surrounding Plainsea at Infosecurity Europe 2025 also reflected a broader industry appetite for more efficient, and more scalable approaches to penetration testing. With a platform that addresses both the strategic and operational gaps in modern pentesting, Plainsea positioned itself not just as a tool provider, but as a catalyst for change in how offensive security is delivered.
